Question:
I wrapped my cell phone up in the hat. and watched for an hour. i was able to receive calls, texts and fb messages while wrapped in the hat.
Answer:
Please be sure that the Cap you received is from EMR Shielding Solutions, you will find this information written on the label inside the Cap; written EMR Shielding Solutions, and Made in Canada. The Cap significantly reduces the RF signal. A cell phone needs very low signal in order to operate. The best approach is to measure the shielding levels with a meter.
For example, place the measurement meter inside the Cap and while pointing the Cap to RF source such as a Wifi modem. You will notice the level drops significantly, about more than 10 times lower.
Question:
Is the hat washable and would washing it alter it's effectiveness?
Answer:
The EMF and RF Protection CAP can be Hand-washed. The EMF shielding material used for the shielding the cap does not contain silver, therefore the effectiveness of the cap will remain the same after the washing.
