Yes @lostforgottensoul exactly, there's a wire in there. Wash your hands, stretch it out, tuck over ears, tuck under chin, pinch at nose, squeeze with both hands flat on your cheeks (cup your face- i.e. you can touch with wild abandon lol), then wash again. When you remove, lean forward, take off by straps and don't touch it but fold it sort of inwards and throw out and wash again. If you do need to adjust (sometimes it rides up over lower eye lashes, or worse gets stuck under, use the straps. You can pinch the wire more, but I'm allergic to metal so I can't, but safety visor holds it a bit too. It will last in heat 2-3 hours, or longer if you must, but if it gets wet change it because filter plugs and you'll breathe through the sides and that is not going to help a thing. :hug:
