"I love my Winix especially the feature that tells me when my dog farted before I even realize it (light turns red)"
"We've loved our various models of Winix found at Costco for bunny cage and litterbox."
"completely neutralized the smell of a bunny cage for almost a week (between changes). Bunny and cat pee are similar, so I bet it would work."

"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."
"My husband and I both suffer from allergies and it definitely helps. ... The tree in our front yard turns my car green with pollen and we have zero issues in the house"
"It wasn't until I upgraded to 2 winix machines that I finally got relief and it was instant."

"Winix makes a quality product. ... I have one that’s run basically non stop for almost a decade."
"My two Winix units are 11 years old with 24/7 use and still going strong!"
"They've been running 24/7 for years now (since COVID when I started caring about air quality) and no issues."

"Fan started rattling after 1 week!"

"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 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."
"A window can be open across the house and my Ninja will notice a drop in AQI and speed up the fan while the winix just continues to blow slow. ... I have noticed if I turn the fan speed up on the winix it will notice the AQI change, but that makes the auto mode useless."

"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."
"I could buy a brand new unit for the price of 3 replacement filters."
"The Winix 5510 uses Filter Q – 1712-0123-00. ... I don't think any other Winix purifiers use Filter Q – 1712-0123-00 currently. ... And given the 5510 is new, there may not be a great incentive for other sellers to offer the filter set right now. ... Therefore you could be stuck ordering directly from Winix for some time—who could easily charge $79.99 (full price) in the future. ... Since Filter Q – 1712-0123-00 is exclusive to the Winix 5510 for now, chances are it will be carried by few retailers and the price will be much higher than Filter A."

"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."
Forgot to mention I don't recommend the new winix 5520 from Amazon over the c909 because it has a louder fan and lower cadr rating for basically the same price.
r/AirPurifiers • Need help choosing the best for allergies! (Prime Day Sale) ->I have winix 5520 its crap, I don't even think its working. Fan started rattling after 1 week! Says brand new but I doubt it is new. They get lots of return. Since I am from Canada returning that crap is a waste of time and energy, they want it back to its original box+another box for shipping I throw away the box and wants me to drop it to the closest Purolator like 30-1 hour away from me and I don't drive LOL. Maybe buy a better brand. Bought from Amazon their main store. Winix(US)
r/AirPurifiers • Does your air purifier really remove odors? ->They are for your health. To remove smell, ventilation is the only option. Air purifiers can only reduce the smell. Check your city's summer air quality and winter air quality, then you can determine from there. Also, a ~$200 Winix one like 5510 or 5520 for each room would be best. All-in-ones are generally not so great.

r/AirPurifiers • Air purifiers for this floor plan with cats (litter in den)? ->I got the winix 5520 for 135. Pretty good deal considering no other place has it for less than 200
r/AirPurifiers • Best prime day deals? ->Our Winix 5520 does a great job on our 1000sqft main floor. 2 pets. Massive reduction in allergy intensity within hours of setup.
r/AirQuality • Best Air Purifier on Amazon? ->Yes, went with the Winix 5520. It’s been great so far
r/AirPurifiers • What’s the best air purifier for pet odors (mainly litter box smells)? ->Winix. I love mine. Returned my dyson and best decision i made. I now own 3 of them
r/AirPurifiers • Air purifier recommendation for severe dust (and pollen) allergies ->I got 2 5520 and 1 5510. Its amazing! Especially with allergies and pets in my house. Breathing has never been better

r/AirPurifiers • Air purifier recommendation for severe dust (and pollen) allergies ->Winix 5520. Its fantastic!!!
r/AirPurifiers • Air purifier recommendations for pet odour ->Not worth it at all, tried it for a week and returned. The “auto” mode turns off the fan entirely because the sensor claims the air is 100% clean which defeats the entire point of an air purifier. Also uses sent pods which just add VOCs to the air. Got the Winix 5520 from Amazon on sale for $150 and night and day better. Fully automated but air is always moving even on sleep mode. Also quicks up to higher speeds quickly when cooking or my dog farts while walking by lol.
r/AirPurifiers • Is the Shark NeverChange Air Purifier Max from Costco worth it? ->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? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
