## Abstract

Some embodiments of the present disclosure include a portable liquid filtration system for providing a user with filtered liquid from a non-filtered source. The system may include a drinking conduit extending from a housing, the housing having a liquid entrance port at an end of the housing distal from the drinking conduit, and at least one organic filter and at least one chemical filter positioned within the housing. The filters may include charcoal containers, iodine-treated sieves, carbon filters, an untreated sieve, and a hexafluoro alcohol treated sieve. When non-filtered liquid is drawn into the liquid entrance port, through the housing, and to the drinking conduit, the liquid may pass through all of the filters, resulting in the liquid being filtered when it reaches the drinking conduit. The system may also include at least one solar panel attached to a UV light positioned within the liquid entrance port.

## Claims

### Claim 1

A method of filtering water comprising the steps of:
providing a portable water filtration system for filtering a non-filtered water source, the portable water filtration system including:
a drinking conduit extending from one end of an elongated, substantially cylindrical, hollow housing including at least one solar panel, and a liquid inlet port at a distal end of said housing;
at least one carbon filter positioned within said housing;
at least one iodine treated sieve positioned within said housing;
at least one hexafluoro alcohol treated sieve positioned within said housing;
an ultraviolet light positioned proximate to said liquid inlet port and operatively connected to said at least one solar panel; and
a button operatively connected to said ultraviolet light, and positioned proximate to said drinking conduit, said button being operable to illuminate said ultraviolet light when pressed;
immersing said distal end inlet into a body of water; and
drawing water through said inlet of said portable water filtration system by placing the user's mouth about said drinking conduit and sucking, wherein non-filtered water is drawn into the liquid inlet port, through said housing, and to said drinking conduit, the non-filtered water passing through said filter/sieves, resulting in filtered water when it reaches the drinking conduit.

### Claim 2 (depends on 1)

A method of filtering water as set forth in claim 1 further comprising the step of:
pressing said button, thereby illuminating said ultraviolet light.
