PM2.5 refers to particulate matter smaller than 2.5 micrometers (about 30 times thinner than a humain hair). These particles are so tiny that they can penetrate deep into your lungs and even enter your bloostream. We tested PM2.5 emissions during air frying using 2 setups: Without MyFibres papers: PM2.5 rose from 3 to 23 µg/m³ With MyFibres papers: PM2.5 rose only from 2 to 4 µg/m³ Cooking emissions are a major source of indoor air pollution. MyFibres offers smart, sustainabl
