Tips To Get Your Own Alkaline Water Filters To Remineralized Filtered Water

Alkaline water is defined as water with a pH higher than 7.0. Alkalinity is the measure of the capability of water to neutralize acids or resist changes in pH that would make the water acidic (pH below 7.0). It primarily results from the presence of limestone or calcium minerals in the source water. Lower alkalinity water is conducive to corrosion of the pipe materials distributing the water to the customers. Lower alkalinity water also indicates the absence of essential minerals such as calcium and magnesium that help in maintaining healthy bones and prevent many other diseases such as kidney stones and cardiovascular issues. Desalination of seawater is commonly practiced in the UAE for drinking water treatment purposes. One of the most commonly known disadvantages of desalination and reverse osmosis processes, in particular, is the reduction in pH and alkalinity or increase in acidity of the water.

It also results in the reduction or elimination of essential minerals such as calcium, magnesium, etc. from the water. Filter remineralization is a good post-treatment solution to provide pH with all nutrients. However, the demand for alkaline water, in particular, has gained significant impetus over the last few years. Although no direct scientific evidence has been established demonstrating the health benefits of drinking alkaline water, it has gained popularity owing to its good aftertaste as compared to regular water and its contribution to treating symptoms related to acid reflux. This article aims to provide a comprehensive overview of the different treatment types of alkaline filters that are available in the market and also provide guidance on how to select the product best suited for the customers’ needs.


Alkaline filters provide convenient and portable solution for demineralized water coming either from desalination plant or reverse osmosis process. There are several options available in the market today for alkaline filters.

1. Alkaline Pitcher Filters

  • Provision of clean and high pH (between 8.0 and 10.0) water instantaneously with ease of storage in refrigerator, kitchen counter, dinner table, etc. due to compact size
  • Pitchers are available in different materials such as stainless steel, BPA-free plastic
  • Pitchers come with replacement filter cartridges that can be changed every 6 month or less depending upon usage and water quality
  • Natural and cost-effective means of remineralized water


2. Under-Sink Alkaline Filters

  • Higher flow rates as compared to pitcher filters to provide higher volume of water that can be used for cooking and drinking purposes
  • Not portable like pitcher filters but compact enough to fit under sinks/counters
  • No need to replace filter cartridges; most models come with self-cleansing process



  1. pH range – should be typically between 8.0 – 10.0
  2. Types of minerals added (calcium, magnesium, and potassium)
  3. NSF certification
  4. Shelf life of filter cartridges and filter housing
  5. Filter cost and warranty

Alkaline filters can help restore the nutrients lost during desalination or reverse osmosis processes. As discussed above, there are a variety of options available to get alkaline water in the form of pitchers and under-the-sink filters. The water experts and consultants at Saniwater can give recommendation to their customers on what product is suitable for their needs. The technicians can help with installation of under-the- sink filters. Saniwater is dedicated to provide best solutions to meet the drinking water requirements of their customers.
