98% OF ALL INDOOR AIR PARTICLES ARE LESS THAN ONE MICRON IN
A micron is a metric measurement used to analyze very small
particles. One micron is equal to 1/25,400 of an inch or one millionth of a
meter. The chart on the right provides a visual representation of the spectrum
of common air contaminants and their measured sizes in microns.
Of particular importance when discussing indoor air quality solutions is how
effective a product is at capturing/controlling contaminants 2.5 microns or
less in size. Any particles less than 2.5 microns are classified as a
Respirable Suspended Particle (RSP) and the health hazards with these small
particles is great. RSP’s are particles that are small enough to evade
mucosal capture by the protective cilia and mucosa of the human upper
respiratory system and invade the deeper reaches of the lungs with serious
health consequences. In fact, any particles of five microns or less are
considered a definite inhalation hazard because of the inability of the human
body to filter effectively these particles from the lungs.
Allergenic particles, infectious agents and toxic gases can cause allergic
reactions, headaches, sickness and many other illnesses. Since 98% of airborne
contaminants are less than one (1) micron in size, knowing the effectiveness of
any product at controlling submicron particles is very important when making a
decision on an air purification system for your home.
