‘Worst case scenario, it’s all summer long’: Air quality alert in NYC, as smoky skies seem here to stay

The most common recommendation is the one that Costco has sold for years, the Winix C545. They put it on sale for $100 multiple times per year and sell the replacement filters for cheap. I have it and it’s great. Quiet, has smartphone controls, looks nice, etc.

Air Purifiers how long has yours last?

I’ve had a winix 5500-2 for like 6+ years now. Had a c545 start making a lot of bearing noise around 5 years. But it was a cheap refurbished unit.

Are there any dangers in buying a second hand air purifier?

I purchased a used one once online because mine had died and I had a bunch of replacement filters. (It had been discontinued and I couldn't get a new one) It came caked in nicotine inside and out. Worst decision ever. ETA: check out this Winix C545 unit. It is refurbished for $59.99. I have purchase

Living in a Shared House But Apparently Not Sharing the House

Get an air purifier- a loud one. It’ll drown them out. You’ll get used to the ‘white noise’. Winix C545 is a decent model.

Mila Air - Longtime user. Please Avoid.

I can 2nd this. I actually went through 11 units (purchased 5...rest were warranty units) and all failed. I still have 1 unopened replacement unit and can't be bothered to set it up. I replaced all of mine with refurbished Winix C545 units over 2 years ago and couldn't be happier with that decision.

Please help me not waste money

Winix America has the C545 refurbished $59.99. I've purchased these, they always come with new sealed filters and are like new. Never had a single one I'd say looked used. I don't know if there's just an army of CR box people in this subreddit for the past month or so.... I like CR/Corsi Rosenthal B

Large bedroom purifier recommendations

So you prefaced 1,400 square feet as "Room Volume". I assume this is still square feet and not 1,400 cubic feet, the latter actually being volume. Purifiers aren't good at removing visible dust particles as they're large and heavy. See the sticky post at the top of the subreddit and our FAQs wiki pa

Any affordable air purifiers with a legit air quality display that actually changes/responds in real time?

My Winix C545 units turn yellow when my cats take a mega dump (unit located next to a litter box) or red when my neighbor starts smoking (unit located near door). If on Auto, they will crank up to clean the air. I have had 6 of them for 2.5 years and have been very happy with them. I bought them all

Best air purifier under 100$

i did a TON of research a couple days ago about this. i settled on a used/refurbished winix c545 for $60, but the filters are lowk kind of expensive. they sell them in a pack with 4 carbon filters for odors that you switch every 3 months for odors and a filter that lasts a year for $50, which isn’t
