We have a private well with a very high mineral content. Needless to say it is also high in turbidity. During construction we had a dual filtration system installed and are using both the 810 and 811 filters along with an electrolysis called a 'Scale Blaster'. Unlike our neighbors, who also have wells, we have had no lime, scale or sediment build up on our faucets or appliances. We have been successful in advising our neighbors of the system and they have also had great results. Our home as well as our appliances are now 18 years old and doing just fine. Most of our neighbors, some with even newer homes, have had to replace faucets, valves and even appliances due to unwanted buildl-up. Maybe one day they will make the minor investment in a filtration system. By the way, changing filters at 6 month intervals has been just fine for our conditions. I might add that we use a Pure PH21200 for our refrigerator filter which provides us excellent bottled water quality and taste.
