16×25×1 Washable AC and Furnace Air Filter Replacement – MERV 4, 1-Pack

The IAQ Filter Store MERV 4 washable filter is built to last a lifetime and suited for the eco-friendly family who cares about the air they breathe.


Interchangeable with traditional 1" disposable fiberglass or pleated air and furnace filters, our washable filters can be used again and again. Our patented stage loading/peak and valley design allows your filter to capture particles from the outside in. Manufactured with multiple layers of washable media, each layer is designed to capture progressively smaller particles as the air passes through the filter. Our eco-friendly design requires no foam or spray adhesives that may clog, degrade and restrict air flow.
