Water Distillers
-
In the distillation process, water is heated until it boils and evaporates to gas form. The water steam then condenses to a liquid in a separate container, leaving behind heavy metals and contaminants. However, this process does not remove all harmful substances, such as chlorine.
Reverse Osmosis
-
In reverse osmosis, water is diverted against its natural flow path under pressure. The water passes through a very fine membrane, which acts as a filter. This removes heavy metals and minerals, but is not as effective at removing chlorine and other synthetic chemicals.
Carbon Filters
-
Carbon filters are by far the most popular filters. This process filters out the majority of unwanted contaminants, including chlorine, heavy metals and synthetics, while allowing minerals like calcium and magnesium to pass through a porous, charcoal-activated filter.
Filter Mediums
-
The distillation method is available in tabletop or freestanding models. Most reverse osmosis systems require under-the-sink installation, and can be costly. Carbon filters are available as pitchers, mountable faucets, under-the-sink installs and even whole house filters.
Considerations
-
There are many things to consider when choosing a home water purification system. You have to consider your tap water quality and contaminants, initial cost, installation, replacement expenditures, and your personal water requirements and desires. Thoroughly research brands before purchase.
