The present invention is a portable water filtration/purification system that may be used for educational purposes. It includes a plurality of stackable filtration/purification housings, each of which accommodates a different type of water filtration/purification subsystem. A pressurization cap connectable to each housing provides for pressurizing one, several or all housings stacked in a particular combination or sub-combination. The housings may be color-coded for easy identification of each the type of filter within a particular housing. The water filters or purifiers in the various housing may include, but are not limited to, a sediment filter, a carbon filter, a reverse osmosis filter, a forward osmosis filter, a chemical purifier (or purification sub-system), and/or an ultraviolet light water purifier (or purification sub-system).
