The e2f filter - Performance Test

Particulate Matter - 2μm scale


PM Particulate Matter is categorized as “PM10” and “PM2.5”. PM10 is 10 μm (micrometers) in diameter. PM2.5 is even smaller, measuring 2.5 μm or less. They are both major air pollutants and are well known to be harmful to humans due to deep penetration of these particulate matter into the lungs because the respiratory system is not capable of filtering them out. An example of the damage from PM2.5 and PM10 can be seen from recent news when in October 2013, the concentration of PM2.5 in China soared to 400 μg/m³, significantly exceeding the World Health Organization’s (WHO) guidelines (PM2.5 guideline values: 10 μg/m³ annual mean, 25 μg/m³ 24-hour mean) and becoming a significant threat to human safety. In addition, cigarette smoke particles range from 0.05 μm to 0.5 μm in size, making it difficult to capture these tiny particles. Even HEPA filters only guarantee the filtration of 99.97% of particulate matter 0.3 μm in size, which means standard air purifiers will not be able to effectively clear out cigarette smoke. Clair Air Purifiers, on the other hand can collect ultrafine particles smaller than 0.3 μm (it can capture particles smaller than 0.1 μm).

Particulate Matter - smaller than 2μm scale

This chamber test demonstrates this fact by collecting ultrafine particles smaller than 0.3 μm by removing most of the cigarette smoke in 1 minute. In addition, our e2f filter can effectively remove up to at least 99.97% of all PM10 and PM2.5 in the air. Check out the video below. (Results may vary according to test conditions.)
