Enter your filter dimensions to find the correct replacement size. Standard and custom sizes with MERV rating recommendations.
The wrong filter size lets unfiltered air bypass around the edges, while a too-tight filter restricts airflow and strains your blower motor. Measure your existing filter or filter slot to get the exact dimensions.
MERV 8: Basic protection, budget-friendly. MERV 11: Good for homes with pets. MERV 13: Captures allergens and some viruses. Higher MERV = better filtration but more resistance — make sure your system can handle it without high static pressure.
