Air purifier detection.
An air purifier is an electrical device that can purify indoor air, mainly used to remove indoor dust, bacteria, viruses, odors and other pollutants and improve indoor air quality. According to different purification technologies and working principles, air purifiers can be divided into many types, including negative ion purifiers, ozone purifiers, high-voltage electrostatic purifiers, plasma purifiers, etc. Air purifier testing is the testing and evaluation of the performance, safety, hygiene, and other aspects of the air purifier to ensure that the performance and safety of the air purifier meet the relevant standards and requirements.
1. Electrical safety testing, including electrical safety regulations, electromagnetic compatibility and other aspects of testing.
2. Air purification effect detection, including particulate matter, formaldehyde, toluene, benzene, ammonia, TVOC and other indicators.
3. Detection of cumulative purification capacity, including the detection of particulate matter, formaldehyde and other indicators.
4. Power testing, including the detection of purification energy efficiency and other indicators.
5. Noise detection, including the detection of sound power level and other indicators.
6. Sterilization performance testing, including Staphylococcus albicans, Staphylococcus aureus, Escherichia coli, air natural bacteria, Aspergillus niger, bacteriophage, influenza, intestinal and other sterilization rate testing.
7. Detection of harmful substance release, including ozone, TVOC, PM10, ultraviolet rays, ozone 24-hour increment and other indicators.
8. Removal rate detection, including formaldehyde removal rate, toluene, benzene, TVOC, particulate matter, PM25. Detection of CO2, NO2, SO2 and other indicators.
9. Detection of negative ion concentration, including detection of negative ions and other indicators.
10. Deodorization performance testing, including sulfur dioxide, nitrogen dioxide, ammonia, hydrogen sulfide, acetaldehyde, acetic acid and other indicators.
