Fluid purification device

A water purification system comprising:

• a tank having an interior space;
• a cover having a bore, the cover being removably coupled to the tank;
• a lever movable between a first position and a second position coupled to the cover;
• a media container having a ring assembly, the media container disposable within the interior space;
• and
• a valve having an upper valve member and a lower valve member each at least partially disposed within the bore of the cover and a biasing member disposed between the upper valve member and the lower valve member;
• wherein the upper valve member and the bore define a first fluid path from the interior space of the tank to an atmosphere and the upper valve member and the lower valve member define a second fluid path from the interior space of the tank to the atmosphere;
• wherein the upper valve member is movable between a first position unsealing the first fluid path and a second position sealing the first fluid path;
• wherein the lower valve member is movable between a third position unsealing the second fluid path and a fourth position sealing the second fluid path;
• wherein the biasing member biases the upper valve member toward the second position and the lower valve member toward the third position;
• wherein when the media container is disposed within the interior space, the ring assembly engages and biases the lower valve member into the fourth position;
• wherein when the lever is in the second position, the lever engages and biases the upper valve member into the first position.
