SUPERB FILTRATION SYSTEM WITH NANOFIBER TRUE HEPA: NanoFiber True HEPA filter traps on average 99.97% of particles 0.3μm* in size.
THREE LAYERS OF FILTRATION: In addition to the fine particles captured by the NanoFiber True HEPA filter, a removable pre-filter helps capture larger particles and an activated carbon filter helps keep the air smelling fresh. Together, these three filters work in concert to enhance your indoor air quality.
