Winix C545 Air Purifier Filter Types

Winix C545 uses a 4-stage air filtration system. In this section, we will cover the air purification process of the Winix C545 air purifiers.

The air filters included in Winix C545 are:

1. Fine Mesh Pre-filter

The washable fine mesh pre-filter catches larger airborne particles like dust particles, hair, fiber, feathers, pet hair, dirt, and pet dander.

The pre-filter needs cleaning every two weeks. You can use a vacuum cleaner or a fine brush. Never use soap or detergent to clean the pre-filter.

2. Activated Carbon Filter

Activated carbon filter reduces and eliminates Volatile Organic Compounds and odors from the air. Volatile Organic Compounds (VOCs) are invisible toxins causing irritation and difficulty in breathing.

Activated carbon filters eliminate household odors from cooking, smoke, pet odors, new equipment, paints, or any unwanted chemical gases. It makes sure that your home always smells fresh and deodorized.

The carbon filter needs replacement every three months

3. True HEPA Filter

The true HEPA filter catches the microscopic pollutants floating in the air. It traps 99.97% of airborne allergens as small as 0.3 microns in size, including mold spores, pollen, allergens, and airborne bacteria.

True HEPA filter needs replacement once a year.

4. Plasmawave Technology

Winix has patented Plasmawave technology, which means no other air cleaners have it. 

Plasmawave meets the most meticulous American certification benchmark for indoor air cleaning.

This technology uses a natural filtration process to destroy viruses and bacteria at the molecular level. Unlike most air purifiers, there is no possibility of them re-entering your airflow.
