About This Item
The 20x24x1 filter is engineered to capture countless microparticles such as pet dander, smoke, smog, bacteria, and up to roughly 54% of small virus‑carrying particles, while also grabbing larger debris like lint, dust, pollen, mold spores, and dust‑mite matter. Intended as a 3‑month residential filter, it fits standard 1‑inch filter slots and provides a strong upgrade over fiberglass or basic washable filters when changed on schedule.
