Buying Guide
How do you choose the right 24x24x1 filter?
- Filtration level: Choose MERV 8 for basic dust and pollen; MERV 11 or 13 for higher particle capture.
- Pack size and replacement frequency: Larger packs reduce replacement frequency but consider your budget and storage space.
- Actual size vs. nominal size: Check the actual dimensions (often slightly smaller than 24×24) to ensure a snug fit.
- Airflow and system compatibility: Higher MERV filters may reduce airflow if the HVAC system isn’t sized for them; verify with a professional if needed.
- Allergen and odor concerns: PET dander and mold spores respond well to MERV 11 or higher; consider odor control when pets or smokers are present.
