How to Explain Water pH Simply (and Help Customers Understand Why It Really Matters)
Water and pH: The Right Answers to Sell Better
If you rent water dispensers or purifiers to end customers, you’ve probably heard questions like:
“What’s the ideal pH of drinking water for health?”
“Is alkaline water better than neutral water?”
I’m Fabio Tesi from OnnWater, and in this article I’ll give you the best, most professional — yet simple — answers to share with your customers so you can communicate clearly, build trust, and sell more effectively.
Why It’s Essential to Answer pH Questions Correctly
The internet is full of confusing content about “water and pH.”
Videos, articles, social posts, and ads often spread misinformation and half-truths that create false myths among consumers.
If your customers are “educated” by these sources, they might hesitate — or even give up — on renting a water purifier out of fear or confusion.
That’s where your professional competence comes in: knowing how to explain the truth clearly makes you the trusted expert they rely on.
Does Water pH Really Affect Health?
Simple answer for your customer: No, the pH of drinking water (usually between 6 and 8) has no harmful effects on the human body.
Once ingested, water enters the stomach — an extremely acidic environment (pH 1.3–2) — which neutralizes any variation in the pH of the water.
A practical example: Drinks like wine, lemonade, or sparkling water have a pH between 3 and 4 — far more acidic than tap water — yet people consume them every day without any problem.
What to Say About Home pH Test Kits
Many customers use color-based test strips and assume the result shows how “healthy” the water is. Explain that:
-
The color result is not a reliable parameter.
-
Tap and bottled water are already monitored and certified for safety.
-
Even breathing into the glass can change the pH reading because carbon dioxide alters the result.
What Actually Matters in Water Quality
Redirect your customer’s attention to what really counts:
-
Chemical contaminants
-
Heavy metals
-
Bacteria and viruses
-
PFAS
-
Chlorine and microplastics
These are the real factors to evaluate — not pH.
The ideal solution is a dispenser equipped with advanced filtration such as reverse osmosis, ultrafiltration, or microfiltration.
Bottled Water vs Tap Water: Which Is Safer?
Make it clear that tap water is far more controlled than many bottled waters on the market.
And by filtering it with the right system, you can elevate its quality and safety even further — without spending money on packaged water.
Debunk Myths Before You Talk About Product Benefits
Don’t start by listing technical features, materials, or maintenance details.
First, clear your customer’s mind of false beliefs so they’ll be open and receptive to the real benefits of your solution.
Once the myths are gone, your product’s value will speak for itself.
