You also can choose the air filters with hypoallergenic and microbial features. If you have family members who are allergic to pet dander or mold, it is an ideal choice. You’d better consider active carbon air filters if you think the odor is more important than allergies, this air filter just has one carbon air filter, which can capture odor particles and draw them into the carbon material. You may meet furnace filters that are “allergy filters”, which refers to air filters that MERV ratings over 8, not the air filters with special design.  

MERV rating


It is essential for us to check the furnace air filter’s MERV rating. MERV rating represents Minimum Efficiency Reporting Values. It represents the working efficiency of the air filter and the type of particles that it can capture.

You need furnace air filters with a MERV rating from 8-13 if you are allergic to pet dander. Furnace filters with a MERV rating over 8 can purify pet dander in the air effectively. Generally, MERV 8 furnace air filters can eliminate 85% of large particles in the air, and 50% of small particles, the higher the MERV rating, filters better, but we don’t recommend furnace filters with over MERV 13. A furnace filter can filter 95% of large particles in the air and 80% of small particles without the issue of airflow.

Normally you have to change your furnace air filter every three months, but it’s not enough if you have pets.
