4 Pack C545 Replacement HEPA Filter Compatible with Winix C545 , Ture HPEA Filter S Only, Part number 1712-0096-00

I am very frugal and like to at least vacuum them one time since they are expensive. They work very well and here in AZ it is quite dusty. I wish they were washable or reusable some how.

Have purchased twice. They seem to do their job. Install is easy.

One of the smokiest fire seasons on record and our indoor air was dramatically clearer after installing new filter.

Functional I always order them.

Does what its supposed to do.

Ease of ordering, the correct item, fast.delivery, fits on air purifier, everything is great

Light came on to change air filter so ordered these so I don’t run out again! Work fine and would buy again!

Doesn’t fit as snugly as the filter I removed. Makes me question the quality. Only time will tell!

The product got here on time.

Easy installation perfect fit
