Frequently Asked Questions
How often should I change filters during wildfire smoke or heavy pollen?
Increase replacement frequency during heavy smoke or peak pollen. While normal guidance is 60–90 days, many homeowners change filters every 30 days during intense smoke or allergy seasons to keep airflow steady and capture efficiency high.
Can I use MERV 13 filters in any HVAC system?
Not always. MERV 13 offers higher particle capture but can increase resistance. Check your HVAC manual or consult an HVAC technician to confirm your system's fan and filter slot can handle a MERV 13 1" pleated filter without reducing airflow or stressing the blower.
My filter seems a bit small or loose—what should I do?
Measure the actual slot and compare to the filter's actual dimensions. Some customers report slight size variance across brands. If a filter is too small or shifts, it can allow leaks; try a different brand/size or use a properly sized filter frame or adapter to ensure a tight seal.
