These excellent new energy-miser light bulbs not only last longer, use less power and are cheaper to run than standard light bulbs but, amazingly, they also clear the air of allergens! An ingenious ioniser built into the bulb emits 3.5million negative ions per cubic centimetre every second it is switched on, removing dust, mould spores, smoke, pet dander and pollen over a 3 metre square area so quickly you can almost see the particles disappearing. The benefits of breathing ionized air also include enhanced quality of sleep, improved concentration and alertness, skin condition, mood and sense of wellbeing.
