Silver Fiber EMF Shielding Face Mask

A one-size face mask made from 100% silver fiber. The conductive fabric reduces radio-frequency (RF) signals passing through the part of the face it covers, the nose, mouth and lower face. It's for people who want face coverage to go with a silver fiber hood or cap.

Details

• Material: 100% silver fiber
• Colors: gray, red stripe or blue stripe, plus a gray children's version
• Size: one size; the children's version is gray only
• Care: hand wash in cold water and air dry. Skip bleach, fabric softener and hot washes, which wear down silver fiber's conductivity

How to Check It Works

Take a reading with an RF meter, or note your phone's signal bars, then wrap the meter or phone in the mask, folded double, with no open edges and check again. A lower reading or fewer bars shows the fabric attenuating the signal. The amount depends on the source, the distance and how many layers you wrap, so we don't promise a number.

Honest Notes

• It's not a respiratory, surgical or dust mask, and we make no filtration claims.
• It covers the lower face only. Eyes, forehead and the rest of the head are unaffected; a hood covers more.
• It's not a medical device.
