NOx is also produced by diesel fumes (the Diesel-gate scandal comes to mind), but also by other fossil-fuels, which are the main man-made source of this dangerous pollutant. Power plants, vehicles, ships, cement manufacturing are some of them, but also forest burning.

Nitrogen oxides are part of the vast VOC family (Volatile Organic Compounds) and they include notorious harmful pollutants such as Benzene, Formaldehyde, Acetone and hundreds more. They are also found in cosmetics, air fresheners, glue, paint, solvents, aerosol sprays, pesticides, and other common adverse health effects include: eye, nose and throat irritation, headaches, nausea, damage to liver, kidneys and the central nervous system, cancer (source: EPA). Symptoms of excessive exposure to VOCs include conjunctival irritation, allergic skin reactions, dyspnea, fatigue, dizziness.
ESA (The European Space Agency) tasked the Sentinel 5 satellite to monitor NOx pollution around the globe and the results were anything but scary. China, Europe, North America’s cities like New York or even California highlight excessive levels of dangerous NO2.

More and more scientific studies link excessive NO2 pollution and cardiovascular diseases: “…Data confirms the existence of an association between NO2 and cardiovascular disease. Apart from haemorrhagic stroke…” Reducing or eliminating NOx exposure and VOC pollution can improve your health and helps your immune system to fight the adverse effects of a variety of pollutants.

Simple HEPA filters are largely ineffective against NOx and VOC pollutants. This is Photocatalysis' territory. In fact, this chemical process destroys these families of pollutants and it is highly effective against gases, where HEPA filters cannot do anything to stop those harmful pollutants.
Below you can see how effective NOx depletion is with the use of Brid Air Purifier 'LED Activated Advanced Photocatalysis' Filtration (L.E.A.P.) proprietary technology. What is see is depletion and destruction of NOx, which turns into mostly vapor.
