This article is the first of a two part series to help us better understand how carbon nanotubes can be used to filter and purify our most vital resources. Clean air and drinkable water are essential to human life, and maintaining each of them is an ongoing challenge. The safety of the air we breathe is very high in everyone’s thoughts recently, with the (COVID-19) Coronavirus quickly spreading across the world; therefore, it seems natural for us to focus first on air purification.

Airborne viruses and other hazards that come in the form of microscopic or nanoscopic particles present a significant challenge. Many toxins and harmful particles can become airborne; fortunately, this means that if we are able to circulate that air through some kind of treatment or cleaning station then the air will bring the toxins along with it to be trapped. There are two basic methods used to clean air: mechanical filtration and purification using electric fields or light. Each method can be tailored to fit the specific hazard you want to remove, whether that be viruses, odors, or pollutants. Of course, no single option is designed to combat every hazard. and there is a need to further develop these methods to improve efficiency and the range of toxins that can be dealt with.
