The DF19643 is a high-efficiency, MERV 11 media filter. This means that it removes airborne contaminants down to 0.3 microns in size. That's less than one-millionth of a meter!Â
The filter is made with 100% high-quality hydrophobic (water-repellant) media fibers that will not shred or absorb moisture (preventing mold growth). The frame of the filter is constructed with strong materials designed to prevent the filter from warping or distorting during use, thereby optimizing its performance.
The DF19643 filter is an ideal pre-filter for high-efficiency filters and is perfect for use in offices, retail stores, manufacturing plants, hospitals, hotels, airports, and single and multi-family housing.
