Product Highlights

The Horizon's composite filter combines four filtration layers plus Intelligent Ion Technology to create a five-stage filtration system. Its four-in-one composite filter includes a Pre-Filter, True HEPA Core, Granulated Carbon Filter, and Integrated Cold Catalyst.
Horizon's True HEPA (high-efficiency particulate arrestance) filtration removes 99.97% of particles and allergens, including dust, smoke, pet dander, mold spores, and pollen, larger than 0.3 microns in size from the air that passes through it.
Horizon uses Intelligent Ion Technology to emit negatively charged ions into the air. These negatively charged ions attract and trap positively charged ions, including irritants such as allergens, dust, and bacteria.
