The best way to decide whether a whole house water filter or purification system is best is to know what’s in your water. A water testing lab can test for a range of contaminants in your water and give you a report showing the levels of these contaminants. An important thing to consider is which impurities you need to be removed and their impact.
While waste purifiers remove all the minerals from your water which can be good if you have hard water problems, there can be health effects as well. Minerals such as calcium, magnesium, potassium and iron are important to the body, so water should have a minimum level of these essential minerals. With that said, water filtration will keep these minerals in your water, at the expense of being slightly less effective. If you choose water purification methods, it is important to replace these lost minerals with a remineralizer.
