## Description

Replaces 20x28x1 sized disposable filters. The actual size of this filter is 19-3/4x27-3/4x7/8. These filters retail elsewhere for $69.99-$99.99. Your satisfaction is 100% guaranteed! These permanent, washable air filters remove up to 95% of airborne allergens and contaminants and feature low air resistance. Be Careful! Not all electrostatic filters are the same! It is very important that air filters have LOW AIR RESISTANCE so they don't make your central air unit work harder. This can lead to higher energy bills and eventual damage to your HVAC unit. Tired of having to remember to buy that furnace filter every 3 months? Tired of your house being dusty? Replace your disposable air filter with a washable electrostatic filter. It traps more dust and allergens, has a durable metal frame and comes with a warranty or your money back. To wash the filter, please spray it with a low pressure hose and put it on shower mode. Spray our special cleaner all over the filter to allow the dirt particles to detach from the filter, then spray again the filter with clear water. Allow drying for 15 minutes and reinstall it into the furnace again.
