BNX Trufilter Air Filter

A MERV 11 rating indicates that these filters are highly effective at capturing smaller particles, including pet dander, pollen, and dust. They offer a significant upgrade over standard fiberglass filters, providing better air quality without restricting the airflow your HVAC system needs to operate efficiently.

No, these are disposable, single-use filters. Once the electrostatic media becomes saturated with dust and allergens, you should replace it with a fresh filter to maintain optimal system performance and air quality.

You should measure your current filter or check the slot on your furnace or air handler. While these are designed for standard residential systems, it is essential to match the exact dimensions of your existing filter to ensure a proper seal and prevent air from bypassing the filter.

While the lifespan depends on your home environment, pets, and usage, we recommend checking your filter every 90 days. If you have multiple pets or suffer from severe allergies, you may find that changing them every 60 days provides better results.

While pleated filters are denser than basic fiberglass options, this BNX filter is engineered to balance high-efficiency filtration with airflow. As long as you replace the filter regularly before it becomes fully clogged, it will help protect your system from dust buildup and maintain efficient operation.
