high quality under sink water filter

a). Look for California Certification...the California Department of Health has the strictest criteria for certifying water filters, ensuring maximum performance.

b). Make sure the under water sink filter removes all impurities, including chlorine, lead, cysts, THMs, VOCs, lindane, alachlor, atrizine, benzene and MTBE. Most filters on the market will not remove all of these impurities.

c). Lastly, ensure that natural trace minerals are not removed, as they provide health benefits. Only contaminants and impurities should be taken out.
