Fully compatible with NEA120 air purifier and Smart WiFi Air Purifier CAF-W36USW. True HEPA filter is ideal for households with children, seniors, pets, allergies, smokers, and asthma sufferers. The NEA-F1 H13 True HEPA filter captures up to 99.97% of particles as small as 0.1 micrometers, including pollen, allergens, lint, household dust, pet dander, smoke, and smog. The NEA-C1 activated carbon pre-filter helps trap larger airborne particles to extend the life of the HEPA filter and reduces unwanted odors from pets, cooking, smoking, wildfire, and harmful VOCs.
