| Q:
My tap water is already safe
and clean. Why does it still need to be filtered? |
A:
The quality of your tap water may not be as clean as you think. Rivers,
lakes, streams and reservoir catchment areas are increasingly being
contaminated by industrial waste and environmental pollution. Also,
faced with dwindling supplies of fresh, pure water, many cities have
turned to using recycled water, including the waste that is flushed
down your toilet and then chemically treated and used in your drinking
water supply.
Water treatment plants generally try to make your water safe, but it is
not possible to get rid of all contaminants. Enroute to your home or
building, the water passes through hundreds of kilometres of aging
water pipes and infrastructure and may absorb impurities along the way.
So why take the risk and drink unfiltered water? Buy
your UltraPure/ Watts water filter today!

| Q:
Are there contaminants in our water? What
do UltraPure and
Watts
water
filters
remove from our water? |
A:
All water contain some amount of contaminants depending on its source.
Contamination occurs through industrial and agricultural pollution,
chemicals and other environmental waste. For example:
- Sediment, sand, silt, rust and scale particles which may come from
the hundreds of kilometers of aging pipes and infrastructure that
transport water from the treatment plant to your tap.
- Bacteria (including E.coli, Legionella, Salmonella), algae, fungi and
cysts (including Cryptosporidium and Giardia), whose presence in water
indicates contamination with sewage, faeces, human and animal waste.
- Heavy metals (including cadmium, copper, lead, mercury and zinc) and
Volatile Organic Compounds (including pesticides, benzene and toluene)
caused by air emissions from mining and industrial plants, accidental
leakage or illegal dumping of waste by irresponsible organizations, and
even not getting rid of everyday items in your house properly, like
paint, cleaning solvents and motor oil.
- Chlorine from the water treatment plant, and its by-products like
Trihalomethanes (THMs) which may increase your risk of getting cancer.
UltraPure and Watts water filters effectively remove all these
contaminants,
providing you and your family with safe and clean water.

| Q:
What are
Point-of-Use (POU) and Point-of-Entry (POE) water filters? |
A:
Point-of-Use (POU) water filters are connected to a single tap, like
the kitchen tap at home, in the office pantry, or individual taps in a
restaurant or food court. They filter water at a specific tap,
supplying clean water for drinking, cooking and washing. Counter-top
filters and Under-sink filters are POU water filters.
Point-of-Entry (POE) water filters are connected after the main water
supply. They filter and supply clean water to every tap in the entire
house, office, factory, restaurant and food
court.
Where possible, instal both POU and POE water filters for double
protection.

| Q: What
is Reverse Osmosis (RO)? |
A:
Reverse Osmosis (RO) is a process by which water molecules are forced
through a 0.0001 micron semi-permeable membrane by water pressure. Long
sheets of membrane are sandwiched together and rolled up around a
hollow central tube in spiral fashion, commonly referred to as spiral
wound membrane. RO membranes are available in different sizes for
processing different quantities of water.
The RO membrane is housed in a housing so that pressure can be
maintained on its surface. This pressure forces the water through the
membrane, separating it from the unwanted substances like dissolved
chemicals, heavy metals, suspended solids, arsenic, salts and
other impurities. These unwanted substances are diverted to a waste
drain so that they do not build up in the system, thus keeping the RO
membrane clean.

| Q:
What is
Ultrafiltration membrane? |
A:
Hollow fibre membranes are made from polymeric material and resemble
straight lengths of noodles which are hollow on the inside. On the
surface are very tiny holes or pores which run over the entire length
of the noodles. These pores, which are not visible to the naked eye,
can only be seen using high powered special microscope. The pores of
the Ultrafiltration membrane range from 0.01 to 0.1 micron in size. For
comparison, the full-stop at the end of this sentence is 500 microns.
The pores have the ability to stop the passage of particles, turbidity
and pathogens such as bacteria, algae, cysts and parasites but allow
water and natural, healthy essential minerals such as calcium,
magnesium and potassium to flow through. The result is a consistent
supply of high quality treated water.

| Q:
What is Activated Carbon? |
A:
Activated carbon is activated charcoal or coal which has been processed
to make it extremely porous and thus to have a very large surface area
available for adsorption. It removes heavy metals, hormones, volatile
organic
compounds and chlorine, providing you and your family with clean water
that eliminates odour and improves taste.

| Q:
Do UltraPure's range of water filters use any chemicals for filtration? |
A:
No, there are no chemicals used in UltraPure's range of water
filters.

| Q:
Why is there cloudy water coming out from my new filter? |
A:
The cartridge in every new filter or after a new cartridge change, is
full of air. As water flows into the cartridge, small air bubbles are
trapped and then released, resulting in the
cloudy water that you see.
Before first use, run water for 5 to 10 minutes in filtered water
position
to flush out the air bubbles in the filter cartridge. Water filter is
fully flushed when the water level in the housing does not drop after
tap is turned off.
You may use this flushed water to water plants and do other household
chores.

| Q:
How often do I
need to change the filter cartridge? |
A:
Several factors determine how long the filter cartridge will last.
These include:
- Quality of your municipal water
- Levels of sediment and other undesirable substances in the water in
your area/location. They can range from aging water pipes and
infrastructure to pollutants in the environment.
- Amount of water you use
You should change your filter cartridge when the water flow drops or at
least every 6 to 12 months.

| Q:
Why is there a
need to replace the filter cartridges
every 6 to 12 months? |
A:
All filters have a limited lifespan. Contaminants are either trapped in
the pores of the filter or adhere to the surface. Eventually, the
filters become clogged with debris and are no longer effective in
filtering water. When this occurs, bacteria may grow and multiply on
the filter itself, especially activated carbon filters as they offer
micro-organisms a favourable area for growth on their outer surface.
This could then find its way back into the system and pollute the
water. In order to prevent this, it is advisable to replace the
filter cartridges every 6 to 12 months.
