Reverse Osmosis Water Filters (Worle BS22)

Hi
I have six brand new filters suitable for water filters, reverse osmosis units or possibly even fish tanks.
I have just scrapped my RO unit and these are new left over filters.
There are: 3 x Activated Carbon GAC (2 Aqua House brand, 1 some other brand), 2 x Carbon Block filters, Aqua House brand, and 1 x unbranded particulate filter, but I do not remember if it is 1 or 5 microns.
I am happy to leave them well wrapped, outside, for an easy collection.
