Effective and Easy-to-Clean
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.

Great filter
Great humidifier – works well. I don’t wake up with a dry throat/coughing anymore. Only problem is the filters have to be replaced monthly during the winter in our home and the replacement filters are expensive. One nice convenience is that the water tank lasts 2.5-3 nights so I don’t have to worry about filling it every night (or multiple times a night) as with some other humidifiers.Level three is too loud for me to sleep with, but I can usually keep it at level three before bed and then lower it to one right before bed through the night.

Great humidifier with one minor flaw
This humidifier works well. I was waking up with bloody snot (gross!) almost every morning due to dry nasal passages (and sleeping terribly as a result); running this humidifier put a stop to that overnight. I slept well for the first time in weeks, and my nose is 100% fine.It’s silent on the lowest setting, almost too easy to disassemble for cleaning, and very easy to refill. I read in other reviews that this thing consumes mineral filters quickly, so I’ve been filling it with distilled water.However, it has one minor flaw: the water tank is translucent, which sometimes makes it very hard to read the water level. Condensation often collects on the inside of the tank, which when combined with the translucency, makes it hard to see the actual waterline. If Honeywell made the tank out of transparent plastic, this would be a 5 star product.

Worth the money
A bit pricey, but it works as described. Very easy to fill, extremely quiet even on the high setting. We cannot have ultrasonic humidifiers in our home. This absolutely filled our need.

Excellent humidifier, but you have to understand how to use it.
I bought this a few months ago. At first I didn’t like it and was ready to return it. Then I figured out how to use it.This is an evaporative humidifier and works in a completely different was from the ultrasonic humidifiers I had in the past. There is a large, cylindrical filter inside which absorbs the water and then evaporates it into the air with the aid of a fan. The fan is clearly audible but actually works well as a white noise machine. In our bedroom, which is about 25′ x 15′, we go through about a gallon of water every 12 hours.Here are some pearls about using this unit:-It MUST be on a level surface. At first I had it on a towel over the carpet in our bedroom. This caused the water to be unevenly distributed in the base which in turn led to the filter not being properly moist.-The filter must be wet at all times. In an ideal world this would happen without any effort on the part of the owner, but that is not the case here. Sometimes the top of the filter dries out, resulting in less evaporation/less humidification. The manufacturer (and other users, in reviews) suggest flipping the filter every time the tank is filled. I find that it’s sufficient to do it when the tank starts to empty more slowly (i.e., I don’t have to fill it as often), which is about every 5-10 tankfuls.-Sometimes the filter gets so dry you have to remove the filter and moisten it under the faucet (this is especially true if the water in the tank runs out. There should be an automatic cut off, but there isn’t). It’s a bit messy in that you’re not supposed to wring out the filter, so it drips all over the place.-The filters discolors from minerals and particulates in the water. This is normal (hey, it IS a filter) and does not interfere with the operation of the unit.One could easily argue that using a humidifier shouldn’t require such a long to-do list, and I wouldn’t argue the point. Having said that, once you get the hang of it this unit works extremely well, humidifying the air without coating the furniture the was ultrasonics do. I highly recommend it.

Used this for my bedroom and I really like it because it’s not a warm air humidifier as I often get too hot whilst sleeping. Nice and quiet on the low setting for sleep. Can make the room a little colder feeling from the humidified air in the colder days but I have been waking with clearer breathing since starting to use it. I bought a thermometer/hygrometer as well to keep an eye on the temperature and humification and on the high setting it humidifies the room quite quickly (3.5m sq room)

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 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.

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.
