Yes brother, like how they make you wear a seatbelt. Next they'll have us all in camps.

I’ve bought the Coway AP-1512AH which filters air, and is extremely silent, and I have a separate CO2-PM10-PM2.5 measurer. It does wonders against asthma. PMs go from 25microgram/m3 to 1 in half an hour, which I trust because the measurement tool is separate. I never succeeded to have less than 10 before the Coway. Before that, I would sneeze first thing in the morning, then sneeze by rows of 10 times in Spring, 30 t…

Can I ask why you chose this brand and this model? I’m looking for an air filter but have no idea which brands to trust.

Wirecutter recommends Coway

I suggested this as an alternative to mask enforcement months ago and was ridiculed on hacker news. I'm happy to see the idea come up again as it has a lot of solid science behind it.

It's still ridiculous because it's incredibly expensive compared to just wearing masks.

Curious to know how to wear a mask while eating.

Yes, health authorities can be wrong, but if you want to prevent, stop, or aliemoriate a pandemic, you need cooperation. You can't just have Joe Sixpack decided to not quarantine himself or not wear masks. Yes, the authority figures can be wrong. Fauci can be wrong. People can die when health authorities make mistakes, whether through indecision or decision. I myself keep wearing masks after the CDC says I don't need…

On the other hand, once a building is done right you don't have to worry about it again (other than replacing filters and the like on schedule), while masks are too easy to wear wrong, lose, or take off (particularly when eating)

I feel it is punching down to attribute not wanting to quarantine or wear masks to a 'Joe Sixpack' caricature. The ultra-wealthy and powerful didn't want to quarantine or wear masks either - except they had the luxury of boarding a private plane and fleeing the country, or sailing around on a yacht, etc.

For a while, YouTube and friends were banning people who pointed out the WHO was wrong. So, probably quite a few people.

that was specifically about calling Covid a hoax. Those who were fighting against this censorship weren’t fighting for Covid being airborne or not

My recollection was that they banned disagreeing with the WHO[0]. The examples given in that article are fair enough for banning, but they banned scientists who were not quite so crazy[1]. Anyway, that’s based on my memory (which is often faulty), but those links seem to corroborate it.

I've been reading stuff like this for some time now, I actually had our ventilation redone, albeit for non-Covid reasons because we had too much dust due to leaky vents causing asthma issues and it makes things a lot better even without worrying about Covid. I never could find any easy/good way to add UV to the mix without having to redo everything again, though. I wonder if anyone knows any easy/simple add-ons like…

I actually got one of those for the bedroom after reading someone mentioning it during another HN thread. It does seem to make the bedroom better, though I don't think it's quite enough for the whole house.

I don't have any measuring devices to see the impact directly, though.

I would love to find a portable air exchanger too—opening windows helps with CO2 levels but it’s inefficient for most of the year in much of the United States. Built-in air exchangers with heat recovery are available but are a non-starter for anyone in a rented place. Unfortunately, no good solution exists so far

Yeah, I live in a place where, well, let's just say that opening the window for much of the year simply isn't done. I don't think some of my windows will even can be opened any longer due to having been closed for so many years.
