A study has determined that intermittent low-intensity far-UVC light can inhibit mould growth below the threshold limit value of 23 mJ/cm2.
At 222nm, far-UVC light was shown to prevent development of common mould-producing fungi, specifically Penicillium candidum.
The on-off duty cycle pattern of the far-UVC light used in the study is “consistent with its use in real-world settings”, the corresponding paper stated.
