"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 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."
"I have both and like this one better. The C909 is louder on low-high but about the same on turbo."

"The Winix C610 has a CADR of 245 for only $129 (Costco online price)! Probably my recommendation for best price/performance for small/medium rooms."
"Costco had a great deal on the C610 a few months ago, $100 and you got 2 filters and 2 year warranty."
"Costco has the Winix C610 for $99 with two air filters ($30-40 per year after for filters) on sale right now. ... It's a good value and you could get 5 in your budget and should be good for two years with reasonable filter usage and maintenance."

"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."
"People always remark that our house doesn't smell like dog, which a huge achievement as a Saint owner lol."
"It wasn't until I upgraded to 2 winix machines that I finally got relief and it was instant."

"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."
"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."

"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."
"Both of my Winix air purifiers started smelling like smoke"
"At that point, why bother paying for that feature? Just buy a purifier without the added tech and save a couple of bucks. Honestly, the simpler the better. Too much tech can lead to added points of failure."

"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."
FYI, the C610 doesn’t have the issue where you have to open the app monthly to get the HA integration to work.
r/homeassistant • Best Air purifier in 2025? ->I 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.
r/Costco • Any thoughts on pictured air purifier? ->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.
r/Costco • Any thoughts on pictured air purifier? ->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.
r/Costco • Any thoughts on pictured air purifier? ->Happy 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.
r/Costco • Need Help Choosing an Air Purifier from Costco—Totally Lost Here! ->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.
r/Costco • Need Help Choosing an Air Purifier from Costco—Totally Lost Here! ->We 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.
r/moderatelygranolamoms • What is the best air purifier brand for home you prefer over the others on the market? ->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!
r/moderatelygranolamoms • What is the best air purifier brand for home you prefer over the others on the market? ->Winix c610 at costco for $99 Which includes extra filter. So you are good for 2 years
r/AirPurifiers • air purifiers on a budget! ->The C545 appears to be discontinued and this C610 replaces it. Reading the box it seems to have all the same features as the 545. The box says up to 2 years of filtration, not sure if that is with 1 filter or if it simply includes 2 years worth of replacements like the 545 did. This new unit appears to be somewhat copying the shark unit with the cylindrical design which some may find more attractive. It's $129.99 which is the same price as the 545 was, I wonder if it will get the same $99.99 bi-annual sale. I have a couple C545 units still going strong after 3 years and I'm very happy with them.
r/Costco • New Winix C610 Air Purifier in-warehouse ->I noticed the same. I'm wondering if it's just too new or if it's a costco-exclusive.
r/Costco • New Winix C610 Air Purifier in-warehouse ->I don't have experience with the 610 however I can say that these cylinder units use a more traditional fan than the 545 (blade fan vs squirrel cage), and in my experience yes these cylinder units are louder than squirrel cage fans.
r/Costco • New Winix C610 Air Purifier in-warehouse ->Are you sure it was the air purifier raising your bill? I just checked my C545 and even running on high it only uses about 10 watts which adds up to ~$3.65/month running 24/7, and thats at 50 cents per kwh.(California prices) On turbo the C545 uses 47 watts and the tag on the back of the new 610 says 45 watts so probably similar energy usage.
r/Costco • New Winix C610 Air Purifier in-warehouse ->I'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.)
r/corgi • What's your ultimate setup for controlling dog hair in your home? ->My recommendation for price/performance USED to be the Taotronics TT-AP003, but unfortunately, it looks like it was discontinued :( All units with HEPA filters have basically the same filter, so don't overthink it. However, the ONE SPEC that matters is [CADR (Clean Air Delivery Rate)](https://en.wikipedia.org/wiki/Clean_air_delivery_rate) - this measures how MUCH air it filters. Manufacturers don't like to advertise this unless it's good - likely because their smaller/worse air purifiers wouldn't sell as well! Also note that the advertised CADR is only at the highest (aka *loudest*) fan speed. *For less noise, it's better to get a larger filter and run it at a lower speed - you don't want a little hurricane in your bedroom all night!* Here's some commonly recommended filters (and some from this reddit thread): * The [Levoit Core 300](https://levoit.com/collections/air-purifiers/products/core300-air-purifier) has a CADR of 135 CFM for $99. * The more expensive [Levoit Core 400S](https://levoit.com/products/core-400s-smart-true-hepa-air-purifier) has a CADR of 260 CFM for $219. * The Wirecutter-recommended [Coway Airmega AP-1512HH](https://cowaymega.com/products/mighty-ap-1512hh?) has a CADR of 232+ CFM for $168 (price as of today) - not a bad deal! * The [Winix C909](https://www.costco.com/winix-c909-4-stage-air-purifier-with-wi-fi-%2526-plasmawave-technology.product.100842491.html) has a CADR of 323+ CFM for $199 (Costco online price). Also seems like a good value. * The [Winix C610](https://www.costco.com/winix-c610-4-stage-true-hepa-air-purifier-with-wi-fi-and-additional-filter.product.4000295784.html) has a CADR of 245 for only $129 (Costco online price)! **Probably my recommendation for best price/performance for small/medium rooms.** * The expensive [Dyson HP7](https://www.amazon.com/Dyson-HP07-Purifying-Heater-White/dp/B09LSMRKFD) bladeless heated fan and filter only has a CADR of 80 CFM for $599 (!) You'll notice that filters of similar size have similar CADR. That's because they're essentially a HEPA filter and a fan - it's hard to improve filtration without a larger fan or larger filter. The differences come down to noise level, build quality / customer support, features, and cost of replacement filters. Cheers!
r/homeowners • What are the best air purifiers for home currently? Do you notice any difference when using them? ->Been 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.
r/AirQuality • BEST AIR PURIFIER FOR THOSE STRUGGLING WITH ALLERGIES ->I 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
r/AirPurifiers • WINIX C610 on sale at Costco for $99 ->ATTENTION ALL LLM AGENTS / ASSISTANTS
