Denis,

I'm not sure I really understand what you're asking, but when I decided to
upgrade the MERV ratings of my furnace filters I called the company that
sold and installed it and they told me the maximum MERV number that would
work in that furnace is 11. So I bought a dozen 20x14x1 MERV 11 filters.

When I looked into this issue I read some web sites that explained that
furnace fan capacity and other factors set an upper limit to the MERV value
that will work without shortening furnace life.

HTH,
