The purification process lasts between 2 and 6 hours, depending on the amount of sun to which the drum is exposed.

Solvatten provides hot, purified water where it is needed, without burning fuel and without the need for chemicals.

It has a durability of between 7 and 10 years. A single drum meets the needs of a family of 5-6 members.
