The MicroClean 95 uses a patented Carbon Graphite electrical grid system to create an electro-magnetic field inside each air cleaner. This hybrid high-efficiency polarized media technology combines two cleaning processes for maximum efficiency. The unit contains multi-layered certified media pads that become charged with powerful electrical energy. When air passes through your heating and cooling system, 0.3 microns or smaller particles get trapped in these charged pads through electro-magnetic attraction. The Carbon Graphite charging system is the secret behind this air cleanerís high performance. Unlike standard disposable filters that only catch larger particles, this technology actively pulls harmful contaminants out of your air. The system has been ASHRAE 52.2 tested and proven to remove 95% of particles at both 1 micron and 0.3 micron sizes. The unit operates on low-voltage electronics, consuming less than 2 watts of energy while maintaining consistent cleaning power throughout your home.
