The system drains surface impurities through the overflow and through a bottom nozzle, water is then filtered at 1 micron, chlorine-free (or with a minimum rate if the regulations require it) and unparalleled durability.

The Cocoon has been designed to meet two needs: ecology and sustainability.
The combination of design and revolutionary water treatment technology has resulted in the creation of this beautiful product, easy to integrate into the environment and offering crystal clear and odorless water to its happy users!
Water savings
No more water changes thanks to the UBO Nature treatment system.
The water and spa surfaces are treated to prevent biofilm formation, which, once developed, would require a complete drainage, deep cleaning, or the use of chemical products.
Thanks to its innovative design, UBO Nature significantly reduces water consumption during backwashing.
Energy savings
To further our commitment to protecting the planet, the integrated heat pump eliminates the need for constant reliance on costly electric heating (which is only used as a backup to boost the heat pump when necessary).
By incorporating a multi-speed management module for the filtration pump (optional), UBO Nature optimizes treatment through UV technology and advanced oxygenation, reducing electricity consumption by a factor of 3 to 4 compared to competing systems.
Respect the environment
No more constant chemical additives!
UBO Nature eliminates the need for chlorine and other chemicals to ensure bacteriological water treatment.
The water remains crystal clear, free of biofilm on the surfaces, and most importantly, without the unpleasant odors associated with chlorine.
Eco-design has been at the heart of our approach, following a methodical process to minimize the environmental impact of this type of equipment.
