Frequently Asked Questions

How effective is UV-C light compared to HEPA filtration? UV-C light and HEPA filtration target different types of pollutants. HEPA filters capture particles mechanically, removing 99.97% of particles 0.3 microns and larger. UV-C light inactivates biological contaminants like bacteria and viruses, plus mold spores by damaging their DNA. The most effective systems combine both technologies to address the full spectrum of indoor air pollutants.

Do UV-C air purifiers produce ozone? Properly designed UV-C air purifiers operating at 254nm wavelength produce negligible ozone. However, some UV systems operating at different wavelengths or using "activated oxygen" technology do generate ozone. Check specifications and look for units certified as ozone-free if this is a concern for your household.

How often do UV-C bulbs need replacement? Traditional UV-C bulbs typically require replacement every 12-18 months as their output gradually decreases. UV-C LED systems last significantly longer, often 3-5 years, and maintain more consistent output over their lifespan. Factor these replacement costs and maintenance requirements into your purchasing decision.

Can UV-C + HEPA purifiers remove all types of indoor air pollution? No single technology removes all pollutants. UV-C + HEPA systems excel at particles and biological contaminants but have limited effectiveness against chemical vapors and odors. For complete coverage, look for systems that also include activated carbon filtration or other technologies specifically designed for chemical absorption.

What room size requires UV-C + HEPA purification? Room size isn't the determining factor for needing advanced purification. Consider pollutant sources, occupant sensitivities, and air quality goals.
