The Guardian Electrostatic Furnace filter and air conditioning filters are reusable furnace filters that clean the air in your home or office.
The Guardian filters can remove pollutants such as dust, pollen,
and pet hair, and keep your heating or air conditioning system coils cleaner. (The manufacturer claims that this enables you to save up to 15% on your energy bills.) Their airflow resistance is low and does not stress your HVAC unit. Guardian filters do not need an electrical outlet since they do not use electricity.

(Note, the Guardian electrostatic filter should not be confused with the HEPA air purifier manufactured
by Broan-Nutone. They solve very different problems: HEPA air purification systems are more expensive
and filter out much smaller particles.)
