Pair x PWW10 - C-4310 Replacement Filter
This filter will need changing very regularly, its 4" square size means it doesn't hold much, and because filters are the key to good sanitation it will need cleaning every week. But don't worry this is what it's designed to do.
Please see the guides regarding filter cleaning.
Why not buy 2 or more to make sure you always have a spare clean filter?
