Someone made an interesting point that we got rid of cholera by drinking cleaner water and that we'll get rid of Covid by breathing cleaner air.

Fish tank filters are practically required for fish. I don't see why home air filters (HEPA) aren't more common especially in extreme environments with window opening not realistic.

You can build your own high-flow HEPA filter for about $45: 1x 20-inch box fan ($20) 1x 20x20 MERV-13+ MPR-2400+ HVAC air filter ($20) 1x roll of duct tape ($2.50) Air particle meters and other testing show they work just as well as big expensive machines (it's just the filter doing all the work). This is indeed a dirt cheap way to improve overall health.

That homemade air filter will, however, be much louder than a newer Swedish blue air.

Obviously. So what would’ve happened if we had created a zillion jobs installing air filtration to create healthier workplaces across many dimensions (not just Covid) instead of paying people to stay home?

Do you have a time machine to bring this bit of information back in time? And, would anyone have believed you? Many things are obvious in hindsight.

Why didn't they research this earlier? "oops, we forgot?" Or "oops, nobody thought about it?" There have been videos going around many months ago of people in the business saying this is what should be doing instead of wearing masks. But hey, let's not doubt or question, that's bad!

Wouldn’t be a bad idea to start having air filters in confined spaces. Elevators, gyms, restaurants. Not saying it has to happen all at once, but it would help decrease most respiratory diseases from spreading.

The Chinese have a head start on this since they’ve been outfitting indoor spaces with HEPA filtered air because of air pollution problems.

So who makes a good room air filter? I have a dozen container ships go by, a few hundred meters away from my window a day.

A heavy duty Blue Air? I’d stay away from the 605 unless your problem is really bad, they are just too loud. The newer ones are nice and quiet, though the ones they target at the western markets are much so than the ones that sell well in China (where air pollution is much more of a problem). You might want to start with measuring your indoor air quality.

I bought a air filter which takes a rectangular panel filter like a Filtrete FAP series. Then I replace the filter regularly by cutting HEPA panel filters sold at Walmart to size. It's a cheap way to keep air clean at home. The amount of gunk and black soot and dust stuck within and to the filters is amazing. I also tend to run the device at full speed, the noise helps me tune out disturbances and leads to peaceful sleep.

Maybe this is pure science fiction but it would be amazing to see Covid alarms, if the virus was detected in the air.

Earlier quoted context omitted.

> Have you lived any length of time in Canada? Yes, I am a Canadian. I lived there for 25 years. I have Canadian citizenship. Most of my family still lives there. I also ended up stuck in Ontario for most of COVID. I have family in Ontario, in Quebec, and elsewhere in the country. I don't think Ontario had a very good handle on COVID. It's also no secret that Canada is suffering a major staffing, and funding shortage…

The masks might have been after seeing a different comment, sorry. The problem with improving the system is that 1/3 of the country seems to want the US system in healthcare and probably (lots?) of other things. So it goes. Re: Ontario, I was looking at Ottawa specifically, the province generally and while it's "blessed" with a Conservative premier he's taken more medical advice (or indulged his populist leanings) mo…

I'm not really sure what you're trying to say here. I don't really think there's any real reason to think that 1/3 of Canada wants the American system. That's certainly never something I've seen any evidence for. My impression was always that it was a point of general pride that the Canadian system "wasn't' like the American's". Only a small fringe want otherwise from what I can tell. It's not even in the platform of any small fringe parties as far as I can tell. I would suspect if a niche issue like Albertan separatism finds political expression, this would too.

Could you be conflating talks about "privatization" (allowing private clinics to exist and take OHIP) with private healthcare payments (you don't get OHIP) by mistake? Those two are not really the same at all, but get conflated in the media often.

That last part there about Ottawa or Ontario, not sure which one, doesn't really make much sense, sorry. It's unclear what you're getting at. Nothing there really sounds related to what I'm talking about.

Fish tank filters are vital to the nitrogen cycle but your point still stands.

Considering you’re exposed to water during limited times (and need to actually ingest it) but exposed to air 24/7 (or else you die) that doesn’t seem like a reasonable comparison.

If someone standing in front of you sneezes, a filter in the HVAC isn’t doing anything to stop you from getting covid.

I mean, isn’t airborne transmission still uncertain for Covid?
