The Winix C535 is a long running True HEPA purifier that stands out for durability, strong filtration, and simple operation. The prefilter catches a lot of dust and helps protect the HEPA, and the larger Filter A cartridges are said to last well and often go on sale. The C535 also avoids the C545 WiFi feature, which is described as unnecessary, while matching it on air cleaning, noise, and power use. The main cautions are filter compatibility, since C535 and C545 filters are not interchangeable, and some units can develop motor noise after years of heavy use. A solid pick if you want a proven, no frills purifier with the right filters on hand.

Common Questions (6)

  • It can run for years: one unit has been used almost 24/7 for over 7 years and still works perfectly, and several others have run 27/7 for 6+ years. A reported weak point is the motor, which can start squealing or develop bearing noise after a couple of years or several years of heavy use.

  • No. The C535 uses Filter A/21, while the Costco C545 uses Filter S, and they are not interchangeable. Buyers should match filters by model number before ordering replacements.

  • Yes. Genuine Filter A replacements often go on sale for about $20-$30 for a year supply, and Amazon pricing around $26 per set was cited. Third-party carbon and HEPA replacements are also available.

  • The C535 and C545 are described as having similar air-cleaning performance, fan noise, and power use, but the C545 adds Wi‑Fi. The C535 is also described as better built and more reliable long term, while the C545's Wi‑Fi is called unreliable.

  • The refurbished Walmart option is about $75, but its condition is listed as "fair." A new unit at $109.99 costs about $35 more and avoids the refurb condition risk.

  • New units reportedly include extra filters, but that may not apply to refurb units. The purifier also has a prefilter that catches a lot of debris and helps protect the HEPA filter.

Nope.. got it today.. its brand spanking new ..in a brand new sealed box... trying to attach a picture of it slickdeal not allowing me to . I will be happy to email it though to anyone interested.
What do you mean "nope?" The listing on Walmart you posted says "fair" condition /refurbished. You may have gotten lucky and gotten a "new" one but even as your initial post says, these are "refurbished." Probably should have put YMMV in your post, as when you buy something refurbished like this it's truly YMMV…

This looks like the last Gen version of the 5510. Which the 5510 placed first in project farm testing. But I read a lot of the Amazon reviews that said it didn't hold up even a year. So not sure. Lol

This is same as the older Winix 5300, 5500 models. I own one. One not that uncommon issue is the electric motor ball bearings doesn't last very long. Mine developed grinding sound after several years of use, and I traced it down to the motor bearings. There are guides in the net on how to replace those bearings (need to open the motor). However, it needed special tool and too much trouble for me, so I didn't do it. For $110, it's probably worth a gamble.

Working for me. The 535 is by far the best Winix ever made.
Is the C535 better than the 5510?

I only have the 535s, many of them, all great, all running 27/7 for 6+ years, almost always on high speed manually (not auto) and all running great.

The motor in this will start squealing after a couple of years. I had one running pretty 24x7 but had to replace it due to the noise becoming annoying after awhile.
