Frequently Asked Questions
Will a MERV 13 filter restrict my HVAC airflow?
Possibly. MERV 13 filters have denser media than basic fiberglass filters. Most modern HVAC systems handle MERV 13 fine, but older or undersized blower systems may experience reduced airflow. Check your system manual or consult an HVAC tech before upgrading.
How often should I change carbon-augmented filters during smoky seasons?
Change intervals depend on smoke load and use, but expect to change carbon-augmented pleated filters every 1–3 months during heavy smoke events. Inspect filters visually — if they look darkened or airflow seems reduced, replace sooner.
Do carbon filters eliminate all smoke smell?
Carbon layers significantly reduce many smoke-related VOCs and odors but won’t remove every trace instantly. Combining a carbon-augmented furnace filter with source control (closing windows, running HVAC on recirculate) and portable air cleaners with activated carbon will give the best results.
