Pure Water - Distilled Water, Steam Distillation for the purest drinking water

Filters and Reverse Osmosis are barriers

Filters are simply a barrier placed in a high pressure water line. Raw water is on one side under pressure. 'Filtered' water is on the other side. Barrier filters include reverse osmosis (R.O.), carbon filters, sand filters and ceramic filters.

Filters typically can not produce high-purity water over time.

All Filters deteriorate, as they do, the quality of water they produce also declines. This is why you need to change filters frequently. (Most consumers do not!!)

Filters can provide inconsistent results based on a number of factors including water temperature, quality of the raw water, chemicals in the water, age of the filter, bacteria, etc.

Filters do not kill biological contaminants . Filters cannot offer solid protection against biological contaminants. This is why FEMA and the American Red Cross don't endorse any type of filter during a biological outbreak (these organizations do endorse steam-distillation).

Filters have a problem with bacteria creep . One of the most serious problems with filters is bacteria creep. This is when trapped bacteria actually grows and multiplies within the filter and can grow through the filter causing ruptures and bacterial contamination.

Filters can cause direct contamination . The filter is a barrier between the raw and filtered water. If this barrier fails for any reason, there will be direct contamination of the filtered water. In contrast, steam-distillation boils the water and has an air gap between the raw and pure water.
