What is the difference between purified water, pure water and soft water

Update time : 2021-09-26 14:09:00

We all know that there are many types of water purifiers, and the water purified by each type of water purifier is different. Purified water can be divided into three types of water quality: purified water, pure water and soft water according to the degree of purification. What's the difference, I will tell you everything today!

1. Water purification
Water that does not contain any harmful substances, antibiotics, residual chlorine, heavy metals, inorganic salts, any additives and various impurities, we call it purified water.

advantage:
There are many types of water purifiers that produce purified water, including sand filter, activated carbon, ultrafiltration, etc., which can purify the water to a certain extent, remove suspended solids in the water and organic compounds, inorganic compounds, heavy metals, bacteria, etc. that are harmful to the human body. , While retaining the trace elements and minerals needed by the human body, it can be directly consumed raw.

insufficient:
Although the water purifier can purify the water source to a certain extent and can remove silt and rust, it cannot completely remove scale, bacteria, and viruses. It belongs to primary filtration. A more advanced water purifier can only remove some bacteria, viruses and heavy metals, and cannot achieve the purification level of pure water, and cannot guarantee water quality for heavily polluted water sources.

Be applicable:
Purified water is suitable for drinking and cannot be used for washing and showering. For areas where water pollution is not serious and the removal of scale is not considered, it is suitable for installing water purifiers and also suitable for use with water softeners.

2. Pure water
Pure water, also known as purified water, refers to water that meets the hygienic standards of drinking water as raw water, and is prepared through appropriate processing methods, sealed in a container, and does not contain any additives, is colorless and transparent, and can be directly drinkable. .

advantage:
Purified water is produced by the water purifier using the world's advanced ultra-thin film reverse osmosis water treatment technology. The filtration rate of the reverse osmosis membrane can reach more than 98.5%, and the filtration rate of bacteria, E. coli, heavy metals and other substances can reach 100% , The pure water produced by the pure water machine at home is more fresh and hygienic than bottled water, suitable for raw drinking and cooking; bathing with pure water can moisturize the skin; because calcium and magnesium are removed, it is also softened water, boil a kettle or electric The thermos bottle will not be scaled, and is especially suitable for the water needed by small household appliances such as humidifiers, steam irons, and beauty instruments.

insufficient:
Some people think that purified water is not suitable for long-term drinking. Although purified water removes bacteria, viruses, heavy metals and other pollutants in the water, and basically ensures the safety of drinking water, it also removes trace elements and minerals that are beneficial to the human body. Weak acidity, long-term drinking will affect the body's electrolyte acid-base balance, leading to lack of nutrition and suffering from calcium deficiency, so it is not suitable for daily drinking water. Also, although it is said that the skin is moisturized with pure water, the water flow from the pure water machine is very small, so it can only be used to wash the face and cannot be used in the shower.

Be applicable:
It is suitable for areas with serious water pollution, and it is best to install water purifiers in high-rise buildings with water storage tanks. Although it is said that pure water is not suitable for long-term drinking, if the water source is seriously polluted, life-saving is still important in the two choices of poisoning and nutrition. If the nutrition is insufficient, it can be supplemented by other methods.

3. Soft water
Soft water means that the hardness of water is less than 8 degrees, and it contains no or less soluble calcium and magnesium compounds. In natural water, rain and snow are soft water. Spring, stream, and river water are temporarily hard water, part of the groundwater is hard water, and distilled water is artificially processed soft water.

advantage:
Soft water uses ion resin exchange technology through a water softener to remove calcium and magnesium ions from the water, which can completely remove scale. The softened water has many benefits:

Soft water can beautify hair, make skin soft and smooth, promote skin metabolism, and make hair soft and shiny;

In terms of health care, it can reduce constipation and prevent the occurrence of stone diseases; washing vegetables and cooking rice can shorten the time, the rice is soft and smooth, does not damage the nutrition of vegetables, and maintains a fresh taste;

Soft water for washing makes the tableware cleaner, the clothes washed out are soft and comfortable, prevent clothes from static electricity, and save the amount of detergent;

The effect of raising fish and flowers is good;

Because the treated soft water will not block and produce scale, it has high heating efficiency and energy saving. It is especially suitable for water heaters, massage bathtubs, independent heating stoves and so on. The water softener does not need to change the core, just regularly add large grains of coarse salt to the salt tank.

insufficient:
According to water nutrition experts, tap water with a water hardness between 200 degrees and 300 degrees is qualified water. The soft water produced by water softeners on the market removes calcium and magnesium ions, which makes the content of sodium ions higher, and is suitable for long-term drinking. It will have an adverse effect on the human body, especially for patients with heart disease and hypertension. In addition, the water softener cannot remove the residual chlorine and organic matter in the water, so if the water hardness does not exceed the standard, it is best to use soft water as domestic water instead of drinking water.

Be applicable:
Because the soft water removes the alkali, the water has good conductivity, and the pipe wall does not form scale, which can save gas and make the heating hotter. It is not suitable for gas wall-hung boilers and gas water heaters, because the alkali content in the soft water is extremely low. Damage the gas wall-hung boiler and gas water heater, completely solve the problem of blocking the normal use of water facilities due to the generation of scale, and can prolong the service life of the equipment. Especially for households with gas heating, it is best to install a water softener, which can not only improve the heating effect, but also save heating costs.

In fact, so many kinds of water purification equipment are nothing more than giving customers more choices to choose water purification equipment suitable for their homes. Then everyone can understand the water purification equipment and prices according to the introduction of the editor, and then buy water purification equipment. Have a judgement when it comes to the device.

Trivia丨Extend the life of the RO membrane 6 practical tips

Apr .29.2025

As the “heart” of the water purifier, the RO membrane directly determines the water quality and the cost of replacing the core (the price of a single unit is usually in the range of 50-120 U.S. dollars). But 90% of users do not know: scientific maintenance can make RO membrane life 1-2 years longer! Today we are from 5 key dimensions, hand in hand to teach you to guard this “water purification engine”.

Why is your membrane product losing treatment capacity and needing frequent replacement?

Apr .29.2025

After the membrane system has been running for a period of time, sometimes the treatment capacity decreases significantly and fails to reach the designed capacity. The reasons for this phenomenon are mainly related to the working environment of the membrane system, selection and design, installation and construction, operation and management, and the performance of membrane products.

How much of a difference is there between drinking the same water, using a water purifier and bottled water?

Apr .28.2025

Simply on the point of “drinking water”, whether it is filtered water from a water purifier or bottled water, there is not much difference. After all, it's all “H₂O”. The only difference is that the water inside the “impurities” (including minerals) is different. This difference is reflected in the type of impurities, the amount of a particular impurity.

Filter cartridge overdue for use? Water purifiers may be ‘feeding bacteria’!

Apr .28.2025

Friends, how long has your water purifier filter not been changed? Is not think as long as there is clean water flow out, is equal to everything is fine? In fact, this idea really have to change! Because the water purifier is not a ‘perpetual motion machine’, the cartridge is its core components, once the overdue use, not only lose the filtering function, but also may become a breeding ground for bacteria.
