Metamasks filters feature an exclusive New Zealand nanofibre tested by NELSON LABS in June 2020.

As shown in the lab results below, our exclusive 'hyperloft' nanofibre captures airborne particulates down to a size of the smallest viruses (0.1 microns), while meeting or exceeding international standards at 2.5 microns (99%).
With electrospun nanofibre filters it is common for the filtration efficiency to be higher as the particle size decreases. This mode of action is due to diffusion and electrostatic attraction. Nanofibres are therefore often able to filter small particles better than larger ones due to enhanced electrostatic attraction.
Some particles in the nano range (around 0.2 - 0.3 μm) have been proven to be difficult to filter as they do not behave according to normal capture mechanisms (i.e mechanical efficiency, or the “sieve effect”). These particles are referred to as the most penetrating particles size (MPPS). Particles that are MPPS or smaller are captured via diffusion (or electrostatics) while larger than MPPS are usually captured via mechanical filtration. Electrospun nanofibre is an excellent filter media due to the combination of both particle capture mechanisms.
We think this was observed more readily on the Nelson Labs test because there was a calibrated amount of each particle size, and very accurate equipment.
We guarantee our proucts provide safe and effective protection from polluted air conditions when used correctly however this product is not medically proven to prevent diseases.
The Dangers of Pollution
Air Pollution is THE MAJOR CAUSE of death and lung disease on the planet. By UNDERSTANDING what pollutants are and the problems they cause, read the following information and whenever necessary, WEAR YOUR METAMASK!
Why does Particulate Size Matter?
The term Particulate Matter 2.5 (PM2.5), refers to tiny particles or droplets in the air that are two and a half microns in width. One micron is one-thousandth of a millimeter, there are 25,400 microns to one inch, up to forty times smaller than a human hair. Particles less than 2.5 microns are so small that several thousand of them could fit on the period at the end of this sentence.
PM2.5 particles in the air reduce visibility and cause the air to appear hazy when levels are high, especially on days with little or no wind to dissipate toxic particulates. Thankfully, many cities around the planet issue a Health Advisory Warning when PM2.5 concentrations in outdoor air are expected to be unhealthy or harmful. However if you walk, ride, or take public transport in cities or regions with PM2.5 particulates in the air, you are likely at risk.

Small enough to enter your bloodstream?
To put a micron into a perspective you can wrap your brain around, there are roughly 100 microns in the width of a human hair. And the airborne particles we are referring to are many times smaller than this.
Particles in the PM2.5 size range are able to travel deeply into the respiratory tract, reaching the lungs. Exposure to fine particles can cause short-term health effects such as eye, nose, throat and lung irritation, coughing, sneezing, runny nose and shortness of breath. Exposure to fine particles can also affect lung function and worsen medical conditions such as asthma and heart disease.
Scientific studies have linked increases in daily PM2.5 exposure with increased respiratory and cardiovascular hospital admissions, emergency department visits and deaths. Studies also suggest that long-term exposure to fine particulate matter may be associated with increased rates of chronic bronchitis, reduced lung function and increased mortality from lung cancer and heart disease. People with breathing and heart problems, children and the elderly may be particularly sensitive to PM2.5.
When outdoor levels of PM2.5 are elevated, going indoors may reduce your exposure, although some outdoor particles will come indoors. If there are significant indoor sources of PM2.5, levels inside may not be lower than outside. Some ways to reduce exposure are to limit indoor and outdoor activities that produce fine particles (for example, burning candles indoors or open burning outdoors) and avoid strenuous activity in areas where fine particle levels are high.
Metamasks effectively capture 99.99% of dangerous airborne particles at PM2.5 and up to 99% of particles down to size PM.01
