Compare pure drinking water and alkaline ionized water in detail for each type

Water is an essential ingredient for life, playing an important role in many body activities. Pure drinking water and alkaline ionized water are two popular types of water on the market today, offering distinct advantages and disadvantages. In this article, SAPUWA will compare pure drinking water and alkaline ionized water in detail to help you make the most suitable choice for your health.

1. Outstanding characteristics of pure drinking water

Outstanding characteristics of pure drinking water

Pure drinking water is water that has had most impurities and bacteria removed through today's advanced filtration methods. Purified water will be a popular choice for daily needs due to its ease of access.

1.1. Characteristic

  • Has a neutral pH level of pH 7.0, eliminating almost 99% of impurities and harmful bacteria, ensuring health safety when used.
  • It has a refreshing taste, is easy to drink and is suitable for all tastes and needs of consumers.
  • Purified water can be easily found at grocery stores, convenience stores, supermarkets or ordered online.

1.2. Advantages and disadvantages of purified water


  • Pure water has been processed through a modern filtration process, ensuring safety for health. In particular, SAPUWA's purified water through ion treatment technologies still retains some beneficial minerals and that is also what differentiates SAPUWA in the market today.
  • Pure drinking water is cheaper than other bottled water, suitable for everyone.
  • Contains no minerals or other additives, completely suitable for all ages, including infants and pregnant women.
  • Helps regulate body temperature, increase metabolism, support effective digestion and nutrient absorption.


  • Pure water should be used with a healthy diet and daily lifestyle to bring the best effects.

2. Characteristics of alkaline ionized drinking water

Characteristics of alkaline ionized drinking water

Alkaline ionized water is water created by electrolysis of water. The electrolysis process helps change the molecular structure of water, creating water that is slightly alkaline and rich in active hydrogen.

2.1. Characteristic features

  • The pH of current alkaline ionized water is from 8.5 - 9.5. For SAPUWA's alkaline ionized drinking water, the pH will range from 9.0 to 9.5 depending on the environment, with a difference of 0.5.
  • Alkaline ionized water contains abundant active hydrogen with powerful antioxidant properties, helping to protect cells from damage, increase resistance and strengthen the immune system.
  • Rich in essential minerals such as calcium, magnesium, potassium,... helps the body absorb better, supporting the digestive system to function effectively.

2.2. Advantages and disadvantages of alkaline ionized water


  • Due to its mild alkaline nature, alkaline ionized drinking water helps neutralize and balance excess acid in the body.
  • Alkaline ionized water is completely filtered to remove impurities, bacteria, viruses and toxic substances, while retaining beneficial minerals to help the body always be fully compensated with nutrients, increase resistance and support. functions work effectively.
  • Alkaline ionized water contains high levels of hydrogen, which can be considered a "natural antioxidant". Thanks to that, alkaline ionized water contributes to slowing down the aging process, giving you youthful skin and a healthy body.
  • Alkaline ionized water brings the body to an ideal pH balance, supporting effective treatment of acid-related diseases and enhancing resistance.
  • Due to their microscopic size, alkaline ionized water molecules easily penetrate the blood and cells, helping the body absorb nutrients faster and more effectively. At the same time, it increases the flavor of food, helping you have delicious and nutritious meals.


  • Excessive use of alkaline ionized water causes electrolyte disorders, which can lead to diseases such as diarrhea, nausea and hypokalemia.
  • Alkaline ionized water packaged in bottles can change its properties when exposed to high temperatures or low humidity, affecting water quality.
  • Alkaline ionized water often costs more than other types of regular water due to the more complicated treatment and electrolysis process.

3. Compare pure drinking water and alkaline ionized water

Table of compare pure drinking water and alkaline ionized water

Characteristic Pure water Alkaline ionized water
pH pH = 8.5 - 9.0 - 9.5
Helps neutralize excess acid in the body, which is the cause of many diseases such as acid reflux, bloating, indigestion, and even cancer.
pH = 7.0 (neutral water)
Does not contain acid or alkaline, thus ensuring safety for the body when used. Filtered water helps purify the body, remove toxins and provide water for cells to function effectively.
Water molecule size 2.5 nanometers
Penetrates into the body longer than alkaline ionized water.
0.5 nanometers
Allows the ability to penetrate cells faster, replenishing essential nutrients.
Natural trace minerals Contains no natural trace minerals
SAPUWA's purified water after ion filtration technology still retains some beneficial minerals.
Contains natural micro-minerals (Ca+, Na+, Mg+...) to help supplement necessary micro-minerals for the body's metabolism.
