Practical Pleat 5" thick pleated filters are designed to replace your 1" return grille filter, with no modifications to the grille required. Simply remove your old filter, and slide the Practical Pleat into place!

The Practical Pleat has 433% greater surface area than typical 1" pleated filters. This has several benefits:

Low Pressure Drop 
  • The Practical Pleat's large surface area means low resistance to airflow, and low pressure drop when the fan motor starts and runs
Long Lasting
  • Each Practical Pleat lasts up to 6 operating months
    Saves Energy
    • Low resistance to airflow means less strain on the fan motor and less energy usage
    Reduces Air Noise 
    • Low airflow resistance can quiet noise at the air intake 
    28X Increased Filtering Efficiency 
    • Removes smaller particles from the air than standard fiberglass and lower MERV rated filters, while providing greater airflow at the same time
    Eliminates Filter Bypass
    • Gasket provides a seal between the filter and grille frame, preventing dust from bypassing the filter
