Rethinking clean air

Cler is a Swedish company delivering reliable clean air for environments where it matters most.

Why Cler exists

Clean air should be consistent. Cler was built to deliver continuous air purification without performance dropping over time. Disposable filters create 30 million tons of waste annually. Cler eliminates that cycle entirely.

About Cler's technology

Traditional high-grade filters demand constant replacement and consume large amounts of energy. Less than 10% of buildings worldwide meet WHO air quality guidelines.

Cler was built to change that. Centrifugal separation delivers continuous PM0.5 filtration without consumables or manual work. Clean air becomes accessible, not just for premium installations.
