Activated Carbon Filter Face Mask PM 2.5



Dust Proof Activated Carbon Filter for Anti-Pollution Face Mask PM 2.5

Although mostly invisible to the naked eye, the air we breathe is full of tiny particles of; chemicals, soil, smoke, dust or allergens, in the form of liquids, gases or solids. When we burn fossil fuels for energy use and production. The release of gases and chemicals are creates air pollution, posing a risk to human health and the planet as a whole. These minuscule airborne hazards are referred to as particulate matter, or PM.

There is a lot of conflicting information. Do surgical masks capture coronavirus particles? Media outlets like US National Public Radio have claimed they don’t. Fortunately, scientists have already accumulated hard data on air pollution masks that can answer these questions.

Where does PM come from?

The amount of particulate matter in the air at any given time depends on the environment you find yourself in. These particles are released from a variety of sources both indoors and outdoors. When inside, PM levels are typically the same or lower than outside. 

Here are a few things that increase the levels of particulate matter floating around an indoor space: 

  • smoking
  • cooking
  • burning candles or fires
  • using kerosene heaters
  • diffusing essential oils
  • cleaning using common chemical products 
  • opening doors and windows to outdoor polluted environments
  • using hairsprays, aerosol room freshers or deodorants 

How Big Are Coronavirus Particles?

First things first: we need to know how big the coronavirus is. Scientists have already used electron microscopes to measure how big the corona virus is. Coronavirus particles (fancy scientific name “virions”) are spheres with diameters of approximately 0.125 microns (125 nm). The smallest particles are 0.06 microns, and the largest are 0.14 microns.

What are the negative effects of exposure to PM2.5?

Depending on how healthy you are in general, PM2.5 will have different long and short term negative health effects. When exposed to levels of PM2.5 between to moderate – hazardous range, one may experience the following effects:

  • shortness of breath
  • eye, nose and throat irritation
  • excessive coughing and wheezing
  • diminished lung function and lung disease
  • diminished heart function, sometimes resulting in heart attack
  • asthma attacks
