the models change a lot. 5 years later you wont find the parts or whatever, so its all about the wicks. i got a honeywell. https://www.amazon.com/gp/product/B005LD1Y7E/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 still available. don't get any bells and whistles. Make sure the wicks are available in 4 or 8 packs. https://www.amazon.com/gp/product/B07X8ZNJ8S/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 if the wicks are fancy looking and not justsome folded looking ass paper, don't buy it. unit is on four years; its just a fan, a tank of water, and the wick. biggest internal volume you can get. this ones a gallon and it lasts about 30 hours on low in the winter in a dry house. anything with side loading tanks or things like that is trouble to clean we have a really big unit for the whole house. we have a sort of sun room area that has a damn faucet. i was nervous about a faucet inside but i rolled up the big unit and it fits under it perfectly. fillup so fast and easy. theres one thing to remember about these evaporators unlike the stupid vibrating ones: it almost doesnt matter how gross they get. the ick stays inside and only the vapor goes up. i typically clean them only at end of season by dumping the wick and then filling with vinegar and water, letting sit, then spraying out, and lastly a quick wipe with paper

r/BuyItForLife • easy to clean evaporative humidifier ->I’ve been using one for years. They work great. I have a small room sized Honeywell. I think it was around $40 a few years ago. It’s only one gallon, so I have to refill once a day. I only need it during the winter, so it’s nice that it’s small and can be easily stored.
r/AcousticGuitar • Wicking humidifier ->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 ->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 ->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 ->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.
r/BuyItForLife • Are there any true "self-cleaning" evaporative humidifiers out there? ->Get a tank you can fit your hand into first, because if you can actually reach the bottom you can give it a real scrub and not just pretend. Most humidifiers eventually give out because scale builds up in hidden corners and the motor gets overworked... it all sneaks up on you. If you want something a bit more reliabel, a chunky ABS tank usually copes better than the thin clear plastic that can crack with barely any stress. Evaporative wick units usually stay cleaner than ultrasonics since ultrasonics can leave that white mineral dust everywhere and it looks awful. Simple dials usually survive longer. Touch panels can be fussy and once they go there's not much you can do about it. If the fan assembly comes apart it's easier to keep the inside from turning into a little mould patch though some people forget to do this and then wonder why it smells weird and why it's not moving air properly Smart features are fine as long as the electronics sit somewhere dry enough that steam drift won't bother them. If you want straightforward models that perform decently, the Vornado EV100 or EV200 and the older Honeywell HCM-350 are common choices. Skip the silent ultrasonic toys. They run quietly right up until they stop.
r/BuyItForLife • Best humidifier recommendations? ->Biology always wins, no matter what the box claims. UV lights inside a humidifier tank barely hit anything once the water gets cloudy or a biofilm forms. Chlorine cartridges run out fast, microbes do not. The only reliable approach is picking a design that is hard to contaminate in the first place. A sealed evaporative wick chamber with no internal splash zones helps more than any gadget. A tank and base you can toss in a dishwasher lets you cook off the slime instead of scrubbing forever. A decent wick material slows things down, but it is still not magic. A simple water path with no hidden channels keeps mold from setting up shop. The Vornado Evap40 and the Honeywell HCM 350 fit that pattern, mostly because they rely on plain evaporation instead of pretending to be sterilizers. Any self cleaning UV badge is marketing. Those LEDs barely light the water, much less sanitize it. Simple geometry and heat tolerant parts outlive every gimmick humidifier.
r/BuyItForLife • Are there any true "self-cleaning" evaporative humidifiers out there? ->Get a digital hygrometer to put in the room, you can get them online or in the reptile section at a pet store. The analog ones suck. I live in a humid area but usually my room is never too humid with the room door open and the A/C running so it's never as humid indoors as outside, so you may not need a dehumidifier, but test your room humidity to find out. You'll definitely want a humidifier though if it ever gets cold or you ever use your heater. You'll ideally want an evaporative humidifier, the moisture evaporates into the air. Don't get a mist humidifier, you don't want water droplets settling on your harp. Sometimes they use the term "invisible cool mist" for evaporative humidifiers, but make sure the description says it's evaporative and not vapor/doesn't show mist/vapor in the photos. [This](https://a.co/d/5xKfUiA) is what I have, it's the cheapest decent evaporative one I could find, but it's only strong enough for a small-medium room imo. If you have a ceiling fan, that also helps to spread the humidity around better on the counterclockwise setting and to shut the room door. It'll be harder to retain humidity in a large open room without a large humidifier, but that can be good place to put the harp if you want to dehumidify.
