Filtration and Air Quality
MERV 8 is a widely recommended filtration level for most homes. It is effective at trapping common household particles such as dust, lint, pollen, pet dander, and mold spores without significantly restricting airflow through your heating and cooling system. The pleated construction shown in the product images provides a larger filtration surface than basic fiberglass filters, helping to protect your HVAC equipment and improve indoor air quality.
