This functional little humidifier makes maintaining proper humidity levels easier than ever. Our humidifiers work by adding invisible moisture to your environment by moving dry air through a saturated wick. Maintaining proper humidity levels between 30-50% in your home/office/workplace has been scientifically proven to help prevent the flu and allergies. Proper humidity hydrates your skin, alleviates dry eyes, scratchy throats and can reduce snoring. With a doctor's approval increased humidity can reduce asthma and allergy symptoms. It also protects fine furniture, musical instruments, collectibles and wood floors. Proper humidity makes you feel warmer allowing you to lower your thermostat setting which will save money.

Rated 4.2 out of 5 by 75 reviewers.
Rated 5.0 out of 5.0 by Digital controls keep exact humidity level This humidifier keeps the humidity at the exact level you set it. I have had other humidifiers in the past that would not turn on or off unless the humidity level changed drastically. Love it! Getting ready to purchase another one. December 11, 2013
Rated 5.0 out of 5.0 by Works Well and Lasts a Long Time This is my fourth Winter with my EssickAir(AirCare)MA0800. It easily pumps 8 gallons of water into the air every day on High speed. Yes, the Filter Wicks last about one month but that's because of all the dissolved minerals in my water. Even on Cold days when the heat runs alot, it will keep the humidity around 40%. I bought a second water bottle to allow me to change them out easily. Someone complained that it might put 8 gallons out a day but the bottle only hold 2 and a half. Well an 8 gallon bottle would weigh about 66 pounds and would be very awkward to load and unload into the unit. I fill the humidifier bottle and use a water jug to fill the basin portion each time and that gives almost 4 gallons of run time. I have found it to be well worth my time and money. November 20, 2015
Rated 5.0 out of 5.0 by VERY GOOD PRODUCT I have had my unit for 2 years now and keep it running all year round. It still works perfectly. I love the automatic feature and the ability to set the humidity. I agree with other reviews that the square footage is off. It does not work well with a 1700 square foot house. I have an additional one in my bedroom. The filters can be costly but I found that if you rinse them out carefully and dry them in the oven at 200 degrees I can keep a filter much longer. I have had several units and this is the best so far. If this one is still available when I need a new one I will buy this again. November 6, 2013
Rated 5.0 out of 5.0 by Very Good Purchase I found the unit easy to use right out of the box. It seems adequate for my large bedroom and runs quietly. I have to refill it about once a day and run the fan on second speed. I'm happy with its performance and quick service by HomeDepot. November 13, 2015
Rated 5.0 out of 5.0 by works very very well The unit was smaller in size then what I expected but it works much better then the larger one that it replaced. My wife and I are very pleased with how it is working. I would highly recamend to anyone. March 24, 2015
Rated 5.0 out of 5.0 by Best purchase ever I have owned other humidifiers before, but this is the best. Thought is was a little expensive. It's worth every penny. Almost silent. Goes on and off by itself. I would buy it again. March 10, 2015
Rated 3.0 out of 5.0 by Decent price, but has a few flaws. I bought one of these on a black Friday sale but am hesitant to use it as I noticed a major issue upon unboxing - one can't see into the reservoir to see if it needs cleaning. I have another evaporative humidifier and can list the pros of why I bought it below and cons of my unboxing and experience with my other unit below. Pros: Low initial cost Won't over humidify Auto low water shutoff Medium size footprint Quiet enough if you only need to humidify 850 sq ft Huge (sq ft) coverage Cons: Cools the air - acts like a swamp cooler which can make it harder to keep you house at temperature. No cap to unscrew - Can't see into the reservoir to determine if it needs cleaning! Small Reservoir - must fill 3 times a day on max setting!! Costly filters - need to be changed every 2 weeks to 2 months depending on how hard your water is / how much maintenance you are willing to put into them - new filters are about $15 a pop. Loudness - max setting is loud (as it always is for evaporative humidifiers) Alternatives: I have a Honeywell evaporate humidifier that is essentially the same but uses two 3 gallon tanks (6 gallons) that easily stand upright while filling. It uses 3 smaller filters and doesn't have an auto shutoff when the reservoir dries out, but I'd still recommend it over this one due to it's ease of cleaning, and filling (when one tank runs out you still have a back up tank, so you just keep alternating filling empty tanks). My parents have an upright wooden box style humidifiers that you use a pitcher to pour water, and while a bit more difficult to fill requires the least amount of maintenance. It works by rotating plastic netting like a conveyor belt though the reservoir and over the fan that blows up the moisture. As far as portable evaporative systems, this is what I'd buy if I could afford it. Overall, if you have hard water, evaporative style of humidifiers are going to require a lot of maintenance and/or new filters and thus is not recommended. Ultrasonic humidifiers also act like swamp coolers, and it is difficult (but not impossible) to find ones that can cover this kind of area, and comparative coverage is much more costly. They re the quietest of all humidifiers and maintenance is minimal, but they do leave behind a white powder of the precipitated impurities in the water. I haven't tried one specifically, but hear the white powder is particularly bad if you have hard water and thus isn't recommended. Nonetheless, for those of us with hard water I can't imagine they are much more work than evaporative humidifiers. Thus, if you can find comparable coverage and can afford the markup, it might be better to go with one of these type of systems. Steam based humidifiers solve the swamp cooler effect, but all portable units I've found don't cover nearly the same amount of area as this unit however one might consider just buying 3 separate ones, but I'm guessing it's not cost effective. Further, often people complain about bacterial mold buildup with these units as they tend to warm their reservoirs as well. There are 2 main types of portable steam humidifiers. filamentous and conductive. Filamentous work much like a toaster oven, but the filaments are often covered to make it easier to clean the enviable lime scale build up. Indeed, just spraying a little vinegar on the interior pieces of the apparatus makes for easy clean-up / maintenance. Conductive steam humidifiers uses the waters own conductivity and essentially electrifies the water, the waters own resistance provides the friction for heat generation, thus it is more efficient than the filament - in fact, it's probably the best way to electrically generate steam. The caveat here is that distilled water wont conduct, thus hard water is actually a plus with conductivity based steam generation. In fact, if you have hard water either type of steam humidification will provide you with the lowest amount of maintenance possible. The electrode based system however is more difficult to clean, and new electrodes are sometimes sold as a disposable component. All in all, portable humidifiers require a lot of attention. Ideally there would be some sort of direct-line / portable system hybrid that could tap into your filtered drinking water supply and gas stove, but no such monster exists. Ultrasonic wall mounted direct-line units made for offices do exist, but they are hard to find (fortunately Home Depot sells one), that are extremely low maintenance, but they cost much more. However, as I hate filling reservoirs, I'll probably try the Home Depot unit (steam based ones are 3x the cost). Steam and evaporative wall units don't seem to exist (though I didn't look hard for evaporative ones) as a complete system. But are available for those of you with heating duct work (HVAC), and I'd what I'd recommend getting if you do already have duct work (for those with hard water, you want a conductivity based system as it will be the lowest maintenance). There are often modification kits (like the Aprilaire 865) for those without duct work, but I haven't found any that don't require cutting large holes in my house. I've obviously waisted a lot of time on this - hope it helps someone else. December 4, 2013
Rated 5.0 out of 5.0 by Best Humidifier I've ever owned. I've only had it a month and its been a mild winter so far, but this product has worked flawlessly. It maintains the humidity and only runs when needed. The low setting is quiet and doesn't disturb our sleep. No more dry skin and dried out sinuses. I hope it last for years. January 7, 2012
