Air Purification Systems

It has been estimated that up to 85 percent of all wood materials (such as particleboard or plywood) contain adhesives that in turn contain formaldehyde, and the World Health Organization has classified formaldehyde as a carcinogen. Unfortunately, it’s not enough to simply avoid eating those wood products – even the fumes given off by formaldehyde have been shown to pose a health hazard. Many people turn to keeping spider plants in their homes or offices, as they help neutralize airborne toxins, but now help could be coming from another source. German researchers have discovered that by adding special minerals to wood adhesives, those adhesives themselves can help clean the air.  Read More

The University of Copenhagen's Prof. Matthew Johnson, inventor of the Cleanair system

According to the University of Copenhagen’s Prof. Matthew Johnson, approximately one-sixth of the energy consumed in the world is used for heating, cooling and dehumidifying air in buildings. Because that air accumulates toxins and pathogens, he explains, it must constantly be expelled and replaced with new air that’s drawn in from outside. That new air must then be heated, cooled and/or dehumidified all over again. If only the air already in buildings could be cleaned up and reused, far less energy would be used on continuously conditioning fresh air. That’s why Johnson has invented the Cleanair system.  Read More

A new system based on old technology may allow for chemical-free CO2-scrubbing onboard sub...

Submarine crews could be breathing much healthier air thanks to miniscule devices based on 62 year-old technology. Currently, carbon dioxide is removed from the air in submarines through a reaction with chemicals such as calcium hydroxide. Chemical engineers from England’s University of Bath are collaborating with mechanical engineers from Duke University in the US, to develop a chemical-free filtration system. It utilizes seawater and tiny folded wire mesh rings known as Dixon rings.  Read More

Sanyo's home-use air purification system

Sanyo has just released a home-use air purification system that could save hayfever sufferers a lot of sniffles. Billed as the first of its kind in the United States, the Air Washer Plus is designed to use electrolyzed water technology to suppress bacteria and germs, reduce the amount of airborne pollen and allergy-causing dust, and eliminate unpleasant odors in the home.  Read More
