Daikin-McQuay 1380242 Air Filter

The Daikin-McQuay 1380242 Air Filter is a critical OEM replacement part designed for high-performance HVAC filtration in Daikin wall-mounted and ductless mini-split units. Measuring 13-1/4" x 17", this primary screen element is engineered to maintain static pressure within design specs while capturing airborne particulates that can foul evaporator coils. As a veteran-grade HVAC air filter, it provides the exact fit required for filter replacement in FTXN and Aurora series indoor units, safeguarding internal components from dust buildup and ensuring consistent indoor air quality.

For contractors performing 10,000-hour service intervals, using genuine Daikin parts like the 1380242 prevents the common bypass issues found with generic "cut-to-fit" alternatives. This washable screen allows for recurring maintenance; simply vacuum or wash with mild detergent as part of a standard preventative maintenance schedule. When your Daikin mini-split system requires a high-volume airflow exchange, these central air filters provide the low pressure drop necessary to protect the blower motor and maintain sensible cooling capacity.

• Precise OEM Fit: Guaranteed compatibility with specialized Daikin air handler slots, preventing unfiltered air bypass.
• Enhanced System Longevity: Protects evaporator coils and blower assemblies from debris, maintaining heat transfer efficiency.
• Washable Media: High-density mesh designed for repeated cleaning and long-term situational reuse.
• Optimized Airflow: Engineered for minimal resistance to ensure the hvac system operates at peak SEER ratings.

Is the 1380242 filter compatible with all Daikin wall units?
This specific part number fits a wide range of models including the FTXN and FAA series. Always verify your unit's dimensions (13-1/4" x 17") or check the service manual for the 1380242 part reference before ordering.

How often should this screen filter be cleaned?
In standard residential applications, vacuuming the screen every two weeks is recommended. For high-traffic commercial environments, monthly washing may be necessary to prevent static pressure spikes.

Can I use this filter without the 99A0391 air purifying strip?
Yes, the 1380242 serves as the primary mechanical barrier. While secondary purifying filters (like the 99A0391) fit into the brackets for enhanced filtration, the system will function correctly with the 1380242 alone.
