Frequently Asked Questions
How often should I replace my furnace filter for summer allergies?
For 1-inch pleated filters, replace every 60–90 days under normal conditions; if anyone in the home has allergies or you have pets, check the filter monthly and replace sooner if it looks dirty. Thicker 2-inch filters can last longer but still need inspection every 60–90 days.
Which MERV rating is best for seasonal allergies?
MERV 8 is a solid baseline for seasonal pollen and dust with minimal effect on airflow. Choose MERV 11 if you need finer particle capture (pet dander, smaller allergens), but confirm your HVAC system can handle the increased resistance before upgrading.
What if my filter seems smaller than the listed size?
Measure the filter slot in your furnace and compare to the product's actual size listed in the specs. Some users report slight size variance—if a filter is too small, it can allow bypass leakage. When in doubt, choose the exact actual dimensions supplied and consider a sturdier framed or thicker option for a tighter fit.
