Honeywell Cool Moisture Humidifier For Bedroom, Medium Rooms, 1.1 Gallon, Invisible Moisture Humidifier for Baby, Kids, Quiet, Easy to Clean, UV Technology, Black, HCM350B

Before this, we used an ultrasonic humidifier, which was certainly quieter but didn’t perform as well as this one, so it was a great upgrade for us. Noise: at its second speed, it sounds like an average house AC and does not interrupt sleep. Humidity: we have a 12×11 room, and it humidifies the space very effectively—you can feel the difference without needing a humidity meter. Ease of use: as simple as it gets. Cleaning: much easier than our ultrasonic humidifiers, which had many small spaces that were hard to clean. Cleaning this unit is very simple, though you should remember to flip the filter every night and replace it every month or two. Overall, it’s better than other humidifiers we’ve tried, and I definitely recommend it for small to medium rooms.

This is an excellent machine. Easy to put together, easy to use - holds a large amount of water so it doesn't have to be filled every evening. Works for our large master bedroom and has significantly cut down on the coughing (our floor heaters really dry out the room in the winter.) The filters and UV protection are great - filters are easy to change (although we haven't had to do that yet). I would absolutely buy this again - no white dust residue!

Works well in a small bedroom. Noise lever on low is acceptable for sleeping. Like the evaporator type since it doesn't spew chemicals into the air. Using it with tap water and haven't had any mineral depost build up yet. Seems well made. Easy to fill and clean.

We bought this product to support our whole house humidifier in the coldest, driest weather. We are using it in the master bedroom (approx. 12 x 20 with a vaulted ceiling). On the medium setting, it raises the humidity about 10% and runs about 20 hours before needing a refill (we use reverse osmosis water). The unit is easy to set up, refill, and clean (top rack dishwasher safe) and is no louder than a small fan. Occasionally there is a slight gurgling sound as the water level drops, but it's certainly not annoying. I'm a light sleeper and really don't notice anything. We have all noticed the improvement in our skin and noses, plus our cats are happy to be rid of all the static. We are very pleased with our purchase and highly recommend this product.

Was hesitant to buy another wicking humidifier because they can be a hassle, but this model is well designed and engineered. The water tank is very easy to remove, refill, and replace, which is important because you’ll be doing that frequently. The unit also disassembles extremely easily by just lifting the top part off the base. Bravo. Bottom line is it also works to increase room humidity a small but noticeable amount, but keep in mind that it’s not going to change the humidity by a huge amount, none of these portable units can really do that.

This humidifier replaced an old Honeywell humidifier that I had for years. I wasn't sure I would like the size since it is smaller than the previous one, but I really like it. It's convenient to fill the water reservoir, easy to clean and quiet. I keep it on the low setting and let it run all day long since we live in a dry climate.

Quiet, Effective. Wish it had a larger tank as it empties in about 18 hours. But that means it is putting moisture in the air.

Reviews should allow a zero rating. That is what this experience deserves. The humidifier did not work. Follow the instructions, fill the tank, soak the filter, set unit on base, plug it in, and nothing. No lights, no hum, no air flow, at any switch position, nothing. Tried several different outlets, still nothing. Checked power, yes we have electricity. The unit is so dead it must be something simple. Take unit off base, find safety switch on bottom, activate switch manually, and the unit runs fine. The problem is with the plastic base. The plastic is either malformed or warped. Tried setting unit on hard floor to better support the base, still nothing. Pushed down to make sure unit is fully seated on base, still nothing. The defective base/switch is a safety feature. If the unit should ever get knocked over, the switch kills all power so someone doesn't get electrocuted. That's a good thing, but nothing I've tried will make this unit work with the base that was provided. Feb 13 - Contact KAZ customer service. Yes, it's some outfit called KAZ, not Honeywell. Got an automated reply saying it will take 1-3 days for them to reply. Feb 19 - Got a reply from KAZ with the usual platitudes. Rather than a solution, this message is asking for more information such as model number, date code, and mailing address. This is all the same information they needed for the warranty registration. They already have the information but it was easier to just reply with the requested info. Feb 23 - Got a reply with a return merchandise authorization number and instructions for returning the defective item. This message also indicates a shipping label will be provided in a separate message. Feb 26 - Finally got a message with a link to print a shipping label. Feb 27 - Shipped defective item to KAZ. Mar 5 - Received confirmation that defective item was delivered to KAZ. Mar 12 - It's been a week since the defective item was delivered to KAZ. We have received zero communication regarding the status of our returned item or any replacement. It really shouldn't take a month to resolve a dead-on-arrival device. Update 14 MAR - Replacement WHITE unit was delivered last night. KAZ did tell me replacement humidifiers were only available in the white model. The new model seems to work as it should. It used a little more than half a tank of water overnight, running on medium setting. Maybe the factory defect is only occurring with the black model. If they had sent me a black one and it worked, I might have added a star or two. Based on this experience I have to recommend not buying the black model.

I bought this humidifier over 5 years ago and it is going strong. Just take care to clean it about once a week with vinegar and rinse and flip the filter daily (and replace it when it gets crusty - but it lasts a long time before that happens) and it will work very well. I keep it running close to 24 hours a day, often on high, but switch to medium or low for very quiet operation. It is apparently rated for use in a room up to 400 square feet, but it does a great job in my 700 square foot apartment, all throughout the very dry Ontario winters. It raises the humidity from 20-25% to 35-45% which makes a significant difference. Helps alleviate dry skin, eyes and nose. I keep it on a little rolling metal cart from IKEA, which makes it very easy to move around. Very highly recommended!

Honeywell warranty not available in India on humidfier. The seller is a real fraud, i dont think the items imported are used ones... The humidifer stoped working within 5-6 nights only... seller took it from me for refund, its been more than 20 days and no call/reund from seller... its really disheartening, after buying the premium product i have to face such an experience.... The seller is a real fraud... pls dont buy... its a clear recommnedation from my experience. Otherwise, be ready for such an experience. Choice is yours because the money is yours.. Anyways the filter turned yellow within 2 days of use (that too after i used only mineral water).

This is a fantastic humidifier. It is very easy to clean as long as you use common sense and check it every couple of weeks. The wick does require descaling if you want to use it for more than two weeks and any kind of descaling agent will do. I generally replace my wicks after 4 weeks of use. If you have hard water, you might have to do it more often, just be prepared. Noise is minimal as it is simply a fan running it, and I find on the medium setting I am getting good humidification without too much noise. Because it is an evaporation humidifier, there is no white dust settling from its use. Absolutely no issues with mould forming, most likely because I leave it running all the time and there is no standing water.

This review is based on use over a full winter season of this version of the HCM350 with the internal UV light that is supposed to kill 99% of bacteria, mold, etc. 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.

Pretty simple design and construction, which is good (the less complex, the easier it should be to maintain). Water tank has a wide mouth and is easy to refill. Most hands won't fit through the mouth to scrubs the inside of the tank, but you can quickly disinfect it with a diluted bleach solution with no scrubbing. UV light is an interesting feature - I'll wait to see how effective it is in the long-run by observing if the plastic exposed to the UV light discolours over time. I live in an area with really hard water so the filter was quick to discolour, but I try to briefly rinse it out between tank refills to help with it. I live in a condo that's just under 600 sq. ft. I bought one unit hoping it'd be enough, and it helped raise my condo's humidity level from 39% to 45%, but it's not steady and will drop from time to time, meaning one of these units isn't enough to keep my condo at a good humidity level. So I'm now buying a second one! Cold Canadian fall and winter seasons really take a toll. I really like that the unit is stylish (compared to other humidifiers out there). It's pretty quiet - my current unit is sitting on my nightstand next to my bed and I can keep the fan on the medium setting with no issue. It is audible on the high setting so I'd avoid that when trying to sleep. The one feature I wish this unit had was auto-shutoff when the tank is empty so that I don't need to worry about it, but I tested running the unit on high for 8 hours straight and there was still ~1/6th of the tank left, so it should be fine to leave on while you're at work if you're out of the home for 9-10 hours. 20/10/2018 UPDATE: my one unit is starting to struggle now as the weather gets colder and drier. Even on the high fan setting, it's not able to raise the humidity past 37%. So one unit won't be very effective in a 600 sq. ft. space. Very much hoping the 2nd unit will get the humidity up when it arrives. 02/11/2018 UPDATE: with 2 of these units running for a week now (with one always on high and one always on medium), I've been able to maintain 41-44% humidity in my condo. Kind of disappointing to be honest, and I'm worried when the real winter hits in a couple months, these units will be very ineffective. One trick I did pick up to help with reducing the amount of mineral build up and hardness on the filters is to flip the filters to the other side once a day. Since I started doing this, I've noticed the mineral discolouration (from build up) on the filters are noticeably less, and the filters don't feel as hard.
