Photocatalyst formaldehyde removal service

Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, nasopharyngeal cancer, colon cancer, brain tumors, nuclear gene mutations, etc. It must be dealt with as soon as possible.

What are formaldehyde and TVOC?

Formaldehyde is a colorless gas with a special pungent odor and the most common indoor air pollution poison. The main source is building materials. TVOC (Total Volatile Organic Compound) is a volatile organic compound. The main sources are combustion products such as fuel, natural gas, smoking, cooking and other smoke, and even construction and decoration materials (such as paint, coating and adhesive), furniture, electrical appliances, and cleaning agents etc.


At present, the WHO has determined that formaldehyde is a carcinogenic and teratogenic substance. When the concentration of formaldehyde and TVOC in the indoor environment is too high, it will cause a variety of allergic reactions and pathological changes in the body. The irritation can cause tearing and abnormal eye sensitivity. In a short period of time, it will cause headache, nausea, vomiting, and weakness of the limbs. In severe cases, it will cause convulsions, coma, memory loss and allergic reactions. Formaldehyde has an irritating effect on the skin and mucous membranes, causing skin itching, congestion, edema, inflammation, ulceration, asthma and other phenomena. In severe cases, it can even lead to hepatitis, pneumonia and kidney damage. Long-term exposure can cause chronic respiratory diseases and damage the liver, kidneys, brain and nervous system. It contains a variety of carcinogens, causing nasopharyngeal cancer, colon cancer, brain tumors, and nuclear gene mutations.

Formaldehyde and TVOC are more harmful to the next generation. Long-term inhalation will:

  • Lead to abnormal sperm in men and infertility in women

  • Pregnant women have severe pregnancy reactions such as vomiting, nausea, and increased incidence of poisoning, anemia and threatened abortion during pregnancy

  • What's more, the growth and development of the fetus is stopped, and the heart and brain are not fully developed, which can lead to fetal malformations and miscarriage.

  • Long-term inhalation of formaldehyde in infants and young children can induce childhood leukemia diseases, of which up to 80% of those become leukemia patients

  • Children's intelligence and memory will be greatly reduced

  • Increase the incidence of asthma

airDefender quantum dot photocatalyst removes formaldehyde

Using airDefender Advanced TVOC & Formaldehyde Removal Antibacterial Solution, after SGS test report, the removal of formaldehyde up to 99.0%, benzene and volatile organic compounds TVOC up to 96.4%.


airDefender uses the quantum dot photocatalyst produced by the self-assembly synthesis technology to form a transparent and high-performance film on the surface of the object, which can inhibit the growth of bacteria for a long time, and can also inhibit organic odors caused by bacteria, such as pet odor and smoke smell, toilet smell etc. In addition, the catalytic effect of the titanium dioxide film will continue to reduce formaldehyde, volatile organic compounds and other harmful organic compounds.

airDefender spray and coating have passed SGS oral acute toxicity test and skin irritation test. It is safe and harmless to human body and is suitable for families with children, elderly and pets. It will not corrode the surface of the material, and can be used on any materials.  Long-lasting and durable, daily cleaning agents such as alcohol, disinfectant and detergent will not damage the coating performance.

Few formaldehyde-removing formulas in the market have antibacterial functions at the same time , and have multiple German, Japanese laboratory and SGS test reports that prove that they can resist 99.9% of viruses and bacteria.
