Winix C545 unboxing and review of the 4-stage air purifier, available at Costco and Amazon

This is the super popular air filter option at Costco, but is it worth it?

So far so good for the purifier, I'll show you what's in the box, how to set up the filters, cleaning the filter, and my review of the product. I've been decently happy with it, it's convenient and you can control it via smartphone app which makes it handy to turn on and off. On Auto mode, it detects light in the room so it stays on during the daytime and turns itself off at night.

Is it one of the best air purifiers? I'm not certain because I haven't tried enough, but it's a great product for the price. Really inexpensive for a well working product. It's been really easy to clean the pre-filter with my Dyson vacuum. Regarding the HEPA filters and carbon filters, they have replacements that are easy to purchase.

Details below for this Costco exclusive product:
