Ownwell® method

The Ownwell® cleaning method, which supports environmental friendliness and wellbeing, is a responsible choice for implementing cleanliness. The method is based on a Finnish innovation for which there is a patent pending. In the method, mains water is purified and optimised to be suitable for cleaning purposes.

Safe cleaning capsules are added to the purified water. The capsules contain probiotics, which break down debris with the help of enzymes and reduce disease-causing bacteria. One of the significant strengths of the method is diversity; it is suitable for various cleaning methods, including the washing of cleaning textiles.
