The Y-Fry radiation protection router bag will dramatically reduce your family’s EMF radiation exposure. Designed here in the UK using Swiss Shield fabrics and our own BlocSilver, it is fully tested. Naturell will shorten your Wi-Fi range but dramatically decrease your EMF exposure (up to 2.4 GHz). New Daylite offers a smaller reduction in microwaves (up to 2.4 GHz) but leaves your broadband signal almost uninterrupted. If you have a modern 5 GHz router, opt for the BlocSilver fabric.
