I've been using the R-pur mask for a few weeks now and it has been a game-changer. The mask fits perfectly and is comfortable to wear for long periods of time. The filtration system is top-notch and I can feel the difference in the air I breathe. I highly recommend R-pur to anyone looking for a high-quality mask. It's worth every penny!
