Silver Fiber EMF Protection Bandana Mask

A stretchy, multi-way bandana in silver fiber fabric that you can wear as a face mask, a bandana or a hat. The conductive fabric reduces radio-frequency (RF) signals passing through whatever part of the head or face it covers. It's for people who want one flexible piece of shielding headwear rather than several.

Details

• Material: 75% spandex, 25% silver fiber
• Stretch: 4-way
• Size: one size; about 24 x 50 cm (9.4 x 19.7 in) laid flat
• Color: silver grey
• 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 bandana, doubled over, 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. Knit fabric opens up slightly when stretched, so you can also compare readings relaxed and pulled tight.

Honest Notes

• It's not a respiratory or dust mask, and we make no filtration claims.
• It only reduces RF where it's worn; everything else is unaffected.
• It's not a medical device.
