Bionaire's LC1060 combines an ionizer with powerful fans to help purify the air in your bedroom, living room, or office. It's designed to be mounted directly in a window, saving you floor space and providing easy access. The HEPA filter can remove up to 99.97% of airborne particles. It's assisted in this process by an ionizer that traps particles and draws them back into the filter for purification. A five-stage filtration system ensures that your space is free of harmful particles.
