Indoor Air Quality Check

Indoor Air Quality Check

Indoor Air Quality Check is a home visit service that combines the Mould Test with the Carbon Dioxide (CO2) and Formaldehyde Check. The former helps to identify excessive fungal growth and active water damage in the surroundings while the latter assesses levels of carbon dioxide and formaldehyde, one of the most common volatile organic compounds (VOCs).


High humidity and water damage can induce mould growth, which in turn can lead to respiratory, skin and sleep disorders, or cause fatigue, dizziness, depression, tremors and headaches. We will use the Mycometer-Air test to assess an environment’s mouldiness, and recommend ways to manage humidity and control mould growth.


VOCs such as formaldehyde are widely used in furniture, paints, cleaning solvents, fragrances, and moth balls. They can be toxic even at low concentrations, irritating the eyes, triggering headaches and asthmatic symptoms, especially when ventilation is poor and CO2 concentration is high. We will use professional instruments to measure formaldehyde and CO2 levels, and will recommend integrated solutions to improve ventilation and lower concentration of CO2 and indoor pollutants, while also controlling humidity to prevent mould growth.


Remote Site Charge

We will add charges for extra transport costs such as ferry tickets and taxi fares on South Lantau Island based on actual receipts. There will be no extra transport charge for Kowloon, Hong Kong Island and the New Territories (except for outlying islands).
