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 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

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.

OdorLock Update - Dusty
I have a Winix C545 next to each LR. They don't have a lot of carbon, but my odor is really well controlled with the LR, the OdorLock, and the Ammosorb I add to the litter.

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.

Home air purifiers for vaulted ceilings and a cat with asthma?
Winix is great for aftermarket filter options. For rooms we have smaller c545 that are pretty cheap refurbished direct from winix. And then our large valued area we have two c909s one I got from Costco online another I got for refurbished from winix. But stock is hard to come by for the refurbs dire

Recommendations for bedroom purifier?
I have had good success with refurb winix units directly from winix. Used to be a better deal tho as now the c545 refurb is 79.99. For 80 bucks it’s still a good air purifier If you have a Costco membership and can stretch you could always pick up a c909 it’s a lot of air purifier for what your need

Never bought air purifier before. What do you think of this one?
A C909 could work for the Living Room/Dining/Kitchen area, but it's now back up to $199.99 at Costco. You'll have to keep it on "Turbo" for proper CADRs; the second highest airflow speed may be viable too. I measured Turbo at 60 dBA (using the Decibel X Android app) which may be somewhat loud. Yes,

Winix vs Coway? - Which brand is good for my small bedroom.
I have 6 of the Winix C545 units in part because they are smaller in scale and are close to the wall. I even have one on its side under a raised dresser. I've had them for 2.5 years and have been super happy, especially with the wifi scheduling feature which I like. And the mesh pre-filter catches a

30m2 smoker/gaming lounge room
HEPA will struggle to keep up with the smoke, especially if you don't open windows or anything. I'd recommend a dedicated carbon canister filter for the smoke, as well as a HEPA purifier. You'll need way more activated carbon than the single layer that comes with most air purifiers. I do not have re
