Breathable Intake

CAL Replacement Filter: 2-Pack


Originally designed for California's IAQ needs, the carbon-coated Breathable Intake Air Filter has the highest air filtration efficiency for central residential heating and air conditioning systems. Rated at MERV-16, which is currently the closest rating to true-HEPA, our filters outperform best-in-class residential air filters in filtering microscopic contaminants (more than 96% efficient @ 0.3 microns), at almost half the pressure drop of the most common filter brands. In other words, healthier and more energy-efficient.
