The TPA 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 generates a high energy plasma field, which is very powerful in eliminating all ba-cte-ria and vir-us-es; It is different from HEPA in that mold/bac-teria are growing on filters but TPA eliminates all.
The TPA 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.
