Frequently Asked Questions
Do I need MERV 13 for wildfire smoke?
MERV 13 filters capture more fine particles (including PM2.5) than MERV 11 and are recommended for wildfire smoke when your HVAC system can handle the slight increase in airflow resistance. If unsure, consult your system manual or an HVAC technician.
Can I use a pleated filter with a carbon layer for odors?
Yes. Combining a pleated electrostatic filter for particulates with an activated carbon stage or a carbon-coated pleat helps reduce gases and odors. Many homeowners use a high-MERV pleated filter plus a separate carbon filter or a portable carbon/HEPA purifier.
How often should I change 1-inch pleated filters during and after smoke events?
Under heavy smoke replace 1-inch pleated filters every 30–60 days or sooner if they look dark or airflow drops. During normal conditions follow the manufacturer guidance (around every 90 days) but check more frequently after prolonged smoke exposure.
