CPAP machine filters (Cliffe BN7)

Seven filters to fit a Fisher & Paykel Icon CPAP machine. I sourced them from the USA via eBay, because they were so expensive in this country; but now I have been moved onto a different machine which uses different filters, so these are available for anyone who uses an Icon machine. Each one is in an unopened individually-sealed plastic packet (apart from one which has two in it!).
