Philips NanoProtect HEPA Replacement Filter-800

The NanoProtect HEPA makes sure you are protected from viruses, bacteria, pollen, dust, PM2.5 and pet dander.  This filter was designed together with the device itself to ensure a perfect fit which guarantees the continuously smooth operation of the device.  NanoProtect HEPA filter’s low-resistance fibers maximize the airflow. The electrostatic charge attracts particles as small as 0.003 microns with 99.98% of efficiency, enabling the filter to clean the air faster than a medically used HEPA H13 filter (4).
