10390 - Genuine OEM FG IAQ Aerostar Series 400 Pleated Filter, 20" x 25" x 2", MERV 8, Standard Capacity

The 10390 Genuine OEM FG IAQ Aerostar Series 400 Pleated Filter is a MERV 8 air filter designed for commercial, industrial, and other HVAC applications requiring effective particle filtration with low airflow resistance. This standard-capacity filter has a nominal size of 20" x 25" x 2" and an actual size of approximately 19-1/2" x 24-1/2" x 1-3/4".

The Aerostar Series 400 uses synthetic filter media and a supporting metal grid designed to help maintain pleat uniformity and filter strength during installation and operation. Its MERV 8 filtration is designed to capture common airborne particles including dust, pollen, mould, and dander while maintaining airflow through the HVAC system.

Appliance Kingdom serves customers across Canada with HVAC and replacement components, making the 10390 a practical option for homeowners, property managers, facility operators, landlords, and HVAC professionals looking for a correctly sized MERV 8 pleated filter.

What Does the 10390 Air Filter Do?

The 10390 filter removes airborne particles from the air passing through an HVAC system. Its pleated media provides substantially more filtration surface area than a basic flat filter while helping maintain airflow through the system.

The Aerostar Series 400 is designed with filter media laminated to an expanded metal grid on the air-exiting side. The support structure helps prevent media fluttering and maintains consistent pleat formation during operation. The moisture-resistant frame is designed to resist warping, cracking, and distortion under normal operating conditions.

Proper filtration is important because accumulated dust and airborne debris can circulate through occupied spaces and collect on HVAC components. Maintaining the correct filter size and filtration rating can help protect HVAC equipment while supporting effective air filtration.

Common Signs Your HVAC Filter Needs Replacement

A dirty or loaded air filter can contribute to:

• Reduced airflow from HVAC supply registers

• Increased dust accumulation

• Reduced heating or cooling performance

• Longer HVAC operating times

• Increased airflow resistance

• Dust accumulation around vents or HVAC components

• Reduced overall HVAC efficiency

Regular filter inspection and replacement are important because a filter becomes increasingly restrictive as it collects airborne particles.

Will Replacing the 10390 Filter Fix My HVAC Problem?

If the existing filter is dirty, clogged, damaged, or excessively restrictive, replacing it with the correctly sized 10390 can restore the intended airflow through the filtration stage.

However, not every HVAC airflow or performance problem is caused by the filter. Issues involving the blower, ductwork, coils, thermostat, or other HVAC components require separate diagnosis.

Before replacing the filter, confirm that your system requires a nominal 20" x 25" x 2" filter and that MERV 8 is appropriate for the application.

Installation Overview

Replacing a pleated HVAC air filter is generally a simple maintenance task and does not normally require specialist installation.

Before installation, switch off the HVAC system if required by the equipment manufacturer. Remove the existing filter, check the dimensions and airflow direction, and install the new filter according to the airflow arrow printed on the filter frame.

Do not force a filter into an incorrectly sized housing. If the filter does not fit correctly or the HVAC system has unusual airflow restrictions, consult an HVAC professional.
