Customer Experience:

"OMG! The pollen has started in earnest and guess what?! These screens are keeping the house pollen free! I cannot believe it. I am going to do the master bedroom screens tomorrow as it is a dust bowl. Yech! 
I will take some pictures to show the difference. It is amazing. I am so pleased. Well, I am going to post on local forums and FB pages about this. . Can I put your name and 800# out there?"
