Why investing in an air purifier?

Wherever people come together, the risk of transmitting pathogens in the indoor air is increased. This results in increased sick leave and thus high costs for companies. There are a number of known diseases that can be easily transmitted through the air, such as influenza, SARS, Covid-19 or measles, chicken pox and whooping cough. In addition, more than 150 million Europeans now suffer from chronic allergic diseases.

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.
