"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."

"The dog smell is already gone after a couple hours"
"It has a nice pelleted carbon filter which is great for odors. ... I’m a weed smoker and my Winix has made a night and day difference compared to the Airmega."
"When I have guests over, they have always commented on how they can't smell the cats and ask how I do that in such a small space lol."

"the HEPA helping with my allergies immensely."
"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."
"It wasn't until I upgraded to 2 winix machines that I finally got relief and it was instant."

"My two Winix units are 11 years old with 24/7 use and still going strong!"
"Winix makes a quality product. ... I have one that’s run basically non stop for almost a decade."
"I have 2 Winix HEPAs that have been running 24/7 for 6+ years."

"Most air filters only get down to 0.3 microns; these get down to 0.003 microns, which captures mold - which is my main concern - as well as viruses, bacteria, etc."

"I had a Levoit Core 300 that developed a fan whine after a year. ... Went through the RMA process and they sent me a new one, which developed the same noise within a few months."
"We have 2 levoits and even on 1 I can hear it across the room with the TV on. ... They both have an ear-piercing high pitched sound that I can't stand."
"Levoit Core 300 was decent on specs, but it hummed just enough to wake the youngest every other night."

"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 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."

"The 850, however, has very little carbon. It can only mitigate the smallest odors - and only for a very short time if at all. ... But the 850 in particular is a budget round unit - they are well known for having almost zero carbon, poor pre-filtration, and no ability to upgrade."
"The Winix 5510 is just the newer version of the 5300. The biggest difference is that the 5300 uses a fibrous carbon filter while the 5510 uses a higher quality pellet charcoal filter. As I’ve already said previously, none of these consumer-grade activated charcoal/carbon filters are actually effective for more than a week or so."
"winix does the same…pre filter, carbon filter, hepa filter….I still had to change the carbon and hepa every six months."

"PlasmaWave is just a glorified ionizer. I personally cannot stand the scent of ionizers, it gives me headaches. ... Anything with an ionizer gives me headaches because of the ozone they produce."
"I would run the Winix with the ionizer off, idk if the slight increase in ozone exposure would be harmful."
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 ->I have the Winix. No issues to date. I don’t use the plasma wave feature.
r/AirQuality • Can someone help me decide between these two purifiers please? ->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 ->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? ->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.
