    True HEPA Filters

    The included True HEPA filter captures 99.97% of airborne particles*, such as allergens, dust, lint, mould spores, bacteria, viruses and pet dander. Plus, every filter is electrostatically engineered to pull in and trap microscopic airborne particles.

*As small as 0.3 microns from the air passing through the filter media. Initial efficiency value.
