"I love mine because it's not as noisy as the cheaper brands ... I run it on it's highest setting when I'm not in the room, and it's second highest setting when I am close to it."
"when it is on it’s second highest setting (still moving quite a lot of air) it is so quiet that we keep getting up to check that it’s on."
"I have both and like this one better. The C909 is louder on low-high but about the same on turbo."

"We've loved our various models of Winix found at Costco for bunny cage and litterbox."
"I love my Winix especially the feature that tells me when my dog farted before I even realize it (light turns red)"
"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."

"One did get the annoying whining noise after a few weeks so I returned it and bought another"
"the 5500 is quieter and has a better sounding hum"
"The downside to Winix and Coway is that they are loud on the higher settings, so you want to get a more powerful unit than you need for your spaces so that you can run them on a lower speed."

"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."
"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."

"Trashed within the year"
"I could buy a brand new unit for the price of 3 replacement filters."
"winix does the same…pre filter, carbon filter, hepa filter….I still had to change the carbon and hepa every six months."

"Both of my Winix air purifiers started smelling like smoke"
"Winix uses ionizers, which you don’t want, so if you go with a Winix you want to make sure you can switch it off."
BlueJeanBaby04 1.0I have 3 and I think they work well. One did get the annoying whining noise after a few weeks so I returned it and bought another, so far so good with the replacement.
I have both and like this one better. The C909 is louder on low-high but about the same on turbo. You also can't turn the indicator lights off on the C909.
This one was $100 on sale and is supposedly rated for more Sq ft than the 535. I also have a C909 which is bigger and uses the same filters as yours but I personally prefer the 610.
butterscotchwhip 1.0Happy with my Winix. I look at the app every now and then and see that it ramps up after cooking, seems to be working well.
Winix C610. Bought in Canada Costco, but here’s the [US link](https://www.costco.com/winix-c610-4-stage-true-hepa-air-purifier-with-wi-fi-and-additional-filter.product.4000295784.html?COSTID=iosapp_deeplink_25.4.5&TRACKING=NO&sh=true&nf=true) for it.
Calm-Neighborhood631 1.0We use Winix from Costco but turn off the plasma wave. They now have a child lock feature too which is nice. Honestly we rarely have dust in our house and it’s such a noticeable difference when we travel or visit family so I truly think they work so well! They’re around $100 but we have multiple throughout the house. We used to have a larger one but tbh it was much louder than the multiple small ones.
C610. The only thing is that’s a “Costco” model I believe. I think Costco always sells things slightly different than what the manufacturer sells elsewhere (sometimes it means it just comes with an extra filter or one less feature etc) but I’m pretty sure you’ll only find it at Costco with those model numbers!
chipmux 1.0Winix c610 at costco for $99 Which includes extra filter. So you are good for 2 years
Extension-Meal-7869 1.0I'm on mobile browser so it's hard to link so I'll just tell ya! We have the C535 for all the common areas, and the C610 in all our bedrooms. Then for the bathrooms and pantry we use the LEVOIT Mini Cores (I like these for small areas, but I have to change the filters more frequently.)
Ispithotfireson 1.0Been a big fan of Winix and there are some good air quality test videos on YouTube. Some bad ones too such as some weirdo talking about ozone, but another video proved they do not generate measurable ozone. I have 4 different models. Costco had a great deal on the C610 a few months ago, $100 and you got 2 filters and 2 year warranty. The cylinder style seem to move the most air, but the box ones especially with the granular carbon filters seem to be the best. The C610 has a thin carbon layer, but seems to work very well.
luckkydreamer13 1.0I have both. The 610 is smaller and looks better but the 5500 is quieter and has a better sounding hum and is easier to clean the pre filter
MainStreetRoad 1.0I like the Winix refurbs, they look new to me. https://winixstaging.mystagingwebsite.com/product-category/certified-refurbished-air-purifiers/
mdtroyer 1.0Winix 610 has been great for us
nana7og 1.0I have a Winix air purifier that I bought from Costco (Winix C610) it’s sort of loud when running at full full speed, but when it is on it’s second highest setting (still moving quite a lot of air) it is so quiet that we keep getting up to check that it’s on. We keep it on at all times and move it to the main room when we have guests over. I can’t recommend Winix enough, my family has used their air purifiers for years.
