Frequently Asked Questions
Do activated-carbon furnace filters remove cooking VOCs?
Activated carbon can adsorb many common kitchen VOCs and odorous molecules, reducing smells throughout a home when used in a central HVAC system. However, carbon capacity is finite—heavy cooking will exhaust the carbon sooner, so replace filters more often during busy periods.
Will a MERV 8 carbon filter restrict my HVAC airflow?
MERV 8 is typically safe for residential furnaces and air handlers, but improper sizing or very tight systems can experience increased resistance. Choose the largest compatible filter face area, confirm the filter’s actual dimensions, and follow your HVAC manufacturer’s recommendations.
How often should I change filters during the holidays?
For heavy holiday cooking, consider changing to a fresh carbon pleated filter just before the event and again after, or at least check filters every 30–60 days. Frequent changeouts keep carbon working at peak capacity and maintain airflow.
