Frequently Asked Questions
How often should I change a carbon-infused pleated filter if I cook a lot?
For frequent indoor cooking or heavy BBQ smoke exposure change every 1–3 months. In lighter-use homes 3–6 months is typical. Heavier smoke and greasy kitchens require more frequent swaps to keep the carbon active and preserve airflow.
Will a carbon filter remove BBQ smoke completely?
Carbon filters reduce many odor-causing gases and some VOCs and will noticeably cut lingering smoke smells, but they won’t eliminate all odors instantly. Combine a carbon filter with ventilation (range hood or opening windows) for the best results.
Can a high-MERV filter damage my HVAC system?
High-MERV filters (MERV 13–15) can increase airflow resistance. Check your system’s specifications — older or weaker blowers may struggle with higher-resistance filters. If in doubt, choose a mid-range MERV 13 or consult an HVAC tech before upgrading to MERV 15.
