Indoor Air Quality Test

Our indoor air quality (IAQ) test is suitable for general household and institutional clients. The test includes the most common air problems such as respirable suspended particulates, volatile organic compounds, formaldehyde, nitrogen dioxide, ozone and carbon dioxide. By conducting our in-depth air test, it enables us to analyze the quality of indoor air and the sources of pollution. Then we will address needed solutions to deal with the indoor air pollution. 

Test Content Overview

We use multiple state-of-art measuring instruments to measure accurate reading for each item. We provide users with on-site measurement reports and compare with the air quality standard provided by World Health Organization and the Hong Kong Environmental Protection Department for reference.
