I collaborated with @PeteUK7 to create a step-by-step guide to building a #CorsiRosenthalBox in the UK. Thank you to @PlasticFull @mishwoz @hazardscampaign @LibDemPatrick. You can download the PDF here: bit.ly/3W5Tadj.

The rich are continuing COVID precautions like requiring masks & tests, indoor air cleaning infrastructure, & priority access to vaccines & treatments. But they're telling the rest of us the pandemic is over because they think protecting the working class will cut their profits.
A recurring issue this winter in my neighborhood. Likely repeated across the country. Lord knows what's being used for fuel during a cost of living crisis.
For those of us concerned with air pollution, this would be very welcome news (below).
When a neighbour fires up his log burner, if I walk near his home with my PM2.5 sensor, it can reach 200ug/m3. It's normally around 5-10ug/mg. This pollution must stop.

Yes, you can do a complete build plug and play for just fans. I wanted lights in this one (some leftover LED strip from another project) and prototyped with Wago connectors, that worked well too.

Never purchase the wrong size mask again! I am probably behind the times, but I just discovered the Fit Mask app on the App Store. This app (iOS only) measures the important facial dimensions for mask sizing.

ALT Should schools use air filtration to protect against Covid-19 infections? Yes, using air filtration systems can help reduce the spread of Covid-1 9 in schools by filtering out airborne particles that may contain the virus. However, it should be used in conjunction with other preventive measures such as wearing masks, practicing good hand hygiene, and physical distancing

Check this out @JimRosenthal4 @CorsIAQ. It’s a modular Corsi-Rosenthal box crafted by Professors Marc San Valentin and Fortunato dela Peña Jr. #COVIDisAirborne

Real airborne mitigation guidance from an engineering org in a layperson-friendly format, nicely done👍🏻

Washing your hands and limiting physical touch can help you avoid germs. But how do you protect yourself from an airborne disease?

The wealthy know how to protect themselves and don't think COVID is mild
While most governments and public health organizations are downplaying the severity of #COVID and relying on a vaccine only strategy, do you know who is taking COVID much more seriously? #DavosSafe 🧵1/

You could see Covid-19 as an empathy test. Who was prepared to suffer disruption and inconvenience for the sake of others, and who was not?

Hope you've all had a good start to the new year. I'm returning after a break these past weeks. Start of this year has been tough one in between a family member health situation and some unfortunate events. Looking forward to catching up and reconnecting in the coming days.

The use of these PC fans is an incredible innovation. I purchased a kit with 6 fans and two 16X25 Filtrete filters. It is quiet and very effective. It also does not take up very much floor space. Highly recommended.
As part of @CleanAirKits I'm proud to present the newest PC fan #CorsiRosenthalBox build, the Healthy Glow.
CADR: 356.9 ±3.50 cfm / 606.3 ±5.95 cmh 🙌🙌
Power: 17.7 W
Noise: 44.5 dBA
4 Lian Li ST120, 3 Arctic P12 + 16x25 Filtrete 1900 bring high CADR to a smaller form factor.
