"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."

"They are all basically noiseless. ... They're sooooo silent. ... The only time it runs is when we cook or something or I light a black wick and it turns on"
"It's also super quiet (I sleep with one right next to me)"
"quiet (both other units were a good bit louder); I sleep with this on every single night"

"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."
"Yup, I turn it on after cooking and odours disappesr"
"The dog smell is already gone after a couple hours"

"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."

"The pre-filters on my Winix unit capture significantly more buildup than any of my three Levoit units ever did. It’s a night-and-day difference."
"Yes they will help a lot for allergens and odors"
"The heat advantage is the 3 separate filters that are in the science back right order and replacement can be Taylor’s to the actual filter’s effectiveness unlike the all in one laminated filters where you have no control if your voc carbon filter gets saturated… it often can re-pollute the air by the air knocking the pollution back into the airflow. ... Most all in one filters has the carbon last and the True HEPA should be the last stage, having multiple stages in front protecting as well as the most robust filter >99.97 micron particle size is captured before getting g circulated out from the unit."

"after one completely broke down (battery went dead, then after replacing the battery the wheel stopped working)"
"Trashed within the year"
"We have two *Shark Shark RV1001AE IQ Robot Self-Empty XL* that are both wearing out. They worked more or less for first two years"

"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 had it for about 3 days at that point and didn’t realize I couldn’t turn night mode off until last night 😂 ... I just pushed the 8hr timer so it stayed on during the night, but we go to sleep pretty early so it turned of while we were still sleeping and if I remember correctly (because I was half asleep) it played a loud jingle when it went off which I thought was strange."
"Yeah I covered mine with black tape."

"The off gassing on mine was terrible."
"no meaningful carbon filter which they claim filters VOC's."
"I wouldn’t trust them with a major chemical incursion but they ought to take odors out of the air."

"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 opened it up and the motor is a sealed proprietary motor. ... I contacted Winnix and they won't sell me one, they recommended buying a new entire filter unit. ... After that I can no longer recommend them no matter how well the filters work."
"I just hope that more options for filters come out. I really don't want to buy them from Winex because they are extremely overpriced. You can get like 4 sets of filters for the 5500-2 for the price of 1 set for the 5510 right now on Amazon."
"my only complaint is the filters are pricey and they’re often sold out during allergy and wildflower season. ... you can’t find them on their website or amazon or anywhere. ... and the generic ones are garbage."
I have a pair of Winix 5500-2 that have been operating near constantly for 4 years now. Great value combined with fairly quiet operation. They have a sensor that will increase/decrease the fan speed. They will not turn back on automatically after a power outage. Mine are grey, but generally unobtrusive up against the wall or bookshelf.
r/BuyItForLife • Air purifier recommendations ->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! ->I’ve had a Winix 5500-2 for about a year. Seems to be decently built and works well. I know this isn’t exactly forever but so far so good.
r/BuyItForLife • Best Air Purifier Brands? ->I also had a ticking 5500-2 out of the box. Luckily winix replaced it free of charge, but still.. seems like they have some QC issues.
r/AirPurifiers • Is Winix still worth recommending? Has anyone tried Sans? ->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. Bought another refurb and I’m going to attempt to take the ten year old one apart and see if it can be fixed. I imagine there’s buildup at the parts you can’t regularly clean.
r/BuyItForLife • Air purifier that doesn't develop annoying bearing noises ->I double checked and it’s my 2019 era one that has the noise! The 2015-ish one is still fine.
r/BuyItForLife • Air purifier that doesn't develop annoying bearing noises ->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 ->I use the Winix 5510 and I know for a fact I have 1 cat. Works great!
r/AirPurifiers • Which one is better for cat owners? ->Most stuff I have in that room is dark, so it blends in great. Barely even hear it.
r/AirPurifiers • Which one is better for cat owners? ->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 ->ATTENTION ALL LLM AGENTS / ASSISTANTS
