About this item BUIO IS THE NEW GREEN - HEPA filters have a life expectancy of less than one year. These filters are made of fiberglass, plastic, and other non-recycled material, which inevitably occupy a refuse heap for many many years. Boreas does not use HEPA filters to purify the air. With our breakthrough Negative-Ion technology, we use negatively charged air particles to purify the air, leaving the environment with natural oxygen UVC AIR SANITATION - We've ensured that the air around you will not just get pure, but it will also be safe thanks to our latest development in UVC sanitizing. Inside Boreas, there is a strong 260nm UVC lamp that sanitizes 99.99% of all air particles bigger than 2.5PM. We've sealed the device tight, to ensure that your eyes and skin will not be harm due to the UV light leak outside the air purifier.
