Plasma Ionisation technology is proven sanitising technology that purifies the air and surfaces by emitting positive and negative ions. The technology deactivates suspended airborne mould, viruses, dust mite allergens and bacteria. The Ions are similar to positive and negative ions found in nature. The ions are surrounded by water molecules and are released into the air. The ions from hydroxide (OH) radicals are highly oxidising when they adhere to the surfaces of microbes, such as suspended allergens, bacteria, mould and viruses. They remove hydrogen from the surface proteins, breaking them down. The hydroxide (OH) radicals combine with hydrogen (H) to form water (H20) which is returned to the air.
