The Guardian electrostatic air cleaner is a revolutionary design in a residential furnace filter. This washable, aluminum frame filter is designed as a permanent replacement to standard pleated, poly and fiberglass throwaway filters.

The Guardian incorporates a series of media weaves that create an electrostatic field when rubbed together. Much like the effect of a sock rubbing across a carpted floor, your furnace's blower (when air is circulating) causes friction between the different layers of the Guardian. This rubbing-together results in an electrostatic field which traps dust particles on the filter media. The Guardian is particularly good at trapping small dust particles.

The Guardian should be cleaned every 2-3 months. Washing the Guardian couldn't be easier. Clean with a gentle detergent in warm water in the tub and spray to rinse. Alternately, it can be put in the dishwasher (don't wash with other dishes) or sprayed on both sides with Fantastic (or a similar product), worked with a gentle brush and rinsed out.

Stop buying expensive, Filtrete and similar disposable filters at $10-$20 each -- the Guardian is the permanent, environmentally friendly lifetime filtration solution.

The Guardian comes with a lifetime warranty from the manufacturer.
