Optical filter lens, bandpass filter, customized UV Filter glasses ,Low Transmission UVC 222nm 230nm Deep UV Bandpass Filter
Type: 222nm bandpass filter
Size: 108mm×66.5mm×1mm
Center wavelength: 222nm
Material: Quartz Glass
FWHM: 12±2nm
Surface quality: 80-50 scratch-dig
Dimensional tolerance: +0/-0.5mm
Center wavelength tolerance: ±2nm
Minimum peak transmittance: 70%
Temperature range: -50 to 120°C
Moisture resistance: per MIL-STD-810E, method 507.3
1. Only Passable wavelength 210-230nm only(refer to the picture below with the filter)
2. Safe for prople, Filter out longer wavelengths that are harmful to the human body.
3. Custimzed SIze and shape; such as round, rectangular, and square to integrate into various bulb configurations.
222nm Far UVC Light you may need:
222nm Far UVC Lamp with Remote Control
Far UVC 222nm Tube and Module Kit
Portable 222nm Disinfection Box

It is a UV bandpass filter, only pass the UV near 222nm wavelength uv, which has a very high transmittance at 222nm and can block the longer wavelengths of 240nm 256nm and 280nm.
Studies have shown that for sterilization, UVC sterilization from 200 nm to 280 nm is the most effective. However, certain ultraviolet radiation can cause damage to human skin. But 222nm can sterilize without causing damage to the skin.
By installing a 222nm uv filter, the uv lamp can transmit the required ultraviolet frequency while blocking harmful wavelengths.
Conclusion: The emission of the excimer lamp at 222 nm can be sterilized without penetrating the basal layer of the skin. But the emission spectrum must be filtered to prevent harm to people by blocking the longer dangerous wavelengths.
PLease see the comparison picture of with filters and without filters：
UV light at 222 nm is capable of sterilization without harming human skin, making it a safe and effective technology to combat bacteria and viruses, including COVID-19. Here is a article from NCBI that indicate 222nm is safe for people:
