20x20x5 (4 3/8) Honeywell/Lennox Replacement Furnace Filters MERV 8 Pleated Plus Carbon 4 Pack Drying Racks Auto-restrike feature protects valuable lamps

Auto-restrike feature protects valuable lamps from damaging power interruptions

The internal condensate pump allows you to route collected water upward or horizontally to any drain or collection container

especially when combating tough to control defoliating pests such as worms

resulting in a more neutral cell sap pH which yields increased purple coloration expressed in the plant

20x20x5 (4 3/8) Honeywell/Lennox Replacement Furnace Filters MERV 8 Pleated Plus Carbon 4 Pack Drying Racks Auto-restrike feature protects valuable lampsImportant Note: Almost ALL furnace filters have a different "actual size" than the nominal size printed on the air conditioner filter. It's best if you measure your air filter for the EXACT size and compare it to our "Actual Size" and then you can be sure your A C air filter fits! With the 4" and 5" air filters there is a wider variance between the nominal and actual size depending on the manufacturer. We also carry 4 7 8 and 5 1 4 inch depth filters,
