OPERATIONAL UPDATES: Please read for updates on IPI's operations (last updated 09/13/2022).
Pleated Air Filters are widely used as final filters or as pre-filters for higher efficiency filters. When used as a pre-filter, they will add substantially to the life of the more expensive high efficiency filters.
IPI Pleated Filters are produced from 100% synthetic engineered media reinforced with expanded metal on the downstream side for strength and rigidity which is then enclosed in a heavy-duty, moisture resistant die cut frame that will not crack, warp or distort under normal operating conditions.
