If you’re looking to improve the quality and freshness of your indoor air, an electronic air cleaner (EAC) may be your answer. An EAC is a sophisticated air filtering device that is installed as part of your HVAC system. It uses electricity to attract particles and causes them to “cling” in a way that’s similar to static cling on your clothes — although in a much more powerful way.
How an EAC Works
Standard filters work by impingement or straining. Big particles in the air simply can’t fit through smaller openings. This limits the size of particle that can be filtered, of course, based on the size of the filter openings. Impingement filters can only catch larger particles.
But an EAC operates through a transformer, with power applied to the air stream, creating a positive charge to particles. On the receiving end, the collecting plates or the negatively charged media capture the particles like a super-powered “static cling.”
