Listing details to confirm
The listing's stated dimensions, 24.5"L x 19.5"W x 1.75"Th, and its separately stated actual size, 19.50 x 24.50 x 1.75 inches, express the same measurements in a different order. Confirm the filter slot's required dimensions before purchase. The claimed 90% dust capture and 615 cfm maximum velocity are listing claims, not independent performance measurements.

Customer feedback describes effective dust capture, easy installation, quality, and value, while fit and airflow experiences are mixed. That matters for a slide-in filter: compare the listed actual dimensions with your slot, and make sure your system is suited to MERV 8. The aggregate ratings lean positive, but ratings alone do not establish performance for a particular HVAC system.

- Customers report effective dust capture and easy installation.
- Customers mention quality, functionality, and value positively.
Mixed feedback
- Some customers report installation difficulties, despite positive ease-of-installation feedback overall.
- Fit and airflow experiences are mixed, with some reporting restricted airflow.
