By using both a HEPA filter (High Efficiency Particulate Air filter) and their new electrolyzed water technology to purify the air, Sanyo believes the Air Washer Plus will remove 99.97% of airborne particles and allergens and will also remove odors from the air.
The HEPA filter is basically a mat of minuscule fibers, which filter out the majority of particles in the air. It executes this by randomly arranging small fibers; the air flow then helps to move the particles to stick to these fibers on their way through the filter. HEPA filters are used in many airplanes to filter the air and even in clean rooms, such as those in critical wards of hospitals.
By combining tap water with electricity the Air Washer Plus creates electrolyzed water, this electrolyzed water produces two types of active oxygen that are thought to purify the air.
The Air Washer Plus then cleanses the air without the need for any chemicals due to its combination of electrolyzed water technology and HEPA filters. The system also uses a 3 directional air system; it outputs air straight up, to the left and to the right. This is to aid air circulation within a room, making sure all the air of the room goes through the system. The system can be moved to other rooms around the house, allowing your entire home to share clean air.
Due to heavy usage of a HEPA filter, the Air Washer Plus will require this filter to be changed at times. It has a filter indicator to let you know when this needs to be done. So after an easy change of its filter, you can go back to breathing clean air.
