Practical Pleat 5" thick pleated filters are designed to fit into standard 1" return filter grilles, with no modifications to the grille required! Simply remove your old 1" filter, and slide the Practical Pleat into place!
MERV 14 removes contaminants such as virus carriers, tobacco smoke, proplet nuclei, lead dust, auto emissions, milled flour, mold spores, hair spray, cement dust, carpet fibers, spray paint dust, animal dander, pollen, and more (see test report below).
28XIncreased Efficiency over standard fiberglass panel filters
4XLongerLasting than comparable one inch pleated filters, each Practical Pleat can last up to 6 months
Eliminates Filter Bypass and preserves MERV rating with the included gasket
MERV ratings according to ASHRAE 52.2 standards
Low Pressure Drop - Since the Practical Pleat surface area is 433% greater than a comparable one-inch pleated filter, there is less resistance to air flow. The Practical Pleat MERV 14 filter achieves a reduction of pressure drop of 41%
Can Save Energy - The Practical Pleat increased surface area allows greater airflow, and the gasket does not allow particles to bypass the edges of the filter and clog up your AC system's blower and coil.
