Durafil® ES

The Camfil Durafil® ES is a 4V-style high efficiency air filter in a compact energy efficient design.  Through the use of a wet-laid, mini-pleat design, this filter has the lowest pressure drop and longest service life of any filter in this category.  It has earned an Energy Cost Index (ECI) of five stars which is the highest performance rating available.

Durafil® 2V

The Camfil Durafil 2V is a compact and lightweight filter of similar design to the Durafil ES, but with half the surface area.  In general HVAC situations, it is an upgrade to the Riga Flo box filter.
