30/30

• Water resistant cardboard frame

• Conception with girders/crossbars

• Diagonal stiffner stuck to media to keep the spacing of folds, protect and maintain the filter

• Fully supported media bonded onto a wire support grid

• Rounded pleats for a maximum capacity of dust retention and facilitate airflow through the media

• Replaceable filter media

The unique configuration of the 30/30 filter allows it to hold more dirt and last longer. Since the 30/30 frame is made of water-resistant beverage board instead of recycled cardboard, the 30/30 will stand up to the worst conditions an HVAC system will present, with no filter distortion or blowouts.

The 30/30 is a very energy-efficient filter due to its large media area, resulting in a low pressure drop. The 30/30 media is a blend of cotton and polyester and proven to keep a low pressure drop during the filter’s lifetime. The media is backed with a corrosion-resistant wire backing that eliminates distortion of the media pack under high air flow conditions.
