The KOCH FILTER 24X36X1NM is a disposable air filter built for large-format HVAC applications where a non-metal frame is required. Measuring 24 inches by 36 inches by 1 inch, this filter fits oversized filter banks common in commercial air handlers, rooftop units, and large residential systems. The non-metal frame construction resists moisture-related corrosion and is well-suited for humid or corrosive air streams. Licensed HVAC technicians and facility maintenance professionals install this filter as part of routine preventive maintenance schedules to maintain acceptable indoor air quality and protect downstream HVAC equipment.
This filter is intended for use in HVAC systems requiring a 24 x 36 x 1 inch filter slot with a non-metal frame housing. Typical applications include commercial air handling units, large rooftop package units, and multi-zone systems where filter size exceeds standard residential dimensions. The non-metal frame makes it suitable for installations where metal frames may corrode due to humidity or chemical exposure in the airstream.
Designed as an OEM-style replacement or standard-fit filter for HVAC systems requiring a 24 x 36 x 1 inch non-metal frame disposable air filter.
Installation should be performed by a qualified HVAC technician following local mechanical codes and the equipment manufacturer guidelines. Always shut down the air handling unit and lock out power before opening the filter access panel. Confirm airflow direction arrows on the filter frame align with the system airflow direction before securing the access door. Dispose of the used filter in accordance with facility waste management procedures.
