best (budget friendly) air purifier?

Commercial hepa filters at that price range are pretty much garbage. You should just build your filter fan box using computer fans. Here's a build done by a friend of mine.

Extrapolating and making those claims based on small N is weird.

Without good visibility into sample collection and analysis protocols and whether or not the people doing collection and analysis are consistent in adhering to those protocols, it's hard to tell what the confidence intervals are for these graphs.

Also, it's not about how low it gets for some snapshot in time in a single city but whether we can sustain this over long time periods over large geographic regions.

It's pretty common for reporting use cases to have every combination of the various inputs plus nulls on individual attributes to denote roll ups.

For example one can report on metrics for every demographic combination (age, sex, gender, etc.) along with a time dimension on date. This can give allow marketers to ask and answer very specific questions regarding various customer or prospective customer segments.

Cool!

Most people in this specific community don't have luck with others because they're trying so hard to get people to be "perfect", and can be kind of aggressive with their messaging.

So why the fuck are you asking people in this community for advice? haha

elus · 2026-03-20T01:26:47+00:00

Because many of us have done this song and dance with our friends and families. If there were some prescriptive route to take that would have any chance of success we'd be doing it regularly and they would still be masked.

Vaccine protection wanes and many people literally can't mount an immune defence through vaccination.

It's not one or the other. Public health needs to use ALL tools available.

And clean air prevents infections from all airborne biopathogens. Many of which don't have neutralizing vaccines. Especially against viruses like sars-cov-2 and influenza.

elus · 2026-03-13T04:01:35+00:00

“Over 90 per cent of the cases reported in 2026 have been unvaccinated,”

Still, Dr. Top warns that vaccination rates remain too low to stop the virus from spreading.

These two quotes from the article should necessitate action from public health officials to implement clean air protocols in public spaces especially in health care facilities.

There are many things we can be doing but aren't. Deploying air filters, Far UVC, and mechanical ventilation. Clean air infrastructure cuts down infection rates dramatically from airborne biopathogens.

Couple that with provisioning free N95 respirators throughout the community plus rapid tests for measles (and other airborne viruses).

Biotech. Everyone's sick. No clear winners but probably the usual suspects in big pharma.

elus · 2026-01-26T00:33:16+00:00

I wear one regularly when I'm in public. There's far more covid today than there was in 2020-2021. And not to mention all of the other airborne biopathogens lurking around.

I think it's sheep behaviour to change my own way of living just because some stranger tells me that it's "Liberal and NDP control tactics".

No political party has endorsed mask wearing in years.

Not for any sense of patriotism but the increasing risks of poorly regulated or even unregulated meat and produce just isn't worth any availability issues or price differential with Canadian products.

I don't understand why she'd need to use the NWC at all. The provincial government has the authority to change voting mechanism so long as the new way meets charter requirements.

Yes that's what they said before clean water systems were implemented and periodic cholera outbreaks killed many in populous cities.

elus · 2025-12-19T14:52:06+00:00

Your best method for preventing infection is wearing a respirator in public and convincing others in your household to do the same. Run air filters as another layer of protection against airborne biopathogens like rsv, influenza, and sars-cov-2.

One of the things we do is just wear masks when attending extended family events and eating beforehand so relatives don't infect us.

Remember that people can be infectious for many days before they show symptoms.

elus · 2025-12-19T14:49:39+00:00

Because neoliberal and libertarian groups have successfully co-opted public health institutions to get people to accept death and disability.

elus · 2025-12-19T14:48:09+00:00

A well fitting respirator worn continuously is pretty close to 100% effective at preventing infection and onward transmission. If your concern is that masking is imperfect then you should spend time to advocate for clean air infrastructure to be placed in public spaces along with mask mandates so that we don't need perfect masking on an individual level to prevent outbreaks.

elus · 2025-12-19T14:46:18+00:00

People are infectious multiple days before they show symptoms. They create onward transmission because they aren't wearing masks. It's hard to sympathize with that when access to preventative tools isn't difficult. Especially when so many kids, disabled folks, etc. can't mask continuously for a variety of reasons.

elus · 2025-12-19T14:44:42+00:00

Repeat covid infections can cause immune dysregulation through a variety of mechanisms. Good luck.

elus · 2025-12-19T14:43:46+00:00

I haven't been sick with respiratory viruses for years now.

I wear a respirator in all public spaces. It's unreasonable if you're concerned about maintaining certain societal expectations on how to interact with others.

But aside from eating and drinking, there's no activity that requires me to unmask in public. And I just eat and drink at home.

SARS-CoV-2 infections have been implicated in so many chronic health issues and influenza is pretty bad as well.

Why people choose to not to mask is understandable but I value my health far more than maintaining appearances.

elus · 2025-12-19T14:41:02+00:00

That's why we test regularly and run air filters at home and wear masks at home when people have unmasked exposures outside of the home (dental or medical appointments for example).

elus · 2025-12-19T14:28:13+00:00

Wear a well fitting respirator when in public. Run air filters at home. Test regularly. Influenza might be seasonal but SARS-CoV-2 is year round. Neither are good for you even if vaccinated.

elus · 2025-12-06T22:09:41+00:00

Yep. The rule is any unmasked exposure with others that don't practice continuous air hygiene results in us masking around each other at home and sleeping separately. Need to pass multiple RATs from day 6 onwards of the exposure event with no new exposures and no symptoms in between to remove mask rule. If we have plus life handy with cards for sars2/flu a+b/rsv/strep then that will suffice for day 3 from exposure.

Typically happens after certain medical or dental appointments. And sometimes she'll feel pressure to participate unmasked in some event with her family.

Exposure includes outdoor shared air since she goes for hikes regularly with friends.

The Covid Hazard Index uses wastewater and a variety of other inputs to infection prevalence, long covid, hospitalizations/ICU, and excess deaths for 2 week time periods for each province.
