What is the actual size of a 20X20X5 filter?

Standard 20×25×1 filters measure about 19.5" × 24.5" × 0.75". This industry norm ensures a snug fit in 20×25×1 openings.

Which MERV should I choose for allergies or pets?

Choose MERV 11 for homes with pets or allergies. Use MERV 13 for maximum fine-particle reduction if your system supports it. MERV 8 is best for basic dust control and strongest airflow.

Will MERV 13 restrict airflow?

Many modern systems handle MERV 13, but older units or undersized returns may not. If unsure, start with MERV 11 or consult an HVAC technician.
