PM 2.5 : Particulate Matter below 2.5 Micron Size
Why Are PM 2.5 Dangerous?
Studies have found a close link between exposure to fine particles and premature death from heart and lung disease. Fine particles (PM 2.5) are also known to trigger or worsen chronic diseases such as asthma, heart attack, bronchitis, and other respiratory problems.
What makes up PM 2.5?
PM 2.5 is a complex chemical mix. PM2.5 can come from a variety of sources—traffic, forest fires, volcanic dust, burning of heating fuel (wood, coal, etc.) coal-fired power plants, industry, and more—and although some are emitted directly from these sources, much of it forms in the air when chemicals, such as sulfates, nitrates, and volatile organics react or condense to form fine particles. Because PM2.5 is so fine of particulates, they can travel hundreds or even thousands of miles.
There are also Indoor sources such as tobacco smoke, cooking (frying, sautéing, broiling) burning of candles or oil lamps, new carpet and or furniture. Chemical used in cleaning.
Solution: Select an air filter to remove a highest % of PM 2.5
Although a HEPA filter is the ultimate solution, it is normally impractical. Extremely high costs and most cases will not function in existing HVAC systems.
Starting around $20, FG IAQ Green Pleats will remove 95% of particulates 2.5 micron or smaller.
