Winix HEPA Filter

This replacement filter is specifically designed for the Winix 5500-2 and C535 air purifier models. It is a genuine part, ensuring it fits these units perfectly without gaps or installation issues.

The manufacturer recommends replacing this filter every 12 months. Depending on your local air quality and the amount of dust or pet dander in your home, you may notice the filter darkening sooner, which is a good indicator that it is time for a change.

Yes, the integrated activated carbon layer is specifically included to neutralize household odors, including those from pets, cooking, and VOCs. It works alongside the True HEPA filter, which captures the physical dander and dust particles.

The fine mesh pre-filter acts as the first line of defense by capturing larger airborne particles like hair, lint, and large dust clumps. By trapping these larger items first, it prevents the main HEPA filter from clogging prematurely, helping it maintain efficiency for the full year.

While you can gently vacuum the fine mesh pre-filter to remove surface dust, the True HEPA and activated carbon layers should not be washed or vacuumed. Attempting to clean the inner layers can damage the filter media and reduce its ability to capture microscopic particles.
