Honeywell Cool Moisture Humidifier, Medium Room, 1 Gallon Tank, White – Invisible Moisture Humidifier for Baby, Kids, Adult Bedrooms – Quiet and Easy to Clean with UV Technology for Everyday Comfort

Easy to use and fill, evaporative humidifier (no white “dust”). Get one of the silver ion capsules to put in the tank and it’s super easy to clean. Fan makes almost no sound on low. A very soothing hum on medium. I flip the filter upside down every week to keep it moist on both ends. Raised humidity ~5% in a smaller family room on medium setting.

The media could not be loaded. I bought this on Amazon in February 2019 and it is now February 2024 and I felt the need to write a review (I almost never write reviews, but I have a useful tip that I wanted to share).Like a lot of people, I needed a humidifier to help with sinus issues b/c the winters are so dry. I've had other humidifiers with the cool mist, and the white dust was a major issue (the amount of water I go through with my humidifiers made purchasing distilled water unrealistic). This humidifier completely solved the white dust problem while using my tap water. The fan sound went on low is quiet enough that when I have it in my living room, it doesn't bother me, and if you are a white-noise-while-you-sleep kind of person you would probably be perfectly happy with it on a higher setting as well. The bubbling of the water emptying the tank into the tray can be distracting when I have people over and they hear it. I rarely notice it, but if you plan to have it in a bedroom and a light sleeper, that's something to keep in mind (I also have Honeywell's other evaporative humidifer that does not have a separate tank and so does not have that issue and that is in my bedroom - I find that one to be less convenient to fill, though).The plain white filters work fine - how long each will last depends on how hard your water is. I will note, I forgot to purchase refills once and was able to use one of the washable/reusable ones for another humidifier I have but that humidifier and those wicks don't seem to still be available on Amazon but it seems any humidifier that uses those cylindrical filters uses the same size filter.This year (the 5 year mark) when I first got it out at the beginning of the season the gasket was leaking a little bit when I refilled the tank since it's rubber and as it ages it has become stiff and brittle. Multiple reviewers have mentioned this and have expressed frustration that you can't seem to replace that one tiny rubber bit. I was getting ready to consider purchasing another one but as the only thing that seem to be wrong, was that one gasket I felt uncomfortable with throwing out the one I purchased five years ago. I decided to give something random a try to see if it would work first... I am pleased to announce that it absolutely worked better than I imagined!I do hope that Honeywell does offer the option to purchase a replacement water bottle cap (or at least the gasket) in the future, but in the meantime, if you don't want to get rid of the entire unit because it's working fine and you need to replace that one gasket there are other humidifiers out there with caps that sell replacement caps. The other caps are significantly smaller and the gasket is also a bit smaller than the cap and gasket on this Honeywell humidifier, however, the gasket doesn't actually need to be as large as the original one it seems!I purchased a replacement cap that appeared to have the same spring/rubber gasket mechanism to see if I could cannibalize the gasket from the other cap (I purchased this one that is for a slew of models including Emerson, MoistAir, Kenmore, etc: https://www.amazon.com/gp/product/B082K4X4SQ/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1). I was able to pop the rubber bit off of the small cap and use that in place of the rotting one on my Honeywell and I no longer have to be extra cautious when flipping the tank over to place back onto the unit!!Hopefully, Honeywell offers replacement caps in the future so people don't need to purchase a whole new unit for one tiny, very replaceable part!

My main concern was the white dust that quickly coated so many things in my bedroom. Articles say its "harmless" but think about it.Then I learned about evaporative humidifiers. Sure you need to purchase filters, but it became worth it to me.It has been 10 days now and no white dust to be found. Amazing.I wondered if the Low setting, which is beautifully silent, would give enough moisture in the night. I live in Arizona and always need it. It almost always reaches to 50 - 51% each night on Low and that's the max for me. It would be so nice to have a thermostat as my previous mist humidifier did, which would turn off at a set percent. That means I have to check the humidity level in my room when I wake in the night and turn off if necessary. There may be one out there for a larger area, but not for a small room like mine.All that being said I absolutely LOVE it!

I like this device and it works pretty good for putting the moisture back in the air in the natural way - via evaporation - during winter heating season. During this time the furnace is doing its job by taking the moisture out of the air and since all the windows are closed most of the time (as you don't want to take in a lot of cold air and make your house cold) the external air intake is not enough to replenish the moisture even in such a "wet" place like here in Seattle. Your skin goes dry, eyes itch and nasal passages feel uncomfortable. With dry air you are more prone to get an airborne infection. Finally when we installed a smart thermostat that also shows the humidity in the air and it showed unhealthy 30% humidity I figured out that humidifier is an important "life support" system you need to have in your house when its cycling the air inside during the winter.The device is bigger than ultrasonic humidifiers we had in the past but for a good reason - since it relies on natural way of water evaporation and you need larger surface contact area with the air to make it work. Ultrasonic humidifiers work in another way - they force the water vapor in the air by exciting the water with ultrasonic membrane so it bursts in bubbles which break and release mist in the air. The assumption here is that tiny droplets of mist have much larger contact with air (this is what the big filter is for in this device) and evaporate quickly in dry air. But the problem is that some of them don't - and those land down on the floor near the ultrasonic humidifier making it wet and leaving mineral residue from the water droplets around the device. Another problem with ultrasonic humidifiers - they put equal amount of moisture in the air regardless how humid the air is. If the air is dry - it pick more moisture from the mist, less dry air - takes less leaving more to land back on your floor around the device.This device is free from those pitfalls of ultrasonic humidifiers. It evaporates the water in the air in the natural way, like everything else exchange the moisture around you. It just speeds the process in two ways: (1) by increasing the contact area with the air with large filter made of strings of porous material that pick the water from the bottom tray using capillary action; (2) by increasing the volume of dry air the contacts with the filter by blowing through with the fan. Because of this natural process the amount of moisture it puts in the air depends on how dry you air is. It never puts more moisture in the air that the air cannot take, so the floor around the device is never wet and no mineral residue.The device is very simple - the bottom tray which feeds the water to the filter, the filter that evaporates the water and the water tank that feeds the water to the tray through the valve and main body that houses 3 speed fan and UV light. I thought the device will be warming water so it is easier to evaporate, but it does not. Because of this simple design the cleaning is easy.Now about the filter - as you can see it is most essential part of this device. To make it last longer you need to understand how it works. It pulls the air from the tray using capillary action. When filter ages, is capillary get clogged with minerals from the water. So it starts drawing less water. So the more mineralized water you have the less filter life you are going to have. You can try using filtered water - but I am not sure how economical it would be - it consumes a lot of water and filters also cost money. So maybe it will be cheaper to buy a new humidifier filter than buy water filters more frequently. Another factor is fan speed - it is better to opt for slower speed with aged filter because it won't be able to draw as much water and will dry out and minerals in it will solidify aging it more faster. I noticed that even with new filter and top fan speed the topmost part of the filter gets dry after a couple of hours of runtime. So avoid running at top speed - and it produces definitely audible noise in this mode.As for the noise - I find that at top speed it's pretty noisy - you can definitely hear it running if you are in the same room. Middle speed (recommended by the manufacturer as a regular operating speed) is audible if you are few feet away from the device. Low speed is barely audible.I am skeptical about UV light feature if it is useful at all. Think about it - it is supposed to kill germs in the water that flows from the tank to the filter. But that water comes right from the tap (the same water that you drink) and the tank is refilled every day. But the part where there are much more germs - the filter - is not getting any UV light and is in constant contact with external air that brings new microbes all the time. So when the UV light goes out, I do not think I want to spend money on replacing it.Last point - this humidifier is listed as 'single room' humidifier but if you place it in the room where you have air return it can affect the air humidity in the whole house. Humidifier was off for the night today and the thermostat in the other room was showing 43% humidity. Turning the humidifier on with middle speed (it is located close to furnace air return) and turning on the furnace fan after that for a while brought the humidity reading in the other room up to 48% in about an hour.Hope this review is helpful. Thanks.
