With the VWI Cirqulair, and the VWI Cirqulair Silent version, clean ambient air is available for everyone.

The technology behind the Cirqulair is derived from 25 years of research and study. In those years of research, we unveiled the behavior and properties of fine and ultrafine dust. This led to the development of an air cleaning unit for indoor situations, named the Cirqulair. The Cirqulair will improve the ambient air we breathe like no other air cleaning system has ever done.  

Every air cleaning device is meant to improve the quality of the air we breathe. The Cirqulair is not developed to realize some improvement, but to deliver maximum improvement; clean air in its purest form.

Clean Air in One Take!

Maximum improvement in one take is more economical and more environmental friendly in terms of carbon footprint by energy consumption. While the Cirqulair cleans air in just one take, every other device will need at least 20 runs to achieve the same result as one Cirqulair unit.


The removal of the filter section only needs to be done every 42 months. When you compare this with other suppliers where a change is needed from 1 month to a maximum of maybe 6 months.

5 different groups of dust

  1. Group 1 – Big dust, everything bigger than 10 micrometers
  2. Group 2 – Fine dust smaller than 10 micrometers but bigger than 2,5 micrometers
  3. Group 3 – MPPS dust smaller than 2,5 micrometers but bigger than 0,1 micrometer
  4. Group 4 – Ultrafine dust smaller than 0,1 micrometer (100 nanometer) but bigger than 1 nanometer
  5. Group 5 – Picodust everything smaller than 1 nanometer.

What is the Cirqulair efficiency?

  • Group 1: 100%
  • Group 2: 100%
  • Group 3: 100%
  • Group 4: 99.99999997%
  • Group 5: above 99%

Group 5 mostly contains gasses like VOC’s, PAK’s, NOx, SOx, NH3, H2S etcetera.

A Cirqulair unit can be made for any kind of ambient air pollution!
