The DAFCO 1000417 is a MERV 8 pleated air filter from the Aerostar 400 series, designed for residential and light commercial HVAC applications. Built with 100% synthetic media, it captures common airborne particulates including pollen, mold spores, pet dander, and dust while maintaining low static pressure drop across the filter face. The 18 x 18 x 2 inch nominal size fits a wide range of standard filter housings. This filter is suitable for projects pursuing USGBC-LEED certification credits related to indoor air quality.
The Aerostar 400 is intended for use in forced-air HVAC systems in residential homes, apartments, and light commercial buildings. It installs in standard return-air grilles, filter cabinets, and air handler filter tracks that accept a 2-inch depth filter. The synthetic media construction supports consistent airflow performance across the service life of the filter. Technicians and facility maintenance personnel typically specify this filter where a balance of filtration efficiency and airflow is required.
Designed as an OEM-style replacement pleated air filter for forced-air HVAC systems using a standard 18 x 18 x 2 inch filter slot.
Filter installation should be performed by a qualified HVAC technician or maintenance professional. Always set the system thermostat to the off position and confirm the air handler has powered down before removing or installing any filter. Install with the airflow arrow on the filter frame pointing toward the blower, away from the return air stream. Follow local mechanical codes and the equipment manufacturer guidelines for recommended filter replacement intervals.
