What MERV rating are you using for your filters?
Air filters are rated according to how much dirt (microns) they can catch across 3 size levels.
The higher the rating, the better the filter performs its job. We've created a MERV chart to easily identify how filters perform at different MERV ratings.
See below our MERV rating chart for quick access to how filters perform, which application it's for, and what types of filters are typically used.
