A.1 Pre-Filters:
The pre-filters have two purposes, one is to clean the water for better
consumption, and the second is to prevent the RO membrane from being
fouled. The first stage filter removes sediment materials such as sand, rust,
pipe scale, and dirt. It is made of a spun polypropylene material that will take
out particles down to 5 -microns.
The water then goes to the carbon block filter, which is important for two
reasons. First, it takes out 90% of the chlorine in the water thereby protecting
the RO membrane from damage by the presence of chlorine. It also removes
the taste of the chlorine, as well as other tastes and odors that affect the
drinking water changing the flavor of tea, coffee or other mixed drinks. (The
carbon accomplishes this by adsorption on its surface). This is a chemical/
mechanical process unique to carbon that has been activated -made to have
high surface area. The second reason is that the carbon block also takes
out VOCs (volatile organic chemicals) which are contaminants from industrial
pollution. Claims for reduction of chlorine and VOCs have not yet been
certified by the Water Quality Association.
A.2 The Reverse Osmosis Membrane:
This is the heart of the Machine, and the great protector. The membrane is
a replication of human or animal stomach tissue, which permits the water
molecule to pass through, but holds the dissolved molecules back. This
occurs naturally by osmotic pressure developed because of the content of
dissolved solids. To make this happen with the RO membrane we reverse the
osmotic pressure by applying pressure to the water (reversing the process of
