Description
Product Overview
Filterbuy’s 20x20x1 MERV 13 air filter is engineered for superior indoor air quality in both home and light‑commercial environments. Constructed from a blend of aluminum, plastic, and polypropylene, the filter features an electrostatic pleated media that captures up to 98% of airborne particles, including dust, pollen, pet dander, and smoke. The actual dimensions of 19.50 x 19.50 x 0.75 inches ensure a precise fit for standard 20x20x1 HVAC openings, while the blue‑colored frame provides a visual cue for easy identification during replacement cycles.
The filter’s 16 pleats per foot increase surface area, allowing for higher particle retention without restricting airflow. This balance of filtration efficiency and airflow preservation helps maintain system performance, reduces strain on fans, and can lead to lower energy consumption over time. Each pack contains four identical filters, offering a convenient, cost‑effective solution for quarterly replacements.
