A. Specification Material: 100% cotton fabric + silver fiber Colour: primary color 60 inch x 80 inch / 153cm x 203cm for Double Bed Size B. HOW TO USE THE EARTHING Fitted sheets. 1. Step 1: Check Your Outlets For Ground Connect it to the ground port of a grounded 3 - prong outlet. Before plugging in your Earthing product, check if the outlet is grounded by plugging in the outlet checker. 2. Step 2: Setting Up The Fitted Sheet - Place the Earthing sheet over your mattress. - Insert one end of the Earthing cord into the ground port (third hole) of a properly grounded wall outlet or connect to cord of an Earthing ground rod placed in the Earth outside. - When you lie down on the connected sheet, any bare skin contact will transfer the Earth's energy to your body once you connect the sheet. 3.

Our kit incorporates a 98k ohm resistor that acts as a safety fused link but more importantly it creates a more organized exchange of Earth's electrons and better grounding effect. There is a relatively powerful feel with a 98k ohm resisted link. Extensive research has shown that a 98k ohm resistor matches the same ground potential of the human body for relatively good results.
