Fully compatible with Eureka NEA120 air purifier and Toshiba Smart WiFi Air Purifier CAF-W36USW. True HEPA filter is essential for households with children, seniors, pets, allergies, smokers, and asthma sufferers. NEA-F1 H13 True HEPA filter captures up to 99.97% of particles as small as 0.1 micrometre in size from indoor air, including pollen, allergens, lint, household dust, pet dander, smoke, and smog. NEA-C1 activated carbon pre-filter helps trap large airborne particles to prolong the life of the HEPA filter and reduces unwanted odors from pets, cooking, smoking, wildfire, and harmful VOCs. This high-efficiency two-stage True HEPA filtration system is ideal for those with frequent or recurring allergies, effectively capturing most pollen, mold spores, household dust, pet dander, and smoke, helping ensure cleaner, irritant-free air.
