Defining Microns and How They Relate to Air Quality

Microns is a popular term within the air quality industry. We examine how a tiny unit of measurement for pollution can have huge health implications.

When we talk about our flagship product, the Venta Airwasher, or even our extremely efficient Kuuboid XL Max Air Purifier, we often mention the term microns. Within the air quality industry, microns are used as a term of measurement in describing the size of an airborne particle. For us at Venta, microns are critical to understand as it helps us to develop innovations in air-crafting technology.

Defining Microns

According to specifications set by the EPA, the national standard for “inhalable particles” is measured as particles 10 microns or smaller. Microns in this instance are a unit of measurement and an abbreviation for micrometer. A micron is one-millionth of a meter in size or about .00004 inches. For something to be seen by the human eye, it would need to be at least 5 microns. To put this into perspective, most, about 98%, of all airborne particles are less than one micron in size.

Microns are an important part of understanding air quality, in particular when it comes to studying air pollution and how it affects our health. PM 2.5 is the most commonly studied measurement of air pollution, as it can be extremely dangerous.

The EPA defines PM 2.5 as:

“Fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller. How small is 2.5 micrometers? Think about a single hair from your head. The average human hair is about 70 micrometers in diameter – making it 30 times larger than the largest fine particle.”

Particles this small are dangerous in that they can infiltrate your body’s natural protective layers (skin, mouth, nose, etc.) and settle deep into your lungs, and some may even reach your bloodstream. PM 2.5 often consists of a mixture of chemicals and other environmental pollutants like dust and dirt.

The negative health impacts of particulate matter have long been studied and have been linked to chronic respiratory conditions like asthma and decreased lung function, premature death people heart or lung disease, heart attacks, irregular heartbeats, prenatal problems, and more recently, links to dementia and Alzheimer’s.

Sensitive groups, children, the elderly, and people with asthma or chronic respiratory health issues are impacted by air pollution and particulate matter more than healthy groups, but the concern is still serious for all.

Eliminating Airborne Particles with Venta

Venta Airwasher and Kuuboid XL Max eliminate particles as small as 0.3 and 0.07 microns

While it is important to be aware of the dangers of outdoor air pollution and particulate matter, knowing the dangers of indoor air pollution is just as important if not more important.

Studies have shown that indoor air can be more polluted than outdoor air, and we spend roughly 90 percent of our lives indoors. This is why Venta is committed to developing air quality products that improve your air quality, and thus improving your quality of life.

In terms of microns, the Venta Airwasher (models LW15, LW25, LW45, Kuube L-T, and Kuube XL-T), is effective in eliminating airborne particles down to 0.3 microns in size. This is done without the use of filters, as the Airwasher system utilizes Cold Evaporation technology to simultaneously humidify and purify indoor spaces.

The Airwasher’s fan pulls dirty air filled with dirt, dust, pollen, and mold spores into the Airwasher’s water reservoir where they remain, and only pure moisturized air releases back into the room. This is the most hygienic form of humidification as there is no danger of over-humidification or pollutants like bacteria/viruses reentering the air.

The revolutionary Kuuboid XL Max features an all-new filter with unmatched filtration capabilities. The VENTAcel Nelior Filter is composed of a homogeneous layer of fibers with each fiber’s diameter measuring at roughly 100 nanometers. This special composition and mechanical stability results in the highest filtration efficiency, achieving 99.95% filtration of all particles equal to or small than 0.07 microns. The performance is unsurpassed by all other HEPA filters currently on the market.
