Bnx Trufilter Air Filter

A MERV 13 rating indicates high-efficiency filtration capable of capturing fine particles, including dust, pollen, mold spores, and bacteria. It is significantly more effective at trapping microscopic contaminants than standard lower-rated filters.

Because MERV 13 filters are denser to capture smaller particles, they can create more resistance than lower-rated filters. Ensure your HVAC system is compatible with high-efficiency filtration to maintain proper airflow and prevent strain on your blower motor.

For optimal performance and to maintain good airflow, it is generally recommended to replace these filters every 90 days. If you have pets, allergies, or live in a dusty environment, you may need to check and replace them more frequently.

Yes, these are designed to fit standard 18x18x1 inch filter housings. Always measure your current filter or the slot in your HVAC unit to ensure a proper fit, as actual dimensions can sometimes vary slightly from the nominal size.

Polypropylene is a synthetic material that is more durable and resistant to moisture than traditional fiberglass or paper media. This helps the filter maintain its structural integrity over time without degrading or harboring mold.
