Filter King AF24x30x0.5-M13 Merv 13 Air Filter 24x30x0.5

Product Description

The FILTER KING AF24x30x0.5-M13 is a MERV 13 pleated air filter designed for residential and light commercial HVAC systems. With a nominal size of 24x30x0.5 inches and an actual size of 23.5x29.5x0.5 inches, this thin-profile filter fits return-air grilles and air handlers where half-inch filter slots are specified. At MERV 13, it captures fine particulates including dust, pollen, mold spores, pet dander, and fine particles associated with smoke and smog. This rating balances high filtration efficiency with acceptable static pressure for most residential forced-air systems. Sold in a quantity of 10 per order.

This filter is suited for residential forced-air heating and cooling systems, including gas furnaces, heat pumps, and central air conditioning units that use a 24x30x0.5-inch filter slot. The 0.5-inch thickness is a less common profile, so it is typically found in specific return-air grille assemblies or air handler cabinets designed for slim-profile media. MERV 13 performance makes it a strong choice for households with allergy or asthma concerns, as well as light commercial settings requiring enhanced indoor air quality without a thicker media cabinet.

Key Features

• MERV 13 filtration rating captures fine particulates including smoke, smog, and fine dust particles
• Nominal size 24x30x0.5 inches fits slim-profile filter slots in select air handlers and return grilles
• Actual size 23.5x29.5x0.5 inches for accurate fitment verification before installation
• Pleated media design increases surface area for improved dust-holding capacity and extended service life
• Sold in a pack of 10, reducing per-filter cost and supporting scheduled maintenance intervals

Compatibility

Designed as an OEM-style replacement pleated air filter for forced-air HVAC systems requiring a nominal 24x30x0.5-inch, MERV 13-rated filter. Verify the actual filter slot dimensions against the stated actual size of 23.5x29.5x0.5 inches before installation.

Installation Notes

Air filter replacement is a routine maintenance task performed by HVAC technicians or qualified building maintenance personnel, though many end users perform this themselves. Always shut down the air handler or furnace at the system switch or thermostat before removing the old filter to prevent unfiltered air bypass. Insert the new filter with the airflow direction arrow on the frame pointing toward the blower, away from the return-air duct. Replace this filter on a schedule appropriate to the site conditions and system runtime, typically every one to three months at MERV 13 efficiency levels.
