Housing corporation Woonstede came in contact with Euromate with the request to provide advice and solutions to address these persistent symptoms. Firstly Woonstede and Euromate hired the organization RPS Analysis BV to carry out an objective measurement of the air quality to determine the direct effects of the air cleaner.
Regarding MAC values and experience figures for particulates, solid toner materials, ozone and microorganisms RPS appointed no problem fixed values. This related both to the baseline without air cleaner as well as to the post-test with air cleaner. However, a perception survey a month later revealed that employees noticed clear improvements in the air quality and physical symptoms.
