Awareness Towards Better Health is a Key Driver for the Growth of the Market
There are multiple scientific claims that alkaline water helps in digestion, proper and effective water absorption, reducing indigestion, which happens due to the presence of other enzymes and soothing the acid refluxes. People are using water ionizers so that all these said benefits will keep them healthy. Proper hydration and digestion helps in the absorption of all the nutrients available in food, keeping immunity strong and ultimately helping in disease prevention.
There are other benefits of the alkalization of water, one of them being the removal of carbonate from water. When water is ionized in the ionizer, it separates the dissolved CO2 in water. This CO2 is in the form of carbonate with minerals. When carbonate is removed, minerals get into available form in water, improving the water quality for consumption. Such a factor has tremendously surged the target market to new heights.
Additionally, an increase in online sales of these ionizers is helping the market grow. Manufacturers are reaching customers from all over the world, due to improved online marketplaces and distribution chains.

If filtered water is used for the ionization process, it will not have any effect on the water. Due to such limiting factors, the volume of sales of target products is getting hampered.
Another restraint to the market is the re-mineralization of ionized water. The minerals are reduced in ionized water, and to re-mineralize it, external filters are required. These filters are expensive and are not readily available.
Further, ionized water used in excess can potentially cause several health issues. Since water has a modest alkaline pH, excessive consumption may result in nausea and vomiting. Prolonged consumption may also result in mineral deficiencies and other health issues which is in turn hampering the growth of the market.
Certifications and Consumer Preferences Contribute to the Market Expansion
Japan has initiated the trend of using water ionizers. The main reason for the increased use of ionizers in the country is consumer preferences for the said benefits of drinking alkaline water.
