You Can Just Buy Far-UVC

Forget waiting for sci‑fi air magic: a $500 far‑UVC lamp just hit “add to cart,” promising to zap airborne bugs while leaving people untouched. The poster showed off their Thanksgiving centerpiece and four units at a dance—cue the comments turning into a UV rave. Some cheered the “finally!” moment, but others shouted “don’t stare at the sun indoors!” and the drama went off like a disco ball.

Safety became the main stage. joezydeco thundered that exposed light is “completely irresponsible,” while elil17 fired back that this specific 222‑nanometer wavelength—aka far‑UVC—doesn’t penetrate skin deeply and has solid animal studies behind it, though eyes are still a no‑go. One skeptic, juancn, dropped the nuclear take: “UV is carcinogenic—and making air too clean could mess with kids’ immune systems.” Cue hand‑wringing, jokes about sterilizing your turkey, and a chorus of “point it down, right?” confusion.

In short, the community is split between “shine the future on my living room” and “please don’t laser my eyeballs,” with lots of memes and a surprising amount of indoor rave energy.
