The present invention provides a method and apparatus (1) for improving air quality within an enclosed space. The apparatus (1) provides at least three molecular sieves (7, 8, 9) that contain zeolite material to treat the air to remove toxins such as suspended particles; carbon dioxide, carbon monoxide, nitrogen dioxide, bacteria, formaldehyde, total volatile organic compounds, radon, ozone, toxic mould and organic odour causing compounds. The apparatus (1) uses the sieves (7, 8, 9) such that one of the sieves is locked and retaining air, substantially immobile within, for a period of not less than 2 seconds to allow the zeolite material to break down the compounds and release the individual natural elements.
