HEPA filters capture 99.97% of particles (including attached pathogens) and physically remove pollutants. UV-C inactivates microorganisms but does not remove particles. Best approach: HEPA capture + UV-C inactivation. HEPA is better for allergies/particles; UV-C supplements germicidal action.

They effectively inactivate airborne viruses, bacteria, and mold. However, in portable devices, air exposure time is short, limiting effectiveness. Integration into HVAC systems or upper-room UVGI is more reliable for reducing airborne pathogens. The EPA recommends combining with HEPA filtration; it is not a standalone solution.

Hospitals, offices, schools, homes, elevators, and other indoor spaces. Continuous low-dose operation yields the best results.

UVC light destroys the nucleic acid structure of suspended microorganisms. Combined with fan circulation, it achieves dynamic purification with inactivation rates over 99.9%.

A UVC air purifier uses 270-280 nm UVC LEDs to inactivate airborne microorganisms. Commonly integrated into purifiers or air conditioners. By circulating air and exposing it to UVC, it reduces the spread of viruses and bacteria. Suitable for hospitals and offices but requires enclosed designs to avoid human exposure.

Yes. Often integrated into air conditioners, air purifiers, upper-room air sterilizers, or standalone circulation devices to inactivate viruses, bacteria, and mold in the air.
