Why this site?
Beste Waterkoeler compares office water coolers on what ends up in the glass: where the water comes from and what is in it, the price per month and per litre, installation, and what happens to the packaging. Every comparison ends with a price per litre, and every environmental figure comes with its comparison basis and its source.
How we work: the articles are written with AI and then reviewed by the editorial team. We rely on public sources, such as suppliers' product pages and price lists, technical sheets, Test-Aankoop and official bodies. Every article and ranking lists those sources with the date we read them. We do not test the machines ourselves, and where a supplier publishes no price, we write "on quote" and estimate nothing.
