Covid slayer breathing mask:
Since Amazon shipments have started, I started checking availability of uv lamps and water purifier cartridges.
Apparently the state of art has substantially advanced form the days of EPROM UV erasers.
I found a whole lot of cartridges. 11" UV lamp being the most common. Lamp brands being shipped are innumerable. Philips being one such. However the specs on Philips website are sparse.
I also found Osram - a well known brand - UV lamps.
WITH A CLAIM OF PRODUCING NO UV.
That certainly caught my eye. The company website had reasonable specs with substantially toned down marketing hype.
So I ordered a 4W 5" Osram lamp. It has a narrow wavelength spread centered at 254 nM, which is the RNA and DNA disrupting UVC wavelength of interest. Specs are attached.
I also ordered a water purifier UV replacement cartridge with a 11" Philips lamp. This will provide a ready housing and test setup. There were two variants from this supplier - light and heavy. I choose the light version weighing in at 250Gms. However expect the whole contraption to weigh around a Kg.
Note: This is not an endorsement for amazon or ionix. Buy whatever suits you.
Although literature is quite unambiguous on UVC ability to disrupt viri, How will one check for virus in the airstream flowing through this rig?
