Awesome, I've been waiting for this deal to happen again at Costco.

Some electric utilities have rebates for energy efficient air cleaners. For example, Silicon Valley Power (Santa Clara, CA) has a $75 rebate on up to 3 units, and this Winix C545 model is on the Energy Star list [energystar.gov] with >150cfm so it qualifies for the full $75 rebate each: https://www.siliconvalleypower.co...t?id=41992

That's a net cost of just $25 per air purifier!
I have had this since the last sale

Filters are hard to get cheap, not a lot of 3rd party, though compatible with different version I think S, if this is S then maybe C , cant keep them straight
I hate that it has no remote, and you cant add a remote, only option is to use app
No auto off after specific time
Given COVID , I wish I had one with a UV light
Note that 3rd party filters were hard to find last year (Type S), but now there are many offerings:

Ugh, I just bought 3x of the C535 a couple weeks ago for $120 each. Always a better deal after I jump. Besides the app remote, what's the difference between the two?

Also this thing doesn't turn itself back on after a power outage... Minor but irritating.

You can the app to control the schedule. The 545 has wifi. I have one and it's very convenient.

This uses the same filters as the C535?

Looking at the Winix series of room air filters, it looks like they started with a well engineered product, and then the marketing folks took over to milk as much money from consumers as possible. So the newer models use an app, and the filter media isn't compatible with previous models.

Damn marketing department.

How long will it run before it needs a new filter?
