Ask HN: What happened to HVAC and open-air discussions for Covid?

3 pointschiefofgxbxl3 comments

Many months back there were mainstream discussions about HVAC solutions for Covid-19, such as purifying and sanitizing indoor air, or simply getting a lot of air flow through regions to reduce Covid risk. This was probably around fall in preparation for being indoors for the winter, but has anything happened since?

Has there been any significant progress for making indoor spaces safer by treating air? While spring and summer will alleviate some of the risk by having people outdoors more, there are still places like gyms, grocery stores, etc. that are indoors. I'm fully vaccinated, but the particular idea of going back to my weightlifting gym seems slightly risky to me, mostly from the thought of being indoors where people are heavily breathing (I'm not concerned about touching equipment... that can be sanitized and I can wash my hands).

These HVAC solutions are pretty expensive, and they require constant maintenance. Some businesses do install them, though, and I recommend https://www.santabarbarahvaccontractor.com/hvac-installation... if you decide it's worth the money. I have a pretty standard, although high-end, HVAC system without anti-Covid measures, and these guys helped me install it. They done their work perfectly, and the system is working beautifully in the summer.

I got back in the gym habit this winter, people wore and still wear masks. There was one possible exposure event, nothing came of it.

This is in a community that controlled community spread and proved it with testing and contact tracing so I was confident that very few people would go to the gym with the virus and the physical barriers and distance and now the vaccine are a reason not to fear.

What happened to putting copper tape on doorknobs? Effective antiviral measures abound that were deemed to much effort for what is, after all, a shared narrative experience.

I'm just glad that they were able to stop forcibly ventilating people. They never admitted a mistake, there; but they killed some people in a particularly nightmarish way with those.
