Enviro Water Products’ water-heater shield was created to help the more than 85% of U.S. households that have hard water issues, the company notes. Issues with sediment, scale and corrosion buildup can cause significant damage to appliances such as water heaters, requiring maintenance repairs and higher energy costs. The water-heater shield is a 20-gpm unit that protects a water heater from damage by pretreating water before it enters the unit. It is equipped with a high-efficiency 5-micron filter that removes dirt, rust, silt and sediment particles down to 1/20 the size of a human hair, the company explains.
