The compact GoPure GP5212 air purifier has been released from Philips. It can remove up to 100 different types of pollutants —including viruses, allergens, bacteria and exhaust gases — and neutralize unpleasant odours in a vehicle. The purifier uses a special 3-layer filter technology In a three-stage process, it captures large particles, uses a HESA (high efficiency sorbent agent) filter then a HEPA filter that removes over 99 per cent of airborne bacteria and virus. The purifier is designed to operate automatically without needing driver attention. When plugged into the vehicle’s auxiliary power outlet, the unit turns on and off with the vehicle’s ignition. Its two-speed fan can be easily adjusted by the power button. An indicator light signals the need for a filter replacement. Weighing less than two pounds, the purifier is 7 inches long and wide and less than 3 inches high.
