Bsc Preferred 9801-4 Air Filter 16x25x1 Mpr 1000

Product Description

The BSC PREFERRED 9801-4 is a 16 x 25 x 1 inch electrostatically charged air filter rated at MPR 1000, designed for residential forced-air HVAC systems. The electrostatic media captures large allergens such as mold spores and pet dander at approximately 90% efficiency, while also trapping microscopic particles including dust, smoke, smog, and bacteria-carrying virus particles. The filter carries an MPR 1000 rating, placing it in the mid-to-high range for residential panel filters. Rated for up to 3 months of service life under normal operating conditions, it is a direct drop-in replacement for standard 1-inch filter applications.

This filter is suited for residential central air and heating systems that accept a 1-inch panel filter in a 16 x 25 inch nominal slot. Typical installations include single-family homes and light commercial spaces where occupant air quality is a priority, particularly in environments with pets, smokers, or allergy-sensitive occupants. The filter meets the guidelines of the American Lung Association Health House Program, making it appropriate for applications where indoor air quality standards matter. Licensed HVAC technicians and property maintenance professionals commonly specify this filter for routine seasonal replacements.

Installation Notes

Always shut down the air handler or furnace at the disconnect or thermostat before removing the existing filter. Note airflow direction arrows on the filter frame and align them with the direction of airflow toward the blower. Inspect the filter housing for bypass gaps or damaged tracks before seating the new filter. Dispose of the used filter in accordance with local waste guidelines, as the unit is classified as a hazardous material per supplier safety data.
