Frequently Asked Questions

What does MERV rating mean for Filterbuy filters?

MERV, or Minimum Efficiency Reporting Value, measures a filter's ability to capture particles. Filterbuy's MERV 8 handles common dust and pollen, while MERV 11 captures finer allergens like pet dander for improved indoor air.

Are Filterbuy filters made to exact sizes?

Yes, Filterbuy provides actual dimensions slightly undersized for easy installation, such as 19.50 x 19.50 x 0.75 for a nominal 20x20x1 filter, ensuring a secure fit without custom cutting.

Can Filterbuy products be used in all HVAC systems?

Most standard residential furnaces and AC units accept Filterbuy pleated filters. Check your system's specifications for MERV compatibility to avoid airflow issues.

Do Filterbuy filters include activated carbon?

Select products like air cleaner replacement pads feature activated carbon for odor control, while standard furnace filters rely on electrostatic pleating for particle capture.

How often should I replace Filterbuy furnace filters?
