Introduction
You might have heard it before: RO water is super clean. But then comes the big question – is it safe to drink long term? Especially for households in Kenya where water quality varies wildly, this is more than just a curiosity; it’s a health concern.
Let’s clear the air (and the water!) on whether Reverse Osmosis (RO) water is friend or foe over the long haul.
What is RO Water?
RO stands for Reverse Osmosis, a filtration method that forces water through a semi-permeable membrane to remove contaminants. This includes heavy metals, salts, microorganisms, and impurities.
How Does RO Filtration Work?
Imagine squeezing dirty water through an extremely fine net. That’s what the RO membrane does. It blocks anything larger than water molecules, leaving almost pure H2O on the other side.
Why Do People Choose RO Water?
It removes 95-99% of total dissolved solids (TDS)
Filters harmful bacteria and viruses
Improves taste and odor
Great for borehole or salty water
Especially in Kenyan towns where borehole water can contain iron, fluoride, or salts, RO systems are becoming a household staple.
The Composition of RO Water
RO water is nearly pure, but therein lies the issue: it may lack essential minerals like calcium, magnesium, and potassium, which are important for bodily functions.
Pros of Drinking RO Water Long-Term
Safe from contaminants: Removes chlorine, arsenic, lead, nitrates, etc.
Better taste: No metallic or chemical aftertaste
Helpful for sensitive groups: Safe for infants and those with compromised immunity
Cons of Drinking RO Water Long-Term
Mineral deficiency: RO strips away even the good minerals
Acidic pH: RO water tends to be slightly acidic (pH ~6.5)
Flat taste: Many people describe it as bland
Increased plastic usage: Due to bottled RO water when filters fail
Is RO Water Really Devoid of Minerals?
Yes. RO removes most minerals. This isn’t necessarily bad – many foods and diets supply those nutrients. However, relying only on RO water without dietary balance can lead to deficiencies over time.
Can Demineralized Water Be Harmful?
Some studies suggest drinking demineralized water may:
Affect electrolyte balance
Lead to low calcium/magnesium intake
Increase diuresis (you pee more, losing sodium and potassium)
But it’s worth noting: these risks are minor if your diet is rich in vegetables, fruits, and mineral sources.
What Does WHO Say About RO Water?
The World Health Organization (WHO) notes that low mineral water may not be ideal for long-term use unless re-mineralized. Minerals in water support hydration and bone health.
How to Re-Mineralize RO Water
Simple tricks:
Add a remineralization filter (available with most modern RO systems)
Use Himalayan salt or mineral drops
Store in clay pots or mineral pots to boost trace minerals
Protech Water and Solar Equipments Company in Kenya offers complete RO systems with remineralization cartridges, solving this concern effortlessly.
Role of TDS in Healthy Drinking Water
TDS (Total Dissolved Solids) is a measure of minerals and salts in water. RO brings this down drastically.
Ideal TDS range for drinking: 150 – 300 ppm
RO water often has TDS below 50 ppm – too low!
Alternatives to RO Systems
UV Purifiers: Good for pathogen removal, but don’t handle salts
UF Filters: Keep minerals but miss chemicals
Activated Carbon Filters: Great for chlorine, but weak against heavy metals
If your water isn’t high in TDS or heavy metals, you might not need RO at all.
Who Should Avoid Drinking Only RO Water?
People with mineral deficiencies
Athletes or active individuals who lose minerals through sweat
Children and elderly needing more calcium/magnesium
Balance is key. Pair RO water with a healthy diet, or simply add a mineral booster.
Best Practices for Using RO Water Systems
Change filters regularly (every 6-12 months)
Add remineralization unit
Monitor TDS with a digital meter
Ensure professional installation
And of course, buy from reputable providers.

FAQs
1. Can I drink RO water every day?
Yes, as long as you ensure mineral intake through food or remineralization.
2. Does RO water weaken bones?
Not directly. But if it’s your only water source without minerals, and your diet lacks calcium, it could contribute over time.
3. Is RO water better than bottled water?
Often yes! It’s cleaner, cheaper in the long run, and reduces plastic waste.
4. What is the ideal pH of drinking water?
Between 6.5 and 8.5. RO water is slightly acidic but not harmful.
