Preço normal $149.00 $0.00 Preço unitário por

This PM 2.5 Indoor Air Quality Monitor is equipped with an instant measurement PM 2.5, and also measures ambient humidity and temperature.

Plus, with its WiFi feature, you can access real-time and historical data of PM 2.5 readings from your iOS or Android smart phone app. One simple button on the top allows for easy operation, switching between functions like US AQI or CN AQI.

PM 2.5 refers to particulate matter (PM) that has a diameter of 2.5 micrometers or smaller. These tiny particles are a subset of the larger category of particulate matter, which includes a wide range of solid and liquid particles suspended in the air.

PM 2.5 particles are very small and can remain airborne for extended periods, allowing them to be easily inhaled into the lungs. Due to their small size, they can penetrate deep into the respiratory system and even enter the bloodstream. This makes PM 2.5 a significant public health concern.

The primary sources of PM 2.5 include:

  1. Combustion of fossil fuels: Emissions from vehicles, power plants, and industrial processes that burn coal, oil, and gas.
  2. Residential heating and cooking: Wood-burning stoves, fireplaces, and cooking can release PM 2.5 particles.
  3. Agricultural activities: Plowing, tilling, and crop burning can contribute to PM 2.5 emissions.
  4. Wildfires: Smoke from forest fires can release large amounts of PM 2.5 into the atmosphere.
  5. Industrial processes: Various industrial activities can generate PM 2.5 particles as by-products.

Exposure to PM 2.5 has been linked to numerous health problems, particularly respiratory and cardiovascular diseases. Vulnerable groups such as children, the elderly, and individuals with pre-existing health conditions are at higher risk. In response to these health concerns, many countries have set air quality standards and regulations to limit PM 2.5 concentrations in the atmosphere and protect public health.
