What to look for in a water purifier? When it comes to drinking water, we all want the purest and healthiest possible. So many filters, so many purifiers, and so many bottled water options, and they’re all competing for your drinkable dollar. The reverse osmosis (RO) system is one of the most widely used water purification techniques as it effectively filters impurities and leaves you with clean, clear water. But is RO water healthy? And if it is deficient in minerals, how do you remineralize it to optimize your health?
In this post, we’ll dive into the science of reverse osmosis, how minerals matter, and the best systems for healthier water at home.
How Does a Reverse Osmosis Water Filtration System Work?
The reverse osmosis water filter is a kind of water purification system in which water is pushed through a semipermeable membrane under pressure. This membrane removes impurities such as heavy metals, fluoride, chlorine, lead, arsenic, bacteria, and viruses.
Here is how it works, in simplified terms:
-
Pre-filters eliminate sediment, chlorine, and other big particles.
-
After that, the contaminants are filtered through an RO membrane.
-
Follow one set of filters to improve the flavor and eliminate any leftover odors or substances.
This clean water can be stored or sent straight to your faucet.
The result? Water that is 95–99% pure. However, during this intense filtration process, essential minerals like calcium, magnesium, and potassium are also removed.
Why Do You Need Essential Minerals in Drinking Water?
The human body requires essential minerals in small amounts for strong bones, nerves, muscles, and overall cellular function.
Common minerals found in natural drinking water include:
-
Calcium – Strong bones and teeth.
-
Magnesium — Aids muscle and nerve function.
-
Potassium – vital for the health of the heart and muscles.
-
Sodium – Maintains fluid balance.
Drinking demineralized water long-term may lead to a mineral imbalance in the body, increase the risk of acid buildup, and negatively affect hydration. That’s why remineralizing reverse osmosis water is a smart move.
How to Remineralize Reverse Osmosis Water?
Remineralization is the process of adding healthy minerals back into RO water. Here are the most effective and easy methods to do that at home:
Add a Remineralization Filter
The easiest method at home would be to add a remineralization filter to your RO system. This post-filter introduces calcium, magnesium, and other healthy minerals as the water moves through it. This feature can be found in most solid RO systems.
Use Mineral Drops
Alternatively, you can mix in liquid mineral drops with your filtered water. You can get these drops online or in health food stores, and they also allow you to monitor the amount of mineral content you prefer.
Add Himalayan Pink Salt
A pinch of Himalayan pink salt in a glass of RO water can help supplement trace minerals. It has more than 80 minerals in it and is a natural and inexpensive remedy. Season lightly so that it’s not too salty.
Use a Mineral Stone Cartridge
Certain filters contain mineral stone cartridges consisting of calcium, iron, and magnesium stones. Techniques like this are long-lasting and hassle-free.
What Are the Benefits of Remineralized RO Water?
Remineralizing your RO water can enhance not just the taste but also your health. Here are some key benefits:
-
Better Taste – RO water may taste bland. Minerals enhance the natural flavor.
-
Improved Hydration – Minerals assist the body in maximizing hydration.
-
Balanced pH – water with too high or too low pH can be harmful; it is important to have a good body pH.
-
Better Body Function – Minerals also help in metabolism, bone health, nerve signaling, and more.
-
Highly remineralized reverse osmosis drinking water gives you the best of both worlds: purity + nutrition.
By drinking remineralized reverse osmosis water, you're getting the best of both worlds—purity and nutrition.
Which RO Water Filters Are Best for Healthier Water?
If you’re ready to make the switch to healthier RO water, choosing the right filter is key. Here are the best options to consider for your home:

Summary
What is the healthiest water to drink? The solution is pure, mineral-laden water. Reverse osmosis systems effectively filter out dangerous contaminants, but they also strip away beneficial minerals. If you want the healthiest water, you should remember to add minerals back into your RO water with a filter, drops, or a natural source of minerals.
No matter if you opt for an under-sink RO system, a countertop reverse osmosis water filter system, or a tankless reverse osmosis system, ensure it has a remineralization stage to enrich your health and hydration. Healthy water should be nourishing, and with a system in place, you can have both.
Drink smart. Drink healthily. Drink mineral-rich RO water. You can trust Glacier Fresh Filter to get the best products to keep your water healthy.
