VOC removal service

VOC removal service is designed to remove harmful formaldehyde after decoration. VOC does not produce immediate danger, nor it is fatal. Nevertheless, long term inhalation affects health of human body, especially for infants, pregnant women and elderlies.

VOC can cause respiratory and nervous system diseases such as cough, sore throat, chest tightness, dizziness, nausea, weakness of limbs, dyspnea, lethargy and so on. It can also cause severe cancers such as nasal cancer, throat cancer, skin cancer and leukemia. Therefore, excessive VOC is very harmful to human health.

Smart Home uses Japanese CT and air catalyst decomposition method to remove VOC: catalyst with oxygen and moisture in the air produces negative ions and hydroxyl radicals. This oxidizes and decomposes various organic and inorganic pollutants, and they eventually degrade into carbon dioxide, water and corresponding acids, which are harmless substances. So that while achieving the decomposition of pollutants, we purify the air as well. Service is suitable for all households and highly recommend for schools, kindergartens, hospitals and offices. The procedure is absolutely harmless for everyone, including kids and pets.


It is suitable for any unit, household or Hotels, especially for those that were recently renovated.

Many new decoration units and new furniture are newly painted, paint and adhesives will release a large amount of VOC , benzene, toluene, xylene and other volatile organic compounds (also known as VOC). Some wooden wardrobes with high VOC content takes more than 18 months or more to evaporate.

Office and shops

In order to provide a healthy working environment for staffs and customers, it is necessary to remove harmful formaldehyde, especially for infants, pregnant women and elderlies.

VOC Process

  1. Customers must clean all the furniture in the house thoroughly to achieve the best result. Customers can also use the company's deep cleaning service instead, HK$150 discount will be applied.
  2. Smart Home uses professional VOC measurement instrument (American brand RAE/miniRAE Life). The United States RAE patent TVOC can measure the formaldehyde and other VOC gas (including harmful VOC gas) accurately. The Environmental Protection Agency of Hong Kong sets the target value of total volatile organic compounds (TVOC) for indoor air quality at 200 and 600 mu g/m3, and that is 0.087 ppm and 0.261 ppm (excellent accuracy).
  3. For VOC removal, our technician will inspect and record VOC index at each location for comparison.
  4. We use the Japanese special spray gun, the catalyst particles will be evenly distributed inside and outside the new house. By spraying back and forth, we can ensure the catalyst is carefully distributed.
  5. Once the VOC removal process is completed, we will inspect the VOC level and re-test each location. Customers can compare the changes of index before and after our VOC removal service. Customers will be asked to sign on a report, which both parties will keep a copy of, and we will make sure all locations are within the safety standard.
  6. Then the air purification /VOC removal service is completed.
  7. Smart Home advices customers to open the windows and turn on the fans as much as possible after our service. This ensures air circulation, speeds up air purification and plays a powerful role in decomposition of compounds.
