A British company continues to offer a portable decontamination device that should come as breath of fresh air to a flu-weary public.

In fact the unit duplicates the ability of "outdoor fresh air" to destroy a wide range of airborne viruses and bacteria including the H5N1, influenza, and SARS, all within minutes of contact, according to Tri--Air Developments. "It's almost so good that nobody is going to believe it," admits Martin Wyatt, of the Buildings Research Establishment, a quasi-government agency that has been involved with the development.

The London based company claims it has already produced a prototype compact enough to fit in the ventilation systems of trains and aircraft (10 inches by 5 inches), and expects to follow up with a personal belt, clip-on unit, according to Tri-Air technical director Alan Mole.
