3D Glasses Related Questions

3D glasses allow their viewers to experience the illusion of three dimensions on a 3D video projector or a 3D television screen. These glasses create a perception of depth in an image. Passive polarized glasses and active shutter glasses are mainly the two types of 3D glasses and each type uses a different technology. They separate the images viewed by both eyes, which is then processed by the human brain and then converted into a 3D image. Below are frequent asked questions on issues relating to 3D Glasses that has been answered by the Experts.

I have a Panasonic TC-P55ST30 TV. What brands of 3D glasses would work with that TV?

To get the correct brand of 3D glasses for your Panasonic TV, you would want to visit http://shop.panasonic.com/shop/model/TC-P55ST30?t=accessories. This website would provide you with options on shutter 3D glasses that are compatible to work with Panasonic. However, it would always be a better idea if you could go through the various sizes of these glasses available on this website before purchasing one. For instance, if you could visit http://www.amazon.com/Panasonic-TY-EW3D3LU-Active-Shutter-Eyewear/dp/B0058SYDUW, you would be able to get the large size option of 3D glasses. You could take their model or the part numbers and check their prices on the website.

I own a Westinghouse TV with model number TX47F430S. The Direct TV is 3D. I can see

two pictures that are placed side by side on my TV screen. What 3D glasses would I

need to view the TV in 3D?


To begin with, your TV does not seem to be 3D capable. Moreover, the model number that you have provided is not going to work with the DirecTV 3D. Usually, when you purchase a new 3D TV, you receive a pair of 3D glasses along with the new set. Therefore, you would find that in many cases these glasses may not work best with brands other than their own. For example, if you have a Samsung 3D TV, you would see that it works best only with your Samsung 3D glasses. However, in this situation, the reason you thought your TV was 3D compatible is because your TV has a 3D comb filter. This filter is mainly used to control the picture noise on your TV and therefore has nothing to do with 3D viewing effect. Moreover, in this particular case, since a 3D image is being played over a non 3D screen, you kept viewing the two pictures side by side. Usually a 3D TV works by combining two separate images on the TV screen. These images take up the entire screen and become blurred. Now the 3D glasses merge these blurred images into a single 3D image.

Can I plug the 3D glasses directly into a TV port on my HD DLP TV to have them work

effectively or do I need a ‘Starter Package’ for this?

Normally, the 3D glasses consist of an emitter, which can be plugged into the four pin ‘Emitter’ port. You can locate that port on your TV’s back. However, if you purchase the 3D glasses kits from Mitsubishi, you would get the emitter and a control cable along with the kit that you can use to connect to your TV. You must also know that the 3D glasses that you receive in the kit are wireless. For more information on these glasses, you could click on http://www.4electronicwarehouse.com/products/mitsubishi/3dc-1000-3d-starter-pack.html.

I want battery operated 3D glasses for my Hitachi 1080p TV. Where can I buy that?


Hitachi does not provide battery operated 3D glasses to begin with. Therefore, you would need to buy a different TV in order to gain a 3D experience in this particular case. Some companies like Samsung, however, does manufacture these battery operated 3D glasses that are meant for the purpose of experimentation. They are manufactured only for some Samsung televisions that are sold with a particular type of Blu-Ray player. Therefore, if you want to experience a 3D viewing effect on your television set, what you would need to have is a new TV set that is 3D enabled. For that it is not at all necessary for the glasses to have power or batteries of any kind.

The concept of 3D is gaining popularity and is being used in movies, video games and televisions. However, it is important to ensure that the 3D glasses are positioned properly and all other equipments are working correctly, if you want to experience a good quality of 3D viewing. Or else, you may have problems like motion blur, brightness reduction, ghosting and so on while viewing the 3D images through these glasses. If you need clarification about your specific situation with respect to issues related to 3D Glasses, you may ask a TV Technician expert to evaluate your case details and provide a technical insight.

Confused Views: 7 alternative uses for 3D glasses

In the wake of Jackass 3D, Matt comes up with seven alternative – and potentially disastrous – uses for stereoscopic spectacles…

7 Alternative Uses for 3D Glasses (With Catastrophic Consequences)

I hate to upset James Cameron, God knows I do. But amongst the many things I took away from Jackass 3D was the knowledge that 3D clearly works best as a novelty. Sorry, J-Cam. I like looking at 3D forests and dragons flying into sky-rocks as much as the next chap, but it doesn’t quite compare to having chunks of 3D faeces flying out of the screen at you. If you’re honest with yourself, I’m sure you’ll agree.

Like any person who wishes to maintain the sacredness of the 3D experience, I limit my 3D cinema visits to only the most essential outings (which, based on this article, include Avatar and Jackass 3D). Therefore, my 3D glasses (which I’m now lucky enough to get to take home with me) are not getting much use. This simply won’t do.

I’ve considered other possible uses for them and have come up with these ideas, all of which are incorrect answers to a question nobody asked.

1. Sunglasses

Because real sunglasses cost upwards of £6 and you’ve already paid for these ones, there’s no reason your 3D glasses can’t multitask and be sunglasses too. My motto has always been ‘Why do one thing well when you can do several things at a sub-standard level?’ I’ve even got a wooden plaque proudly displaying this motto hanging above my desk as I write this. I made it myself, using a piece of old door and a biro. It looks dreadful.

Catastrophe is inevitable because: They offer almost no protection against bright light. Aside from potentially damaging your eyes by putting these glasses on and staring directly at the sun, you might also find yourself temporarily blinded by brightness while driving. Or maybe you use them to protect your vision-balls from the sun whilst on an exotic holiday to a mountainous area. I’ve seen people lose their balance on cinema steps while wearing these glasses. So, on the edge of a cliff or some such would prove problematic and ‘splatty’.

It’s worth noting that it does warn you on the bag that they aren’t actually sunglasses, which is why this is a lazy suggestion as well as a stupid one.

Potential fatalities: Lots. Should the car crash scenario come to be, a high death count can be expected. And should you take a tumble from a great height, there’s no telling who you might land on or who might slip on your liquidy corpse-jam.

2. Creating a false reality

Make tedious, everyday tasks exciting by pretending that they’re simply part of a 3D film. Give your bus journey to work a narrative arc, perhaps involving the driver being an evil robot monster who will explode if that group of annoying teenaged hate-sacks don’t stop playing bad rap music on their phones. Just because you have to live in reality doesn’t mean you have to interact with it!

Catastrophe is inevitable because: People interact with reality for a reason. It’s one of those unfortunate necessities of life. If I could spend all day at home sitting in my pants and an Iron Man helmet making swooshing noises because I’m pretending to fly, then I would. But it would ruin Christmas dinner for the rest of the family in much the same way as you turning up in silly glasses, munching on popcorn and hysterically laughing every time Nan gets a pop culture reference wrong would.

Furthermore, it would trivialise danger. 3D films have taught us that when something long and sharp is flying towards your face, you’re perfectly safe. Reality has, correctly, highlighted that this isn’t the case. By ignoring reality, the chances are that you’re going to end up sticking your head in front of moving arrow or recently fired bullet while going “ooh”.

Potential fatalities: 1. You.

3. Part of a disguise

These 3D glasses surely would come in handy for lurking in bushes or committing any other acts where identifying features, such as sparkling blue eyes that you could get lost in for hours, can cause you to stand out when your victim next sees you, likely in a police lineup.

Catastrophe is inevitable because: This will only work if everyone starts doing it. It won’t be difficult to catch the only criminal wearing 3D glasses, will it?

Police Officer: Would you mind describing the man who waved his genitals at you, madam?

Shaken Victim: He was thin, pale, had fake Star Trek ears, 3D glasses like they give you at the cinema and a blue t-shirt with the Den Of Geek logo on, available for purchase online for only £14 (plus p&p) in a variety of colours and sizes. And while you’re buying one of those, why not treat yourself to a mug for only £8.99?

Police Officer: Is that the man there in the bushes, madam?

Shaken Victim: Yes, it is. Please buy a mousemat.

Alternatively, what if they lure you into thinking you’re watching a crime caper rather than causing one? You’ll get careless. I just don’t see a scenario involving this idea that doesn’t involve some jail time.

Potential fatalities: 100s. If you did find they offered your criminal activities an effective cloak of anonymity, then who knows what you might do. A bloody killing spree with a homemade shiv seems likely.

4. Weaponry

To adapt your 3D glasses into a shiv, you’re going to need to go a bit Blue Peter. I’ll include a handy step-by-step guide, so it’s as simple for you as possible.

Step 1: Snap the arms off of the glasses and put them somewhere safe. Take the section of the glasses with the lenses on, the front bit, and forcibly insert it into your anus. Alternatively, you can dispose of it in any other way you see fit. Just be sure to keep it out of reach of children, as there will be some sharp edges.

Step 2: Take a knife, and whittle one end of each arm into sharp point.

Congratulations. You’ve just created your very own shiv. Perfect for recreating some of your favourite prison movie moments.

Catastrophe is inevitable because: It’s a flimsy weapon and once you bring stabbing into an equation, you really are going to want something sturdy. If nothing else, because you’re probably going to get stabbed back. This is another one that also carries serious jail time and is, I’d probably concede, morally wrong. I’m actually going to go right on ahead here and say that of all of the ideas on this list, this one is probably the worst. Also, if you’re using a knife to create the shiv, you’re absolutely wasting your time.

Potential fatalities: 7. You, plus a group of us who will die laughing at you for having the audacious stupidity to actually try it.

5. Impersonating Kanye West

There’s no way that the giant-skulled rap-warbler has never worn cinema 3D glasses as a fashion accessory. It’s simply impossible that it hasn’t happened.

Catastrophe is inevitable because: You end up looking like Kanye West, a man with a figuratively and literally giant head, who might be, even though nothing factually suggests it, a toilet nuisance. Once you’ve started to look like Kanye West, it’s only a matter of time before you start to act like him. Your relationship self-awareness will immediately strain and then shatter, the pieces frothing into nothing and disappearing forever. Then you’ll start singing like a robot.

Potential fatalities: 0. Consider this to be harmless, although be warned that you’re reaching Uwe Boll-ian levels of hatefulness if you do it.

6. Tomfoolery and deception

Have you ever watched a 2D film and wished that it was in 3D? No? What do you mean ‘no’?

Work with me, lie and say you have.

Yes? Well, how about pretending that it is by wearing your 3D glasses into the cinema for a non-3D film. This time, the pretending is not for your benefit. For this to work you need to pick a crowded showing and you’re going to have to make lots of ‘ooh’ and ‘aah’ noises. If you really want to sell it, reach out a little bit to try to touch the thing that isn’t actually coming out of the screen (although exercise caution. You don’t want to prod someone in the back of the head. It’s impolite and they might be carrying a homemade shiv).

Once you’ve been banned from your local multiplex, you could try the same trick but in more interesting places. How about a highbrow play? (And by highbrow, I specifically mean not panto.) You could even make some stickers saying ‘Now with added 3D’ and stick them on the posters outside the venue.

Be creative. Maybe try it at home while watching TV with your family. Try it at a pop concert or while watching a video on your phone in a bustling public area.

Catastrophe is inevitable because: You’re will either anger a mob or become the subject of their collective ridicule. Once people work out that you’re playing a prank on them, or punkulating them, as the kids say, they will either think that you’re very stupid and tut loudly, or they’ll become infuriated and tear you limb from limb.

Also, while you may not count this as a catastrophe, it’s worth noting that this one involves wasting huge amounts of your time with absolutely no benefit.

Potential fatalities: 1. You, and if not you, then your dignity. Seriously, you’re better than doing this.

7. Further tomfoolery and deception

For this one you will need a beloved pet dog and several months to train that dog to wear 3D glasses without causing a fuss. We do a similar thing in my house where we make Dr. Poodle Von Cuddlestein wear reindeer antlers all year just so he looks adorable on Christmas morning. Interestingly, if you look into his eyes for long enough you can see an aching for death. It’s mesmerising.

You need for your dog to be used to wearing the glasses by 1st July 2011. On this day, take him to see Transformers 3. Now, you are going to need to get your dog into the cinema. However, if you look closely at what this list is, it’s ‘alternative uses for 3D glasses’, not ‘how to sneak a pooch into a Cineworld’. You’re going to have to do some of the thinking for yourself. What, do you want me to tuck you in at night, read you a bedtime story and tenderly kiss you on the forehead too?

Anyway, you bring your dog into the cinema and have it wear the 3D glasses for the duration of Transformers 3. Then, at the end, you have to loudly ask what it thought of the film, wait a moment like you’re pretending to listen, and then agree that you thought it was shit as well.

Catastrophe is inevitable because: You have to watch Transformers 3.

Also, I can only imagine that it would be next to impossible to control a dog in a cinema. Too many smells, too many people, too many flashing images of colourful robots clumsily scrapping for no interesting reason. No matter how well you’ve trained it to wear its glasses, it’ll still more than likely go on a rampage through the multiplex, leaving a trail of aggravated anarchy as it does.

Top 10 3D games right now – plus what you need to play them

With Call of Duty: Black Ops built for 3D, the list of 3D-enabled games has reached a respectable number. So which ones are the best and what gear do you need to play them?

Avatar the movie hurled 3D into the public consciousness, but the true impact of 3D is being felt in gaming, where you’re not just watching a stereoscopic world, you’re totally immersed in it. Watching Avatar at the cinema was cool, but putting on the NVIDIA 3D glasses and firing up our ASUS 3D monitor to play Need for Speed: Shift in 3D was mind-blowing. It was the “wow” moment, the kind you get when a new, disruptive technology shows up to suddenly change the way things are done.

But although the technology pieces for 3D started appearing early in 2009, it’s only now that the content is finally catching up. The list of games that are not just “converted” to 3D but designed from the ground up to work with it has grown to the point where the investment in the requisite 3D hardware can be considered worthwhile.

Here is a list of the top 10 3D-enabled games and the gear you’ll need to play them. Be warned though – what comes through loud and clear from user feedback and our trawling of 3D gamer forums is that getting the games to work perfectly on your PC will require a bit of tweaking, and in many cases, you’ll have to turn the frame rate down and anti-aliasing off, as well as making any number of adjustments until your system can cope with the extra load of running in 3D.


This top 10 is based on own experiences with 3D games in the labs, general user feedback on the web and NVIDIA’s own ratings. NVIDIA is important here because it provides the only complete 3D solution for PCs, a kit called NVIDIA 3D Vision (explained at bottom of the story). It maintains a page in which it classifies the games by how well they exploit 3D, however not all our picks and user favourites agree with NVIDIA’s ratings. Many of the favourite 3D games don’t get the  “NVIDIA 3D Vision Ready” label that says they are perfect showcases of NVIDIA’s 3D kit. Thats’ because they have other 3D qualities that users love.


This is far and away the top 3D game right now because it works on all levels. BBC2 becomes much more visceral in 3D, creating an extraordinary sense of immersion in the battle. You can feel the action, experience the explosions, and your gun looks like a real 3D object. On a technical level, BB2 is also superior because of the attention to detail, the most obvious being the way it refocuses close objects such as your gun when you shift your gaze back from distant objects, overcoming the problem of having perfect depth of field in the distance but out-of-focus stuff close up. Like many of the 3D games, however, BBC2 in 3D may require you to tone the settings to play it smoothly.  Some BBC2 players also report they find it hard to adjust to 3D in gameplay.


This game is not in NVIDIA’s top list of new-generation 3D games, but the excellent reviews from users are just relentless and it can’t be anything but number two in our Top 10 list based purely on user praise. There is no doubt the three dimensional mystical landscapes and underworld are captivating, but our suspicion is that having a 3D babe as its major character is a significant driver of the praise from the young men who play this.


This is state-of-the-art 3D atmospherics. No game gives you a better sense of immersion into scary, claustrophobic interiors than Metro 2033, nor make your heart jump as much when a monster leaps out at you. If you just want to find out how 3D can envelop you, this is the game. It uses every technology at its disposal to generate realism, such as 3D, PhysX, Phong tessellation and direct compute. But some things have to give, and you may have to turn down the graphics settings to enjoy it in 3D


Batman just does 3D superbly. It’s often the game used by vendors selling 3D hardware so that gives you an idea of how polished it is in three dimensions. It’s a cliché, but people and objects in it just seem to leap out of the screen.

5. MAFIA 2

What do you need to get right for a game about the Mafia? The suits! These Italian-American guys like to dress in expensive suits, so Mafia II uses a special “Apex Clothing Module” from the PhysX Developer Toolset to bring you the Mafiosi’s fabrics in astonishing realistic fabric. The theme carries through to explosions as well, as things blow up with super realism, each bit of shrapnel behaving as you’d expect it in a real explosion – unpredictably. In all, a graphical stunner.


This game is a standout for its amazingly realistic landscape, particularly the way the water and light behave. That’s because it’s the first game to use NVIDIA’s CUDA technology to the fullest, particularly when rendering water – where you see incredibly realistic micro ripples and fine grained reflections. CUDA is also used for creating high quality depth of field effects. Just Cause 2 is so nice you don’t want to ruin it with the need to kill and blow up things. As one forum user says: “Sometimes I prefer just driving around watching the scenery, rather than blowing up everything.”


Racing simulations is the most competitive 3D category of all – probably because racing games benefit more from 3D than any others. Once you’ve raced in 3D you will never go back to 2D, and it’s often said that many players find their times dramatically improve when moving to 3D because the environment is much closer to the real one they experience in their cars. There are many standout titles in this. Need for Need for Speed – Shift, Flatout and Burnout Paradise are consistently praised – we couldn’t really separate them but since we’ve actually played Need for Speed and been blown away by it (the “wow” moment) it gets the gong.


One of the next-generation 3D games with the works. Definitely one of NVIDIA’s 3D Vision showcase games that feature not just 3D but DirectX 11 support, hardware tesselation, computer shader and so on . In short, you go to a totally immersive planet with amazing landscapes in which you fight to take control of the Thermal Energy that drives weapons.


Regardless of the movie, AVATAR the game is actually great in 3D, and may gamers still rate it as their favourite. Enough said. Watch the movie, enjoy the game.


The first Call of Duty game to be built for three dimensions. Black Ops in 3D probably deserves to be higher up this list, but right now it’s too new, too untested for us to say it’s totally up there. From what we’ve seen and early users are saying, it’s incredibly promising. Like in Battlefield Bad Company 2, the depth of field makes you feel as if you’re there, in battle. The lead cinematics animator on Call of Duty, Adam Rosas, reportedly said “ We used 3D to give you better transitions and to work certain elements into the game. If you want an element of surprise, you can use this 3D technology to actually surprise a player, rather than just putting a flash on the screen. You can really implement 3D so that your peripheral vision will catch something and you’ll look over there, where you can fully reveal what you want them to see. So 3D can be used to draw the player where the action is within a story. It’s even a better visual cue than lighting, which games have used to send players in a certain direction.”

The Best to Places to Put a Humidifier

If your home’s air tends to become dry during the summer or winter months, a humidifier is an affordable solution to restore moisture to the air. The placement of the humidifier depends on the use of the rooms in your home, as the bedroom and living room are common living spaces that benefit the most from moisture replenishment.

  • A lack of moisture in the air while you sleep increases the likelihood of nasal congestion, which causes coughing and interrupted sleep. The bedroom should be humid to improve your ability to breathe steadily while sleeping for a good night’s rest.

Living Room

  • The living room is often one of the most frequently used rooms of the home besides the bedroom, and it benefits from a warm- or cool-mist humidifier maintains your furniture and hardwood floors by providing moisture. According to Real Simple, the humidifier provides moisture to reduce wood cracking.

Child’s Room

  • Just as you benefit from a humidifier, a cool-mist humidifier moisturizes your child’s skin and decreases congestion caused by sinus problems. Cool-mist humidifiers are suggested over warm-mist, as the risk of injury is high if a child accidentally tips over the warm-mist humidifier.

Flat surfaces

  • Set the humidifier on a flat surface to avoid water leakage. The surface should be hard and not upholstered, as upholstered surfaces absorb moisture, allowing bacteria to grow in the fabric. Keep warm-mist humidifier at least two to three feet away from you to avoid accidental burns. For do-it-yourself humidifiers, place a pot full of tap water on top of a steam radiator to add moisture to the air.

Before buying a humidifier, you need to know this.

When winter comes around, the lack of natural humidity causes the air to dry out. The lack of moisture in the air is evident in the form of static electricity, dry skin, more dust and an increase in illnesses.

If the lack of humidity in your house is making your skin, throat or nasal passages dry, it’ s time to look in to buying the best humidifier. But which type of humidifier is the best? We break it down below.

The Five Types of Humidifiers:

Ultrasonic Humidifiers:
They produce a warm or cool mist by using a metal diaphragm vibrating at high-frequency. The sound vibrations propel moisture into the air. The water molecules that are produced are extremely small, about one micron in diameter. The mist is almost immediately absorbed into the air. Because this type of humidifier does not use a fan, it is very quiet when operating. Ultrasonic humidifiers typically do not use a filter.

SainSonic LM-168 500ML Ultrasonic LED Air Humidifier Aroma Diffuser

Unlike the humidifiers that boil water, the water droplets that are produced by an ultrasonic humidifier contain any impurities that are in the water tank which include minerals contained in hard water. If you use tap water in an ultrasonic humidifier it will produce a white dust on which can settle on nearby objects and furniture. If you use distilled water white dust is not produced. If you choose to use tap water you can use  our FLTDC Humidifier Decalcification Filter to prevent white dust from being created.

Additionally if you tank is not clean, pathogens growing in the reservoir can be expelled into the air. Guardian Technologies Pureguardian™ Ultrasonic humidifiers utilize Silver Clean™ Technology to fight the growth of mold and mildew on the surface of the water tank.


These humidifiers tend to be the least expensive. They work by boiling water which produces steam. The steam is then cooled slightly before being released in to the air. Warm-mist tabletop units are quieter than the evaporative type of humidifiers, but they are also more costly to operate.

Warm-mist humidifiers can also raise the air temperature in a room which is nice in the winter but not so wonderful if you live in a warm location. If you have small children, using a warm-mist humidifier is not recommended because the heated water can cause accidental scalding. They are also not recommended if anyone in your house suffers from asthma due to the warm mist causing irritation to the airways.

A vaporizer boils water which then releases steam and moisture into the air. A medicated inhalant can also be added to the vaporizer to help diminish coughing spells. Vaporizers tend to be healthier to use than cool mist humidifiers because the steam is less likely to deliver impurities or microorganisms from the water in the holding tank. Boiling water requires a lot more energy than other methods.


Impeller types of humidifiers, also called cool mist humidifiers, use a spinning disk to deliver water into a diffuser which then breaks the water into droplets that float into the air. Along with the water, they can also send microorganisms and dissolved minerals into the air which can settle as white dust onto surrounding household items. To prevent this it’ s recommended to fill them with distilled water which adds substantially to the cost of operating the humidifier.

Evaporative humidifiers operate by soaking water up into a wick and expelling the moisture out with a fan. Large console humidifier models all make up this type. Small evaporative humidifiers are inexpensive and their filters assist in keeping microorganisms and minerals in the water from being sent into the air. However, it’ s very important to clean them regularly and have their filters changed when recommended. The evaporative humidifier is the most common one on the market. They are also called cool mist or wick humidifiers.

Evaporative humidifiers have 3 basic parts, the wick, the water reservoir and the fan. The wick is a filter that soaks up water from the reservoir and gives it a larger surface area for it to evaporate from. The fan is next to the wick and blows air onto it to help with the water evaporation.

The water evaporates based on the relative humidity of the room. A room with low humidity will allow water to evaporate more quickly compared to a room which has high humidity. Therefore, this type of humidifier regulates itself. As the humidity of the room goes up, the water vapor goes down.

The wicks or filters become moldy if they are not dried out between reservoir fillings. They also can become filled with mineral deposits over time. The filters need regular rinsing or replacement. If this isn’ t done, air cannot pass through the wick and the humidifier stops humidifying the area. You’ ll know the humidifier is not operating properly by the water remaining at the same level in the tank.

Humidifiers: Air moisture eases skin, breathing symptoms

Humidifiers can ease problems caused by dry air. But they need regular maintenance. Here are tips to ensure your humidifier doesn’t become a household health hazard.

Dry sinuses, bloody noses and cracked lips — humidifiers can help soothe these familiar problems caused by dry indoor air. Humidifiers can also help ease symptoms of a cold or another respiratory condition.

But be cautious: Although useful, humidifiers can actually make you sick if they aren’t maintained properly or if humidity levels stay too high. If you use humidifiers, be sure to monitor humidity levels and keep your humidifier clean. Dirty humidifiers can breed mold or bacteria. If you have allergies or asthma, talk to your doctor before using a humidifier.

What are humidifiers?

Humidifiers are devices that emit water vapor or steam to increase moisture levels in the air (humidity). There are several types:

  • Central humidifiers are built into home heating and air conditioning systems and are designed to humidify the whole house.
  • Ultrasonic humidifiers produce a cool mist with ultrasonic vibration.
  • Impeller humidifiers produce a cool mist with a rotating disk.
  • Evaporators use a fan to blow air through a wet wick, filter or belt.
  • Steam vaporizers use electricity to create steam that cools before leaving the machine. Avoid this type of humidifier if you have children; hot water inside this type of humidifier may cause burns if spilled.

Ideal humidity levels

Humidity is the amount of water vapor in the air. The amount of humidity varies depending on the season, weather and where you live. Generally, humidity levels are higher in the summer and lower during winter months. Ideally, humidity in your home should be between 30 and 50 percent. Humidity that’s too low or too high can cause problems.

  • Low humidity can cause dry skin, irritate your nasal passages and throat, and make your eyes itchy.
  • High humidity can make your home feel stuffy and can cause condensation on walls, floors and other surfaces that triggers the growth of harmful bacteria, dust mites and molds. These allergens can cause respiratory problems and trigger allergy and asthma flare-ups.

How to measure humidity

The best way to test humidity levels in your house is with a hygrometer. This device, which looks like a thermometer, measures the amount of moisture in the air. Hygrometers can be purchased at hardware stores and department stores. When buying a humidifier, consider purchasing one with a built-in hygrometer (humidistat) that maintains humidity within a healthy range.

Humidifiers, asthma and allergies

If you or your child has asthma or allergies, talk to your doctor before using a humidifier. Increased humidity may ease breathing in children and adults who have asthma or allergies, especially during a respiratory infection such as a cold. But dirty mist or increased growth of allergens caused by high humidity can trigger or worsen asthma and allergy symptoms.

When the air’s too damp: Dehumidifiers and air conditioners

Just as air that’s dry can be a problem, so can air that’s too moist. When humidity gets too high — common during summer months — it’s a good idea to take steps to reduce indoor moisture. There are two ways to reduce humidity:

  • Use an air conditioner. Central or window-mounted air conditioning units dry the air, keeping indoor humidity at a comfortable and healthy level.
  • Use a dehumidifier. These devices collect excess moisture from the air, lowering humidity levels. Dehumidifiers work like air conditioners, without the “cooling” effect. They’re often used to help dry out damp basements.

Keep it clean: Dirty humidifiers and health problems

Dirty reservoirs and filters in humidifiers can quickly breed bacteria and mold. Dirty humidifiers can be especially problematic for people with asthma and allergies, but even in healthy people humidifiers have the potential to trigger flu-like symptoms or even lung infections when the contaminated mist or steam is released into the air. Steam vaporizers or evaporators may be less likely to release airborne allergens than may cool-mist humidifiers.

Tips for keeping your humidifier clean

To keep humidifiers free of harmful mold, fungi and bacteria, follow the guidelines recommended by the manufacturer. These tips for portable humidifiers also can help:

  • Use distilled or demineralized water. Tap water contains minerals that can create deposits inside your humidifier that promote bacterial growth. And, when released into the air, these minerals often appear as white dust on your furniture. You may also breathe in some minerals that are dispersed into the air. Distilled or demineralized water has a much lower mineral content compared with tap water. In addition, use demineralization cartridges or filters if recommended by the manufacturer.
  • Change humidifier water often. Don’t allow film or deposits to develop inside your humidifiers. Empty the tanks, dry the inside surfaces and refill with clean water every day if possible, especially if using cool mist or ultrasonic humidifiers. Unplug the unit first.
  • Clean humidifiers every three days. Unplug the humidifier before you clean it. Remove any mineral deposits or film from the tank or other parts of the humidifier with a 3 percent hydrogen peroxide solution, which is available at pharmacies. Some manufacturers recommend using chlorine bleach or other disinfectants.
  • Always rinse the tank after cleaning to keep harmful chemicals from becoming airborne — and then inhaled.
  • Change humidifier filters regularly. If the humidifier has a filter, change it at least as often as the manufacturer recommends — and more often if it’s dirty. Also regularly change the filter in your central air conditioning and heating system.
  • Keep the area around humidifiers dry. If the area around a humidifier becomes damp or wet — including windows, carpeting, drapes or tablecloths — turn the humidifier down or reduce how frequently you use it.
  • Prepare humidifiers for storage. Drain and clean humidifiers before storing them. And then clean them again when you take them out of storage for use. Throw away all used cartridges, cassettes or filters.
  • Follow instructions for central humidifiers. If you have a humidifier built into your central heating and cooling system, read the instruction manual or ask your heating and cooling specialist about proper maintenance.
  • Consider replacing old humidifiers. Over time, humidifiers can build up deposits that are difficult or impossible to remove and encourage growth of bacteria.
