Each filter is built to an actual size of 19.68\" x 19.68\" x 0.75\" to fit common 20x20x1 slots, and uses electrostatically charged media and a single-piece recycled cardboard frame for reliable performance and reduced environmental waste. The media rates MERV 13—comparable to MPR 1500\/1900 and FPR 10—making it suitable for homeowners seeking stronger capture of fine particles without sacrificing system efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this filter improve indoor air quality?\u003c\/h3\u003e\n\u003cp\u003eThe MERV 13-rated media captures a wide range of airborne particles, including pollen, pet dander, dust, smoke and many microscopic carriers that lower-rated filters miss. Electrostatic charge helps attract and hold tiny particles while the design maintains low airflow resistance so HVAC systems run efficiently.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRemoves up to 98% of targeted airborne particles in its rating range\u003c\/li\u003e\n  \u003cli\u003eElectrostatically charged fibers enhance capture of fine particulates\u003c\/li\u003e\n  \u003cli\u003eCompatible with most residential furnaces and air conditioners sized for 20x20x1\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it fit my HVAC system and how is the actual size measured?\u003c\/h3\u003e\n\u003cp\u003eAlthough commonly labeled 20x20x1, BNX lists the true dimensions as 19.68\" x 19.68\" x 0.75\" to reflect the real filter thickness and ensure a proper fit in standard frames.
