I have a Samsung refrigerator which uses the Magic Water Filter.
Looking around on the Internet www.uk-fridge-filters.co.uk seem to do
a compatible one at about £15 which seems way too cheap compared to
the original manufacturers part (currys said around £50).

Does anyone know anything about these filters, or if the Samsung one
contains anything special? I do not want to invalidate the warranty
of the product or risk breaking the fridge itself.
