Filtrete Dust and Pollen Filters 14X20-1

The 3M Filtrete Dust & Pollen Furnace Filter is an electrostatically charged furnace filter ideal for high velocity HVAC systems. 3M Filtrete filters are an economical upgrade from cheap one month filters. The 3M Filtrete Dust & Pollen Filter is far more effective than the average washable or fiberglass disposable hvac air filter, which normally does not even remove dust from the air.
