Introduction

Failure to replace HEPA Filters in air purifiers can cause dirty and moldy filters. This can result in harmful health effects including chronic illness, allergies, rashes, or other skin issues. This can also cause existing conditions to worsen. In order to maintain health benefits and purified air, it is important to keep up on regular HEPA Filter replacements. Fortunately, a HEPA Filter replacement in the Winix C535 Air Cleaner with PlasmaWave Technology is a simple process. The process consists of removing the cover and screen, vacuuming, and replacing two filters.

Very easy to replace. Breeze.

Alex Parson -

@tackerman Where can I get a replacement air intake screen (the mesh ‘Pre-Filter’?) Mine has a tear in it and I can't find a replacement anywhere online. Thanks!

Aftab Khan -

You can just scotch tape the tear (from two sides) if it is not too big

Anwar Ben Tanfous -

My Winix C535 came with two air filters. This video should only shows one. So is it supposed to have two filters inserted?

Ray Hill -

No, it's likely yours came with an extra replacement filter with the purchase. Their should only be one HEPA filter followed by one carbon filter and then lastly the mesh pre filter screen that locks into place.

JASON UNDERWOOD -

Mine came with an extra filter as well. It is a bonus filter!
