4 Critical Areas of GREEN Performance:

• Energy Savings
• Air Quality
• Waste Reduction
• Environmental Impact

30/30

“30/30®” is the first true MERV 8 (ASHRAE 52.2-2008)
prefilter. The 30/30 has very low initial resistance,
low maintained resistance to airflow, and the lowest
average pressure drop of any MERV 8 filter. It has
earned five stars on the ECI (Energy Cost Index) –
the best-possible performance ranking.

Hi-Flo

Hi-Flo® high-efficiency ASHRAE grade pocket type
air filter incorporates high lofted, air laid micro
fiber glass media for reliable efficiency. Using CMS
(Controlled Media Spacing) technology in the pocket
configuration provides lowest energy use and longest
service life of any bag filter. MERV 11, 13, 14.

Durafil ES (Energy Saver)

Durafil® ES provides high efficiency performance in a
compact, energy-efficient design. Filter uses a wet-laid,
microfine fiber media in a unique pleat-in-pleat V-bank
design with up to 200 sq. ft. of media area. The ES
uses 20-35% less energy than other V-type products.
