The Airdog air purifier uses the state of art ionic wind technology that could filter the particles down to 14.6nm which is far beyond the 0.3microns that traditional HEPA could filter;
The high electrical field inside the Airdog generates a high energy plasma field, which is very powerful in killing all bacteria and viruses; It is different from HEPA in that mold/bacteria are growing on filters but Airdog kills all.
The Airdog uses non-consumable collecting plates, which you simplify wash it by hands or by dishwasher rather than spending money and changing filters all the time.
