Buying Guide
What to measure and how to choose:
- Measure wall or ceiling opening precisely. The listed size should match the opening; outer dimensions differ to ensure coverage. If your opening is 20″ W x 30″ H, choose a 20×30 size option.
- Consider filter type and thickness. Most options support 1″ thick filters; confirm filter compatibility (not all include filters).
- Material choices matter. Steel offers rugged durability; aluminum provides lighter weight and corrosion resistance. Powder-coated finishes improve longevity and appearance.
- Door or latch design affects maintenance. Removable doors with hid hinges simplify filter changes; plastic latches can be easier for casual DIY installations but may wear with frequent use.
- Airflow design impacts performance. Eggcrate grids maximize airflow but may be more noticeable visually; angled fin or curved designs can reduce noise while preserving intake.
- Ceiling vs. wall mounting. Some models advise against ceiling use due to sagging; verify mounting orientation and support in your space.
