Keeping Indoor Humidity Levels Between 40-60% Has Many Benefits
Helps temporarily relieve congestion and cough
Maintaining an indoor humidity level between 40-60% can reduce the survival of flu viruses on surfaces and in the air.*
*Studies have shown that keeping indoor air at an RH level of 40-60% reduces survival of flu viruses on surfaces and in the air compared to lower RH levels.
Helps Protect Furniture
Low humidity causes wood to lose moisture and shrink. Extreme changes can causes warping and cracking.
Helps You Breathe Better and Sleep More Comfortably
Comfortable humidity helps keep throat and nasal passages hydrated.
Helps Reduce Static Electricity
Returning moisture to dry air helps reduce static shocks.
How the Technology Works
The humidifier's scientifically proven process uses a patented Ultra-Violet light technology to kill up to 99.9% of bacteria, mold, fungus, and virus in the unit's water. This provides the assurance that the moisture the humidifier emits is virtually free of germs.
1. Untreated tap water flows from the water tank into the UV water path where it is exposed to ultra-violet light which kills mold, bacteria, fungus and virus.
2. The sanitized water enters the base where it is absorbed by the wicking filter.
3. Dry indoor air is drawn through the filter absorbing the moisture.
4. Up to 99.9% Germ Free moisture is emitted into the air as a fine visible mist.
Essential oils should not be used in the tank of any humidifier – the oils can damage the humidifier and void the warranty. Only water should be put in the tank of the humidifier.

Up until that time I had been using a Vick's Cool Mist humidifier. I didn't love that humidifier because it needed regular cleaning/sanitization and because it created white dust (small mineral dust from the minerals in the water) in the room where it was used. It was hard to clean due to several nooks & crannies. In the process of cleaning that Vick's humidifier, I got some water in the motor and it became quite noisy, thus prompting its replacement.
Two years later, I find that I need to clean this Honeywell unit a lot less than the Vick's unit. That's good. I also need to dust a lot less, also good. One downside is that the performance of the unit can really decline as the filter ages. Sometimes the dropoff is quite steep. Maybe the filter lasts 6 weeks, maybe 2, maybe longer if I start buying distilled water for it or if I start cleaning it regularly (but what's the point of spending time and effort on tending to the filter if I'm using the filter to save time and effort?). The second downside is the cost. The unit is now close to $70 and the filters are over $15. The Vick's Cool Mist humidifier is only $36. Buying a new Vick's unit every 3 months is starting to seem like the logical way to go.
Update 9/6/18 - This summer the filters are selling for less than $7, and even cheaper with Subscribe and Save. If you do choose to buy this humidifier, you may be well served to stock up on filters during the summer.
Update 12/10/18 - At this moment, the regular price of the filters on Amazon is $22.93. Unbelievable!
• Can be cleaned thoroughly. The bottom tray and tank can be placed in the dishwasher or can easily be scrubbed by hand because the hole in the tank is large enough to fit an arm through. I clean it in the dishwasher without detergent and turn off high heat/sanitize and heated dry to avoid melting the plastic. The large opening in the tank also makes it pretty easy to dry the inside of the tank to deter mold growth. However, there's one spot inside the tank that's not easy to scrub. I has a weird shape where the handle is located. I haven't had mold grow in that spot, but I consider this a design flaw. I recommend cleaning once a week or the tray will get slimy. I've had this happen when I missed a week.
• I do recommend cleaning the wick along with the tray, tank, and lid weekly, and allowing the wick to dry each day because it definitely can grow mold. My first one did. Once a week, I soak the wick in vinegar, then rinse in water. Every day I remove and wipe out the tank and allow the unit to run until the wick is dry. I haven't had any issue with mold since I started doing this that first year.
• You have to buy wicks. Cleaning them does extend the life of them, but they don't last forever. I'd say mine last a few months before they get hard and begin falling apart.
• The tank lid is NOT easy to clean, and I don't put it in the dishwasher or soak in vinegar because I'm afraid of damaging the rubber seal. I clean with soapy water, a toothbrush, and Q-tips every week. It gets slimy/moldy if I don't. (I also find it difficult to get the lid screwed on tight enough to prevent leaking and have to try several times most times I fill it.)
• As one commenter stated, the fan blades aren't easy to get to to wipe off dust. I've found this issue with every fan I own. I use compressed air cans remove the dust from the blades. This works very well on this unit unlike the tower fan I own. (That commenter also stated that there was mold on their blades, but that's never happened to mine. I only run it at night though, so perhaps if run 24/7?)
• It definitely humidifies my large master bedroom and I notice a huge difference in my throat and sinuses when I use it. However, it's difficult to control the level of humidity. Even on low it seems to cause condensation on the windows. My old unit had a setting for humidity level, but this just has high, medium, and low settings.
• This is a difficult one because people vary in their noise tolerance. The fan does make noise even on low. I personally like that because it's a mellow, low-frequency white noise that helps drown out sounds and helps me sleep.
• As I stated, I've had it for over three years and it still works great. I use it all night during autumn, winter, and spring.
• The UV light lasted about three years. I recall it working last winter, but I don't think it is now. However, I don't think it really made any difference anyway and it actually damaged the plastic tray around it in the same way constant sun damages hard plastic. This hasn't affected the way the unit works, but I can scrape plastic off with my nail there whick causes me some concern.
• My opinion is that this thing is big and ugly. It takes up quite a bit of space.
Would I recommend it? Yes if you want something that lasts, that you can clean, that works well and if you're willing to deal with the cleaning and wick replacement. Not if you're looking for something pretty, compact, and/or silent (I think it's pretty quiet, but not silent).

The humidifier was used in a ~130 square foot bedroom during the winter with forced air heating. It was able to effectively raise relative humidity from 20-25% to 40-50%, depending on the speed setting used. We typically had it on the lowest setting for gentle white noise at night; humidity levels averaged in the high thirties to low forties.
We live in a hard water area and initially contemplated using distilled water, but at a cost of about $1/gallon and the use of about one gallon per night for the bedroom would quickly exceed the cost of a couple filters. We used tap water and the filter eventually developed a light brown, crusty appearance along its edges, even when flipped daily with each reservoir refilling. This was due to iron and hard water, not due to mould. To prolong filter life, we used two filters during the season on a rotating basis. One in use while the other soaked in a strong white vinegar & water solution until needed. The vinegar solution was effective at removing the hard deposits, but was never able to quite restore the filter to 'like new' appearance (we didn’t try bleach, which might also be effective for those complaining of mould). But this pretty much maintained effectiveness. IIRC, we rotated the filters probably every couple weeks. Eventually the filters lost some structure and were replaced for this winter, but two for a full winter season seemed fairly reasonable. The humidifier was used every night and rarely sat idle longer than 12 hours, therefore can't comment on how the filter would handle being left in a wet but unused state for prolonged periods, which probably isn't ideal. We felt the lack of auto shutoff was not a major problem because it’s effectively just a fan inside an enclosure (though there’s also the UV light, which apparently has a finite lifespan).
We did not have any problems with the glued seams of the replacement filters breaking, though we were careful not to put much stress on this area when in the vinegar soak, or while handling during the rinse process. That said, compared to the original filter included with the humidifier, these seemed to be slightly thinner walled.
Overall, it works for us and we continue to use it this winter season.
Remember that your results may vary. It depends on many factors... including how many showers you take per day and if you cook at home!
Otherwise, fast and efficient at adding moisture to the air. It's been a godsend in the winter season. Highly recommend, although I'd look into buying a thicker 3rd party filter that lasts a bit longer.
