Air Revival

AirRevival’s revolutionary Electronic Air Cleaning (EAC) technology takes advantage of electrostatic fields to literally draw pollutants out of the air. Since fine particles naturally have a positive charge, they can be attracted by a negatively charged electrostatic field. By creating just such a field, a single AirRevival unit can capture 90% of particles within an average-sized bedroom, using minimal electricity (approximately 1W).
