Maintaining under the sink filter

I've had two filters in my house for the past 15 years. I've never bleached the housings. I do wipe them out with a paper towel. It is possible that bacteria will grow in the filter over time though. If you want to be safe, give the housing a bleach rinse, but I don't thing you'd gain anything over an hour. I've be afraid that the bleach over time would affect the housing.

A bleach and water solution, wash well and rinse. An hour is not necessary. Would you suspect a service person would spend and hour bleaching a filter housing?

I kind of thought the bleach would get into the plastic housing. I usually wipe out my Britta pitcher after a while.

The clerk obviously knows more than the manufacturer, so you better bleach. I have never done mine, but I like to live dangerously.
