Bottled water is worse than tap water in terms of health as it contains microplastics according to multiple studies.

It’s small, affordable, environmentally friendly, easy to use and probably one of the greatest water filters. TAPP 2 filters over 100 common contaminants including e.g. chlorine, pesticides, herbicide, lead, most pharmaceuticals and microplastics.
The water flows through activated carbon which is one of the most absorbent material known to man, and it is uniquely efficient because of millions of tiny pores that it can absorb. The highly compressed carbon block used in TAPP 2 filters particles as small as 1 micron but leaves most of the healthy minerals.
The cartridges are made of organic coconut shell and recyclable plastic and need to be replaced approximately every 3 months. Once used they can be separated and disposed with organic and plastic waste.
TAPP offers two versions of the filter including a smart connected version that monitors filter status, savings, eliminated bottles, CO2 reduction and a standard version.
Currently as little as €79-89 (based on campaigns) for the first year and then €59 per year.
What are you waiting for? Get your TAPP filter and start drinking healthy, affordable and sustainable water now.
