Pro-source PRO19645 Pleated Air Filter 24x24x1 Merv 11

Product Description

The PRO-SOURCE PRO19645 is a wire-backed pleated air filter rated MERV 11, designed for residential and light commercial HVAC applications. The filter measures 24 x 24 x 1 inches nominal (23.5 x 23.5 x 0.875 inches actual) and handles airflow up to 1,500 CFM at a maximum velocity of 500 FPM. Synthetic pleated media backed by a wire grid holds filter shape under load and through the full service life. A beverage board frame provides structural rigidity and resists moisture typical of air handler environments. Licensed HVAC technicians and building maintenance professionals install this filter type as a routine scheduled-maintenance replacement in forced-air systems.

The PRO19645 fits any standard 24 x 24 x 1 inch filter slot in residential and commercial air handlers, furnaces, and fan coil units. MERV 11 efficiency captures particles in the 1 to 3 micron range, making it suitable for facilities that require improved filtration beyond standard MERV 8 panels — including office buildings, light manufacturing spaces, and homes with allergy-sensitive occupants. The filter is rated for continuous operation up to 150 degrees F, which covers standard forced-air system operating temperatures.

Key Features

• MERV 11 synthetic pleated media for improved particulate capture in the 1 to 3 micron range
• Wire-backed construction maintains pleat geometry and prevents media collapse at rated airflow
• Beverage board frame with integrated design provides a secure, gap-free fit in standard filter tracks
• Rated to 1,500 CFM maximum airflow with initial resistance of 0.20 inches w.g. at 300 FPM and 0.28 inches w.g. at 375 FPM
• Maximum operating temperature of 150 degrees F suits standard forced-air HVAC equipment
• UL 900 listed

Compatibility

Designed as a direct replacement for any unit requiring a 24 x 24 x 1 inch nominal pleated air filter. No system-specific or brand-specific restrictions are stated by the manufacturer.

Installation Notes

Filter replacement is performed by HVAC technicians or qualified maintenance personnel. Set the system blower to off and confirm the unit is not calling for heating or cooling before removing the old filter. Note the airflow direction arrow on the filter frame and orient the replacement filter to match. Filters installed in higher-efficiency or variable-speed systems should be checked more frequently to avoid excessive static pressure buildup across the coil.
