Honeywell - Cool Moisture Humidifier HCM350B

We have an ultrasonic in our bedroom and a matching one in our home office. We use distilled water. It's cheap and makes maintenance a snap. I had one of the big evaporative ones years ago and it was a PITA.

The model we have is discontinued, but it's somewhat similar to this one. [https://www.amazon.com/Honeywell-HCM350B-Germ-Humidifier-Black/dp/B00FJTVHKO/ref=sr\_1\_2](https://www.amazon.com/Honeywell-HCM350B-Germ-Humidifier-Black/dp/B00FJTVHKO/ref=sr_1_2)

I got the white version of the Honeywell HCM350B, kind of expensive at like $70-80 but I bought mine in 2019 and it's still going strong. I chose it based on a Wirecutter article that pointed out how easy it is to clean everything, including the tank.

This is what i use. It's cool mist with a uv light which to be honest ti should check to see if it's burnt out. I like that it's cool mist. It has a filter. And with the fan it doubles as my white noise machine https://a.co/d/gFZLxJJ

I also live in WI. Do not buy any ultrasonic humidifier. What you need is a wicking humidifier like the honeywell HCM350. Easy to clean. Don't need distilled water. 

Mine are disposable. I have both an evaporative humidifier (Vicks Warm Steam) and a cool mist (Honeywell HCM350). I soak the cool mist filters in vinegar, and soak the evaporative motor/filter part in about 4-5" of vinegar. Removes mold and mineral buildup from both.

Those Honeywell filters are NOT cheap! I got tired of paying $25-30 for 6 filters that you're supposed to change every month. Soaking them in vinegar allows me to get up to 3 months from each filter.

I started soaking my filters in vinegar. It dissolves all the buildup, and I get twice as much life out of them.

i got the honeywell hcm350 but don’t know if it will be good enough!

it’s okay! it works and does help with humidity but i wish it had a digital humidistat to turn it self off. the unit is also fairly large and i wish it was smaller. I also wish the tank was bigger as it’s kind of annoying to flip the filter and refill it everyday. I probably could do it every other day. I will say that the filter stays relatively clean after using the deminirlization tablets and aftermarket filter from amazon. Also being able to throw like most parts in the dishwasher is awesome for cleaning . comparing this to a previous levoit ultrasonic and i like that it’s way more healthy. No mold in tricky spots (yet anyway) and i feel like i can do an easier job of keeping it clean for my son. I do change the wick every 30 days as well .

No. they all suck and it is frustrating. An ideal situation is to have a whole home humidifier and just have to keep ontop of one filter and cleaning but of course not everyone can do that (and those have their issue too). I'm also a busy working parent and just decided to try going without a humidifier this year and see how it goes. Try to see how they do. In the past, i've utilized the Honeywell HCM350 and run what parts i can through the dishwasher and clean the rest as best as i can as often as i can (prob every 2-3 weeks realistically). I keep eying the Levoit 6000s but i don't have a spacious place and don't have excess funds at the moment or the capacity to try something and deal with returning it, etc. all this to say, as a parent, you are not alone, it is super frustrating and i wish there was an easy to use humidifer for our little kiddos. I grew up with sinus issues and at this point in my life, i feel like i've tried so many humidifiers and am just tired of it.

Been happy with our Honeywell evaporative humidifier. I’m not sure the model exactly as it’s older but the HCM350 seems to be at least very similar if not the same

Mine are all in small bedrooms; you’d probably need slightly larger models for a living room. I did use the HCM350 for a few years, but after a while, the threads on the tank lid stopped sealing properly which made it really annoying to refill. The model smaller than that didn’t have this issue as soon, but they stopped making them, which is when I bought the Walgreens version of the same size. These have seemed to last me about 6 years of daily use in winter only. Last year I bought an EV100 whose tank lid seems to be better designed (1/8 turn twist to lock, instead of threaded) but I’m not sure the airflow to/through the flat wick is as effective as the round ones. For a larger space, maybe Vornado’s larger models are worth checking out? The Venta ones look interesting, a different design altogether with no wick. I’d be interested to hear opinions on those!

I just replaced an HCM350 with an EV100 in my bedroom last year (this is my second winter with it) I had the Honeywell for 7-8 years, running it nighty from October through March. In Chicago for half those years and now in PA. The Honeywell worked great! The reason I replaced it was the threads on the cap of the tank stopped aligning correctly, so after filling the tank and doing my best to screw the lid back on (which ended up being a pain after a few years) it always dribbled a little when I inverted it back onto the base. Once it was there, it didn’t leak or anything, and the humidifier still performed well, so I lived with it for a year or two before I became fed up with it. The Vornado doesn’t have that issue, it doesn’t have the same type of screw-on lid. The lid of this tank kind of just twists ~1/8 turn to lock. It does run louder, so if that matters to you, the Honeywell is much quieter. Because of this, I almost never run the Vornado on high. Even the low speed is louder than the HCM’s medium. HCM’s low is almost inaudible. About the filter in the Vornado- it’s flat, and the incoming air hits it right in the center. So, even if you flip it periodically, the same middle band area gets dusty and crusty (minerals from hard water). Regardless, I seem to have been getting about 6 weeks out of the filter, same as the Honeywell. YMMV depending on usage/water hardness. TLDR: Vornado louder. Honeywell had tank lid issues after 5-6 years of use. Both are effective in a bedroom.

Smart switch and humidifier. I like my Honeywell HCM-350 a lot. Gets the whole room humid very quickly

Fwiw I hated the Honeywell HCM 350 after 6 months. The plastic tray still ends up pockmarked and eroded with regular use. Went through 2 units and gave up on humidifiers altogether.
