The typical furnace filter removes less than 20% of pollutants.

Aprilaire High Efficiency Air Cleaners are up to 99% effective at removing particles you can't even see from the air your family breathes.

Aprilaire cleaners get better over time and can clean continuously when you turn your thermostat fan setting to the "on" position.

Aprilaire filtering media actually works better as it collects particles.
