Frequently Asked Questions
Do carbon-pleated filters remove VOCs and smoke?
Yes—activated carbon adsorbs many odorous gases and common VOCs, and pleated media traps smoke particulates. Effectiveness depends on carbon amount and contact time; deeper carbon beds and thicker media capture more and last longer.
Will a higher MERV carbon filter reduce my HVAC airflow?
Higher MERV filters can increase resistance. MERV 13–15 filters are effective but may reduce airflow on older or low-power systems. Use filters your HVAC is rated for or consult an HVAC technician before upgrading.
How often should I replace carbon-pleated filters?
Replace 1" pleated filters every 30–90 days depending on use and air quality. Deeper 4" filters can last 3–6 months or longer. Replace sooner after heavy smoke exposure or if you notice odors returning or higher dust loads.
