Air is the most essential element to our wellbeing. Breathing clean air, we benefit every cell from mind to body.

The Air We Breath

WHAT IS PARTICULATE MATTER?
Particulate Matter (PM) is the named given to a complex bunch of small microscopic pollutants that float in the air. These include pollution, dust, pollen, pet allergens, viruses, bacteria, mold and many more. When inhaled they can cause significant health risks.

How is particle size measured?
Particulate Matter is commonly measured in microns, or a micrometer. One micron is one-millionth of a meter.

Particulates are are often divided into two basic groups based on their size: PM10 (coarse) and PM2.5 (fine). Check out the chart at the bottom of the page that identifies the size range of a few of the most common problem pollutants and how efficiently O2 Nose Filters can protect you from each of them.

What About PM10 And PM2.5?
Particulates identified as PM10 and higher comprise mostly of the allergy causing airborne pollutants such as pollen, mold, dust, etc. Finer Particulates in the PM2.5 group can travel further into the lungs and thus potentially causing damage at a deeper level.

O2 Nose Filters, using 3M’s patented electrostatic technology, capture over 70% of PM2.5 and nearly 100% of PM10.

“MORE THAN 9 OUT OF 10 OF THE WORLD’S POPULATION LIVE IN PLACES WHERE AIR POLLUTION EXCEEDS SAFE LIMITS.”

WORLD HEALTH ORGANIZATION STATISTICS

“More than 150 million Europeans suffer from chronic allergic diseases and the current prediction is that by 2025 half of the entire EU population will be affected.”

EACCI, 2016

“Airborne Pollution at PM2.5 ranks 5th worldwide among all risks (for premature death), including smoking, diet, and high blood pressure.”

State of Global Air, 2017

“In 2015, long-term exposure to PM2.5 contributed to 4.2 million deaths and to a loss of 103 million years of healthy life worldwide.”

State of Global Air, 2017

“In 2010, 11.1 million visits to physician offices resulted with a primary diagnosis of allergic rhinitis.”

Particle Size vs. o2 Filtration Efficiency

The eye can see particles down to about 40 microns in size but there are many smaller and potentially harmful ones in our immediate air. O2 Nose Filters utilize 3M electrostatic technology to effectively capture pollutants, allergens, viruses and other particulates at the PM10 and PM2.5 micron level. Keep in mind The Condensation Effect makes O2 filters even more effective.

About the Condensation Effect *

Particulate sizes as shown in the chart below are typically given as the ‘dry’ size.  But pollen, molds, bacteria, and viruses are never ‘dry’ or else they would die.  They constantly absorb moisture from the air around them which significantly increases their size by 80–1000%.  The technical term for this process is The Condensation Effect, and because it greatly increases the size of particles, it further increases the effectiveness of the filtration technology in the O2 Nose Filters to well beyond the minimum ‘dry particulate’ efficiency statistics, conducted in a laboratory setting, shown below.

Results

Independent laboratory tests of the electrostatic 3M filtration material utilized in the O2 Nose Filters demonstrated better than 70% efficiency for particulates measuring 2.5 microns and over 99% for particulates 10 microns and greater.

Variables

It is good to keep in mind that Particle Speed and The Condensation Effect will influence the efficiency of the O2 Nose Filters. The latter always in favour of even better protection.
