This test aims to determine the level of a list of common IAQ parameters in indoors. For example, PM2.5, carbon dioxide (CO2), carbon monoxide (CO), nitrogen dioxide (NO2), formaldehyde (HCHO) and volatile organic compounds (TVOC) etc. The test can also determine the filtration performance of a vacuum cleaner or air-purifier. After the service, you will receive a test report and our recommendations (related services and products) based on the results.
