With the horrible air quality from #ABWildfire I’ve put some MERV13 rated furnace filters in my windows so we can get clean, cool air in the house. It filters pollution out of the air as it blows into the house. Filtrete1900’s are MERV13. #yeg #yyc 
To fill the large gap on top I cut a piece of cardboard and duct taped it to the filter. Used some peel & stick weather stripping along the edges of the filter & cardboard. So it’s easy to take in and out.
I’ve also got #corsirosenthalbox and HEPA filters running inside the house. I’ve made a variety of types over the years using different fans & filters. Lots of size and noise options.
