Honeywell makes a nice on that I got. It’s the HCM-350. Super simple, cheap and just has a paper pickup reed you can replace if it gets icky. There’s a UV bulb that is in there to kill bacteria and is the only real wear item.
r/BuyItForLife • easy to clean evaporative humidifier ->Interesting, I haven't had a single issue with it tbh. Works quite well.
r/BuyItForLife • easy to clean evaporative humidifier ->I have the Honeywell evaporative humidifier. Most of it can go in the dishwasher. The biggest pain (which is only a pain to remember, not to actually do), is to flip the filter daily to make sure it doesn’t dry out in places.
r/NewParents • Do you use an air purifier/humidifier in your baby's room? ->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.
r/YouShouldKnow • YSK: Using Tap Water in Your Humidifier Can Seriously Harm Indoor Air Quality ->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.
r/YouShouldKnow • YSK: Using Tap Water in Your Humidifier Can Seriously Harm Indoor Air Quality ->I started soaking my filters in vinegar. It dissolves all the buildup, and I get twice as much life out of them.
r/YouShouldKnow • YSK: Using Tap Water in Your Humidifier Can Seriously Harm Indoor Air Quality ->Yea only use one system in the case. The humidipaks work in both directions. They add humidity if needed or reduce if too high. The best option will always be to control the ambient relative humidity in the room, though. This is the humidifier I use: [https://www.amazon.com/gp/product/B002QAYJPO/ref=ppx\_yo\_dt\_b\_search\_asin\_title?ie=UTF8&psc=1](https://www.amazon.com/gp/product/B002QAYJPO/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) It does not have a built in sensor/hygrostat, so I check humidity with the hygrometer and adjust as needed. But basically in the winter it needs to run all the time.
r/martinguitar • Tips for humidifying (Philadelphia) ->I’ve had this Honeywell humidifier for years and it’s about as low maintenance and care free as it gets. It’s plugged into a smart switch and turns on and off to keep the humidity just where I like it. One tip to prolong the evaporator wick is to rotate it every time you refill the tank. Doing that the wick will last through a dry season. https://www.amazon.com/dp/B00FJTVHKO?
r/BuyItForLife • "Cheap", easy to clean, dumb humidifier(s) for 1024sqft apartment? ->i got the honeywell hcm350 but don’t know if it will be good enough!
r/BuyItForLife • Best humidifier? Enough for a regular size bedroom. ->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 .
r/BuyItForLife • Best humidifier? Enough for a regular size bedroom. ->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.
r/Humidifiers • Can humidifiers really affect kids’ respiratory health? ->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
r/BuyItForLife • do all humidifiers suck?? need recs for one that’ll actually survive the winter ->Me too, I've had one for years.
r/BuyItForLife • easy to clean evaporative humidifier ->Skip the misting ones. They can really mess up your air quality, and kind of alarmingly so. You want a regular evaporative one, with the wick. The $60 Honeywell one is fantastic. We leave it running basically 24/7 on medium, cranking up to high at night. It’s about a dollar of electricity a month. It claims to have a UV bulb that helps prevent mold growth. Idk how true that is, but we haven’t had any problems. A tablespoon of hydrogen peroxide every now and again.
r/BuyItForLife • Advice on Humidifier ->Does your house have an HVAC system? If so, I purchased a whole home evaporative unit and it has been a blessing. I could not, for the life of me, get the humidity to even passable levels with multiple portable evaportive units (which makes sense as the whole home unit is putting upwards of 10 gallons a day into the air on the driest days of winter.) If not, we had portable Honeywell systems, which were well designed (but inherently limited on what they could do if you are in a super dry area.) If your water is hard, you will have to change the filter more often (as is the case with any evaporative unit).
