About This Item
This 16x25x1 Allergen Defense filter in Filtrete’s 1000 MPR (MERV 11) tier uses electrostatically charged polypropylene media with 3‑in‑1 technology to help capture countless microparticles such as pet dander, smoke and smog, along with larger particles like lint, household dust, pollen, mold spores and dust‑mite debris, giving you a noticeable upgrade over fiberglass while maintaining good airflow when changed on schedule.
