There are two ways of evaluating how much purifier you need, and you should consider both ways. The first way is comparing your Tap Water Profile which is based on the following factors:
- The test report from your public water utility (or on your own test results if you have a well or other private system)
- Whether your public utility is in a city or large town as opposed to a small town
- Whether your public utility get its water from underground or surface water (or whether your private source is a well or surface water)
- The region where you live
Your Tap Water Profile helps you keep track of what you know about your tap water. That leaves what is unknown. The second way of looking at how much purifier you need is to realize that of the estimated eighty thousand chemicals in commercial use today, many of which have been found in water supplies, only a hundred or so are regularly tested for.
From this perspective, the safest course is to get a purifier, or water filtration system, that will remove any specific pollutants that you know are in (or have been in) your tap water, and that will also remove the most of all the many kinds of pollutants that may be in your water.
