Effectiveness of 222-nm ultraviolet light on disinfecting SARS-CoV-2 surface contamination

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has emerged as a serious threat to human health worldwide. Efficient disinfection of surfaces contaminated with SARS-CoV-2 may help prevent its spread. This study aimed to investigate the in vitro efficacy of 222-nm far-ultraviolet light(222 nm far uv lamp far uvc wavelength range light good choice for room disinfection) on the disinfection of SARS-CoV-2 surface contamination.

We investigated the titer of SARS-CoV-2 after UV irradiation (0.1mw/cm2) at 222 nm for 10-300 seconds using the 50% tissue culture infectious dose (TCID50). In addition, we used quantitative reverse transcription polymerase chain reaction to quantify SARS-CoV-2 RNA under the same conditions.

The results showed that 1 and 3 mJ/cm2 of 222-nm UVC irradiation (0.1mw/cm² for 10 and 30 seconds) resulted in 88.5 and 99.7% reduction of viable SARS-CoV-2 based on the TCID50 assay, respectively. In contrast, the copy number of SARS-CoV-2 RNA did not change after UVC irradiation even after a 5-minute irradiation.

This study shows the efficacy of 222-nm UVC irradiation against SARS-CoV-2 contamination in an in vitro experiment. Further evaluation of the safety and efficacy of 222-nm UVC irradiation in reducing the contamination of real-world surfaces and the potential transmission of SARS-CoV-2 is needed.

Sticking to the belief of 'Creating products of high quality and making friends with people from all over the world', we always put the interest of customers in the first place for 222nm UVC Germicidal Lamp UV Light Sterilizer UV-C Genuine Replacement Bulb for Air Purifiers. In the economic development strategy, our company strengthens the brand consciousness, enhances the market share, strengthens the propaganda strength, guides and promotes the consumption. Modern marketing emphasizes the customer and market as the center, and on this basis to establish a harmonious relationship with customers and society.
