Take thisnfor what you will. For those unaware: Merv 8 is the max filtration that the majority of units recommend!
Using higher than this can result in your systems overworking themselves to breathe, unless your system is specifically designed for higher than Merv 8 (which again, isn't common)

For those that dont know, merv rating is filtration level. Hvac unita dont care about that. They care about pressure drop, which is basically the resistance the filter causes to make it work harder. Filter design can greatly impect pressure drop significantly.
