Photocatalytic technology is simple. By activating a photocatalyst with UV light, an oxidation process is set in motion that destroys harmful air pollutants.
Yellow Collective’s patent pending technology works at the molecular level when activated; producing no harmful by-products and destroys organic molecules and air pollution.
Most filters operate from 2.5 to 10 nanometres often leaving smaller particles, pathogens, and pollutants behind in the air as they pass through the filter.
At Yellow Collective, we want to do better. Our technology operates at the lower range of the nano scale. And by capturing and destroying the smallest, most harmful pollutants from internal and external environments, what’s left behind is clean air.
*HEPA filters operate between 300 and 500 nm.
Technology that eliminates harmful air pollution
Under controlled tests, our fan system produced an average reduction of 30% Particulate Matter (PM) on the smallest nano scale: Ave 30% PM1, PM2.5 and PM 10.

Technology to remove Carbon Dioxide
Our photocatalytic technology treats the CO2, either by breaking of the bond between the carbon & oxygen and oxidising it. Both of these processes are environmentally benign: no harmful by-products like carbon monoxide, nitrates, nitrous acids, or ozone are produced.
Our Clean Air System is akin to planting 1 tree, or 1 tonne of CO2 per annum. Fitting a building with many fans could not only help human health and performance, it would be the equivalent of planting a forest over night.
Tackling the Transmission of SARS-CoV-2
It is unambiguous that viral protection measures must include addressing airborne transmission. The Centre for Disease Control in the US (CDC) has stated “The principal mode by which people are infected with SARS-CoV-2 (the virus that causes COVID-19) is through exposure to respiratory droplets carrying infectious virus”.
It has also been found that COVID-19 seems more severe in areas with high concentrations of pollution.*
Our clean air solution employs two well accepted and scientifically referenced methods to indiscriminately destroy or neutralise airborne viruses and infections like COVID-19:
We not only use a photocatalytic compound to destroy pollution, our fan incorporates a proven germicidal UVC lamp. This UCV light has a 99.99% kill rate and widely found and used to inactivate H1N1 influenza and other coronaviruses.
As air passes through our fan system at least 10x per hour to effectively clean the air to cleanroom standards, it significantly reduces the risk of viral transmission.
