Read the primary article or dive into the live Hacker News thread when you're ready.
if you do use a filter make sure it captures metal vapor, which is unlikely with a regular hepa filter.
Laser cutting or engraving makes even worse fumes and requires seriously good filtering. I personally think they're nasty enough that it is irresponsible to just dump this stuff outside into the environment without cleanup but it's certainly better than breathing it.
Seeing as a lot of solder is lead based i imagine this would be a huge safety concern if it did create lead vapor.
I host movie nights with friends and sometimes someone might even smoke in the room, air purifier clears the air quite fast and there absolutely are no odors left. So yeah you can and if you solder or 3d print often, I'd suggest to get one, they don't cost much.
I'm not allergic and air here is basically always perfect - 1-5 ppm, but I still love it. It does filter out allergens and people allergic to pets find it easier to breathe (I have a dog). It also lowers amount of dust a bit, and I have an automation to run it on full speed when robot vacuums floors, I think it might help filter some stuff out.
I wish there'd be a way to put activated carbon packs inside somehow, because I'd love to change it more often than the full filter.

isn't that the case with all of Dyson's 'bladeless' fans?
but a bunch of years ago there was some blameless fan which worked somehow else (electric charges or similar???) and had the side effect of them emitting ozon
this is why if you google dyson+ozon you will find a lot of articles telling you in various details "no they don't produce ozone", because at least some dyson like fans did produce some amount of ozone in the past. Idk. if that also applied to some old dyson products.
The Dysons do have regular bladed impellers in the base, but by expelling the air in a ring shape take advantage of viscosity to pull air around the ring for an added flow.
My main reason for preferring the Dyson type fan is the noise they make is a soothing white noise, instead of the helicopter-like beating noise the box fans make.
My Vornado runs 24x7 and on minimal setting is inaudible, on second setting is very quiet. And it costs way less than a Dyson!
I have two units in the house, and when I ordered second unit I got a defective one - probably fan was not balanced. It was making noise like normal fan. I exchanged it on Amazon, and boom - second quiet fan in the house.

It's a public health imperative that various kinds of air cleaning be deployed universally in public places to combat COVID-19, particularly in classrooms. It's insane that the denial is so deep.
When sleeping with window and door closed and just by myself, co2 levels exceeded 2,000ppm by morning and only fell once I was awake and opening doors.
With the window slightly open and the door slightly open, levels were at a much better 700ppm or so.
If this thing works as advertised, that would be great. There are a lot of situations where it’s difficult to sleep with the window or the door open.
But still, the note at the beginning of this one struck me. I'm not sure we need a warning on _every_ single article. If the warning served to keep the snarky comments away, great. But this is the internet. People are gonna snark anyway, so the caveat up front doesn't accomplish what one might hope it would.
This sentence made it hard for me to give much consideration to the rest of the review, as I seem to have different standards - 30C is 86F and I'll have defenestrated myself before my office reaches that ambient temp.
Search Amazon for “COWAY Air Purifier for Home Bedroom, 2-in-1 with Fan”
Airfanta's 4Lite is touted as having laminar flow specifically for health reasons: https://air-fanta.com/products/airfanta-4lite

Could never find the right surface to put it on, the weird positioning meant either air points up or down - no in-between preference.
Lastly, the most annoying, the amount of dust that would be persistent on the large center pad area, so I always felt like it was just blowing old dust on me.
I dropped mine off at a donation site. Hopefully someone finds joy in it.
Ended up buying one of their air circulators too, which has only 4 speeds, but is amazing at pushing the air out the window when my poor UK house is hotter than outside. Downside is it uses the same ir remote, so you have to math out how to get to the speeds you want as the plus & minus speed buttons loop around. (Or ask google for the speeds directly).
Height of the heat wave it was lovely to say to Google "I'm boiling" and it would go into my built routine, turning both up high and oscillating for a bit, then calming down automatically after 5 mins, and then slowly reducing more over time.
