The HEPA filter which traps the micro particles like PM2.5 is the reason for this steep pricing. Air purifier without a HEPA filter is as good as an air conditioner — not worth it. PM2.5 (particles with a diameter of 2.5 micrometres or less): these particles are so small they can get deep into the lungs and into the bloodstream. There is sufficient evidence that exposure to PM2.5 over long periods (years) can cause adverse health effects. Note that PM10 includes PM2.5. Potential health effects from exposure to particulate PM10 and PM2.5 monitoring is not conducted in many of the non-EU countries, which makes it difficult to assess exposure in those parts of the Region. Period of coverage PM10 and PM2.5 data used in this analysis cover the period from 2004 to 2011.

They are often catalogued as 'floating dust', but are best known as particulate matter (PM). 2021-02-05 · Many of you will have heard people talk about PM10 and PM2.5, but what exactly is it and why should it be measured? We look at the importance of particulate matter, its impacts on human health, and the best ways to measure it to keep people safe. PM2.5 also damages the environment by increasing acidity in the soil and water bodies, which in turn affects their ability to produce food and support life. 5) How can I protect myself against PM2.5?
