A portable water disinfecting and purification apparatus comprising a first chamber into which water to be purified may be drawn by suction or negative pressure, a second chamber into which the water from the first chamber can be forced by a pumping action or positive pressure, whereby the water is initially passed across a pre-filter secured over the inlet to the first chamber and having a very small pore size and an inner cavity in which a disinfecting agent is place to filters most contaminants before the water is drawn into said filtering device, and once in the first holding chamber the water is isolated and may be further treated with a disinfectant agent, and then is passed though at least additional filtering substance including an activated carbon or nano-filter.

1. A portable water purification apparatus comprising: (a) a first chamber into which water to be purified may be drawn through an entrance by negative pressure and isolated for immersion in a disinfecting agent,(b) a second chamber slidable within the first chamber, said second chamber having an outlet and an inlet through which water in the first chamber is transferred by a positive pressure,(c) a pre-filter connectable to said apparatus such that water to be purified is passed through said pre-filter prior to entering the first chamber through said entrance, said pre-filter alternatively connectable over the outlet of the second chamber so as to enable clean water to be passed through the pre-filter in a reverse direction to aid in removing debris and contaminants from said pre-filter so that the pre-filter can be reused,(d) at least one micro-filter provided in said second chamber through which water is passed prior to exiting the second chamber through said outlet, and(e) a container securable over the pre-filter when the purification apparatus is not in use, said container also being usable to receive and collect potable water passed through said apparatus. 2. A portable water purification apparatus in accordance with claim 1 in which the pre-filter is comprised of a porous polyethylene material having a pore size of about thirty-five microns or less. 3. A portable water purification apparatus in accordance with claim 1 additionally comprising a mouthpiece securable over the outlet to the second chamber for directing water forced through the micro-filter into the mouth of the operator of the apparatus or into a storage container. 4. A portable water purification apparatus in accordance with claim 1 wherein the second chamber is slideable within the first chamber to provide both an initial negative pressure at the entrance to the first chamber for drawing water into the first chamber as the second chamber is withdrawn partially from the first chamber and to provide positive pressure in the second chamber as such first chamber is returned into said second chamber. 5. A portable water purification apparatus in accordance with claim 4 in which appropriate check valves are provided at the entrance to the first chamber and inlet to the second chamber to allow passage of water in only one direction from the pre-filter into the first chamber and the first chamber into the second chamber, but not in the reverse direction. 6. A portable water purification apparatus in accordance with claim 5 in which the first and second chambers are in the form of close fitting tubular elements with the second chamber in sliding engagement with the first chamber and additionally comprising a flexible gasket on the outer surface of the inlet end of the second chamber to provide an airtight seal between the first and second chambers. 7. A portable water purification apparatus in accordance with claim 6 wherein the walls of the tubular elements are transparent or translucent to allow the operator to monitor the internal operation. 8. A portable water purification apparatus in accordance with claim 1 in which the pre-filter additionally comprises an internal cavity for housing a disinfecting agent in which water passed through the pre-filter is immersed prior to entering the first chamber. 9. A portable water purification apparatus in accordance with claim 1 additionally comprising a disinfecting agent provided within a section of the second chamber. 10. A portable water purification apparatus in accordance with claim 1 additionally comprising a separable containment area in the second chamber in which micronutrients or other desirable additives may be combined with the resulting potable water. 11. A portable water purification apparatus in accordance with claim 1 additionally comprising a counter arrangement for tracking the number of uses of said apparatus and as an aid to determining when at least one disinfectant agent, purifying substance, or filter used with the apparatus should be replaced with a new supply of said agent, substance, or filter. 12. A portable water purification apparatus in accordance with claim 1 additionally comprising a storage compartment in said container. 13. A portable water purification apparatus in accordance with claim 12 in which the at least one micro-filter in the second chamber includes an activated carbon filter and a nanofilter. 14. A portable water purification apparatus in accordance with claim 1 in which one or more additional chambers through which water to be made potable by said apparatus is passed are connectable to either the first or second chambers for holding either another filter or a purifying agent. 15. A portable water purification apparatus in accordance with claim 8 in which disinfecting agent to be placed in said pre-filter internal cavity is chlorine at concentrations of between 25-55 ppm for the appropriate disinfecting time period. 16. A portable water purification apparatus comprising: (a) an elongated outer chamber, said chamber having an entrance through which water enters said outer chamber by negative pressure, and an exit,(b) an elongated inner chamber telescopingly slidable within the outer chamber in an airtight manner, said inner chamber having an inlet into which water in the first chamber is transferred by a positive pressure upon exiting said outer chamber through said exit, and an outlet,(c) appropriate one-way check valves provided at the entrance to the outer chamber and inlet to the inner chamber to allow passage of water in only one direction into the outer chamber, and from the outer chamber exit into the inner chamber inlet, but not in the reverse direction, and allowing water to be isolated in said outer and inner chambers,(d) a pre-filter connectable to said apparatus through which water to be purified is passed prior to entering the outer chamber through said entrance, said pre-filter alternatively connectable over the outlet of the inner chamber so that clean water passed through said apparatus and said pre-filter will flush debris and contaminants from said pre-filter,(e) at least one nano-filtering device in said inner chamber through which water is passed prior to exiting through said outlet, and(f) a combination protective covering and container securable over the entrance to the outer chamber and alternatively usable to collect water passed through said apparatus. 17. A portable water purification apparatus in accordance with claim 16 additionally comprising a sleeve attachable to said outer chamber having a central passageway forming the entrance to said outer chamber and supporting the one-way check valve at the entrance to the outer chamber, and a collar section to which the pre-filter is securable. 18. A portable water purification apparatus in accordance with claim 17 additionally comprising a collar member secured to said outer chamber having a central orifice in which the inner chamber is slidingly received, and an end plug securable to said inner chamber which supports the one-way check valve over the inlet to the inner chamber. 19. A portable water purification apparatus in accordance with claim 18 additionally comprising a mouthpiece securable over the outlet end of the inner chamber, said mouthpiece having an internal orifice in communication with the outlet of the inner chamber, said mouthpiece adapted to be received in said combination protective covering and container when used to collect water passed through said apparatus. 20. A portable water purification apparatus in accordance with claim 19 in which the pre-filter additionally comprises an internal cavity for housing a disinfecting agent to be mixed with water prior to entering the outer chamber.
