Here is an excerpt:
In addition, EPA is concerned that the claims and advertisements for these filters may imply that they can effectively purify raw water, when in fact they cannot. EPA officials recommend that consumers cease using the two filters, which are sold throughout the United States and internationally, and dispose of them immediately because they may pose a risk to public health.
The drinking water filters consist of a straw (AccuFilter Straw, EPA Reg. No. 64906-1) and a bottle (AccuFilter Bottle, EPA Reg. No. 64906-2). Each device is equipped with a silver-impregnated activated carbon filter designed to filter out sources of odor and taste from drinking water (EPA's registration approved the filters for use on potable water only). The registrant is AccuFilter International Inc., 9915 Southwest Arctic Drive, Beaverton, Ore. 97005.

The principal owner of AccuFilter International Inc., Bruce D. Spangrud, was indicted on Sept. 28, l994, by a Federal Grand Jury on two felony charges that he submitted false statements to obtain an EPA pesticide registration that allows him to sell the drinking water filtration devices. A criminal trial is scheduled in the Federal District Court in Portland on Dec. 20.


So in short, no, get rid of it.
