Air Purification Units CWS INTERsens® 250R & 250

Reliable indoor air filtering and safe infection control with the innovative INTERsens® 250R & 250 air purifiers from CWS.

Why air purifiers?

Wherever people come together, the risk of transmitting pathogens in the indoor air is increased. This results in increased sick leave and therefore high costs for companies. There are a number of known diseases that are easily transmitted through the air, such as influenza, SARS, Covid-19 or measles, chicken pox and pertussis. In addition, more than 150 million Europeans now suffer from chronic allergic diseases. CWS offers you a reliable and certified air filtering solution to render viruses and other pathogens harmless immediately.

Best air purifiers for your needs

Today, more than 150 million Europeans suffer from chronic allergic diseases and the current forecast is that half of the entire EU population will be affected by 2025. CWS now offers you a reliable and certified solution for air filtering and to render viruses and other pathogens harmless immediately. CWS INTERsens® is a combined air disinfection and air purification device that can be easily set up as a mobile air filtering device in the CWS INTERsens® 250R version. With the CWS INTERsens® 250 version, we also offer you an air purifier that can be mounted on the wall. Both air purification devices combine gentle UV-C disinfection with simultaneous air purification.

Fighting viruses with air purifiers

CWS INTERsens® 250R & 250 disinfect the room air absolutely reliably with UV-C, without any UV-C light penetrating to the outside. It has been proven that no ozone or other by-products are produced. Viruses (also SARS-CoV-2 ), bacteria and fungi are destroyed immediately - filterless, quiet and odorless.

The targeted use of UV-C for the disinfection of room air does not pose any risk to humans, as it takes place within the CWS INTERsens® 250R & 250. In the UV-C air purifiers, the air is sucked in together with the pathogens it contains and disinfected inside, only to be released afterwards.

The University of Bochum has specifically tested the functionality of the CWS INTERsens® 250R & 250 to destroy the SARS Cov-2 virus and certified its reliability.

Enjoy the good feeling of effective indoor air hygiene.

Frequently Asked Questions

Do you still have questions about CWS air purification devices? Then you might find the right answer to some of them below. If your question does not appear, please do not hesitate to contact us.

How useful is an air purifier?

To create good working and/or learning conditions, a healthy, clean air is important. Poor indoor air quality can lead to health problems such as:

  • Respiratory problems/asthma
  • Irritation of the eyes and skin
  • Allergic reactions 
  • Headaches
  • Concentration difficulty


Ventilating by opening a window seems to be the obvious solution, but this can let in pollen and fine dust. This is why air purifiers are necessary and useful for good air quality. In addition, draughts from open windows can lead to stiff shoulders or a stiff neck. 

Do air purifiers protect from COVID-19?

All air purifiers offered by CWS are effective against bacteria and viruses in the air, including coronaviruses. This helps to prevent contamination through aerosols.

Which air purifier for allergy sufferers?

All air purifiers offered by CWS are effective against pollen and dust particles in the air. This helps to prevent allergic reactions.
