Resideo FC40R1830 18" X 30" X 3" Return Grille Media Air Filter

The Resideo FC40R1830 Return Grille Media Air Filter is a high efficiency air filter that removes particulate matter from the air before it can enter the HVAC system and contaminate the air inside the home. This white filter is 18 inches high, 30 inches long and 3 inches wide; it is convenient for installation in return air grilles and can be used in both home and office. Its deep pleated design provides long lasting performance and enhances dust holding capacity by offering larger surface area. This filter can be used in many HVAC systems because it does not require a return duct and most systems have a return grille.
