Polystar 90cm Digital Plasma Hood S90H38Using state-of-the-art plasma technology, Phiima Plasma Rangehoods will clean the air like no other recirculating rangehood on the market. The rangehood removes by-products of cooking – grease / odours / steam / heat with three phases of air purification Phase 1 Particle / Grease filter – grease extraction and dehumidification of cooking vapours by stainless steel mesh filters. Phase 2 Plasma treatment of pre-purified air – odour and scent molecule chains pass through an electrified plasma environment and undergo cold combustion. The molecules are disintegrated and oxidised through a plasma chemical reaction and converted into oxygen, carbon dioxide and water. Phase 3 Three layered charcoal filter – Odour molecules not captured in Phase 2 will be absorbed by the activated charcoal filter.Range hood extractor or exhaust hood is an elegant devise designed to give the kitchen that needed atmosphere away from the ancient, mechanically designed to hang above the stove or cooker top in the kitchen.
