Just another gimmick. I can understand, maybe, in hospitals where there are lots of different kinds of things, but not in homes. Virus and even bacteria only last a few hours, even under the best conditions.

Simple bleach and water is likely just as effective in my opinion.

Only UV-C does any real damage to something like a virus -- and UV-C never makes it to the Earth's surface -- regardless of Solar Minimum/Maximum garbage. So, I don't see why you are trying to tie Solar Minimums to pandemics. That just doesn't make scientific sense.

If Covid is mostly gone in a year, it will be because we vaccinated and took other measures to eradicate it. Not because of a Solar "event" or period.

The thing is, as far as I know, uv/blacklight wavelengths/radiation is in that spectrum. It may kill virus/germs and it may not.

For sake of argument, let's say it does.

If so, it seems to me that light in a specific wavelength is the same no matter the type of bulb that produces it. If that's true, it seems ANY bulb that makes it is as good as another.

The world is full of people and companies that will say ANYTHING to make a dollar.

I say PROVE one bulb is different from another and that the claim of the expensive one is true. A bunch of "testimonials" from "doctors" I've never heard of (also known as paid actors in a white coat) or advertising lingo or a fancy package doesn't convince me. I quit believing in "magic" and "special powers" when I was about 10.

Our sewer plant does have a UV light system - Before it goes to that light bank it goes through a 22 million dollar plant.

If it was easy as just having UV lights - we would have saved tons. The engineers instead are telling us to spend more than $40,000.

can I answer as if I were NE?

AllyM: Ok, I'll tell you exactly that. Studies so far show that UV-A and UV-B do NOT kill Covid-19. Only UV-C does. That's kinda the whole point here that I'm making. What you are saying does not make sense as far as Solar Minimum/Maximum -- the sun is not killing Covid.

This was in NY pOst and a few other sources.

While most cases of COVID-19 are contracted from airborne particles via person-to-person contact, the study found that the "midday sunlight in most U.S. and world cities during summer" can break down the virus in a way it can't during winter months, with UV rays deactivating coronavirus faster than it does most strains of the flu.

Yes, and I also totally remember when T was saying last April or so that this would all go away when it warmed up in the summer because of that light exposure. That clearly didn't work out.

Again, the studies that have been done show that UV-C can kill Covid-19, but that UV-C does not make it through our atmosphere.

After a bunch of searching, I finally found the actual study. It mainly concentrates on "artificial UV-C" exposure. It does then go on to see how UV-B might help and does conclude that it can help.

However, that same study goes on to talk about average UV-B rates from the sun -- which do NOT change significantly between "Solar Minimum" and "Solar Maximum" periods from what I can find anywhere. Therefore, again, your whole point of trying to relate this to specific time period where there is a "Solar Minimum" that leads to more pandemic is flawed. It simply isn't accurate.

Again, even if UV-B does have some effect on the virus -- which it appears it accurate -- it does NOT at all confirm your odd statement that this relates to "Solar Minimums" or solar flares.

Once again, as I've said several times, you seem to find a tiny piece of truth in something and then run with it to a conclusion that just doesn't follow.

"My area has cryptosporidium a bacterial cyst"

Allym you are sadly misinformed. Who told you it is a bacteria? Cryptosporidium is a microscopic parasite that causes the diarrheal disease cryptosporidiosis. NOT a bacteria. It is a critter.

That's why we carry small portable water filters when camping in the backcountry. Effective and much less complicated than trying to hack together an expensive lighting treatment solution.

Also Ozone is an off product of UV-C. Can't be in the same room with it. Amazon sells lamps for $100 on timers.

Problem is that it will fade towels and make elastic brittle and non-restrictive. There are other issues too I'm sure. Can't just run it everywhere in the house.

They also make little UV-C boxes so you can sterilize your phone, etc.
