balanced. With so many reverse osmosis water filter systems (also known as RO water filter
systems) available on the market, it’s important you choose the best brand and model for your unique

Reverse osmosis water filter systems are strong,
dependable and many prefer them over other methods of filtering. While there are many safe forms of water
filtration available, reverse osmosis continues to be one of the most popular and effective choices.
Reverse osmosis water filters have come a long way since making the adaptation from commercial systems to home
units. There are some high quality models available today, and most of the newer models have extra filtering
functions to get rid of hard to remove substances, such as fluoride, chlorine, and even some pharmaceuticals. Not
only do they offer high protection against contaminants, they are also reasonably priced within the water filter
Reverse Osmosis Water Filter Reviews – What is Reverse Osmosis?
Reverse osmosis is a water filtering process that uses a semi-permeable membrane that separates water from
unwanted particles. The water is forced through the membrane, but harmful substances are separated and
Once the water passes through the membrane, it is put through three to five additional filtering stages before
you drink it. These filters can remove most chlorine, fluoride, arsenic, copper, lead, chromium and other toxic
The final stage on some of the best reverse osmosis water filters is reserved for polishing. This filter can
give the water a better taste, and eliminate any bad smell that might come from your water source.
There are two types of RO membranes that assist in purifying your water:
1. CTA – Cellulose Triacetate membranes should be used when there is a higher concentrate
of chlorine in the water. Most water that comes from your city’s water plant is chlorinated.
2. TFC – This membrane was created by NASA. The Thin Film Composite is used when the water
is non-chlorinated, or when it contains total dissolved solids. It can also be used with chlorinated water if you
attach a carbon filter before the water reaches the membrane.

Watts Premier RO-Pure 4-Stage Reverse Osmosis System
The Watts brand creates some of the best
reverse osmosis water filter systems on the market.
The Premier RO Pure is a four stage reverse osmosis filter. The first stage collects rust, dirt and other
particles. The next stage uses a carbon filter to block out chlorine and other contaminants. These first two stages
also make your water clear and remove particles that can make your water taste bad.
During the third stage, the semi-permeable membrane removes many elements and dissolved solids. In the fourth
and final stage, the water is passed through a second carbon filter which removes anything that might have slipped
passed the first membrane.
Finally, your water makes its way to the storage tank, where it will remain until you are ready to drink it.
Many people like the fact that it is fairly easy to self-install, and delivers high quality tasting water. When the
