Indoor air-conditioning units have six stages of air filtration

08 November, 2006

Six stages of air filtration are featured in a new range of high-wall indoor air-conditioning units from Toshiba.

An integral 6-stage air-filtration process is used in Toshiba’ latest high-wall indoor air-conditioning units. The filtration process includes the use of products based on Sasa, Zeolite and vitamin C. Research in Japan shows that this filtration technology gives exceptional anti-virus, deodorising and anti-oxidant characteristics. Sasa is a bamboo extract that deactivates bacteria and viruses. Zeolite (TiO2) traps particles and removes chemical pollutants. Impregnating the filter with vitamin C acts as an anti-oxidant. Filters are washable and regenerate their properties after drying in sunlight. The first process is a pre-filter that traps large particles and dust. The next stage traps airborne viruses and bacteria for elimination. Filters combine a bio-enzyme and Gingko extract, which has anti-bacterial and anti-allergy properties. They have a life of two years and can be cleaned with a vacuum cleaner and exposure to sunlight.

More refrigerant bans possible, says government

The government could tighten up the rules that restrict the use of global warming refrigerant gases including speeding up phase-out programmes and introducing new bans, according to a spokesman from the Department for Environment, Food and Rural Affairs (DEFRA).

Baxi research suggests schools strongly support heat decarbonisation

A survey conducted by Baxi of 200 state school estates managers, consultant engineers and M&E contractors has found that while enthusiasm for Net Zero and support for low carbon heating systems in schools is thriving, persistent barriers remain.
