All day humidity

On the lowest setting this will run all day on a full tank which is good for maintaining a base humidity. The highest setting will still run for several hours. This a big improvement over my previous humidifier and the benefits are noticeable especially during winter months. I've had it for two months with no issues. Regularly cleaning the filter is probably a good idea. I take it out and let dry once a week. I run it through water before putting it back.

LOVE IT!

This is the BEST humidifier on the market for hard water in my opinion. Daily/Weekly cleaning is very minimal and its pretty quiet. I live in a decent-sized studio apartment and it keeps the humidity steady. When I first turned it on, I turned it to high because the humidity was 18%. After about an hour and a half, it was up to 52%, so I switched it to low. I can keep it set to low all day and night and the humidity will stay around 42-45%, it's wonderful. The difference was tremendously noticeable after just the first night. I woke up with a clear nose, I slept with my mouth closed, my eyes weren't itchy and red I have severe dry eyes and skin, and my head didn't ache. Definitely get the humidity monitor with digital display, as well as the antimicrobial cleaning cartridge, and change the filter every 30 days. I have had this for a month and there is no slime in the base, nor is there the stale/moldy smell that was typical in humidifiers I had before. The tank and base are completely separate from the machine, so the chance of mold and mildew building up seems next to impossible to be able to occur. I don't have a dishwasher, so every week I wipe the base and tank with vinegar and it works just fine. I pour a decent amount of vinegar into the tank and shake it vigorously without the cleaning cartridge and after rinsing both the tank and base thoroughly, there is never a lingering smell of vinegar. Do NOT waste your time researching humidifiers, this is hands down the best one out there for hard water! I am not certain if its meant for filtered or distilled water, but if it is, get it!

Terrific product

This product keeps the air in my 20x20 bedroom just right and I barely notice it running on low and moderate setting. It is audible at the highest setting but it is a soothing whir. Best of all, no more dry, cracking skin or bloody noses in the morning! I wouldn't say that it is completely going to eliminate the white powdery residue in your house unless you use filtered or distilled water but it makes a huge difference compared to many other comparable units.

This unit is very easy to maintain, but I noticed the filter is tinted light brown on the fringes after 3 days of use with distilled water in a well maintained, clean home. I will need to research that, thus the 4 stars.

Humidifier

Works well. I have it in my bedroom and it really helps me to sleep better and not wake up several times to drink water. The only thing I would like to see is more output at lower speeds. The quietest speed, the one they say is for sleeping, does not put out enough humidity to help. It has to be on the number 2 speed at least to work well. I have learned to sleep with the extra noise because the 2nd speed is the lowest you can go and still get a good output.

Nice humidifier

I switched from a vapor humidifier to this one where you do not see the moisture, and I have to say, it is a bit tricky at first to know if it is working. I can tell you, though, that once the filter started to get old, I did notice the air getting drier and there was less water being used up in the tank. I do recommend this item - also it is nice to not have any moisture damage from normal humidifiers. Just a word of wisdom - be weary when buying replacement filters. There are a lot of fakes out there that are nowhere as good as the genuine Honeywell filters!

Every time I touch something, it would shock me. This machine has good reviews so I tried it. I was surprised at how quickly it worked. The only thing it doesn't do, is notify you when you need to refill the canister. Quiet running too.

Excellent with one flaw

The humidifier works really well, and is wonderfully quiet and unobtrusive especially on the lowest setting. The one flaw I have found is that if you don't run it continually, 24-7, the filter begins to dry out immediately, and prevents the machine from dispensing mist. I had hoped to run it only overnight, but that will not be possible.

Good Product

We have used the Humidifiers for a week. It works as stated and was easy to set up. Your personal tolerance of white noise and how close you can site your humidifier to the proximity of your head will determine the degree of how well moisture is provided. This statement is based on one of our humidifiers being operated close and another being placed about 5 feet away. The fan speed was set a medium for both humidifiers. Do not expect them to humidify a large room. Based on this same product being operated in a different household for about a month, I am a little concerned about the amount of filter replacement that may be required. Yes, soft water is being used but mineral and fine Iron residue is being trapped on the filter quickly. I have rinsed the filter once but not sure about multiple cleanings.

Works for me!

Had a problem with my ultrasonic humidifiers: new cat was knocking them over. So decided to try an evaporative humidifier and this one looked good on paper. It's quiet, even on the high setting, and I no longer have headaches from dry air--which is the main reason Ive had humidifiers since the 70s. It looks good and while the cat occasionally moves it, most of the time he leaves it alone. The only problem is the tank is on the small size and I have to frequently refill it. May eventually get a larger one, but will most likely get Honeywell again.

Very quiet!

I bought this for my bedroom and it works very well, keeping the humidity level between 40-50%. The tank is very easy to fill and has a large opening for cleaning. I run it on low at night and can hardly tell it's on, it's so quiet. I run it on high during the day and will use most of a tank of water.

The Honeywell Humidifier HCM-350B is very quiet. On the lowest setting you cannot even hear it, although we needed to use the second setting to get the humidity up to 45% in our small bedroom. The water lasts 2 nights sometimes more before needing to be refilled which is a nice feature. It is easy to fill and carry the water holder, however it is too big to use the smaller bathroom sink to refill it, which means a trip to the kitchen. Overall, it is just what we were looking for and were very happy with it so far about 2 weeks of use.

Looks sleek and works well

This is one of the few humidifiers I was able to find in black, and also one of the most highly reviewed. I am very satisfied with the moisture it provides. On the highest setting it is somewhat loud, but the sound is not annoying. It is even effective as white noise for sleeping, in fact. I am able to run it on high for two nights with one fill of the tank. I am very happy with this purchase.
