Frequently Asked Questions
How often should I change a MERV 13 filter if I have pets?
Expect to change MERV 13 filters every 30–90 days depending on shedding and system run time. Single-pet, low-shed homes may get 60–90 days, while heavy shedding or multiple pets often need changes every 30–45 days to avoid clogging and reduced airflow.
Will a MERV 13 filter damage my HVAC system?
Most modern residential furnaces and AC units handle MERV 13 without issue, but check your owner's manual. If your system is old or has a weak blower, monitor for reduced airflow and consult an HVAC tech before using higher-MERV filters long-term.
Do activated-carbon filters remove pet dander?
No — activated carbon reduces odors and some VOCs but doesn't improve particle capture. For dander control, choose MERV 11–13 pleated or electrostatic media; carbon is a complementary feature if smells are also a concern.
