What’s inside count

No surprise here, KOIOS EPI810-A is powered by a 3-in-1 True HEPA filtration. The pre-filter will trap dust, hair, debris while protecting the HEPA filter from being clogged by large particles. In return, the HEPA filter removes 99.97% of fine particles small as 0.3 microns in sizes like dust mites, pet dander, pollen, mold spore, and fungi. The carbon filter neutralizes toxic smoke, fumes, and odors from pets, cigarettes, food, paint, and detergent. The filtration might be on the smaller size, it will perform well as long as it is placed close to the sources. Suitable for babies, elders, people with rhinitis allergy symptoms, and wildfire use.
