Cell Tower, Wifi Radiation Protective Natural Box Canopy US King (84" x 88" x 78")

I tested this canopy with an Acousticom 2 meter, HFE35C and HFW35C HF Analyzers and it is a real emf shield. This canopy blocks out a significant amount of EMF radiation. The fabrics feels like a sheer cotton mesh, very light weight and breathable but surprisingly very good at blocking EMF radiation. I already washed it once in the hand wash cycle in my machine and hung it dry from the ceiling hooks it comes with and it still works the same blocking out most EMF. I liked it so much I bought another one for my daughter. Excellent product and necessary for a good nights sleep for those who are sensitive to EMF radiation.
