Quality and function
Often confirmed


For two decades, ME & Friends AG has stood for conscious engagement with the issues of people, health and nature.

The company founder, Michael Ertl, is aware of the special responsibility and places product quality at the centre of the company philosophy. We take comments from our customers personally and treat them with respect.

The reason for these regular product tests is not to collect certificates, but to critically scrutinise our products on an ongoing basis and have them tested.

In addition to product quality, we are increasingly focusing on ethical principles and the preservation of our environment. With the establishment of responsible supply chains, CO2 levies in the transport of goods and new environmentally friendly manufacturing processes, we are significantly reducing our carbon footprint.
