Our filters are able to filter the tap water in 99.5% of Spain where the mains water has passed the local authorities’ potability tests. In the case of wells or private water tanks TAPP Water cannot guarantee water portability.

Our activated carbon filtering technology removes over 100 water contaminants, among them chlorine (the main cause of tap water’s unpleasant taste), microplastics, lead, nitrates and nitrites (only measurable using special lab equipment).

According to hundreds of studies worldwide, tap water that meets the potability standards set by the World Health Organization (USA and European Union) is just as healthy as bottled water. Furthermore, tap water costs less than 0.16 cents per litre according to Spanish consumer organisation OCU. That contrasts with bottled water, which costs 20 cents per litre or more, making it 200 times expensive (or even more, depending on the brand).

Unlike bottled water, taps offer a limitless water supply that’s always available when you need it. And there’s no need to go out and buy it, carry home the heavy bottles and later dispose of the plastic waste.

In blind taste tests, 9 out of 10 people could not taste the difference between filtered water and bottled water.

And with regard to the environment, plastic waste is destroying our oceans and ecosystem. Less than 10% of the plastic produced worldwide is recycled, the rest ends up dumped in landfill or the natural environment.

For these 5 reasons, we invite you to stop drinking bottled water and start drinking filtered tap water with TAPP 2.
