Compare water purifier technologies on the market
On the market today there are many types of water purifiers. Each type uses its filtration technology, such as RO, Nano, or UF water filtration technology. So which water filtration technology is considered the best today? Let’s compare the pros and cons of each technology to get the answer:
2.1. RO water filtration technology
Advantage:
It is one of the modern filtration technologies, capable of filtering impurities with extremely small sizes, only 0.1 – 0.5 nanometers. Water after filtering through RO technology water purifier has a purity of up to 99%
Diverse input water sources, can be alum water, tap water, rainwater, etc. After filtered water can be drunk directly without boiling
Defect:
In addition to filtering out impurities and harmful bacteria, RO technology water purifiers also unintentionally remove micro-minerals that are beneficial to health in water.
The amount of water discharged during the filtration process is large, causing waste
When operating, power must be provided
2.2. Nano water filtration technology
Advantage:
The design of the machine is quite compact, highly aesthetic, and can be installed anywhere in the house
Nanotechnology water purifier uses natural water pressure to push water through filter cores so it does not use electricity
During the water filtration process, the Nano water purifier also does not create wastewater
Nano water filtration technology not only filters out impurities, microorganisms, bacteria, viruses, etc. but also preserves healthy micro-minerals that exist in water.
Defect:
Usually, the filtration capacity of Nano water purifiers is not high so it is only suitable for home use
The membrane is easy to clog because the filter slot is quite large, so it has high requirements for the input water source
2.3. UF water filtration technology
Advantage:
During the filtration process, the UF technology water purifier can both remove large impurities and retain ions, minerals, and mineral salts that are beneficial to health.
Consumes little electricity and minimizes the amount of water discharged into the environment
Defect:
Impurities, algae, etc. after filtering will stay at the bottom of the filter cup, so users must regularly clean it to avoid clogging the filter head and affecting the quality of filtered water.
The filter size is large so small bacteria, impurities, etc. may not be completely filtered
- Experience in choosing to buy a water purifier
3.1. Choose to buy a water purifier based on the condition of the water source
It is important to know that on the market today no type of water purifier can be suitable for all water sources. Therefore, you should check your family’s input water source to find the right water purifier.
If it is drilled well water, it is very difficult to find a suitable water purifier. Therefore, you need to process it coarsely first and then filter it through a water purifier. If it is tap water, you can use RO or Nanotechnology water purifiers. The Russian Federation’s Geyser water purifier is recommended by many health experts because this type of machine is very suitable for tap water sources in our country. Furthermore, the machine’s price is not too high, the design is beautiful, it has a long lifespan, and rarely breaks down. The machine uses Nanofiltration technology, providing clean water while still retaining essential minerals. In particular, this type of water purifier does not use electricity and has no wastewater discharge, so it is very safe and economical.
3.2. Purpose of use, economic viability
In case you want to filter water for daily use (bathing, washing, etc.), you should choose a water purifier with high capacity, for example, a total water purifier. If for cooking, mixing, etc., priority should be given to choosing a water purifier so that the filtered water can be drunk directly at a reasonable price.
3.3. Pay attention to other factors
You should also consider some other factors when buying a water purifier, for example:
Families with young children: In this case, priority should be given to choosing a water purifier with hot and cold functions so that you can make milk, tea, etc. more conveniently.
Features and utilities: Water purifiers are equipped with many utilities such as a touch screen, core replacement indicator light, and automatic shut-off when full,… which will help make the process of using and maintaining the machine easier.
Several mineral filter cores (RO water purifier): After filtering water through the RO membrane, impurities, and bacteria will be removed, equivalent to distilled water. The rear filter cores (cores 5 – 10) will add beneficial minerals to the water.
Brand: You should choose to buy water purifiers from reputable brands such as Geyser, Karofi, Panasonic,… and buy at a reliable address to be able to buy it.
Through the above article, you probably already know whether you should buy a water purifier or not. Buying a water purifier today is really necessary and important to care for and protect the health of yourself and your family. Especially for families living in areas with polluted water sources, it is even more important to buy a quality water purifier.
