Optional Add-Ons
Ice Maker Kit (ICEK)
The Ice Maker Kit (model#: iSpring
ICEK) can be purchased separately to
feed RO water to your refrigerator for
crystal clear ice cubes and great tasting
water. If you choose to hook up the
system to your refrigerator output, it can
take the place of primary output over the
RO faucet.
Section 2: Knowledge Base and FAQ
What Is Reverse Osmosis?
Reverse osmosis, also known as hyper filtration, is a membrane filtration process that separates
undesirable contaminants from water by using pressure to force the water molecules through a
semi-permeable membrane. This process is called "reverse" osmosis because the pressure forces the
water to flow in the reverse direction (from the concentrated solution to the dilute solution) to the
flow direction (from the dilute to the concentrated) in the process of natural osmosis. Reverse
osmosis is used to purify water and remove salts and other impurities in order to improve the color,
taste, odor and/or properties of your water. RO filtration can remove up to 99% of most
contaminants including arsenic, nitrates, radium, chromium, fluoride, and dissolved solids such as
sodium, calcium, iron, magnesium, copper, etc.
How Effective Is Reverse Osmosis Filtration?
Reverse osmosis filtration is by far the most effective and economic method of water filtration. It
filters water by squeezing water through a semi-permeable membrane, which is rated at 0.0001
micron (equal to 0.00000004 inch). This is the same technology used to make bottled drinking
water. It is also the most used technology for desalinating seawater, making it into drinking water.
What is a TDS meter?
A TDS meter is a handheld Total Dissolved Solids tester. TDS is the total weight of all solids
dissolved in a given volume of water. It is expressed in parts per million (PPM). With a TDS meter,
you can compare the quality of the RO water with your original source water, and also periodically
check the RO water to know when it’s time to change the filters.
