Frequently Asked Questions
How often should I change pleated filters during the summer-to-fall transition?
Check filters monthly during high-dust summer and peak pollen in early fall. Many manufacturers recommend changing standard 1" pleated filters every 30 days in heavy-use periods; otherwise 60–90 days is typical. If the filter looks dark and clogged or airflow drops, change it sooner.
Is MERV 8 sufficient for pollen and summer dust?
Yes. MERV 8 pleated filters effectively capture dust, lint, mold spores and most pollen while maintaining low airflow resistance. For homes with severe allergies or smoke concerns, a higher MERV rating may capture finer particles but can restrict airflow—check compatibility with your HVAC system before upgrading.
Will using a thicker 2" filter harm my HVAC system?
A 2" pleated filter itself won’t harm your system if the cabinet or filter rack accepts it and the filter has low resistance. Thicker filters can reduce how often you change them because they hold more dust. Always ensure the filter fits snugly with no gaps and check your system manual or HVAC technician if unsure.
