The Aerostar SL utilizes a robust, corrosion and mold resistant galvanized steel frame together with our proven thread separator technology. The SL meets your high efficiency filter needs while providing exceptional filter integrity and consistent performance even under the most adverse operating conditions.


The Aerostar SL is a cost effective solution to IAQ problems allowing filter efficiency upgrades without costly modification to existing HVAC hardware.

The compact 4 design requires less handling, shipping, storage and disposal. The SL virtually eliminates frame and media collapse under adverse conditions such as high humidity, high temperature, fan shutdown, variable air volume and turbulent air flow situations. And, our minipleat technology improves filtration efficiency without an unacceptable energy penalty.


Replace low efficiency filters in any application especially in tough operating environments. Use in health care, commercial building, educational, industrial and commercial applications to replace bulky bag and box style filters. The Aerostar SL available in ASHRAE 65%, 85% and 95% efficiencies can also be used as a pre-filter for high efficiency applications or a final filter in HVAC systems.

Use in OEM applications for portable air cleaning equipment and in new air handling units to reduce space requirements without sacrificing clean air.
