Pump Filters
The best personal water filters on the market are the type that requires pressure to work-the Pump Filters. Pressure is typically created by pumping a handle, which forces water through the filter element. Filter elements usually utilize permeable ceramic or hollow fiber membrane elements, and sometimes incorporate a charcoal element which is used to remove bad odor as an additional improvement of the general function.
Ceramic Filter
Membrane filter
Ceramic filters element eventually clog and they must be cleaned periodically to maintain efficiency.
Membrane filter element also clogs, but they can be cleaned much more easily by back flush device along with the filter itself.
Another consideration is how water gets from the filter to your bottle. Most filters use a small hose that secures to the outflow end of the filter, with the end of the hose sitting inside the water bottle. Devices like this require the bottle to be placed on a flat, level surface that does not allow the possibility of the bottle being accidentally kicked over in the process of filling it.
