Long-Life Ultra-Efficiency Box Air Filters


4 Panels	6 Panels	8 Panels

Multiple panels maximize filtering surface area for long service life. These ultra-efficiency air filters capture viruses, fine allergens, and even wildfire smoke and heavy pollution. They have a V-shape design and a rigid frame that withstands fluctuations in airflow, such as those created by variable air volume systems. The more filter panels they have, the more filtering surface they have for a longer service life.

Long-Life High-Efficiency Pleated Panel Air Filters

Tight pleats create a larger surface area than standard pleats for a longer life. These filters trap common allergens such as dander, mold spores, and pollen. High-efficiency filters also balance filtration efficiency and airflow, making them more cost-effective than higher-rated filters. Use them in data centers and other locations that require extra-clean air.

Long-Life HEPA Box Air Filters


Aluminum Frame	Steel Frame

Extend the time between filter changes in areas where you need to control airborne contaminants, such as hospitals and clean rooms. Tight pleats create a larger surface area than standard pleats for a longer life.

For a more affordable alternative to these HEPA filters, consider ultra-efficiency filters. They are made for areas where absolute filtration isn't required.

Aluminum Frame—These filters last longer than our steel-framed filters. The V-shaped panels in the aluminum frame collect more dust, so they need to be changed less often.

Inline Air-Release Valves for Water

Eliminate air pockets without stopping flow—these valves have an internal wire brush that traps air bubbles and discharges them through the top relief port while allowing inline flow from the inlet to the outlet. They are often used to increase efficiency in heating and cooling systems. The vented relief port exhausts discharge directly. Valves have a durable bronze body for a long service life.
