Frequently Asked Questions
How often should I change furnace filters if I have pets?
For homes with one or two pets, replace pleated filters every 60–90 days. If you have multiple pets, heavy shedding, or household allergy sufferers, check and replace every 30–60 days. Thicker 2–4 inch filters may last longer but still need periodic inspection.
Will a higher MERV filter hurt my furnace?
Higher MERV filters can increase airflow resistance. Most residential systems handle MERV 8–11 safely, but older or undersized furnaces may struggle with very dense filters. Check your HVAC manual or consult an HVAC pro before upgrading to a higher MERV rating.
Why does filter size sometimes differ from the box label?
Many manufacturers list a nominal size. Actual size can be slightly smaller to facilitate fitting in different slots. Always compare your filter slot's measured dimensions to the product's listed actual size to avoid leaks and ensure a snug fit.
