The polypropylene lining is used all over Europe and is approved by the European government as an effective protection layer for indoor wear. This filters out particles in the air as well as providing protection from droplets. Polypropylene is great as a physical filter but has another benefit: It holds an electrostatic charge. In other words, it uses the power of static electricity. Think of the static cling that can happen when you rub two pieces of fabric together. The "cling" traps incoming — and outgoing — droplets. "That's what you want — the cling is what's important. The US Government is NOW recommending 3 layers for safety!
And unlike other materials, polypropylene keeps its electrostatic charge in the humidity created when you breathe out, says Yi Cui, a professor of materials science and engineering at Stanford University who co-authored the Nano Letters study with Chu.
Polypropylene will lose its electrostatic charge when you wash it, but you can recharge it by ironing it or by rubbing it with a plastic glove for around 20 seconds. Once you've got static cling, ka-ching — you're back in business. With these masks, you get the comfort and benefit of organic GOTS certified muslin against your skin, but the breathable protection of polypropylene in the middle filtering particles.

Masks will shrink, especially if washed in hot water and dried in dryer. Lay flat to dry or tumble dry on low. To renew charge and effectiveness after washing, a warm iron is recommended or rub with plastic gloves.
