★[GREENER LIVING ENVIRONMENT] The harmful from wifi router may not be very high, but it is still microwave radiation. There are many studies that link the radiation to a host of other sicknesses and neurological problems. We think we are keeping our children safe and we do not realize how much danger we are putting them in by exposing them to all of these electromagnetic toxins. While this wifi router cover could protect us..
★[GOOD PERFORMANCE] Our EMf blocking WIFI Cover is made of breathable emf protection fabric that allows a natural air flow for cooling. Just tuck around the entire modem/router for the greatest performance. while it may affect wifi signal if wrapping the entire router, we suggest only wrapping the router antennas when you use wifi. And wrap the entire router when you are sleeping or outside. Please note, the cover is not advised to wash..
★[PROTECTING FROM NOW] How close the harmful source is to our physical bodies, how much radiation we are in. Also the longer the exposure time is, the more harmful it can be. When we re....
