Wet dust cannot fly. Fact! And dust or dirt, combined with water, does not pollute the air we breathe. It’s as simple as that. The HYLA cleaning system is based on this premise –the healthiest in the world. The brochure design is pared back to the fundamental: beige for dust, blue for water and water-like drops. Simple and straightforward. And the slogan says it all – wet dust doesn’t fly!
