Air-Care 20x20x1 Electrostatic Washable Permanent A/C Air Furnace Filter

$149.99

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. Our permanent electrostatic air filters feature a low 0.12 WG air resistance rating. If you clean our filters regularly (every 30-60 days), they will clean your air AND protect your air handler.

These quality filters are built to last a lifetime. They are interchangeable with 1" disposable filters and can be used again and again. The secret behind the filter's performance is its patented stage loading/peak and valley design. Instead of face loading (particles captured on the outer surface of the filter) the filter uses stage loading, with each stage capturing progressively smaller particles inside the filter. This design enables the filter to maintain its performance over the years. Unlike some permanent air filters, the filter uses no foam that may clog, degrade and restrict air flow, so it can provide a lifetime of dependable service.
