a bottom element detachably connectable to the top element and having an inner surface at least partially defining the reservoir, the bottom element comprising an end wall, a bottom wall extending around a bottom axis, and a bottom opening extending between the end wall and an opposing end of the bottom wall, the bottom element being formed from a resilient material that is of a second hardness less than the first hardness to facilitate squeezing of the bottom element to transition at least a portion of the bottom wall toward the bottom axis, the top element and the bottom element collectively defining a seam at a junction therebetween;

a collar extendable around the seam to strengthen connection between the top element and the bottom element;

a cap connectable to the top element and having a cap passageway communicable with the reservoir; and

a filter assembly positionable in the reservoir, the filter assembly comprising:

a lower body positionable in spaced relation to the end wall of the bottom element and defining a lower body cavity;

a lower filter positioned within the lower body cavity; and

a filter passageway disposable in fluid communication with the lower body cavity and the cap passageway;

the top element, the bottom element, the cap, and the filter assembly being configured such that transition of the bottom wall toward the bottom axis urges fluid in the reservoir to flow through the lower filter, then through the filter passageway, and then through the cap passageway.

2. The bottle recited in claim 1 , wherein the cap additionally includes an inlet opening separate from the cap passageway and an inlet valve in communication with inlet opening to control fluid flow through the inlet opening.

3. The bottle recited in claim 2 , wherein the inlet valve is transitional between a closed position and an open position, the inlet valve restricting fluid flow through the inlet opening when the inlet valve is in the closed position.

4. The bottle recited in claim 3 , wherein the inlet valve is configured to assume its closed position in response to the bottom wall being squeezed, and to assume its open position in response to the bottom wall being subsequently released.

5. The bottle recited in claim 1 , further comprising a support coupled to, and extending from, the end wall of the bottom element and configured to support the lower body in spaced relation to the end wall.

6. The bottle recited in claim 1 , further comprising a pH modifier positionable in communication with the cap passageway, the pH modifier being configured to alter a pH of a fluid flowing therethrough toward a prescribed pH value.

7. The bottle recited in claim 1 , wherein the filter passageway is at least partially defined by a tube and an upper body, the tube being connectable to the lower body and the upper body, and the upper body being connectable to the cap.

8. The bottle recited in claim 1 , wherein the bottom element is formed of a material that has a Shore A hardness.

9. The bottle recited in claim 8 , wherein the bottom element is formed of a material that has a durometer of 20 or higher.

10. The bottle recited in claim 9 , wherein the top element is formed of a material that has a durometer of 70 or higher.

11. The bottle recited in claim 1 , wherein the bottom element is formed from a Thermo Plastic Elastomer material.

12. A hand squeezable drink bottle comprising:

a body defining a bottle reservoir for retaining a fluid, the body defining a bottle axis, the body having an upper segment and a bottom segment adjacent the upper segment and detachably connectable to the upper segment, the upper segment and the bottom segment collectively define a seam at a junction therebetween, the bottom segment being transitional relative to the upper segment between a first position and a second position, a portion of the bottom segment being moved toward the bottle axis as the bottom segment transitions from the first position toward the second position, the upper segment and the bottom segment being configured to collectively define the bottle reservoir;

a collar extendable around the seam to strengthen connection between the upper segment and the bottom segment; and

a filter assembly positionable in the reservoir, the filter assembly comprising:

a lower body defining a lower body cavity;

a lower filter positioned within the lower body cavity; and

a filter passageway disposable in fluid communication with the lower body cavity;

the upper segment, bottom segment, and filter assembly being configured such that transition of the bottom segment from the first position toward the second position urges fluid in the reservoir to flow through the lower filter and then through the filter passageway.

13. The bottle recited in claim 12 , further comprising a cap connectable to the upper segment and having a cap passageway communicable with the reservoir.

14. The bottle recited in claim 13 , wherein the cap additionally includes an inlet opening separate from the cap passageway and an inlet valve in communication with inlet opening to control fluid flow through the inlet opening.

15. The bottle recited in claim 14 , wherein the inlet valve is transitional between a closed position and an open position, the inlet valve restricting fluid flow through the inlet opening when the inlet valve is in the closed position.

16. The bottle recited in claim 15 , wherein the inlet valve is configured to assume its closed position in response to the bottom segment being transitioned to the second position, and to assume its open position in response to the bottom segment being subsequently transitioned to the first position.

17. The bottle recited in claim 13 , wherein the filter passageway is at least partially defined by a tube and an upper body, the tube being connectable to the lower body and the upper body, and the upper body being connectable to the cap.

18. The bottle recited in claim 12 , further comprising a pH modifier positionable in communication with the filter passage, the pH modifier being configured to alter a pH of a fluid flowing therethrough toward a prescribed pH value.

19. A hand squeezable drink bottle comprising:

a body defining a bottle reservoir for retaining a fluid, the body defining a bottle axis, the body having an upper segment and a bottom segment adjacent the upper segment and detachably connectable to the upper segment, the bottom segment being transitional relative to the upper segment between a first position and a second position, a portion of the bottom segment being moved toward the bottle axis as the bottom segment transitions from the first position toward the second position, the upper segment and the bottom segment being configured to collectively define the bottle reservoir;

a cap connectable to the upper segment and having a cap passageway extending therethrough communicable with the reservoir, the cap including an inlet opening extending therethrough separate from the cap passageway and an inlet valve in communication with inlet opening to control fluid flow through the inlet opening, the inlet valve being transitional between a closed position and an open position, the inlet valve restricting fluid flow through the inlet opening when the inlet valve is in the closed position; and

a filter assembly positionable in the reservoir, the filter assembly comprising:

a lower body defining a lower body cavity;

a lower filter positioned within the lower body cavity; and

a filter passageway disposable in fluid communication with the lower body cavity;

the upper segment, bottom segment, and filter assembly being configured such that transition of the bottom segment from the first position toward the second position urges fluid in the reservoir to flow through the lower filter and then through the filter passageway;
