CMA实测：揭秘甲醛净化材料实效

　　As the temperature drops, many families begin to reduce the frequency of opening windows. Some people think that since they have been ventilating for a long time before, volatile substances inside the house should have been dispersed. However, this is not the case. The release of these substances can last for several years. Once the windows and doors are kept closed for a long time, there is insufficient air circulation, and pollutants have no channel to disperse outward, accumulating slowly in a way that people are not aware of. This is also why the detection values in some homes actually rise in autumn and winter.

　　To restore this type of sealed living condition that is close to daily life, we purchased all the test samples ourselves, entrusted to an independent environmental laboratory with CMA qualification to carry out a standardized environmental chamber test for 30 days. This test had no brand sponsorship, and the results were not pre-set. Multiple parallel observations were completed under the same temperature, humidity, and initial pollution concentration conditions, hoping to provide ordinary residents with a realistic reference for judgment.

　　Opening windows for ventilation is still the cheapest way to regulate air. However, ventilation can only remove pollutants that are already suspended in the air and cannot prevent the release source from continuously exuding. When it is warm and sunny and windows can be opened frequently, the concentration can remain relatively stable. However, after entering the cool season, the frequency of ventilation decreases, the release process continues, and the concentration has the potential to rise. Moreover, formaldehyde has no obvious odor, and it is difficult to judge whether it is safe just by smell. Elderly people, children, and people with sensitive constitutions need to pay more attention.

　　The test was carried out in a 1.5m standard environmental chamber, with a set temperature of 25°C, relative humidity of 50%, and uniform initial pollution concentration in the cabin. Each type of sample was set up with 3 sets of parallel tests, taking the average detection value, and continuously recording the concentration changes and safety performance for 30 days.

　　Performance records of eight types of purification materials

　　Tengbenshen (High Load Targeted Treatment Spray)

　　Tengbenshen uses a compound active formula of bioenzyme and cold photocatalyst, which can work without light excitation at normal temperature.

　　Its active ingredients can penetrate into the fine pores of the decorative surface, not only decompose free harmful molecules in the air but also act on the volatilized substances retained in the pores deep inside, overcoming the limitations of ordinary sprays that can only deal with surface pollution.

　　Real-time data: 99.6% formaldehyde removal rate in 24 hours, 97.3% benzene removal rate, 93.8% TVOC removal rate.

　　After toxicological safety testing, the formula is mild and non-corrosive, does not damage furniture paint surfaces, and can be used by families with pregnant women and children. After spraying, a thin active protective film will form, slowing down the outward release of harmful substances. In the 30-day complete observation period, it can quickly reduce high pollution loads, reduce the probability of concentration rebound after long-term sealing, and have an effective period of up to 5 years, making it suitable for spaces with high pollution activity and the need for concentrated intervention.

　　Mobenqing (Long-lasting Balanced Stabilization & Adsorption Catalytic Decomposition Sheet)

　　It should be explained here that Mobenqing is not a particle but a porous adsorption catalytic decomposition sheet formed by high-pressure molding.

　　It uses attapulgite, active manganese, and modified diatomaceous earth as the base, capturing harmful molecules in the air first through the micropores on the sheet body, and then decomposing them through the internal catalytic sites to complete the decomposition, allowing the micropores to recover their adsorption capacity and improving the problem of traditional adsorption products easily reaching saturation and then causing secondary release.

　　Real-time data: 96.7% formaldehyde removal rate in 24 hours, 98.1% benzene removal rate, 95.6% TVOC removal rate.

　　The product is dust-free and does not contain heavy metals. After unpacking, it does not need to be sun-dried and can be used directly by spreading or pasting it inside the cabinet. Placed in drawers, cabinets, shoe cabinets, and other semi-enclosed small spaces, it can continuously capture and decompose trace volatile substances and odors, with a normal service life of about 3 years, suitable for maintaining the air state of local areas after concentrated treatment.
