Helps protect my appliances that use hot water
This filter does a good job reducing the hard water drops in my shower and kitchen and bath faucets. I also feel better using this, knowing my washer combo and dishwasher will also not be forming wayer deposits. I originally got this for my new hot water heater, to keep it from corroding like my last one did.
