How safe are home water filters anyway? The perception is that these gravity fed water filters clean your tap water, but perception and reality are different. The main concern is heavy metal contaminants easily removed by reverse osmosis or steam distillation such as arsenic, lead, cesium and aluminum as examples. An independent test showed some alarming results.
Most heavy metals in our tap water cannot be detected simply by looking at the water, tasting it or by its smell.
The only way to detect heavy metals in your drinking water is through a water test.
The easiest solution however is installing a water filteration system such as reverse osmosis which removes 99% of the total dissolved solids and heavy metals, or by using a water distiller.
