Filter set CA-509/CA-509D consisting of: Pre-filter, TRUE HEPA Filter, Activated Carbon Filter. (Replacement recommendation: once every 6/8 months)

1. Pre-filter
Captures large dust particles such as lint, hair, and pet dander. The pre-filter extends the lifespan of the TRUE HEPA Filter.

2. Original TRUE HEPA Filter with Nanosilver Coating / HEPA Filter Class H13
The TRUE HEPA Filter captures 99.97% of all airborne particles and allergens such as pet dander, dust mites, pollen, bacteria, and viruses larger than 0.3 micrometers. The nanosilver coating is an antimicrobial agent that eliminates bacteria and viruses and inhibits the growth of mold and odor-causing microbes on the filter's surface.

Activated carbon neutralizes smoke, chemicals, gases, and odors, and prevents the growth of bacteria, viruses, and mold.

Depending on usage, these filters need to be replaced every 6 to 12 months.
