The PPA INDUSTRIES B1-1620-13-6 is a MERV 13 pleated air filter rated for 90-day service intervals, sold as a 6-pack. Each filter measures 16 x 20 x 1 inches and uses electrostatic filtration media to capture airborne particles including pollen, pet dander, mold spores, bacteria, microscopic allergens, and smoke. MERV 13 performance makes this an appropriate choice for residential and light commercial applications where improved indoor air quality is a priority. HVAC technicians and facility maintenance professionals stock these filters for routine preventive maintenance.
This filter is designed for forced-air HVAC systems in residential and light commercial settings where a 16 x 20 x 1 inch filter slot is specified. The 90-day replacement interval suits standard residential furnaces and air handlers operating under typical occupancy conditions. The 6-pack format supports scheduled filter replacement programs without repeated ordering. Applications include residential split systems, packaged units, and air handlers requiring a 1-inch depth filter.
Designed as a direct-fit replacement for residential and light commercial forced-air systems requiring a 16 x 20 x 1 inch pleated filter with MERV 13 performance.
Filter installation should be performed by a qualified HVAC technician or a knowledgeable owner familiar with their system. Always shut down the air handler or furnace at the thermostat and disconnect power at the disconnect or breaker before replacing the filter. Confirm airflow direction arrows on the filter frame align with system airflow direction before seating the filter. Replace on the 90-day schedule or sooner if the system operates in high-dust or high-occupancy environments.
