Frequently Asked Questions
Are MERV 13 filters always better for allergies?
Not always. MERV 13 captures smaller particles than MERV 8, which can help severe allergy sufferers, but it also increases airflow resistance. If your HVAC system isn’t rated for the pressure drop, performance and energy efficiency can suffer. For many homes, a high-quality MERV 8 pleated filter provides meaningful allergy relief without airflow issues.
Will a thicker filter (2" or 4") improve performance?
Thicker filters generally have more media and dust-holding capacity, so they last longer and can capture more over time. A 4" filter typically needs replacement less often than a 1" filter, but you must have a compatible housing. Thicker filters can also be sturdier, which reduces leakage and bypass.
How often should I replace these pleated filters?
Replacement depends on household conditions—pets, smoking, and high dust increase load—but a common schedule is every 60–90 days for 1–2" pleated filters. A 4" filter can often last longer between changes. Check your filter monthly and replace when visibly dirty or according to the manufacturer’s guidance.
