C610

I have two of these (c610) about 2 years, just upgraded to larger units and moved them to the smaller rooms. They did help with allergies, they don't seem to touch smells. With that being said, the larger units do more at least for us so the c909 may be better depending on room size and your goals.

I have just now had my second c610 fail just under the two year mark.get it from Costco for the longer warranty while it's on sale if you can. Customer support with winix was relatively painless to deal with. I know several others with the unit and one other with a failed unit. It's pretty quiet on all but turbo. Turbo sounds like a jet engine.

Interesting, I have not had much of a smell from that one but many brands do bother me, I haven't bought a filter recently so it could have changed though.

I have a winix 610 from Costco, not quite the same as what you are asking, but If I unplug and move it to a different room, when I plug it back in it comes on automatically at the same setting it was last at. It does connect to the app/wifi

I just don't for sure know if it's the same for like a power outage or extended period of time being off. I have only unplugged it and took to a different room or some such and it always comes back on right away with the same settings it was left on.

I just purchased a coway 400 and a levoit Everestair. Have had 2 winix for about two years, Honeywell and germ guardian before that. The coway feels and looks the most premium the coway and levoit both seem nicer upon initial impressions than any of the others but I have only had a few days. One of my winix motor broke about a year and a half in but people generally seem to have good experience with them? The levoit app is really nice and I already had levoit items if you like that sort of option. I bought the levoit for that purpose and the coway because it was on a good sale and recommended by so many. It's kinda loud and annoying pitch to the motor though that's probably going to vary per person

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.

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.

I'm very sensitive to smells, and the smell of most new HEPA filters make me feel sick and lightheaded when I run the machine. I've not had this issue with my Bissell air purifiers, but they have been discontinued and you can't get the filters any more. I've tried a Coway and Winix so far and the HEPA filter in both has such a strong smell I can't tolerate it. I tried airing out the Coway filter for a few days and while it improved the smell was still too strong. I ran the purifiers without the filters and didn't have an issue, so I know it's the HEPA filters themselves, likely a glue or something that is used to make them that I'm sensitive to. I have a Winix from costco I'm currently running outside to see if that can help, but so far it still smells too strong. Does anyone know any purifier brands that use filters that don't have a strong odor, or use different materials? I've googled this question and looked it up on reddit, and while it seems like I'm not the only one with this problem I haven't seen any reliable brand suggestions. I mostly need something for pollen allergies, dust and cat allergies (I have asthma) and would be open to non-HEPA filters if I can get most of the benefits without feeling sick. I'm in the US and it can be for any room size. No budget. Thanks!

The C610. It's the cylindrical one.

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.) 

Same I have a bunch of c545 and 610 and never log into the app.

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. 

I like the Winix refurbs, they look new to me. https://winixstaging.mystagingwebsite.com/product-category/certified-refurbished-air-purifiers/
