About CLER
At CLER, we're redefining clean air. CLER is a deep-tech start-up that is revolutionising global air purification. Our cutting-edge, filter-free purification technology delivers ultra-clean air while requiring no maintenance, consuming less energy, and delivering a much more sustainable solution.
Why this matters:
99% of the world’s population breathes air that fails to meet WHO guidelines, causing more than seven million deaths each year.
Indoor air quality is often 2–5x worse than outdoor air, even though we spend 90% of our lives indoors.
CLER's technology is backed by smart Swedish engineering and rigorous innovation. We believe in creating effortless, reliable air quality solutions that work for everyone, without compromise.
We aim to become the new global standard in air filtration. Our ambition is to redefine how the world cleans its air - by cutting waste, reducing CO₂ emissions and protecting public health.
