What does PM 2.5 mean on my air purifier?
What PM2.5 Means for Your Air Purifier
-
Tiny & Dangerous:Particles are smaller than a single strand of spider web, invisible to the naked eye, and can travel far and deep into your body.
-
Health Impact:Exposure is linked to asthma, heart attacks, lung damage, and other serious conditions.
-
Real-Time Indicator:The sensor detects these particles, and the display shows the level (e.g., 0-500), often with color-coded lights (blue for good, red for unhealthy).
-
Automatic Cleaning:A good purifier uses this data to ramp up fan speed to remove pollutants like cooking fumes, pet dander, smoke, and outdoor pollution.
Understanding the Numbers
-
Lower is Better:A reading of 0-12 µg/m³ is generally considered good, while levels above 35 µg/m³ can be unhealthy, especially for sensitive individuals.
-
Sources:Common sources include vehicle exhaust, industrial emissions, wildfires, candles, and even cooking.
