Panasonic Nanoe F-PXJ30AHD 230V Air Purifier (Grey) Product description Applicable area=215ftsquare, Composite Filter Life= 2yrs,Deodorization Filter Life=2 yrs, Odour Sensor, 3D Circulation Airflow, Noise[Db{A}] High-Medium-Low 				    	 					 From the Manufacturer     How nanoe Work? nanoe possesses the characteristics of removing hydrogen from viruses, bacteria, odours and allergens. Effectiveness of virus removel depends on the number of OH radican. With nanoew device that generates at a high rate of 480 billion per second, the higher the effectiveness of the anti-vital power.     What is nanoe ? A nanoe is a fine (5 to 20nm) and weak acidic water particle with a reactive substance and an electric charge.     Characteristic Of nanoe: Long Life 6 times longer lifespan than normal ion nanoe has a lifespan of 6 times longer than normal ion and it contains moisture around 1,000 times to minus ions.     Characteristic Of nanoe: Microscopic Scale One-billionth of the volume size of a steam particle nanoeTM is much smaller than steam that can deeply penetrate into cloth fabrics to restrain dirt.      Characteristic Of nanoe: Water-originated 6 times longer lifespan than normal ion nanoeTM is comes from condensed moisture in the air. Water replenishmentfor the appliance is not required.     3D Circulation Airflow Usually, various types of pollutants appear at different areas between the ceiling and the floor in the room. In response, the 3D circulation airflow is divided into two modes —"Side Airflow' and "Front Airflow" to remove pollutants     Composite Air Filter Composite Air Filter The Composite Air Filter consists of 3 types of technology: Super Alleru-buster, Green Tea Catechin and Antibacteria Enzyme. It inhibits 17 kinds of virus, bacteria and allergens up to 99%.
