Formaldehyde, a colorless but highly irritating harmful gas, is recognized as a "life-threatening killer" indoors. Its release cycle can last as long as 3 to 15 years, and even if no peculiar smell is detected, there may still be a hidden danger of exceeding the standard. Especially in China, the problem of formaldehyde pollution in newly decorated families is particularly prominent, posing a more fatal hazard to children, pregnant women and the elderly with weak immunity — long-term exposure for children may increase the risk of asthma, impaired intellectual development and even leukemia; exposure for pregnant women is likely to cause miscarriage and abnormal fetal development; and for the elderly, it may induce chronic respiratory diseases and other health problems, seriously threatening the physical and mental health of the whole family. More notably, the 2022 version of the new national standard has strictly adjusted the indoor formaldehyde safety limit to 0.08mg/m³, and the safety red line for maternal and infant groups is even as low as 0.05mg/m³. Formaldehyde treatment has become an essential link for moving into a new home.
Tongli x Chinex - Photodegradable Formaldehyde Home Health Film ：Home Formaldehyde Removal Black Technology, Guard Every Breath
The core of the product adopts nano-TiO₂ (titanium dioxide) as the catalyst for photocatalytic reaction, innovatively incorporates Ag-TiO₂ composite photocatalytic materials, and optimizes dispersion technology to make it evenly adhere to the film surface. It can not only be quickly activated under ultraviolet irradiation, but also respond to daily visible light (fluorescent lamp, natural light), without the need for additional ultraviolet equipment, and is suitable for various indoor scenarios. After activation, the catalyst will absorb light energy, generate highly oxidizing hydroxyl radicals and superoxide anions, accurately attack formaldehyde molecules in the air, and completely decompose them into harmless and odorless CO₂ (carbon dioxide), H₂O (water) and inorganic salts. There is no residue of intermediate pollutants, eliminating formaldehyde hazards from the source, preventing secondary pollution, and truly achieving green environmental protection and efficient formaldehyde removal.
Compared with traditional formaldehyde removal products such as sprays and air purifiers, this product has multiple advantages: first, high formaldehyde removal efficiency and fast reaction speed, with a formaldehyde degradation rate of more than 80%, which can quickly approach and meet the new national standard safety limit; second, long-term durability, the designed service life of the film layer can reach 3 to 5 years, perfectly matching the 3 to 15-year formaldehyde release cycle, without frequent replacement; third, diverse functions, in addition to the core formaldehyde removal effect, it can also effectively remove mites, eliminate decoration odors, and release a large number of oxygen-enriched ions to improve indoor air quality and make breathing fresher; fourth, outstanding cost performance, no additional energy consumption is required, and long-term formaldehyde removal can be achieved with one installation, whose cost is much lower than that of traditional repeated treatment methods.
As a health film specially designed for home scenarios, the product balances practicality and aesthetics, with the core characteristics of high light transmittance and low haze. After being attached to the glass, it does not block light or affect the field of vision. It can not only exert the formaldehyde removal effect, but also improve the texture of the home space without damaging the original decoration style.
It is widely applied to various glass surfaces such as new homes, offices, show windows, maternal and infant rooms, and elderly rooms. Whether it is a newly decorated home or an office space that needs to optimize air quality, it can be quickly adapted to create a safe, healthy and comfortable breathing environment for family members and employees, truly realizing "one film, purify the whole house, and protect the whole family".
