About This Item
Indoor air constantly cycles through your return grilles, carrying both visible dust and fine, hard‑to‑see particles. This 14x20x1 Premium Allergen, Bacteria & Virus filter in Filtrete’s 1900 MPR (MERV 13) tier uses electrostatically charged polypropylene media with 3‑in‑1 technology to pull in and trap countless microparticles—such as pet dander, smoke, smog, bacteria, and up to about 72% of airborne virus‑carrying particles.
