Frequently Asked Questions
How often should I change a pleated filter in a dusty summer?
Inspect the filter monthly during dusty periods; expect to change it every 60–90 days depending on dust load, number of occupants, and pet presence. In very dusty conditions consider swapping every 30–45 days.
Is MERV 8 enough for dusty summer regions?
MERV 8 is a practical balance for residential systems: it captures most common dust and pollen while minimizing airflow restriction. For severe allergy or health needs, consider consulting an HVAC pro before moving to a higher MERV rating.
What if a replacement filter feels smaller than my slot?
Check the product's actual dimensions (many list nominal vs actual sizes). If a filter is undersized, it can allow bypass and reduce effectiveness. Return or exchange for the exact fit, or add a gasket/foam seal as a temporary fix while ensuring no airflow restriction.
