Alkaline Water Purifier: Benefits, Myths & Who Should Buy One

Alkaline water purifiers have become one of the most searched home appliances in Indian cities. But what do they actually do — and do you need one? Here's a balanced guide.

What is an alkaline water purifier?

It's typically an RO purifier with an extra alkaline / mineral cartridge. RO removes almost all dissolved solids — including healthy minerals — leaving slightly acidic water. The alkaline stage adds back calcium, magnesium and potassium and raises pH to about 8.5–9.5.

Real, practical benefits

• Restores minerals removed by RO.
• Better taste — most people find it smoother than flat RO water.
• Encourages hydration — when water tastes good, people drink more.
• Less acidic than plain RO output.

Myths to be careful about

• “It cures diseases.” There's no reliable evidence that alkaline water treats illnesses. Be wary of exaggerated claims.
• “Higher pH is always better.” Very high pH water isn't recommended for daily drinking. 8.5–9.5 is the sensible range.
• “It replaces purification.” The alkaline stage only works after proper RO/UV purification.

Who should consider one?

• Homes already using RO with high-TDS borewell water
• Fitness enthusiasts, gyms and wellness centres
• Clinics, salons and offices wanting premium drinking water
• Anyone who dislikes the flat taste of RO water

Upgrade instead of replacing

If your existing RO is in good condition, an alkaline add-on filter can be fitted for a fraction of the cost of a new purifier.
