How to buy a water purifier
Details

How much water pressure is required for a water purifier?

The purifier can withstand the water pressure of 4 Bar, while the pressure of tap water is usually not more than 1 - 1.5 Bar. However, when a water purifier is installed in a customer's house with a water pump or in a condominium, there will be more water pressure. It is recommended to measure the water pressure before installation. If there is a high water pressure (from about 3 bar or more), it is recommended to install a water pressure reducing valve to reduce the expansion of the water filtration cylinders that has to withstand retaining water pressure for a long time. As for the problem of high retaining pressure in the cylinders, at first there might not be a leak in the cylinders. When they are used for a longer time, the retaining pressure will push the cylinders to expand. Therefore, when a water purifier is installed with high-pressure water, it is also desirable to install a set of pressure relief.

Water purifier standards that you need to know

Water is considered an important factor in the lives of humans; therefore, we should choose to drink clean and safe water. Water purifiers are produced as device to help remove contaminants from drinking water and the installation of a water purifier for home use is the best and easiest way to filter and clean water. Therefore, choosing a water purifier for home use is important. However, the selected water purifier should be certified and meet internationally recognized standards. Before deciding to buy a water purifier, we should first know the water purifier standard and its evaluation criteria. NSF International follows American National Standards Institute (ANSI) to sets NSF/ANSI standards for properly evaluating efficiency of water purifiers; and they have been accepted in many countries. NSF International analyzes the following factors for certifying water purifiers as follows: Physical Effects: Test the efficiency of water purifiers in reducing the amount of contaminants that affect taste, odor and clarity of drinking water, Health Effects: Test the efficiency of water purifiers in reducing the environmental contaminants including lead, asbestos, volatile organic compounds and pesticides in drinking water, Ultraviolet light treatment on microbiological safety: Test on a water purifier that uses ultraviolet light to eliminate microorganisms in drinking water.

Is the water purifier suited for water for use necessary for tap water?

Nowadays, most houses have water tanks to store water for use all the time, but these large tanks often are not cleaned; contaminants get into the water and accumulate inside the tanks. After a long time, these contaminants enter a house and cause a blockage in faucets and electrical appliances and accumulation of stains on various sanitary wares. The installation of a water purifier suited for water for use reduces the accumulation of these impurities and prolongs the cleaning periodicity of the water tank.

How is the use of an RO system different from those of regular filtration?

RO filtration system is intended to separate out the high concentrations of solutes in the water. It is often used in groundwater source areas, coastal areas or areas with brackish water problems in order to separate the solutes to leave water suitable for drinking; whereas filtration in other systems cannot do.

After using a water purifier for some time, although it is yet not time to change its filter, why is the water running slowly?

Each area has different water conditions. Some areas may have more turbid water than others. As a result, the filter becomes clogged faster than its specified service life. In this regard, it may be advisable to install an additional coarse filter to prolong the service life of the filter.

Why does water smell weird when I turn on my faucet after not being used for a long time?

When a water purifier is not used, there will be remaining water in the cylinders. When there is no water to replace it for a long time, it may cause odors, which is normal. Therefore, before water filtration, you should drain this water for about 1-2 minutes, the smell will disappear. If it does not disappear, the filter may expire or the filtering efficiency of the filter may deteriorate. Therefore, the filter should be replaced.

How much water pressure is required for a water purifier?

The purifier can withstand the water pressure of 4 Bar, while the pressure of tap water is usually not more than 1 - 1.5 Bar. However, when a water purifier is installed in a customer's house with a water pump or in a condominium, there will be more water pressure. It is recommended to measure the water pressure before installation. If there is a high water pressure (from about 3 bar or more), it is recommended to install a water pressure reducing valve to reduce the expansion of the water filtration cylinders that has to withstand retaining water pressure for a long time. As for the problem of high retaining pressure in the cylinders, at first there might not be a leak in the cylinders; but when they are used for a longer time, the retaining pressure will push the cylinders to expand. Therefore, when a water purifier is installed with high-pressure water, it is also desirable to install a set of pressure relief.

Why does filtered water smell like chlorine or have a weird smell?

Carbon filter is very effective at adsorbing odors and chemicals. Therefore, if the water that passes through a water purifier has a smell, it means that the filter has deteriorated from long use, or there is a crack inside the filter, such that the water that does not pass through adsorbing carbon comes out, or the water contains a lot of chlorine, thus making the filter short-lived. It is recommended to install additional carbon filters or replace the carbon filters when there is an odor or use an RO system instead. However, tap water will come with chlorine to kill germs or there may be rust from the plumbing. Some seasons the water may taste salty, and sometimes there may be foreign matter from broken plumbing or plumbing repairs.

When the filtered water is chilled, sometimes I see white flakes in the water

In the production of activated carbon filters, high temperature heat is used to form a cartridge such that the surface of the carbon filter becomes more alkaline; and when the water is chilled, white flakes will appear. The alkalinity of this carbon will gradually decrease by regular use of it. As for a way of solving the problem, when a new filter is used, the filtered water should be discarded for about 10 - 15 minutes such that the carbon filter will adjusted to the neutral pH range.

What caused the water in a bottle to turn green?

Problems of this nature are often caused by a container which has been contaminated or has been reused repeatedly. The reaction may be catalyzed by the environment such as suitable sunlight or temperature and it will cause algae to occur. It is recommended to use containers only for water and keep them in a dry place and out of the sunlight. Moreover, a lot of water should not be stored at a time, it is more appropriate to use a water purifier regularly.

What are the consequences if I use the filter beyond the normal replacement period?

As for the recommended filter replacement period, there is a test that it is an appropriate period. Using a filter beyond the replacement period may cause us to drink water from a filter with deteriorating performance, and the water is not as clean as it should be.

How to clean for each filters types?

- The PP filter can be cleaned by removing it and spraying water to clean its exterior surface. Do not use hard brushes or scouring pads on it because they could easily damage its surface. - The 0.5 and 0.3 micron carbon block filter can be cleaned by removing it, spraying water to clean its exterior surface, using a soft-bristled brush, such as a toothbrush, to scrub the dirty areas, and then assembling it in place. - The resin filter can be cleaned by soaking the filter in 10% saline water (100 g salt / 1 liter of water), shaking the resin beads inside such that they rub against one another for discharging ions in order to restore filter efficiency and soaking time takes about 25 – 30 minutes, then rinsing it with water to remove the stinging saltiness and assembling it in place and checking whether the filter is inserted correctly.
