ABSTRACT:
A personal portable filtration device for removing contaminants from water. In one form, the filtration device is attachable to an ordinary drinking straw, and in another form the filtration device is attachable to an enlarged section of a tubular member. In a first embodiment of the first form, the drinking straw is insertable at one end into an opening in the filter device, whereby the filter device is applied externally of the straw, and in another embodiment the filter device is sized and shaped for insertion into an end of the straw. In one embodiment of the second form, the filter device is received in an enlargement at one end of the tubular member, and in another embodiment is received in an enlargement between and spaced from the ends of the tubular member. In all forms of the invention, the filter device may consist of one or more filter media for removing one or more impurities from water, including particulate matter, objectionable odors and tastes, harmful chemicals and/or metals, microorganisms, and the like. The filter device may be replaceable so that a fresh filter device can be readily substituted for one that is no longer serviceable, and the ability to use it with an ordinary drinking straw makes it particularly convenient to use.
