Well, still have to add a Honeywell Hepa filter to the living space. My city cut down 100's of trees to put in acres of asphalt and I live close to an Interstate and a lot of new home construction...
Need to supply a rim trim of heavy material larger than the filter. Most A/C grills filter trims are little larger than yours filter. Had to use tape to hold filter in place, air return sucks filter up into duck.
How do I know this is MERV 13?Any performance information, for example pressure drop across the filter for example?Newly installed so I will track performance
