This Mini Mate AS150mm is billed as the most powerful personal air purifier in the world and we’re almost gullible enough to go for it. You wear the thing round your neck, or clipped to a collar (preferably near your intake valves, see?) and it repels pathogens via an ‘intense electrostatic’ ion wind. Apparently it’s ‘clinically proven’ – don’t you just love that phrase? – and peer reviewed, so good for them we say. £79.00.

 If you or anyone you know suffer from Asthma, Hay Fever, allergies to perfume, smoke, mould and pet dander or are suffering from Rhinitis, Sinusitis, COPD, Cystic Fibrosis or just want greater protection from germs & bacteria then this might just be the most instantly beneficial product you have ever tried.
