Honeywell HUL520W MistMate Ultrasonic Cool Mist Humidifier, White – Cool Mist Humidifier for Bedroom, Home or Office

This thing really puts out a good blast when on full. I usually turn it down after a few minutes. Not made for a whole house, but does well for a room at a time, or a section of a big room.Easy to use, easy to fill.Compact and looks nice. Some have bigger tanks but this one is good enough for 5 to 10 hours depending on how high you adjust the output. We usually only run it for 2 or 3.Very satisfied !

JAN 2015: Works perfectly! We've set ours at about half for several nights, all night long and the tank was still 1/4 to 1/2 full. We ran it on full blast for 7 hours at one point, and there was still at least 1/4 tank left. It makes a quiet hum, but doesn't affect your sleep.It's a nice compact size, but not tiny. You can see the steam that comes out- we like that. If you set it on a carpet floor, the carpet will be slightly damp there after awhile. Not damaging, but even setting it on a stool corrects that if it bothers you. And make sure it's not pointed directly at something, as that object will end up quite damp. For $27 and no filters, ya can't beat it!UPDATE JANUARY 2017:2 years and still going! I'm amazed. After about a year, it would make this awful noise when you first turned it on and sometimes it wouldn't come on. I thought it was broken, but we just left it on and in a minute or two it kicked on. The awful noise would disappear after about 20 seconds. It still does that sometimes. We do not clean it either- we use it all winter, store it all summer-- no filters to deal with. I am really impressed with this little guy!UPDATE JANUARY 2018:Still going strong! Love this little guy. Just yesterday soaked it in white vinegar for the day, rinsed and scrubbed the hard water deposits (I've done this maybe 3 times total in the last 3 years) It hasn't made the loud noise for about 9 months - no filter, no problem - absolutely love it!

It works well and is quiet, but it leaves a puddle underneath the unit. I would not set this on a wood floor or any wood furniture. I noticed this initially, but I was using it a lot, and hey, it's water! So I just wiped up the puddle. But the weather warmed up, and I stopped using my heater and left the humidifier turned off. I came back today and found almost all the water in the reservoir had leaked out. Thankfully, it is on a plastic shelf above a vinyl floor, no no damage was done. But, some kind of pan will have to be used under the unit. Again, keep it away from wood.

Yet another great quiet product from Honeywell! I love their quiet tower fans, and now I love this little humidifier. It's small enough to fit on a shelf in my bedroom, it puts out a very fine cool mist that doesn't damage the wall or other surfaces, it's easy to fill and clean, has a wide range of settings, and really does the job, all for a reasonable price. And did I mention, it's QUIET? (I'm highly sensitive to electrical noise, so this is a top priority for me.) In a 10x12 room, it took less than a couple of hours to go from 30% humidity to a much more comfortable 55-60%. No more dry sinuses, and no more static shocks to my cats, so win-win. It also shuts off automatically when it's empty, and there's a spot for putting essential oils (although it is NOT a diffuser).I highly recommend this humidifier for anyone who has a small space with low humidity issues.

I enjoyed this same model for the past 8 years of winter seasons (I think I got my money's worth!) and as long as I used the drop in humidifier tank cleaning cartridge and performed maintenance (even much less often than they recommend) it worked exceptionally well until it suddenly didn't. As proof for how well it works, for the four days waiting for my replacement I got a bloody nose and super dry skin.To other reviews that downgrade due to a white dust, it's due to the minerals in your water. You could use distilled water, but if you have hard water and use tap the minerals have to go somewhere. We do have hard water, but apparently not sufficient to produce dust, so you may not either.I just wish manufacturers of products often used in bedrooms would stop with their light pollution. Just as I did with my last model, I put duct tape over the knob to block it.Overall I'm super happy with the product. I hope they make them with the same quality as 8 years ago!

I have central heat and air. Both are dry air, with one being hot and the other being cold. I also have asthma, so a cool-mist humidifier is a must for me.This is my third Honeywell MistMate cool-mist humidifier. The first one I had was red. It died after three months. Thankfully, Amazon replaced my broken red humidifier with a white one. My white one lasted seven great years! I am trying a red one again. So far, it has been going strong for over a year.I mainly use my humidifier at night. The added moisture helps me rest comfortably. It eliminates my “asthma cough” from dry air. My skin, eyes, nose and throat aren’t dry, irritated and/or itchy in the morning. The lowest setting provides enough mist for me.The tank has a wide opening, is easy to fill with water and securely locks. The carry handle in the back is comfortable to use. The humidifier is fairly quiet and does not disturb my rest.I found the key to longevity with this humidifier is using distilled water. In the past, I lost two humidifiers (different brand) due to hard tap water. The calcium buildup from the hard water eventually killed the humidifiers.I clean my humidifier every few days with a white distilled vinegar solution and a scrub brush. Easy peasy and back to moisturizing.I tried the newer version, the Honeywell MiniMist, but I did not like it. It drank too much water, loudly gurgled all night and did not provide enough comfort.I am back to my faithful MistMate. She gets the job done.
