Last month I asked for recommendations for home air purifiers as we have wanted one for some time and have found the components for the Corsi Rosenthal box to be expensive and rather ugly as a prospect.

The price of this, with taxes and shipping included was so reasonable, that it was a bit of a no-brainer.

This AirFanta 3 Pro was suggested to us as a very reasonably priced ready-made alternative. It will purify the air in up to 3100 square feet, so has an impressive performance.

After watching the videos and reading the technical reviews, we decided to order one. It's exactly the same principle as the CR box, but much quieter, using four computer fans and with all the hassle taken out of making it. There's no need for duct tape and cardboard etc etc. and changing the filters is simple with no need to tear duct tape off etc. And it's much, much quieter than would be a box fan. It's also possible to infinitely adjust the speed of the fans, making it ideal for bedroom or other rooms where at times a quieter fan is wanted.

We liked it so well, that we ordered another one, and friends of ours ordered one for themselves.

We also invested in an air quality monitor, which was rather more expensive, but that meant that we were actually able to see the results of using these in our home environment. The air quality monitor is made in Quebec and was also recommended by the same user here.

If you have any questions about our experience with this, we'd be happy to answer them. Also I can provide a link to the air quality monitor if this is something that interests anyone. I have no connection to either company but thought that relating our experience would be helpful for someone else who might be interested in finding out about such a device.

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?

Met up with a fellow birder this morning, talked about birds and, of course, wildfire smoke this week.

They said they've been trying to find air purifiers at local stores, but found every one was sold out.

I said they could make their own, for less than $100 US dollars.

@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

How to Build a #CorsiRosenthalBox

Apr 15, 2022

"Richard L. Corsi, dean of the UC Davis College of Engineering, explains how to build a #CorsiRosenthal box. Dr. Corsi is an internationally recognized expert in the field of indoor air quality, with a specific interest in physical and chemical interactions between pollutants and indoor materials. His concept for a low-cost, accessible, and effective air cleaner, the Corsi-Rosenthal box, is now being used as an open-source do-it-yourself approach worldwide for reducing exposure to the #SARSCoV-2 virus, #WildfireSmoke and more."

#DIY box fan filters – #CorsiRosenthal box

"Also known as a Corsi-Rosenthal box, this DIY method of building your own air filter with #MERV13 furnace filters and a box fan are an easy and cost-effective way to help clear indoor air from airborne virus particles, wildfire smoke, pollen, dust, and more!

If you can seal a box, you can build one (or 100!) of these!"

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.
