Kotru MERV 13 Air Filter 20x20x1 (Actual 19.5x19.5x0.75) – 4-Pack Electrostatic Pleated HVAC Filters

Enhanced filtration for your home

Meet Kotru’s 20x20x1 air filter, engineered for elevated filtration in homes and small offices. With a MERV 13 rating and an MPR 1900 level, this pleated media targets common indoor irritants such as dust, pollen, and pet dander. While not a medical device, the high‑efficiency media may contribute to a perception of cleaner air and reduced surface dust in living spaces.

Built with electrostatic pleated technology, the media attracts and traps microscopic particles with magnetic-like efficiency. The 18 pleats per foot design expands the filtration surface area, helping maintain steady airflow while delivering strong filtration performance across typical HVAC systems. The result is a balance between effective filtration and reliable airflow, even during busier seasons.

Fit, durability, and value

Designed for standard 20x20x1 slots, the actual size is 19.5 x 19.5 x 0.75 inches. A rigid, collapse‑resistant frame helps prevent deformation, supporting consistent performance over time. Compatible with furnaces, air conditioners, heat pumps, and most HVAC setups, it’s built for dependable operation through multiple filter cycles.
