Koch Filter 102-700-021 Pleated Air Filter Merv 8 20x25x2

Product Description

The KOCH FILTER 102-700-021 is a MERV 8 pleated air filter designed for residential and light commercial HVAC systems. With a nominal size of 20x25x2 inches and an actual size of 19.5 x 24.5 x 1.75 inches, it fits standard filter slots without modification. The mechanical MERV 8 filtration media does not rely on electrostatic charge to achieve rated efficiency, meaning performance stays consistent over the filter's service life and does not degrade as the media loads with dust. The double-wall frame construction and moisture-resistant beverage board hold shape under normal duct pressure and humidity conditions. Final resistance is rated at 1 inch water gauge.

This filter is suited for forced-air heating and cooling systems in residential homes, apartments, and light commercial applications where MERV 8 filtration is specified. It is a common choice for systems that require a balance between airflow and particulate capture, filtering dust, pollen, mold spores, and similar mid-range airborne particles. HVAC technicians and facilities maintenance staff typically install it during routine filter replacement or system commissioning.

Key Features

• MERV 8 rated mechanical media — efficiency not dependent on electrostatic charge, remains stable as filter loads
• Low airflow resistance with a final resistance of 1 inch water gauge
• High dust holding capacity extends service intervals
• Sturdy double-wall frame resists collapse under negative duct pressure
• Moisture-resistant beverage board frame holds integrity in humid conditions
• Nominal 20x25x2 inches fits standard residential filter openings

Compatibility

Designed as an OEM-style replacement or standard service filter for residential and light commercial forced-air HVAC systems accepting a 20x25x2 inch nominal filter.

Installation Notes

This filter is installed by HVAC technicians or qualified maintenance personnel. Power down the air handler or furnace before opening the filter access panel. Insert the filter with the airflow arrow on the frame pointing toward the blower. Follow local codes and the equipment manufacturer's recommended filter replacement schedule, typically every 60 to 90 days depending on system load and environmental conditions.
