Frequently Asked Questions
Will switching to MERV 13 help my fall allergies?
MERV 13 captures smaller particles than MERV 8 or 11 and can noticeably reduce indoor pollen and fine dust, which helps many allergy sufferers. Before switching, confirm your HVAC blower and filter slot can handle the higher resistance to avoid reduced airflow or system strain.
How often should I change a pleated filter during allergy season?
Check filters monthly during peak pollen months and expect to replace typical 1" pleated filters every 60–90 days. If you use high-MERV filters or have pets and heavy dust, changing every 30–60 days may be necessary.
What's the difference between 1" and 2" filters?
2" filters contain more filter media, hold more dust, and often last longer between changes. They can offer equal or better filtration with similar airflow impact if installed in a system designed for 2" depth. Make sure your return grille or furnace accepts 2" filters before buying.
