What is the actual size of a 15X25X1 filter?

Standard 15X25X1 filters measure about 14.5" × 24.5" × 0.75". This industry norm ensures a snug fit in 15X25X1 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.
