Water purifier is a product chosen by many families, factories, apartments, schools.

Water purification technologies

Currently, there are two water purification technologies: RO and NANO technology.

  • RO (Reverse Osmosis) water purification technology 

You do not need to boil your water input. Because this technology brings a very pure sterile water source, removes all impurities such as mud, pesticides … bacteria that are harmful to the body, and replenishes essential minerals for the body, and helps prevent many diseases.

RO technology is a water filtration technology that uses filter slots of membrane filters with a size of 0.0001 micrometers. These filters can not only filter solids, heavy metal ions but also microorganisms, bacteria, etc with very small size. So this technology gives you pure water that you can drink right away without reheating the water. 

The advantage of this technology is economical because of less damage and not much maintenance.

However, there is a small disadvantage that RO filters often filter slowly, so they are easily blocked. This technology uses electricity, so it is easy to cause an explosion if you are not careful when using it.

  • NANO water purification technology

The NANO series of filters has a great advantage that water can be drunk immediately after filtering. For the safety of users, NANO water purification technology does not use electricity, the machine works thanks to the potential of the water tank. This device is easy to install and has a long lifespan.

Silver nano technology water purification

Silver nano technology water purification

Most of the brand of water purifiers use the smartest 4 in 1 filter elements, including:

– Mechanical filter: this mode helps to remove large dust particles in the incoming water source.

– Filter by adsorption: Nano filter will retain heavy metals that affect health.

– Filter by ion exchange: this is the strong and outstanding advantage of the Nano water purifier. Sediment will be treated extremely well in this filtration step.

– Filter sterilization by silver coating technology: this is the filtration stage to completely destroy 100% of harmful bacteria but still retain beneficial minerals in the water.

Buyer guide/ FAQs:

1.What is a water ionizer?

A water ionizer is not only capable of creating pure filtered water, but also capable of creating hydrogen-rich alkaline ionized water. Alkaline ionized water is water produced by electrolysis technology (also known as electrolysis alkaline ionized water) to separate water into H+ and OH+ ions, alkaline (pH>7.0) rich in micronutrients and anti-minerals oxidize.

2.How does a water ionizer work?

The operating principle of a water ionizer is based on the electric principle of analyzing water to produce alkaline and acid water. When water is put into the machine, it will go through two steps:

Step 1: Create pure water: Input water goes through a multi-level filtration system to remove impurities, dirt, bacteria, viruses, metals, etc. to become pure water source.

Step 2: Create ionized water

Purified water continues to be fed into the electronic chamber containing titanium electrode plates with water separation effect. Alkaline ionized water is generated at the cathode which then combines with positive molecular hydrogen to create hydrogen, acid water is generated at the anode.

At the end of these two steps, the water produced is a hydrogen-rich alkaline ion-electrolyte water.

3.What should you know when buying a water ionizer?

There are 7 common and important criteria that customers should consider before buying a water ionizer:

  • The origin
  • Hydrogen content in water
  • Electrode manufacturing technology
  • Reputable sales address
  • Price
  • Warranty
  • How to clean and preserve

Conclusion
