BNX TruFilter 16x20x1 is a MERV 13-rated HVAC air filter designed to trap microscopic particles like pollen, smoke, pet dander, and many airborne contaminants while preserving strong airflow.
This six-pack of BNX TruFilter furnace and air conditioner filters fits systems that accept a 16x20x1 nominal size (actual: 15.68" x 19.68" x 0.75") and is engineered to balance high-efficiency filtration with low resistance to airflow. Manufactured in the USA using a single-piece recyclable frame and electrostatically charged media, these filters aim to reduce airborne irritants without overtaxing your HVAC system. They’re comparable to MPR 1500–1900 and FPR 10 and certified to UL 900 standards.
The BNX TruFilter carries a MERV 13 rating, which targets very small particles down to the sub-micron range. Electrostatic media increases capture efficiency so common household irritants and many fine particles are retained while air continues to circulate efficiently.
Yes—these are nominal 16x20x1 filters with actual dimensions 15.68" x 19.68" x 0.75", designed for most residential HVAC and furnace filter slots that accept that size. The media and frame construction prioritize low airflow resistance to avoid undue strain on fans and maintain system efficiency.
BNX manufactures these filters in Houston, TX using sustainably sourced, recycled cardboard for the frame and advanced electrostatic filter media. The facility and product comply with UL 900 classification and BNX lists an EPA registration, underscoring domestic production controls and quality processes.
MERV 13 media typically requires more frequent inspection than basic fiberglass filters because it captures far more particles; check monthly and replace every 1–3 months depending on household conditions. Compared with fiberglass, BNX’s electrostatic media provides significantly higher capture rates for fine particulates while keeping airflow impact low.
Who is this for: BNX TruFilter 16x20x1 MERV 13 filters suit homeowners and renters seeking stronger airborne-particle control than basic filters provide—especially those with allergies, pets, or concerns about smoke and fine dust. They’re a fit for standard HVAC and furnace systems that accept nominal 16x20x1 filters and for buyers who prefer American-made products with sustainable frame construction and recognized safety classifications. If you want higher filtration efficiency while maintaining system airflow, this six-pack offers an accessible, responsibly produced option.
Q: Are these filters compatible with 16x20x1 housings?
A: Yes. The nominal size is 16x20x1 with actual dimensions 15.68" x 19.68" x 0.75", fitting standard 16x20x1 filter slots.
Q: How long do BNX MERV 13 filters last?
A: Replace every 1–3 months depending on pets, smokers, or allergy sensitivity; inspect monthly for heavy soils.
