These air filters are probably the best I've ever purchased, and for less that the ones you find at the grocery store or home supply store.

Custom Filter Required

Measure twice, cut once also applies when measuring for your filter requirements. I first ordered a standard size and the furnace collapsed the filter. I re-measured and had this custom size filter made and now everything is working correctly!

Merv 11 filters.

I recommend the merv 11 filters, before we used merv 8 and I would wake up in the morning with a throat full of phlegm and a scratchy voice. Really seems like the merv 11 traps more particals. I would buy them again.

Overall, seems like a great deal. My only issue is that it's a tight fit.
