#hepa — Public Fediverse posts

I keep reading about Corsi–Rosenthal boxes as DIY air purifiers that outperform all commercially available air purifiers.

You literally only duct-tape four HVAC filters together and slap any regular PC fan onto them.

US-Americans recommend the brand #Filtrete for MERV-rated HVAC filters, but in Europe that brand costs at least twice or thrice as much as in the USA.

Are there any equivalent affordable HVAC filters in Europe with a MERV rating of 8 or 13? Or do I simply have to swallow the additional cost because HVAC filters aren't as ubiquitous in Europe as they are in North America?

Hazardous Air Quality - “Everyone should stay indoors and reduce activity levels.”

The DC region has blown past the expected Code Red Air Quality warning for Friday, July 18. It was only red for about an hour before moving to the purple “Very Unhealthy” for everyone range. Now, it’s mostly in the maroon “Hazardous” for everyone range, which is the highest this scale goes up to. This is due to wildfire smoke from Canada. Good thing rain is in the forecast for tomorrow.

If you have an N95 mask, such as the 3M Aura (which fits about 80% of adults), it is a very good idea to wear it. Under these conditions, a half piece respirator is better if you have one and need to go outdoors. Most hardware stores should have them in stock if you don’t have one on hand.

Remember that smoke rises, so stay on the lowest floor while indoors if you can. The PM levels for my upstairs rooms are much higher than my lower ones. You can seal leaky windows with painters tape and plastic sheeting to create a “safe room” with HEPA air purifiers or make a CR Box (I reposted a tutorial yesterday).

"Fachleute warnen vor schlechter Raumluft: Mehr Infektionen"
https://www.sn.at/panorama/oesterreich/fachleute-raumluft-mehr-infektionen-150178543

"Schlechte Luftqualität in Schulen, Kindergärten und Arbeitsstätten senkt die Leistungsfähigkeit und hebt das Covid-19-Infektionsrisiko, erklärten Experten Freitag bei einer Pressekonferenz in Wien. Sie nannten es unverständlich und unverantwortlich, dass man in Österreich Lufthygienemaßnahmen wie Filter- und Lüftungsanlagen vernachlässige und bei der aktuellen, seit Pandemiebeginn höchsten Covid-19-Welle in Krankenhäusern und Arztpraxen nicht verpflichtend Masken trägt."

"Es ist medizinisch und ethisch nicht ok, dass sich Menschen in Krankenhäusern mit Infektionskrankheiten wie Covid-19 anstecken, wenn dies leicht vermeidbar ist"

Hey #CovidIsNotOver people! I start a new job tomorrow (fully in person) & am a little nervous about keeping myself safe. Here’s what I’ve got in my toolkit:

1. #3MAura and #VFlex #N95 #Respirators
2. #Hepa purifier for my desk
3. #Co2 monitor
4. #Enovid #NONS nasal spray
5. #CPC mouthwash
6. #SipMask

I’ll only eat outdoors, weather permitting; otherwise I’ll find a private room & run the purifier before unmasking. I will use #NasalSpray several times per day.

Anything I’m forgetting? 😷

Hoping to get some input from #HVAC #Engineers and other experts: in a school built in the 70s that originally had no walls and is now divided up into classrooms via a mixture of full height, 3/4 height, and half height walls and dividers...would getting walls & doors be helpful or harmful from a #CleanAir standpoint? HVAC has #MERV13 filters, & the building has a handful of #HEPA air purifiers, but very few windows.

We can stop #Covid easily.

We can't stop #cholera with vaccines. We stop cholera with water treatment plants, because cholera is in the water.

Also water filters and UV for long-distance hikers etc.

We stop #Covid with air cleaning -- #HEPA filters, #MERV13, #CorsiRosenthalBox -- because Covid is in the air.

And with #respirator #masks
( #N95 / #P100 / #P3 / #FFP3 / #FFP2 / #KN95 / #KF94 etc).

Side benefit: we also stop #flu and #RSV.

It's a #ParadigmShift.

"We follow #CDC Standards" is the new "Our doctors are licensed priests who pray before their surgery (but don't wash their hands)"

Clean water stops cholera.
Clean air stops Covid.

Medical staff need reusable #P100 masks. Medical exam rooms need portable #HEPA filters to bring the #CADR up to ACH 12.
