This 14x20x1 filter in Filtrete’s 300 MPR (MERV 5) Basic Dust line uses electrostatically charged synthetic media to attract and capture everyday particles like household dust, lint, and dust‑mite debris as air circulates through your furnace or air conditioner, helping reduce visible buildup on surfaces between cleanings. Sized for common 1‑inch filter slots, it is intended for residential use in furnaces, AC, or HVAC systems.
