Buying Guide
What should you consider when selecting 24x24x1 filters?
- Filtration level: Choose MERV 8 for general use or MERV 11+ for allergies and pets. Higher numbers capture smaller particles but may slightly affect airflow in older systems.
- Media type: Pleated media with electrostatic charge tends to trap more particles than fiberglass. Look for statements about longevity and replacement cycles.
- Actual size and fit: Check the actual size (usually slightly smaller than nominal) to ensure a snug fit in your HVAC frame.
- Replacement interval: Most 1-inch filters are recommended every 30–90 days. If you have pets or high dust, replace more frequently.
- Made in USA or brand reliability: Some buyers prefer filters manufactured in the USA for material quality and supply consistency.
How to choose by scenario
- Allergies or pets: Prefer MERV 11 or higher and filters designed for pet dander.
- Budget and multi-unit homes: Consider 4-pack or 6-pack bundles to lower per-unit cost.
- Older HVAC systems: Ensure the filter depth and airflow resistance suit your unit’s design to avoid restricting airflow.
