The Garrison GAR-P6100-1620 Polarized Air Filter is a high-efficiency, electrostatic HVAC filter designed to capture microscopic airborne particles such as dust, pollen, smoke, and pet dander. Measuring 16" x 20" x 1", this polarized filter enhances indoor air quality by using a safe, low-voltage charge to attract and trap contaminants more effectively than standard fiberglass filters. Ideal for residential or light commercial use, it supports healthier air circulation and can help extend HVAC system life by reducing buildup in ducts and equipment.
