Pollutant Particles Effect Indoor Air
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.
Each 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
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
- 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.
Controlling Pollutant Particles Requires a Proven
You can drastically reduce pollutant particles by implementing a good
system for their removal and control. The T.E.A.M. (Total Environmental Approach Methodology)
system can turn sick houses into indoor havens starting in the first seven days. Click Here to obtain this proven system for your own home.
The methods and techniques shared in this valuable book are based on 25 plus years of
research and works with just about any housing structure anywhere in the world! The Sick House Solution formula
is a simple step-by-step system that can help remove these
damaging particles from your home for good!
