Appliance Air Filter Assembly

This air filter assembly replaces part number CMF201130490113 and fits six compatible indoor units from Comfort-Aire and Midea. It is designed for residential split-system air conditioners that use the listed model numbers. Installers and homeowners maintaining those specific units will find the correct fit. Buyers servicing other brands or model series cannot use this filter.

Normal Operation Airflow and Noise

The filter media allows unrestricted airflow during routine cooling cycles so the indoor fan runs at its usual speed and sound level. No additional power draw is introduced because the component is passive and contains no motor or electrical parts. Regular inspection keeps pressure drop low and prevents the evaporator coil from collecting dust. A clogged filter would increase noise and reduce cooling capacity.

Sustained Load Durability

During extended hot-weather periods the filter continues to trap particulates without collapsing or bypassing debris into the coil. Its frame holds shape under continuous suction pressure from the blower. Replacement intervals depend on local air quality and run hours rather than a fixed calendar date. Neglecting long-term replacement lets dust reach the heat exchanger and degrades system efficiency.

Questions about this item

How do I install the CMF12100204000672 air filter assembly in my Comfort-Aire B-SMH09SC, and what step is often missed?

Open the front panel, slide the old filter out, insert the new assembly with the airflow arrow pointing inward, then snap the panel shut — the step most people miss is confirming the arrow direction before closing.

When will the CMF12100204000672 filter need replacement in a Midea MSE-09HRN1-BQ8W?

Replace it every three to six months depending on dust levels; a visible grey coating or reduced airflow from the indoor unit signals it is time.

What is the first limitation that appears when the CMF12100204000672 filter runs continuously in a Comfort-Aire B-SMA09SC?

Dust loading gradually restricts airflow, which reduces cooling capacity and forces the fan motor to work harder until the filter is cleaned or swapped.
