such the 2010 earthquake Haiti. The actual mechanism of the can or bottle is very simple. It uses a disposable carbon filter that can process 0.71 liters of water in 20 seconds. To filter the water, one puts contaminated water in the back of the bottle, and then screws the lid on. The lid has a built in pump that is operated manually. The pumping action forces the contaminated water through the nano- filter, and safe drinking water collects in another chamber in the bottle. The drinker then opens the top of the bottle, from which safe drinking water comes out.
