‘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.

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

BEST AIR PURIFIER FOR THOSE STRUGGLING WITH ALLERGIES

I like Winix because of the home assistant integration. I have 3 of the C545. It has 4 stages of filtration.

I'll never get over the fact that we have actual rabbits in our house and that sometimes I get to see stuff like this.

I got the Winix C545, it's inexpensive and does a great job with it's 3 filter system. I bought them refurbished off of the Winix website. Definitely worth it for $99 a pop.

Looking for a budget air purifier for a multiple pet home

Winix sells C545 models refurbished on their website for like $70 but it seems they use cheap bearings for the motor and they go bad in roughly 1-2 years. If you're handy they seem fairly easy to replace but it involves a little soldering.

Air Purifier help

I have the Winix C545 and it works great. I have two conures and two cockatiels and it handles the cockatiel dust well. You have to make sure the PlasmaWave is always turned off as it can be harmful to our birds. Make sure any purifer you get has the ability to turn off the ionizer if it has one.

Very quiet yet high performance purifier advice?

The low airflow speed on a Winix C545 is far too weak to adequately clean a ~400 sq. ft. space with an 8 ft. ceiling (NB: a ceiling higher than 8 ft. would require more cleaning power.) Even when running on its highest airflow speed/setting, the Winix C545 has a top Smoke Clean Air Delivery Rate (CA

Winix C545 Bearings (2021 Build Year)

C545's were known to be clunky and have fan bearing issues. Its partially rumored why Winix always had tons of them as certified refurb. None of my refurbs are bad, but I also think the C545's just feel cheaper overall than the 5500-2/C535 series before it - smaller fans, different quality noise (hi

Would you use a robot air purifier that moves room-to-room automatically?

The roi was around 37 years not adjusting for inflation. from economical point that energy and a bunch of winix c545 will shy in from of cost of a moving air purifier. Not to mention cost of said repair of such a thing, and its energy of
