Can UV-C deactivate COVID-19 without pre-cleaning?
UV-C is not intended to be a substitute for your standard cleaning procedure (vs. disinfecting) -- meaning wiping down dirt, food, grease, etc. from surfaces. UV-C cannot as effectively penetrate dirty surfaces, so standard cleaning beforehand is optimal.
R-Zero’s Arc is intended to dramatically improve current disinfection (manual disinfection or spraying) and offers reduced dwell time, no missed surfaces/human error, and faster room turnover, all with better disinfection efficacy. But again, it is not a substitute for your standard cleaning.
Harmful microorganisms exist in the air of indoor spaces where we live. As such, disinfecting the air is critical. UV-C addresses this; manual disinfection and electrostatic sprayers do not
