This 14×14 grille includes an integrated filter slot to accommodate a 14x14x1″ air filter (not included). Outer dimensions are 16 5/8″ x 16 5/8″.

Best for households desiring filtration at the return without a separate filter housing. Caution: filters are not included, so additional purchase is required for filtration.
Buying Guide: Key Considerations For Air Return Grills
- Opening Size And Fit: Measure both the duct opening and the wall or ceiling cavity. Choose a grille with outer dimensions that cover the opening with room for mounting hardware.
- Material And Durability: Steel grilles with powder-coated finishes resist corrosion and daily wear. Heavier gauge steel supports longer service life in high-traffic areas.
- Airflow Direction And Slats: Fixed vanes or louvers determine airflow direction. Angled fins can improve efficiency and reduce noise in quiet spaces.
- Damper Availability: Some grilles do not include dampers. If airflow control is important, consider dampers or a separate control solution.
- Filtration Options: Grilles with filter slots enable integrated filtration. Ensure filter size and type match your HVAC system requirements.
- Floor vs Wall/Ceiling: Floor grilles are built for foot traffic and larger openings, while wall/ceiling grilles suit standard returns. Choose based on installation location.
- Maintenance: Removable doors or easy-filter access simplify replacement and cleaning, particularly in high-dust environments.
