Brief overview of remineralization filters and their purpose
Remineralization filters are a popular solution mainly for those who want to improve the quality of drinking water after the reverse osmosis system. But the question is, do remineralization filters work for real?
The purpose of remineralization filters is adding essential minerals like calcium and magnesium back into the water, which are often removed during the reverse osmosis filtration process.

What are Remineralization Filters?
The Definition of Remineralization Filters
Remineralization filters are devices used in water purification systems that reintroduce minerals, such as calcium and magnesium, back into the water.
These filters are particularly useful for systems that use reverse osmosis or distillation to purify water since these methods remove all minerals from the water.
Remineralization filters come in various forms, including those that use coral calcium or Himalayan salt.
How they work
They work by passing the water through a filter containing natural mineral stones or cartridges with minerals like calcium carbonate, magnesium oxide.
As the water after the reverse osmosis has an acidic pH value, the minerals dissolve in the water, increasing its mineral content and raising the pH to a more neutral level.
Benefits of Remineralization Filters
- Improved taste of water
- Addition of essential minerals like calcium and magnesium
- Neutralizing acidity of RO water
Do Remineralization Filters Work?
Evidence supporting the effectiveness of remineralization filters
The role of pH in remineralization filter effectiveness
In order to a remineralizing filter work, it needs acidic pH of inlet water. This is why they work best on reverse osmosis water, and this is where they are the most important.
Stage 1 – water flows through one – micron filter pads which remove suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter.
Stages 2 and 3 – water travels through a special blend of natural calcium carbonate media which will alkalize/ionize and remineralize the water and raise the pH level of your water.
Stages 4 and 5 – Water travels through special blend of natural Infra-Red and mineral balls.
Stage 6 – water again flows through one – micron filter pads which remove suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter.
Where remineralization filters may not work as expected
On higher capacity reverse osmosis water purification systems, the water can flow too fast through the remineralization cartridge. As the contact time is short, the water can not dissolve the required quantity of minerals.
So, it is very important to take care about the contact time, and provide the adequate capacity remeneralizing filter cartridge.
Also, waters with a pH value close to 7 take more contact time than lower pH value water.
How to Ensure Remineralization Filters Work
As the minerals are being dissolved by passing water, the remineralization filters can’t work forever. It is important that they are replaced during regular maintenance or service of your RO system.
The recommendation is that they are replaced at least during every second regular service (6 – 12 months).
Periodical measuring of TDS (total dissolved solids) value is very important to keep track of your RO unit and a remineralization filter.
When you notice that the TDS value of purified water is lowering over time, it is time to change the remineralizer.
This handy, portable meter is used by water quality professionals to test the effectiveness of your reverse osmosis filtration system.
Portable and handy TDS meter is a great water treatment test and effectiveness test of reverse osmosis house filtration systems. Advanced technology, easy use.

Frequently Asked Questions
Q: What is the remineralization process?
A: The remineralization process is adding back salts and minerals to purified water.
Q: Can remineralization filters remove harmful contaminants?
A: No, remineralization cartridges are not designed to purify water.
Q: How often should remineralization filters be replaced?
A: 6 to 12 month should be the usual time for replacement
Q: What are the signs that a remineralization filter is not working?
A: Lower than usual TDS value of your RO purified water should be a sign that it is time for replacement.
Remineralization filters are devices used to reintroduce minerals into purified water, particularly in systems that use reverse osmosis or distillation.
These filters come in various forms, including those that use coral calcium or Himalayan salt. The need for remineralization can be determined by the pH level of the water.
Final thoughts on do remineralization filters work?
So do remineralization filters work? The answer is yes.
If their technical requirement are met, yes they do work, and can further improve the quality of your purified drinking water.
