16x25x2, Purolator / Air Guard Hi-E 40 Extended Surface Pleated Air Filter, Mechanical MERV 8, (6 Pack)

The Hi-E 40 is a medium efficiency pleated filter, available in 1", 2" or 4" depths and many standard face sizes to accommodate most system requirements. The 100% hydrophobic synthetic media provides nearly 95% average resistance. The Hi-E 40 is effective as a stand-alone filter or prefilter. All Hi-E 40 filters are designed with a consistent pleat shape on predetermined centers causing dirt to collect evenly over the entire surface of the media. Fully utilizing every square inch result in a slow steady rise in resistance for maximum dust holding capacity. In addition to removing dust, pollen, and lint in your living and working space, they will actively find and trap harmful pollutants like mold, preventing allergy and asthma triggers, promoting a healthier, safe environment. Hi-E 40 filters will not rack or warp under normal operating conditions. The Hi-E 40 line has lower resistance levels to aid in your energy savings goals and objectives.
