Three-Stage Filtration Process

The first stage of the GermGuardian’s filtration process takes place even before it enters into the main filtration system. Its pre-filter screen weeds out the larger airborne particles such as dust, pet hair, and pollen.

Secondly, the air entering the filter goes into the True HEPA filter where the filter captures most of the particles such as plant pollen, mold spores etc., in sizes described earlier.

Finally, it goes into the last stage which entails treatment with the UV-C light technology in combination with the Titanium Dioxide. The result is a purified air which has been cleared of harmful molecules.
