Replacement filter for the Micro-Ecology Air Purifier

We have all seen Plasma tube, UV light and Hydrogen Peroxide machines that claim to kill bacteria and Virus, but how do we know?  None of these units, as far as we know, uses proven and visible Hepa Filters and Activated Carbon Filters, and therefore cannot remove particulates, pollen, dust, dander etc. Ravair's filters are proven to work- just take a look at the before and after images yourself! Please note the image of the filter is from a Wall-Mounted Unit- the effect will be similar using this unit.
