Simple to operate
A few pumps get it started. Turn it like a tap, and safe drinking water will flow by itself. It’s really that simple.
Every time you pump it, the filter also flushes away any trapped debris, so no maintenance is needed. Gravity makes it flow, so no effort is required. 


Easy to deploy
Tapp’s simplicity makes deployment very easy. This saves time and money in training and follow-up.


More likely to be consistently used!
Water filters are prone to technical failures, improper use, and (most of all) disuse when people get frustrated with all the steps and effort they require. We designed Tapp to avoid these problems, so you can increase adoption and long-term use, and help more people stay healthy.
