"Literally couldn't think of any pair of IEMs + dongle dacs could sound as analytical as the C3P+ for around $70. ... detail is just sooo much better. The C3P+ is just leagues ahead the I5 in terms of detail and resolution. ... the C3P+ is actually the closest sounding one to really expensive iems or headphone that I have."
"Crazy good from the jump! ... When you factor in they're only $99 and go toe-to-toe with Bose QC Ultra at $299, this is the deal of the year!"
"Can't recommend them enough for the value, sound like $200 earphones."

"I recently found out I have a bunch of allergies- including my dog, so I got these Winix units to try and help combat the allergies. ... Within about 45 minutes of running one in my living room, part of my nose that has been clogged for as long as I can remember opened up. I’m breathing better than I have in years."
"I can tell you they really work. I have a mold allergy, and mold is literally everywhere in outdoor or indoor air with spores just waiting to land in a suitable environment for growth, but I have no symptoms at home with my two small Winix."
"They are also great to have during annual west coast wild fire smoke season and keep particulates in the house undetectable even when it has been horrid outside."

"We have indoor animals and almost a year later running 24/7 no issues. ... It’s just not the workhorse Winix is."
"I've had a Coway airmega going 24/7 for six years that hasn't developed any noise problems"
"I got annoyed when my winnnix developed a noise, but then I realized it was the unit I’ve been running almost 24/7 for ten years. ... The 2015-ish one is still fine."

"within months of each other the bearings on both started making a horrible noise ... it turns out it's very common ... it's nearly impossible to fix because it's a sealed system ... They cheaped out on a 10 cent bearing and now they're pretty much useless"
"I have two and the motors are going bad on both after a few years. ... I have some 5500-2's and the motors got super noisy because the bearings are going bad."
"I would not recommend the winix 5500. I bought 2 a few years ago and both had the bearings go out after a couple years of usage. Turns out it's a common issue."

"All of the conventional options recommended won’t cut it if you’re being serious. ... I have a few coway airmegas and blueairs and they don’t do much for real VOCs/smoke. ... My airmega has like 1lb of carbon, I’d recommend an allerair- I’ve got two airmedic 6 pro and the difference is remarkable. I think they have 25+ lbs of carbon."
"I bought it to reduce VOCs, however according to my sensor it loses effectiveness in under a month, then you are on the hook for a new $300 filter. ... A replacement filter lasted a similar amount of time for VOC effectiveness."
"So I purchased Austin Air Healthmate+ HM450 believing the higher carbon content in its filters will be more effective but after I tested it today it is also not making much of a difference. ... Austin Air HM450 has 15 lbs of activated carbon. Is that also not enough to make a dent? ... There’s no wildfire smoke currently. But my Voc is at around 225ppb. And no matter for how long I run the purifier, it stays at that level."

"this unit has a annoying light sensor that doesn't allow it to run in auto mode in the dark. The sensor is silly and I wish I could disable it."
"I recently got a Winix as well that I like although it has a light sensor so it knows when to go into “night mode.” I thought I would like this feature until winter hit and the sun started setting at 4:30 pm and my air purifier thinks it’s night time and isn’t detecting contaminates without a light on near it."
"The Winix has a light sensor that doesn't allow it to work in auto mode in a dark room. ... If I put mine in auto mode and turn the room lights off it goes into sleep mode which is basically turning it off."

"I literally just bought the Airmega 350 on Amazon and immediately regretted since I can't find the replacement filters for sale anywhere. ... Coway finally responded but wasn't helpful. They said they don't know when the filters for the 350 will be released."
"450 is round. New design. Not as good but more trendy. ... Higher claimed CADR. It is round so that number will go down rapidly. ... The VERY SHORT version, although ... there's a sticky ... is that round units are not inferior due to their shape. They're inferior because ALMOST WITHOUT EXCEPTION they have: * No removable pre-filter * Minimal Carbon, placed after the main filter * Deformable main filter * Smaller fans which have to spin faster to move more air therefore have a shorter lifespan * Shorter filter life leading to more costly replacement * Questionable filter efficiency, since it's difficult to manufacture a deformable HEPA filter. Levoit in particular claimed their filters were HEPA but they weren't at the time. They might be now, since they've started shipping them reinforced. * Instructions to VACUUM YOUR FILTERS, which pretty much means they're not HEPA. ... The airmega round units are, unfortunately, no exception."
"filter replacements can get pricey though ... filters are WAY overpriced considering you can get the machine with 2 filters for $120.."

"Both of my Winix air purifiers started smelling like smoke"
"The Winix ones did an okay job, but the Alen ones are incredible. We have a 75i in the open living room/dining room/kitchen area and a 45i in my spouse's office, our bedroom, and one of the guest bedrooms. The 75i and all but one 45i have the fresh filters and the office 45i has the VOC/smoke filter. They're surprisingly quiet, even on turbo mode. Not inexpensive, but the investment in our health was worth every penny."
"In combination with my Winix ones it definitely makes a difference. I can’t afford to buy a house and this apartment is rent controlled so I’m not going to move. I just want to make it livable until management gets her out or something happens."
Both of my Winix air purifiers started smelling like smoke, they are different models, cleaned weekly and filters changed regularly, I don’t recommend them.
r/Costco • Need Help Choosing an Air Purifier from Costco—Totally Lost Here! ->you can't beat the physics. what you want is the big size as prioirty thing to look for first. then you can look into other things but the size of purifier(filter) has biggest impact. winix is solid imo for basiaclly 99% of the use case.
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->Winix seems to be the play here. I have two and they seem to work and are common enough for filters to be inexpensive. The prefilter is easy to clean. I did recently have a DOA unit but the replacement was easy through Amazon.
r/AirQuality • Air purifier ->Any filter with a charcoal filter layer will help some (Winix is one brand commonly available at Costco…I also have a more elaborate Rowenta)…my Winix came with multiple charcoal layer replacements. Dealing with total incontinence here, and not to criticize your MILs efforts, but you might want to look into the actual sources of the odors. Chairs, clothes that sit around waiting for wash, previously soaked furniture or carpet? If bedding or fabric furniture smells and you can replace it, do so. I use a combo of Depends on my father, and all his sleeping or seating surfaces have a first layer of puppy pee pads (Costco has large ones that work well and are cheap), and then a fabric layer on top (whether sheets or a chair cover or towel, tucked into the sides of the chair). Once he’s wet, after I changes his pants all clothes and chair covers and bedding goes in the wash (3-5 loads a day). For the mattress you can find on Amazon washable mattress covers (the whole bed ones don’t work that well but that’s my base layer and then a thicker more absorbent one that I fit across the middle section of his bed, and on top of that layered dog pee pads). So again, not sure if any of this advice helps but this method works for me.
r/CaregiverSupport • Air purifier for urine smell ->Definitely recommend Winix. Australian and comes out top of various tests. (If you haven’t been warned- don’t buy Dyson) Super sensitive to more than just particulates and has a ‘pet filter’ that is changed monthly that goes around the main filter and prevents it getting clogged with dust. Helps to prolong its life if you have pets
r/AusRenovation • Air Purifiers ->Winix is a solid air purifier, but not this model. This only uses a thin filter, no charcoal. The true HEPA rectangular ones are not that much more but work so much better.
r/Costco • Any thoughts on pictured air purifier? ->There's also the Winix D360/480 series as a Home Depot exclusive, which doesn't have ionizers and has a pretty high CADR rate. I don't think there are after-market filters but Winix said they continue to manufacture filters for 10 years after so maybe you won't have problems. I'm eyeing it. Honestly my first air purifier was BlueAir and I loved it. Dead silent on the first setting (I think having a vertical fan helps), and I could run it on the high setting all day. I have birds and had no idea about the ionizer though. I've gone through one Honeywell which made my room smell like a plastic pool toy, and I'm not so happy with the return-replacement either, I ran it on turbo today and got a pretty big headache and felt like I was having trouble breathing, which sounds insane but it stopped when I turned it off. I'm almost tempted to just go get another BlueAir and remove the ionizer manually, but I also know that their CADRs are based off of ionizer on, and the larger sizes have significantly more expensive filters.
r/AirPurifiers • I’m lost ->Winix works great ! I have 2. Zero complaints.
r/BuyItForLife • Best air purifier in 2025? Need recommendations! ->Winix is fantastic and well-priced
r/BuyItForLife • The Best Air Purifiers? ->AVOID DYSON AT ALL COSTS!!! They look cool but are RIDICULOUSLY overpriced for what you get. Spent $500+ on one and my cheaper Winix outperforms it by a mile. Total marketing scam.
r/buyforlifetips • Best Air Purifiers for Home Use? Recommendations Needed ->I would buy whatever Winix fits your budget and space. My two Winix units are 11 years old with 24/7 use and still going strong!
r/AirPurifiers • Best Air Purifier under $250? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
