DIRO - A filter system that makes it possible to wash and clean completely without chemicals

The DIRO system offers a new sustainable, environmentally friendly, healthy and allergy-free way of doing surface cleaning and laundry. The filter system is installed between incoming cold water and one or several laundry machines. A tap is also installed allowing the user to tap up DIRO water on spray bottles and use it for all daily cleaning. The DIRO system can also be installed with a recirculation system for greywater from the laundry machines. By recycling the water, users can save up to 75% of the water used in laundry and at the same time remove all microplastics from the greywater. The DIRO system comes in three different sizes depending on water usage but can also be made bespoke for larger installations in laundry facilities or cleaning centrals.
