‘So how do we protect your lungs?’
Our filters are produced from the highest quality, highly efficient absorption material with micropore structure, fast resorption, and excellent purification efficiency. The filters are heat resistant, acid resistant, and alkali resistant with no smell.
The adsorption of organic particles is up to ten times higher than general activated carbon. Organic particles in gas, aldehyde, hydroxybenzene, and alkene are filtered because of the structure of the micropores. They also feature excellent adsorption of up to 95% of inorganic gases such as No, No2, So2, H2S, HF, HCL, CO and CO2.
Studies have proven that active carbon filters can remove all forms of pollutants. Multiple materials are required to attract the different molecules within pollutants. That is why active carbon filters have numerous properties. Activated charcoal has millions of pores that create immense surface area to which chemicals can adhere. The negatively charged ions within active carbon work similar to a magnet that attracts the positive ions like PM2.5 particles, heavy metals and other toxins.
To test the filtration efficiency of the filters, our manufacturer used the Automated Filter Tester 8130. This is the same instrument that is used at NIOSH to test the efficiency and penetration of aerosols. The results showed that the active carbon filter filtered 100% of PM10 particles, more than 99% of all PM2.5 particles, and 95% of PM0.3 particles.
Using the Met One Instrument AeroCet 531S, the filters were also tested independently.
The study was conducted from 8AM till 4PM for one day in the city center of Hanoi, VietNam. The laboratory had open windows, and was located on the 4th floor. The different sizes of pollutants in the room were collected simultaneously: PM1, PM2.5, PM7, PM10 and TSP, and were measured before and after the mask was tested. Sample masks and filters were measured for a total of 20 minutes each, and the instrument provided data every 2 minutes.
Results showed that the activate carbon filter has a filter efficiency of up to 99.8%. On average while the mask was fit tested on a subject, the filtration rate of PM2.5 particles was 95%. The gas mask filters filtered out 100% of PM2.5 particles through the microfiber filter and chemical cartridge, while 99.7% of particles were filtered while fitted on a subject.
The temperature was 25°C, and humidity was 89%.
The AEROCET 531S is a full–featured, battery operated, handheld mass monitor or particle counter. It simultaneously measures 6 mass concentration ranges (PM1, PM2.5, PM4, PM7, PM10 and TSP) or five particle count sizes (0.3µm, 0.5µm, 1.0µm, 5.0µm and 10µm).
