Pollutant Particles Effect Indoor Air Pollution

A great portion of indoor air pollutants fall into the broad category of pollutant particles, also known as particulate matter. Particle matter control in the indoor environment is important for improving and maintaining good indoor air.

Particle micron chartEach cubic foot of air in your home or building can contain millions of particles. Particles are commonly measured in microns, a metric unit of measure. There are 25,400 microns in one inch. Approximately 98-99% of all particles by count are in the size range of 10 microns or less and the majority of harmful particles are 3 microns or less in size. A human hair can range from 40 to 300 microns. The average person breathes in about 16,000 quarts of air per day. Each quart of air breathed in contains some 70,000 visible and invisible particles. That's potentially a billion particles per day taken in by our respiratory system.

Particles 10 microns and smaller are generally known as respirable and typically remain in the lungs for the body to process. They will often lodge themselves in your mucous membranes and the linings of your lungs. Your body's immune system can be seriously be impacted by man-made chemical particles in this size range when inhaled. Breathing respirable particles long term can lead to severe allergic reactions including various chronic respiratory disorders.

IAQ Particle Facts

  • Visible particles (over 100 microns) can constitute as little as 1% of indoor air
  • Particle visibility depends on the eye itself, in other words, light intensity and quality, back-ground and particle type
  • Particles on furniture and those in a shaft of light can be 50 microns or larger
  • Particles of one micron or less adhere to surfaces by molecular adhesion, scrubbing is generally the only way to remove them
  • Larger particles tend to settle out of the atmosphere due to weight
  • Approximately 98-99% of all particles by count are in the size range of 10 microns or less, these particles tend to remain in suspension or settle out so slowly that only quality air cleaners such as HEPA air cleaners are effective in removing these particles
  • The average 1,500 square feet home can collect up to 2 pounds of dust particles per week
  • A 9' x 12' area rug can collect up to 10 pounds of dust particles per year

It is respirable particulate matter, due to poor IAQ, which is believed to cause many upper and lower respiratory disorders. It is not uncommon to measure more than 100,000 respirable particles per cubic foot with a laser particle counter in a typical home or small-building indoor environment.

It is these sub-micron particles which non-HEPA filtration devices DO NOT remove from the indoor environment. Any vacuum excluding HEPA or a central vacuum system actually recirculates these sub-micron particles causing a vicious cycle of pollutant particles.
