Although such results may be achieved during specific short-term laboratory testing, they are completely ‘unsubstantiated’ in relation to the ‘effectiveness’ of the device under actual operating scenarios for capturing particulate matter (PM), micro-organisms and toxic chemicals!

The remaining 50% of the cabin air is provided by the engine "bleed air". This air can contain fumes that contain volatile organic compounds (VOCs) which can create by chemical reaction an unpleasant smell, referred to by the airline industry as "odour". This "odour" however, can signal the presence of highly toxic substances, including carbon monoxide fumes.
