Frequently Asked Questions
How often should I change a 1-inch pleated filter?
Filtrete recommends changing these 3-month pleated filters every 90 days under typical conditions. Homes with pets, smokers, or heavy dust may need replacements every 30–60 days.
Will MERV 5 / MPR 300 filters restrict airflow?
MERV 5 / MPR 300 filters are designed for everyday residential use and typically balance particle capture with airflow. If your system is older or very sensitive, check manufacturer guidance — higher-MERV filters can increase resistance and affect performance.
What if the filter doesn't fit my slot?
Measure the actual filter slot and compare with the manufacturer's actual dimensions printed on the pack. If a filter is slightly oversized or undersized, it can cause leaks or gaps; return or exchange the multi-pack rather than forcing a poor fit.
