How long can I reuse my Coffee Sock for?

If you take good care of your Coffee Sock it could last years!   The
estimated life span of a frequently used Coffee Sock is 6-12 months.  
If the Coffee Sock is not allowed to dry it may become mouldy and this is the
end for that Coffee Sock (however this can be avoided! – Refer to ‘How do I
clean my Coffee Sock?)
