Filterbuy 30x32x2 MERV 11 Allergen Defense Air Filters (5-Pack)

Measurement System and MERV Ratings Explained The Minimum Efficiency Reporting Value (MERV) is a scale that rates the ability of air filters to trap particles, ranging from 1 to 20 (with 20 capturing the smallest microns). This helps consumers understand the filtration effectiveness and choose the right option for their needs.

Choosing the Right Filter Size When selecting a replacement air filter, pay attention to both the nominal size (the rounded measurement) and the actual size (the precise dimensions). Measure your current filter to find the right match for your HVAC system.
