Air filter systems with know-how

Air filter systems are used in all situations where harmful substances need to be reliably removed from indoor air. Whether in the medical field, business premises, hotels, restaurants or in private homes – the use of indoor air filters makes a valuable contribution to significantly reducing the risk of infection from coronaviruses (SARS-CoV-2 / COVID-19), influenza viruses and other health-damaging airborne particles.

Our portable and fixed indoor air filters remove over 99.9% of all viruses, bacteria, pollens, gases, odours, aerosols and other harmful substances from indoor air. Even extremely fine particles are safely and reliably removed from the air.

Our indoor air filters are manufactured by the ETS Products Group®. This new high-tech generation of air cleaners is designed and developed in Germany. The superb effectiveness of the complex filter technology was tested and proven by two independent institutes.
