Dispenser vs Purifier: Side by Side
| Water dispenser | Water purifier (UF/RO) | |
|---|---|---|
| What it does | Cools or heats bottled water | Removes germs, dirt (UF) or salt and fluoride too (RO) |
| Water source | Bought 20 L bottles | Your tap, tank or borehole |
| Running cost | Every refill | Filters and membrane changes |
| Needs plumbing | No | Yes (under the sink) |
| Hot water | Most models | No (unless combined) |
Cost Comparison (Worked Example)
Example only: a family using 40 L of drinking water a week. Buying two 20 L refills a week at KSh 150–300 each costs roughly KSh 1,200–2,400 a month. A purifier costs more upfront, plus filter changes, but the water itself costs only what you already pay for tap water. Use the cost per litre calculator with your own numbers.

Which type? RO vs UF. Hard water too? Do I need a softener?
Can You Use Both?
Yes. Many offices fill a bottom-loading or bottle dispenser with purified water from their own RO system, getting cold water without buying bottles. Keep bottles clean: how to sanitise 20 L bottles.
Do You Sell Water Dispensers?
We focus on the purification side (purifiers, UV, refill stations). If you need cold water for many people, we can size an RO system to feed your dispensers or a cooler.
