@sueinmn I have a Safe Water Products kitchen sink filter on my faucet. This filters out MAC bacteria so I feel comfortable using the water for anything including cleaning in the kitchen, washing fruits and vegetables, etc. knowing that it is MAC free water. I also clean my dishcloths, sink racks, etc. in the dishwasher on sterilize. The kitchen sink faucet filter can be purchased on Amazon. It's called the Legionela Faucet Filter Faucet Mount Water Filtration System, Tap Water Filter, Lab Tested & Certified - Log 7 Reduction. The cost is reasonable in my opinion for the peace of mind. It was very easy to attach to my faucet.
