So, you know that you need clean, filtered water for cooking, drinking, and other reasons. You’ve researched and assessed your budget but are still confused about the option to settle for.
Should I go for reverse osmosis or alkaline water? What is the best kind of filtered water for my family? You wonder.
It’s totally overwhelming since both have their pros and cons. Making a decision has never been this difficult.
But don’t worry. We are here to make things less complicated for you. In this post, we give a quick breakdown of alkaline water and reverse osmosis to help you choose the right option for your home.

Alkaline Water vs. Reverse Osmosis: Key Points
|Feature||Alkaline Water||Reverse Osmosis|
|Size||Space-saving(small alkaline filters and jugs)||Space consuming( large RO systems)|
|Power||It doesn’t require electricity||Requires electricity|
|Water wastage||Doesn’t waste water||It wastes a lot of water|
|Minerals||Adds mineral content to your drinking water.||Removes essential minerals from water.|
|Effect on pH||Raises the pH level of water||Makes water acidic|
|Health considerations||More healthy||Healthy|
What is Alkaline Water?
Alkaline water is, in simple terms, water with higher potential hydrogen than plain drinking water. It has a pH of 8 to 9.5, higher than that of plain drinking water.
A solution with a pH of 1 is considered extremely acidic, and one with a pH of 14 is extremely alkaline. Some researchers argue that alkaline water can help neutralize the acid in the body thanks to its high pH.
Alkaline water boasts several health benefits, including cancer prevention, slowing aging, boosting immunity, and reducing acid reflux.
What is Reverse Osmosis?
Reverse osmosis is a water filtration method that eliminates water contaminants by constraining them through a semipermeable membrane under high pressure. The pollutants are sifted and removed from your water using this strategy, leaving your water spotless clean.
Reverse osmosis produces unadulterated drinking water perfect for drinking and cooking. The strategy kills contaminants in the water down to a millionth micron.
Some of the contaminants removed from water during reverse osmosis include sediment, volatile organic compounds, chlorine, pesticides, chloramines, fluoride, and heavy metals, among others.
Although reverse osmosis is highly efficient at removing contaminants from water, it also eliminates minerals like calcium and magnesium, which are essential for human health.

Differences between Alkaline Water and Reverse Osmosis
Reverse osmosis uses power to produce the pressure required to eliminate contaminants from the water and cleanse it.
Alkaline water production doesn’t require any power.
Reverse osmosis systems come with a high upfront price. This, along with the cost of electricity to purify the water, makes the method quite expensive.
You will also have to change filters regularly for optimal performance once or twice a year, adding to the expenses.
Alkaline water jugs are affordable and don’t require electricity hence being cost-effective.
Although reverse osmosis removes contaminants down to 0.0001 microns, it also reduces the mineral content of the water. It eliminates essential minerals like magnesium and calcium from the water.
These minerals are essential for your health, which means that you will have to remineralize the RO water, which is time-consuming.
Alkaline water, on the other hand, is rich in mineral content. The water adds beneficial electrolytes to the body and helps to keep you hydrated.
The water also helps with mineral absorption from your diet, providing the much-needed boost if you don’t get enough minerals from your meals. The body absorbs minerals faster from water than from food.
- Effect on pH
Reverse osmosis removes 99.99% of water contaminants. The filtration process leaves you with pure water with a pH of 7.
When exposed to air, the RO water becomes acidic. On the other hand, alkaline water raises the pH of your drinking water.
To work on the pH of RO water and give it solid mineral substance, you must put it through an ionizer. This process is not only time-consuming but also expensive.
Reverse osmosis systems are large and take a lot of space in the kitchen. You need a spacious kitchen if you intend to install one and other large kitchen appliances.
With alkaline water, you don’t have to worry about space. It comes from a little jug that can even fit in your refrigerator.
- Wastage of Water
A lot of water goes into waste during reverse osmosis. The level of waste varies from model to model, with some wasting up to 5 gallons of water for every gallon of pure water produced.
And although some brands claim to produce RO units that waste zero water, they still do. It’s only that the water gets recycled to water plants and clean cars, among other uses.
To produce alkaline water, zero water goes to waste.
- Health Considerations
As aforementioned, RO water is devoid of minerals essential to your health. This makes it less healthy compared to alkaline water.
Alkaline water contains minerals that make it tasty and healthy. It’s not only great for quenching thirst but also excellent at boosting immunity.
Is Alkaline Water Better than Reverse Osmosis?
From the differences discussed above, it’s clear that alkaline water is indeed better than reverse osmosis. It increases the mineral content of water, helps your body to hydrate, doesn’t require electricity, and is quite affordable.
Alkaline water filters and jugs also take very little space, and the water is healthier than RO water.
Does this mean that you should avoid reverse osmosis? Not exactly. The process eliminates almost every contaminant from water to give you the purest form of water.
And if you are worried about the lack of minerals in RO water, you can restore the minerals through remineralization.
Alkaline water raises the pH of your water, unlike reverse osmosis, which makes it slightly acidic. Reverse osmosis also removes minerals from your water, negatively affecting your health.
You also don’t require electricity to produce alkaline water, and alkaline water filtration doesn’t waste water.
Additionally, reverse osmosis might not work for you if you have minimal space in your kitchen since the systems take a lot of space.
