1-inch Koch Replacement for Purolator HE 40 - HVAC AC and Furnace Filters - MERV Rating 8

While Purolator has long been a respected brand at our store, recent policy changes have led to higher minimum production requirements. As a result, it has become challenging for us to continue stocking their products.

But we have great news for you! We are excited to introduce our Koch Filters as the perfect alternative. Proudly made in the USA, Koch Filters meet the high standards of quality and performance you've always valued in our products.
