I have to surmise that it's better than nothing. The filter is used in a pop-up camping trailer. I remove the filter prior to sanitizing and flushing-out the fresh water tank, hot water heater tank, and the pump, faucets, and supply lines. The filter does not eliminate the post-rinse leftover odor and taste of the chlorine bleach sanitizer, though perhaps it could be worse without the filter. My household water does not ordinarily have any objectionable odors or tastes. I also remove the filter when emptying out the camper water system as winter approaches.
