### Claim 2 (depends on 1)

The portable hydration system of claim 1 wherein said bag comprises at least one shoulder strap.

### Claim 3 (depends on 1)

The portable hydration system of claim 1 wherein said pump comprises:
a housing;
a piston;
at least one filter; and
a pressure recovery mechanism.

### Claim 4 (depends on 3)

The portable hydration system of claim 3 wherein said pump housing comprises at least one substantially cylindrical cavity for housing said piston and said filter.

### Claim 5 (depends on 3)

The portable hydration system of claim 3 wherein said filter comprises a reverse osmosis filter.

### Claim 6 (depends on 3)

The portable hydration system of claim 3 wherein said filter comprises a printed membrane.

### Claim 7 (depends on 3)

The portable hydration system of claim 3 wherein said oxidant generating electrolytic cell is housed within said pump housing.

### Claim 8 (depends on 3)

The portable hydration system of claim 3 wherein said oxidant generating electrolytic cell is positioned on said pump housing.

### Claim 9 (depends on 3)
