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?

@alisynthesis As a long haul strategy, the modular #OddCube #CorsiRosenthal Box should be released later this year - 3d Printable or kit-buyable, uses any brand of 10" furnace filters, runs pc fans for low energy use and easy replacement, has a cool shape (a #cuboctahedron !) - see their #Kickstarter https://beige.party/@beadsland/116889416498442008 #HEPA #DIY #3dPrinting #Wildfires #AirQuality

I facilitated an online workshop for @freetechproject tonight and it's the first time we tackled technology to fight #Covid (Co2 monitors, air purifiers, #HEPA, #CorsiRosenthal boxes, #NukitTempest, etc) as well as why this is important (what Covid is, how it spreads, etc) and the small (predominantly older) group was very open to the ideas, sincerely inquisitive about the topic, interested in reducing risk, aware of inclusion issues, and sensitive to my own experiences as carer for a partner disabled by Covid. I'm also realising that people genuinely refer to "Covid" in the past tense sometimes because they wrongly associate it with government policy, while at the same time they very clearly understand that #CovidIsNotOver. My point is, keep tackling the topic, and keep giving folks the benefit of the doubt -- humans are of course good at heart and state policies, and obviously the establishment media, may very well indeed not, in fact, reflect people's actual concerns about Covid.

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? 😷

All kinds of fruit in your #smoothie is fun
Things that grow in the summer sun
It's kinda bad, however, when the smoothie blend
May cause your liver to fail, and end
