BNX TruFilter 20x20x1 Air Filter MERV 11 (6-Pack) – Made in USA, Allergen Defense, Low-Resistance Pleated Media

Overview

Meet BNX TruFilter 20x20x1, a MERV 11 air filter crafted for residential HVAC systems. The filter uses electrostatically charged pleated media to balance effective particle capture with steady airflow, helping your air conditioner or furnace operate efficiently without unnecessary resistance. This model is designed to fit standard 20x20x1 slots while accommodating a slightly smaller actual size for a snug seal. The media is 100 percent synthetic and engineered to trap a broad range of airborne particles as air passes through.

Fit and Filtration

Actual size is 19 11/16 inches by 19 11/16 inches with a 3/4 inch depth, ensuring compatibility with many 20x20x1 cabinets. The electrostatic charge helps attract particles such as dust, pollen, pet dander, odors, and mold spores without crowding airflow. While installation and regular replacement are key, many users report a noticeable difference in air feel within a couple of days, with results varying by environment and usage.

Performance in Practice

Compared with standard fiberglass filters, BNX TruFilter offers stronger filtration with a lower pressure drop thanks to its pleated, electrostatically charged media. The combination aims to keep indoor air cleaner while your HVAC system breathes more easily, contributing to quieter operation in some setups. The filter targets microscopic particles while maintaining steady airflow for everyday comfort.

Sustainability and US-Made

BNX is proudly manufactured in the United States, at a Houston, TX facility registered with the EPA (101638-TX-1). The design uses single-sided, one-piece frame technology to reduce environmental waste and relies on recycled cardboard for the frame. BNX backs its products with a quality promise that emphasizes American manufacturing and modern automated processes aligned with strict safety standards.
