Breath Easier With
True HEPA Filtration

True HEPA Filtration.

The High-Efficiency Particulate Air Filtration, also known as True HEPA in our portable HEPA filtration systems, keeps the air in any space clean and helps remove common airborne contaminants and particulate matter (PM).

Micron Sizes of Common Airborne Contaminants

The High-Efficiency Particulate Air Filtration in our portable HEPA air purifiers keep spaces clean and help remove common airborne contaminants and particulate matter (PM). True HEPA filters can remove contaminants as small as .3 microns in size. Microns (μm) are the units used to measure the standard size of any airborne contaminants or pollutants. For reference, see our micron chart below to help give a better understanding of airborne contaminants and particulate matter size your HEPA filtration solution will need to address.

Viruses Micron Size (0.001 to 0.3 Microns)

As the most microscopic particles around, viruses exist in all organisms. Particles of the SARS-CoV-2 (COVID-19) virus measure approximately 0.125 microns on their own, but they're often spread through biological aerosols as a result of coughing and sneezing. These range in size from 0.06 microns to 0.3 microns.

Bacteria Micron Size (0.3 to 5 Microns)

Bacteria can also cause a range of illnesses. There are many different varieties, which means the size can vary widely. Some bacteria are as small as 0.3 microns to 5 microns.

Mold Spores Micron Size (5 to 10 Microns)

Visible and often odorous, these spores range in size from 5 microns to 10 microns. HEPA air purifier systems work to reduce the number of particles floating through the air by attacking the spores.

Dust & Dust Mites Micron Size (1 To 10 Microns)

Household dust particles range in size from 1 microns to 10 microns, and they can cause respiratory illnesses and other issues when inhaled.

Tobacco Smoke Micron Size (0.3 To 1 Microns)

Particles of smoke from cigarettes and other types of tobacco are dangerous despite their small size. At 0.3 microns to 1 microns, particles from smoke are respirable, meaning you can breathe them in. An air purifier functions to trap particles in the HEPA filter.

Pet Dander Micron Size (1 To 5 Microns)

With dander ranging in size from 1 microns to 5 microns, furry friends tend to trigger allergy and asthma symptoms. Without an air purifier, dander remains airborne for hours.
