MERV 14 is typically considered too high for residential use unless there are specific health concerns or air quality issues requiring such high filtration efficiency.
MERV 8 to 11 is generally best for home use, offering a good compromise between filtering capability and maintaining efficient airflow.
For most homes, MERV 11 is better, providing ample filtration for common household particles while maintaining system efficiency.
HVAC air filters should be changed every 1-3 months, depending on filter type, usage, and air quality, to maintain efficiency and indoor air quality.
Expensive air filters may last longer due to higher quality materials and construction, but longevity also depends on usage conditions and maintenance.
