Now the environmental pollution is particularly serious there are many families have installed air purifier, the air purifier in the end has no effect?
A better air purifier certainly works, but how effective is it? The following Xiaobian will take you to understand this problem!
Does the air purifier work?
1. The main pollutants to be solved in indoor air are inhalable particles, formaldehyde, viruses and microorganisms.
Inhalable particulate matter is the first indoor air quality problem. Due to the influence of haze weather, there is no way to open the window for indoor and outdoor air convection, and the PM2.5 value rises, which directly leads to the deterioration of indoor air quality.
China CDC test found that excessive inhalation of particulate matter can cause respiratory and lung infections.
2. The main method of air purifier to solve the inhalable particulate matter is to use HEPA high efficiency filter, according to the GB/T6165-1985 “high efficiency air filter performance test method” specified method.
The test of the Agison 5th generation ATP HEPA antimicrobial peptide filter showed that the filter had a removal efficiency of 99.998% for 0.1 and 0.3 micron particles. Air could pass through, but fine particles could not pass through.
Based on the above particle diameter, it can be concluded that the air purifier can completely remove inhalable particles.
3. Formaldehyde has been identified as a Group 1 carcinogen by the World Health Organization.
According to the report of the indoor air quality guide: the indoor formaldehyde content of safety standards is a cubic metre of 0.2 ㎎, excess or timeout will hurt lung function, and may be suffering from nasopharyngeal carcinoma or leukemia.
With the acceleration of urbanization, formaldehyde caused by building decoration, decorative materials, furniture and paint has attracted the attention of many families.
4. The way to solve the problem of formaldehyde in the air purifier is to use activated carbon adsorption to remove, because formaldehyde belongs to gaseous pollutants, can not be filtered by the way of dealing with the physical block of PM2.5, can only be purified by activated carbon adsorption principle.
We will GTF efficient activated carbon net for the test, first of all, the concentration of formaldehyde is increased to 0.5mg/m3, and then the machine is opened to a larger air volume to start purification.
After 30 minutes, the indoor formaldehyde reading decreased to 0.36mg/m3. After 60 minutes, the indoor formaldehyde reading decreased to 0.26mg/m3. 90 minutes after the start, the indoor formaldehyde reading dropped to 0.20mg/m3.
5. It can be seen that GTF highly efficient activated carbon mesh has an obvious ability to remove formaldehyde. In the continuous operation process of 90 minutes, the indoor formaldehyde concentration is reduced by more than half.
6. The killing of microorganisms and bacteria mainly relies on ultraviolet light.
Microorganisms are invisible to the naked eye and multiply quickly. Indoor garbage storage and food will breed bacteria. The following is a test result of our ultraviolet lamp in the air purifier.
7. It can be seen that GTF highly efficient activated carbon mesh has an obvious ability to remove formaldehyde. In the continuous operation process of 90 minutes, the indoor formaldehyde concentration is reduced by more than half.
8. Tests have shown that the ultraviolet light of the air purifier can effectively kill E. coli in 0.4 seconds and influenza virus in 0.3 seconds.
Air purifier in the end has no effect? The above small series made the answer after reading the answer, thank you will understand, in fact, as long as the quality is relatively good things, of course, there is a certain effect.
