How can a single technology do both? Sounds like a stroke of genius, and in a way, it is.
Based on a technology pioneered by Albert Einstein himself, and a integral technology included in the Intellipure Breathe Wright Premium+Plus system, which has been claimed, "The best indoor air treatment system available today".
Ever notice how clean and fresh the air is around the mountains, waterfalls and ocean waves. This is the cleansing, purifying effect produced by high natural levels of both positive and negative ions. The process, Dual BiPolar (DBP) ionization, delivers ionized oxygen molecules (NOT OZONE) into the air space that can neutralize many volatile organic chemical compounds (VOCs), sterilize and molecularly destroy mold, mycotoxins, viruses and bacteria. They then attach themselves to airborne particulate pollutants such as dust, pollen and smoke, causing them to agglomerate together allowing the DFS filtration to capture even more effectively. Similar to how positive and negative ions surround particles, they are also attracted to pathogens. When the ions combine on the surface of a pathogen, they rob the pathogen of the hydrogen necessary for them to survive. Up to 99.99% of all airborne pollutants are reduced from breathable air when our system is at work, even those breathable contaminants as small as .007 microns.
