Dunno whether it would work, also I know nothing about wine and cider brewing but if like beer brewing you don't want to introduce oxygen into the finished brew using a brita jug would do just that
Was brand new and I sterilized it like any other piece of kit. Removed all sponges and filters and put in a bag of active carbon. 2 days later it was crystal clear and took out all nasty tastes. Quite an easy drink even neat now. :)
