What this site is
ClearTapCall is a referral service, not a contractor and not a laboratory. We connect homeowners with independent contractors for filtration and treatment installation. Contractors are required to hold whatever credential their state or municipality demands, and treatment equipment plumbed into a supply is often a permitted alteration — ask to see the permit. We carry out no work, we sell no equipment, we test no water, we do not set prices, and we never charge homeowners anything. Nothing here is a statement about the water at any address, and no page recommends a product.Middle River in numbers

Cartridges are a running cost
A filter that is not changed on schedule is worse than no filter at all. Factor the cartridges in before comparing two installations.
What the annual report tells you
Every public system publishes a consumer confidence report. It covers the supply as it leaves the system, which is not the same as the water at your tap after it has crossed your own pipe.
