Here's a demo of our Exhalaron on a nightstand sucking in fog above a pillow over 1m away. Even the fog that starts going the opposite way gets pulled into the 90 cfm vortex. This is way faster than letting breath mix into the room then pull out with floor purifier!
Exciting news for clean air aficionados facing stickler administrators... CleanAirKits has passed UL507 electrical safety compliance testing at Nemko Labs and now carry the US/Canada UL507 mark on factory assembled Luggable/XL/XXL and Exhalaron models!
@CDCDirector
Here's a better message. PREVENT infection by wearing masks and establishing 5ACH of clean air in each room of your home as CDC recommends. INSIST on this in ALL of your children's classrooms. Ask the school for documentation that they've reached it:
This study estimates an 81% reduction in university classroom transmission (60% long range) by raising air cleaning rate from existing negligible to 15 cfm/student. Cost of that with our Luggables is about $10/student for first year!!! Let's save some brains!
From a study on the SARS-CoV-2 infection in a university classroom,
"The average interpersonal distance in university classrooms is 0.9 m, with the highest proportion of face-to-back contact at 87.0 %.
The risk of infection of susceptible students per 45-min lesson was 1 %.

A Corsi-Rosenthal box is THE crucial baby shower gift of the post-as-in-postman-comes-back-everyday pandemic era. We gifted one to a close friend, this week hubby caught the vid from a parent event, but mama and vulnerable baby are safe so far. Mother hen knows!

We've always jumped on projects where we foresee a large impact and bring a unique skillset. In an unopposed pandemic, PC fan purifiers deserved a push.
In 2023 CleanAirKits shipped about 30,000 PC fans, enough to cover 33,000 people in 40cfm clean air.
When
@JimRosenthal4
says "Filter + Fit + Flow = Effectiveness", what does he mean? A proper diagram can help visualize both CADR & filter efficiency, and which matter when. The safest room removes the most dangerous particles fastest, agreed?
@clhubes
Try a combination: 1) masking, 2) anti-viral nasal sprays, 3) air purifiers providing ASHRAE241 recommendation of 40cfm/person in occupied rooms. With quiet PC fan purifiers, that's about 1 fan per person. Should see ~80% drop in airborne contagions
We are in a silent war with an invisible enemy that's already caused more deaths worldwide than any war but WWII. That exhausting wariness--fitting masks & sprays, checking CO2, placing CR Boxes--is soldier discipline keeping us healthier for another day.

3 people in a row talking about how they already got it this summer so don’t have to worry for a few months. Not realizing we never know whether that will hold for next variant
When fighting an exponential process like a viral pandemic, factor of 2 wins are nice. Our Luggable Kits come with random small parts pre-attached, so you can install the fans and pull the box together in just 15 minutes. And get twice the CADR as a HEPA...
Dusting off those perfect wrapping skills was a secret thrill for parents this week ... so keep going with a $99 silent PC-fan air cleaning kit!
This 4-fan taped kit covers 5-persons w/40cfm each. Perfect for small-medium rooms up to 300 sq ft!
We got cool experiments to share for twitter-versary! This is the .7um drawdown at 7 locations across a 600 sq ft space from a Luggable XL against the wall. Notice the near perfect synchrony even at far corners! Surprisingly, clean air reached all 7 within a couple minutes!
@CDCgov
Your approach encourages ignoring the risks of -3 IQ points plus 20% long-term pain and health problems per infection. The science recommending 5 clean air changes/hour in indoor spaces is buried in your site. Be even safer than 5ACH with this science:

Your flippant guidance downplays long-term risk including avg -3 IQ points per infection, exercise turning poisonous to muscles, and 200 other symptoms. Trumpet the 5 ACH guidance buried on your site instead. Here's some effective clean air R&D:

@jzux
Start by placing purifiers in most frequently occupied rooms like open family/dining, then shared bedrooms. The Exhalaron can go right on a dining or coffee table to intercept and clean breaths before they spread into the room. Also fits on bed stand or mounts on walls

Last year this time we were in the midst of our only COVID infection (a month after launch) and wisely uninvited from family Christmas dinner. Took a whole year to be pain free, body and mind, but still sad because so many institutions are still in denial...
We of CleanAirKits are stubborn about applying great science to well-being. This is a time to be relentless with clean air, not turn a blind eye. We’ve all heard stories of COVID caught in conference rooms. It’s time that became OBSOLETE.
This has gone unstated too long in our community. Letting everything drop to you-do-you and Herculean/moralistic efforts by a few was a big mistake. Air cleaning has collective benefit without begging for compliance. Nasal sprays do no source control - more individualistic
Okay so the thing that's starting to annoy the hell out of me a lot right now is people saying that respirators need to be perfectly fit to be effective. This isn't exactly true. People need to start looking at this as a system. You need to look at system wide efficiencies.
What's the ideal placement for purifiers? Between an unknown infectious source and other occupants -- hence the basic advice -- center of a room. A range of CR boxes spread thru most occupied areas have the best chance to intercept. Here's a Tower of Power by a kitchen island

Really need to investigate the air change rate in that classroom. When ten or more get it that strongly suggests non existent ventilation. It’s been in our kids classrooms too but ventilation is good so not many others get it.
@gershbrain
We've gone back to basics on the quietest, most efficient ways to clean air: 15-20dB quieter and 1/3 energy of HEPAs. And students gain agency over health building kits themselves. Every classroom should have big units and every dorm room an Exhalaron
Yup we were just telling someone this week that 100 kids in a gym takes 10 Luggable XXL (or 13 Brisk Boxes) to hit the 40cfm / student ASHRAE classroom level. (And ASHRAE has higher per person flow suggestions for gyms because heavier breathing!)
This is so true. I saw an acquaintance proudly post that they bought a Levoit Core 300 for a gym space, "and now the air is clean!". The space is huge! That cute lil Core 300 isn't gonna do anything. They probably needed 10x Smart Air Blasts at a minimum for that size
Folks this is so bad. Saying they don't have to mask when infected means MOST WON'T and our kids brains are gonna be turned into porridge within a couple years. REMEMBER THIS IS LIKE LETTING SOMEONE WITH A BASEBALL BAT BEAT ON YOUR KIDS IN THE CLASSROOM. React accordingly!
I finally got notice that my kids’ school is adopting the new
@CAPublicHealth
Covid isolation policy. 😡
They have sold their soul to capitalism.
And look 👀… they say you don’t even have to mask for the 10 days.
🦠Everyday is “Bring Your Covid to School” day!! 🦠
Our kits are not just the most economical path to quiet clean air. Thanks to the large four-filter surface area, they're the most energy and noise efficient. The 4-fan pillar gets 200 cfm covering 5 people just like our 5-fan, 2-filter Luggable!
Absolutely no excuses for this recklessness. Can't decide today whether the hierarchs who've normalized this did it just for the "economy", or because they are planning something much worse for us.
@jonfavs
Democrats aren’t even being smart about pandemic mitigations. Putting a couple PC fan DIY purifiers in each US classroom would cut airborne pathogen transmission at least 50% (like universal cloth masking) for less than a billion dollars.
Do you know any bus drivers? They're in short supply nationwide. They can easily run one of our PC fan CR Boxes off a PowerBank or their 12V cigarette lighter. That or an open window might save their career.
« Bus drivers were at double the risk of being hospitalized for severe COVID-19 in the later stages of the pandemic, and several occupations in education and healthcare were also at risk of serious illness »

& you don't want it for your family, friends, community. Literally begging you now. Stop forward transmission. Stop infecting each other. Stop re-infecting each other. The horrors I have heard about & read about in just the past few days /1

We’ve seen all the research showing COVID increases risks of serious illnesses in the young like this. Parents, to help you get serious about pushing purifiers at school, we have lower cost options and new experiments coming!
I've received two emails in the past two days about students I teach.

2) 15-year student was sick over half term and has been hospitalised with bacterial pneumonia.
@60Minutes
The DIY community discovered MERV13 filters + PC fans can also clean classroom air, stay 15-20dB quieter than HEPAs, & use no more energy than a LED light bulb. Cover your home with 6ACH too for that 80% reduction in spread of flu, rsv, strep & COVID:

Performers lose invigorating music and dance to long COVID, but they're not the only ones. Music teachers are exposed to dozens of students per week. If not embedded in a stiff bureaucracy, we can easily protect them with cleaner air!
@Iamjacksdisgust
Make sure you've got 5-10 ACH filtration in the occupied rooms of your home so she's substantially less likely to transmit to you while presymptomatic.
@DcrInYYC
This is the curse of having a mind finely tuned to reality. You may see solutions to problems the world hasn't or doesn't want to see. But staving off collapse is a gargantuan challenge at this point that needs all hands on deck.
Alex Kessler has put together a shorter explanation of the principle championed by
@CorsIAQ

@JimRosenthal4
: less restrictive filters ~MERV13 outperform HEPA as room purifiers. This tiktok is a good share for those new to our movement!

Parents, EVERY dorm room needs a Corsi-Rosenthal box so your kid has a fighting chance from (asymptomatic?) roommates. Even our smallest 5-fan Arctic adds 7 air changes per hour to typical 240 sq ft dorm room, and 7-fan SickleFlow can add 12 like a hospital isolation room.
What makes our Ultra the most versatile HEPA purifier? It does 5 ACH in a bedroom so quietly you can place it on the nightstand. High flow & suction near the pillow helps pull breaths in for cleaning before they drift to your partner's side:

And what’s missing here is aggressive deployment of air cleaning to squash superspreader events that keep transmission going full bore. It’s not that expensive but action is frozen everywhere!

Introducing the Exhalaron Double-Barrel HEPA, 119 m^3/hr (70 cfm) DUST CADR yet barely audible at full strength, substantially improving air quality in its vicinity wherever it goes, using so little power it may embarrass Energy Star.
What's so damning about this is that school administrators aren't even willing to accept that our little virus friend IS CAUSING the rapid deterioration in attendance and test scores. TOTAL leadership FAIL
Most school systems don't care about the health of you & your kids because it's all about attendance/test scores. Schools are one of the main super spreaders of covid & now the push is on for covid+ kids to be in class. The US has consistently shown what NOT to do in a pandemic.
The DIY ERV (energy recovery ventilator) efforts by
@open_erv
and
@alexkessler0
are an important complement to DIY CR Boxes because unlike purifiers, ERVs can ventilate (reduce CO2) air-tight homes without losing much heat and reduce viral aerosol lifetimes.
1/ A very important finding from the Bristol group: higher CO2 indoors makes the SARS-CoV-2 virus survive much longer in air
Makes ventilation more important, transmission goes approx. with its square, not just linearly
Employers also need to be proactive about cleaning air in their workplaces, and educating workers about the need for clean air at home and in their kids schools!

I don't know who needs to hear this but...
Build a ton of PC fan CR boxes now. If your cohabitants give up masking later, you'll still have a passive line of defense which reduces inhaled dose, and could possibly prevent infection in combination with vaccine leaky immunity.
