Practical Pleat air filters are 5" thick pleated filters that are designed to fit into standard 1" return grilles, with no modifications to the grille required! The Practical Pleat is designed to give you better air flow, superior MERV 11 filtration efficiency, and longer filter life compared to standard filters. Simply remove your old filter and slide the Practical Pleat into place!

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 compared to standard 1" filters. The Practical Pleat MERV 11 filter achieves a reduction in pressure drop of 41%, .09 in W.G.
  • Easy to Install - simply remove your 1" filter and slide the Practical Pleat in into place and close the grille. The gasket doubles as a lip that holds the Practical Pleat in the grille.
  • 28X Increased Efficiency over standard panel filters
  • 4X Longer Lasting than comparable one-inch filters. The Practical Pleat can last up to 6 months per filter.
  • Gasket Eliminates Filter Bypass and preserves MERV rating.
  • MERV 11 rated according to ASHRAE 52.2 standards.
  • Single Pack - choose your size in the dropdown menu above.

Can Also Save Energy! - The Practical Pleat's increased surface area and greater airflow means less strain on your blower motor and potentially less energy usage when compared to your standard filter. The gasket also helps prevent particles from bypassing the edges of the filter and clogging up your AC system's blower and coil.
