It's good but no. Snow has thousand of bacteria plus it traps many pollution, pestidees and industry chemical and also many people walk and even animals do. But if you can do, boil the water, filter it through cloth and then warm it up again and don't add other snow on it, just mid warm and use it as the down is much sensitive part and it can cause irritation
