HCS provides the Hamshari Dialysis Center with the monthly consumable sets of filters, solutions, and other necessary supplies so that Palestinian Refugees can use the service for free. Refugees are not able to afford to pay for dialysis sessions, (one needs 2 or 3 sessions per week) which costs 100$/session (this is the cheapest). They suffer from bad environmental conditions which make them more susceptible to diseases. In addition, the majority of them are unemployed.
