The historical page presents residual odours after renovation as a sign of excessive VOCs and promotes CT catalyst treatment as a solution.

It quotes a TVB news report asserting that Hong Kong has the highest average indoor formaldehyde level in Asia.

New furniture and renovation materials may release volatile organic compounds. The source lists formaldehyde, benzene, toluene, xylene, tetrachloroethylene, styrene, dioxane, chloroform and ethylbenzene.

It describes formaldehyde as a colourless, pungent, volatile toxic gas released over 3–15 years from products such as paint, glue, wooden furniture, wallpaper and leather, and attributes toxic, carcinogenic and developmental effects to WHO findings. These statements are preserved as source claims.

The source promotes CT catalyst as a patented Japanese purification technology that decomposes formaldehyde odours even in darkness, and claims it is certified, effective, non-toxic, non-irritating, environmentally friendly and free of secondary pollution.

The described service measures VOC concentration, then uses an AIR MISTY spray gun and nano-processed CT catalyst on doors, air conditioners, ceilings, walls, curtains, furniture, kitchen cabinets, bathrooms and internal/external cabinet surfaces.

The source attributes the invention to Dr. Shoji Ichimura in Japan and lists patent 3514702, dated 23 January 2004.
