Okay, true story about that sort of thing — On one ship assignment, one of the newbies fresh out of boot camp had the misfortune to have a last name of ‘Sample’. Needless to say, the poor kid was constantly being paged (‘piped’) to report here, there, everywhere over the 1MC (intercom system). After a couple of weeks, the XO unilaterally transferred him to Engineering, as he was sick of hearing ‘Seaman Sample, report to...’
Of course, although he was now ‘Fireman Sample’ in Engineering, we still had him running about looking for various items. Best one was when we sent him across the pier to a Navy ship to ask/get some ‘Fallopian Tubes’. Unbeknownst to us, the OOD (Officer of the Day) for the Navy ship was at the Quarterdeck when he arrived... and she was not terribly amused.

Viruses do not grow. They inject their DNA into a cell and use the cell to replicate more viruses. To "kill" the virus quickly, you need power levels of 20W, not the lower levels that you're talking about using.

Gingerbread Demon - OK link to crazy expensive light, and it wasn't 10 thousand dollars it was 15 thousand..... Who the * would pay that?
If the light machine that the Doc was trying to sell for $15k is the won on the wall in the video, there is no way that the guy in the video would be able to stand the UV colliding with his skin.
UV light is Ultra Violet, meaning we cannot see the UV-C UV light without special instruments as well as the Ozone protecting our eyes from most of the UV that comes from the Sun.

Most of the UV-C light masks that are for sale as kick-starters are not real. I haven't come across a single kick-starter for a UV-C mask that lists the type of UV-C light being used, which is critical because the UV-C light can be dangerous , if proper protection is not worn.
If the kick-starter doesn't describe what type of UV-C is being used, then most likely all you are buying is a really expensive mask with a fan and a model kit LED.

Nope, you are trying to compare a 20W light bulb to a 280nm UV-C LED which are very different.
280 nm UV-C LED is all that is needed to render the DNA and RNA of a virus inactive.
LEDs use much less energy than incandescent bulbs (20W) because diode light is much more efficient, power-wise, than filament light. LED bulbs use more than 75% less energy than incandescent lighting.

UV-C photons fall in the wavelength range from 200 to 280 nm (equivalent to an energy of 6.2 to 4.4 eV). UV-C LEDs emit UV light at selectable wavelengths between 255 and 280 nm. There is no other criterion that identifies UV-C other than the wavelength (or equivalently frequency or energy).
The linked article about the Kickstarter-funded mask specifies that UV-C LEDs are being used.
Someone beat you to it. That's life.

Provide a link to the exact wavelength of UV-C light that is being used in the mask.
None of those UV-C masks on the Internet can be taken as actually being UV-C masks. That's why I am building my own and publicly displaying the process and material being used.
Don't you think that if any of those UV-C masks that you see being advertised on the Internet actually worked or were real that the media would cover them exclusively as the number one measure to protect yourself against intake of SARS-CoV-2. I think so. But since not a single one of those UV-C masks have been featured on CNN, MSNBC, The Guardian UK, etc,. as being able to inactivate the SARS-CoV-2 virus during intake and exhaling of infected air and water droplets, then they are a scam.
Like I said most if not all of those Kickstarter masks are scams. Look at the comments regarding how pleased customers are with the UV-C mask. Most, if not all of the comments ,ask for a refund after the mask was not delivered on said date that it was supposed to be delivered. It's much cheaper for a scammer to create a 3D model and very fancy packaging for a mask and then claim production delays for what ever reason then it is to actually produce the mask.
Below is a link to an article about a recent court case where an Air Force veteran lied and said that he was a combat vet from the Marine Corps in an attempt to get money for a pandemic mask production program that provided zero masks.

UV light covers a wavelength spectrum from 100 to 380 nm and is subdivided into three regions by wavelength: UVA (320 to 400 nm), UVB (280 to 320 nm), and UVC (200 to 280 nm)

What is a LED?
LED
Light Emitting Diodes (LEDs) produce light when voltage is applied to negatively charged semiconductors, causing electrons to combine and create a unit of light (photon). In simpler terms, an LED is a chemical chip embedded in a plastic capsule.
Correction made to the UV-C LED wavelength at the beginning of the thread and subsequently thereafter, 285nm changed to 280nm.

Dude, you just appear to have insinuated that the Kick-starter funded UV mask is fraudulent (and all other such masks available online). Unless you can prove that, I suggest that you withdraw your statement. You know how litigious people can get in the US.
Sue me for what? If they are real masks that are UV-C masks I would have bought one by now.
The proof?
Read the comments section for each of those masks that you think are real.
https://www.kickstarter.com/project...-of-all-pathogens-and-air-pollutants/comments
Most of the comments entail no tracking order numbers being assigned to a shipment, so how is the customer supposed to be able to track their order?
More proof.
The fact that cloth masks are not 100% guaranteed to protect against a SARS-CoV-2 infection. A UV-C mask that is able to seal around the mouth and nose however should be selling like hotcakes and being supported and developed by the CDC, NIH and WHO organizations. So where are guarantees of quality on any of the UV-C masks being sold on the Internet?
Not to mention, the two other variants of Covid-19 that mixing in with the first variant of Covid-19 should make more people want to protect themselves with a UV-C mask that is guaranteed to dissolve the RNA/DNA of any Covid-19 variant that vaccines might not be able to protect against.
UV-C masks will protect against a Covid-19 + variant infection while being worn.
Cloth masks are not guaranteed to protect against any variant of Covid-19.
Vaccines for Covid-19 are lagging behind.
So in all respects there should have been an FDA approved and CDC/NIH supported UV-C mask out months ago.
Therefore the UV-C masks on the internet are not real UV-C masks.
How can someone selling a fake UV-C mask expect their claims in court to standup, considering the all of the comments asking for refunds due to no tracking order, orders being late by three months or more, etc.
Besides, I was already scammed out of money for an N-95 mask that I had purchased close to a year ago when the pandemic first broke out. I'm certain that the UV-C masks being offered on the Internet are nothing more than elaborate scams using flashy pamphlets and brochures to sell their scam with.
Look at Amazon, how many UV-C pandemic masks do you see being sold?

Oh well, I doubt any of the manufacturers will know not care what you write about them here. I'm not affiliated with any of them in any way BTW.
Are you going to get your mask FFP2 certified?
Are you going to get your mask FFP2 certified?
Not for my personal use. I don't have any reason to get it certified because I didn't create the mask, therefore I can't upgrade it, certify it and then re-sell the mask.
I can only upgrade the mask and hope that other people purchase the same mask and upgrade theirs as well.
'Smart' face masks promise high-tech protection - BBC News
BBC review of various high-tech masks - the UV-C one looks more than slightly ungainly and I would probably choose to use a lower tech version, especially as I've had my first vaccination against Covid-19.

To be honest I wouldn't rest my laurels on the vaccine alone.
I recently purchased a new double cloth mask with with copper ions woven into the Polyester pieces.
Is it possible that an automatic transfer of some of the 280nm photons created by the UV-C Less will take place across the copper ions?
If the 280nm photons transfer across the copper fibers normally then a possible energy grid can be created to further trap and inactivate SARS-CoV-2.
Sorry to disappoint but the first ionisation energy of copper is 7.726 eV. Thus a UV-C photon does not have enough energy to remove the single 4s orbital outer electron and create a Cu+ ion. UV-C photons mainly just reflect off copper.
Neutral copper is effective at disrupting bacteria and viruses. Cu2+ ions are even more effective but the second ionisation energy of copper is 20.29 eV to remove a first 3d orbital electron.
The combination of Cu2+ ions and UV-C is used in water treatment to kill pathogens so it's a sound idea but I don't know how well it would work in a mask.

Impractical - that's probably the best way to say it...
The basic fact is that by the time any R&D work is done on this, there would likely be little need for it. Just wearing a pair of good quality conventional masks does the job quite adequately.

The UV-C mask shown in the BBC video looks like a right pain to wear.
But at least the UV-C 280nm photons will reflect off of the copper, thus creating a random pattern of 285nm photons being reflected in the mask. Similar to suppressing fire one might say.
I though about using the Copper Cloth Mask as a first wrap around the plastic air intake of the N90 respirator.
COVID-19 is caused by infection with a new coronavirus (called SARS-CoV-2) and flu is caused by infection with influenza viruses.
Covid-19 is not a flu.
Between October 1, 2020, and February 20, 2021, FluSurv-Net sites in 14 states reported 183 laboratory confirmed influenza hospitalizations for an overall cumulative hospitalization rate of 0.6 per 100,000 population. This is much lower than average for this point in the season and lower than rates for any season since routine data collection began in 2005, including the low severity 2011-12 season.
Based on NCHS mortality surveillance data available on February 25, 2021, 19.3% of the deaths that occurred during the week ending February 20, 2021 (week 7), were due to pneumonia, influenza, and COVID-19 (PIC). This percentage is above the epidemic threshold of 7.2% for week 7. Among the 3,972 PIC deaths reported for this week (week 7), 3,130 had COVID-19 listed as an underlying or contributing cause of death on the death certificate and four listed influenza, indicating that the current increase in PIC mortality is due primarily to COVID-19 and not influenza.
Covid-19 might be obsoleting the seasonal flu viruses. If Covid-19 wasn't more powerful than Flu, then hospitals would be reporting the same number of Flu infections and deaths that occur due to Flu that would fit in with consistently seasonal reports. Since Covid-19 hasn't stopped and doesn't appear to be stopping, the some of all fears has to be discussed. The sum could be that Covid-19 is the new seasonal virus that will replace Flu with periods of infection lasting up to two to three years that then suddenly sees the end of Covid-19 infections. With people being vaccinated against Covid-19, there is a good chance that Seasonal Flu might be eradicated only to be replaced by Covid-19. Such a theory cannot be proven until the Covid-19 pandemic ends and Seasonal Flu returns.
If Seasonal Flu does return after the Covid-19 pandemic and maintains a normal seasonal infection and death rate then we can be assured that the Flu is only dominant when Covid-19 is not present and that the Covid-19 vaccination does not protect against the Flu.
If Seasonal Flu does not return after the Covid-19 pandemic and very few cases of Seasonal Flu, under the normal seasonal consistencies, then the vaccination against Covid-19 has in part helped reduce Flu infections and deaths.
But if we start seeing double the numbers of Seasonal Flu and deaths related to Flu after the Covid-19 ends, and the uptick in infections and deaths related to Seasonal Flu remains consistent then the pandemic has actually enhanced the Flu virus. Which could then be followed by a sudden decrease in Seasonal Flu with the re-emergence of a stronger and even more deadly variant of SARS-CoV-2.
We could even see other viruses suddenly emerge that would throw us off step again in combating Covid-19.
The variables are almost uncountable.
But like I stated, we won't know for certain how Covid-19 has effected Flu and we can only wait until the pandemic ends to see how the first Seasonal Flu goes after Covid-19 ends. What ever may happen after the Covid-19 pandemic ends, could be much worse then it is now, nominal and would follow yearly seasonal trends, or less worse only to be followed by an extreme uptick in new cases of Covid-19 or Colds and sinus infections that are ten worse than usual.
Back in December of 2020, I got hit with something twice. The first time had me down for a week, wasn't Covid-19. Flu A or B. Then I was fine for about a week and half and then got hit again. The second time was worse than the first by about 5 times. The second test didn't show any Covid-19 or Flu's. Either really bad sinus infections or colds.
Regardless, since the only known cure for SARS-CoV-2 is inactivating it with UV-C light, my only suggestion is get with the program and upgrade your plastic respirators or other fancy looking face plug with 280nm UV-C LED's.
