Frequently Asked Questions
Is MERV 13 safe to use in my home HVAC system?
Most modern residential systems handle MERV 13 without issue, and it provides superior allergen and smoke particle capture compared with MERV 8 or 11. Confirm your HVAC manufacturer’s recommendations — older or low-powered blowers sometimes perform better with lower-MERV filters to avoid strained airflow.
How often should I replace a MERV 13 filter in summer?
Replace intervals vary by indoor pollution and filter size, but a common recommendation is every 60–90 days. If you live in a wildfire-prone area or have heavy pollen exposure, check the filter monthly and replace sooner if visibly loaded.
Why do some customers say the filter 'size' is off?
Some buyers report actual dimensions slightly smaller than the nominal size printed on standard product labels. Measure your filter slot and check the product’s listed 'actual size' (e.g., 9.75 x 24.75) to ensure proper fit and avoid returns.
