UV-C light kills bacteria and viruses. This purifier has four speeds and can be set to run for different durations of 2, 4, 8, or 12 hours at a time. This 26 inch tower has a flashing blue
Ultraviolet (UV) light was first discovered in the mid-20th century, introducing a new way for people to eliminate viruses and bacteria. Although UV technology has risen to prominence in recent years, especially during the current COVID-19 pandemic, the majority of the general public does not fully understand exactly how UV lighting helps kill viruses and bacteria.

For these PS, blue light (400 to 480 nm) is more effective at a microbial inactivation than green (480 to 550 nm) or red (600 to 700 nm) light. The blue light of shorter wavelength (400 to 450 nm) is more phototoxic compared to that of the blue light’s longer wavelength. Although red light is not as effective as blue light, it can be more

We summarize studies investigating blue light or blue-red light for acne treatment in Table 2.[10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31] In general, high-intensity narrowband light (405–420 nm) applied for 8–20 min twice weekly for four weeks was reported to reduce inflammatory acne lesion count in the 60%–70%
A few months ago, we wrote about a mind-blowing bacteria-killing under-cabinet light, and it changed the cleaning game forever. And now, the brand behind this genius invention is introducing another incredible cleaning product: the Ellumi Recessed Retrofit Light, which gets rid of all kinds of nasties (think mold, fungi, and dangerous bacteria).

Of almost every pathogen we have ever studied, this virus is one of the easiest, by far, to kill with UV light. It takes a very low dose. This indicates that UV technology could be a really good 7suM3. 2 496 5 239 167 359 324 393 37
