Any particles less than PM 2.5 µm are classified as a Respirable Suspended Particle (RSP), the health effects and hazards with these small particles are great. RSP’s are particles that are small enough to evade mucosal capture by the protective Alia and mucosa of the human upper respiratory system and invade the deeper reaches of the lungs with serious health consequences.

One micron is equal to 1/25,400 of an inch or one-millionth of a meter. Particles are commonly measured in microns, a metric unit of length. There are 25,400 microns in one inch. This dot “.“ is approximately 1/64 of an inch wide and is equal to 615 µm.

The chart shown here provides a visual representation of the spectrum of common air contaminants and their measured sizes. Of particular importance when discussing indoor air quality solutions is how effective a product is at capturing/controlling contaminants PM 2.5 (Particulate Matter 2.5) µm or less in size.

Consistent breathing of pollutants can cause respiratory problems. Sensitive groups may experience difficulty breathing, shortness of breath, headaches, nose bleeds, nasal congestion and so much more.

Air quality data suggests that since 98% of airborne contaminants are less than one (1) micron in size, knowing the effectiveness of any product at controlling sub-micron particles is very important when making a decision on an air purification system for your home.

A micron or micrometer is used to analyze very small particles. The symbol for microns is “µm”, and the symbol for micrometer is “µ”. 1µm equals 1.00µ.

Not only that but it can lead to respiratory disease and other well-known respiratory-related illnesses such as Asthma, Chronic Obstructive Pulmonary Disorder (COPD), Cystic Fibrosis, Lung Cancer, and Sleep Apnea.

In fact, any particles of 5 µm 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 or health problems.
