I tested this fabric in hopes that it would block EMF from some electronic equipment in my office. I put this fabric between my subwoofer and my GQ Electronics EMF Meter and it did absolutely nothing to block the high EMF coming from that speaker...ZERO help. I also tested it with my cell phone and it did nothing, once again. I am highly sensitive to EMF, RF etc and when I held this fabric near my body, I actually could feel an extremely negative affect on my body, including my heart itself... like actual pain. It was very strange when I noticed it the first time handling this fabric, but double checked it again a couple of days later before telling Amazon that I was returning it and it happened again.
