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!

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 %.

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

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:
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!

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

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

The DIY ERV (energy recovery ventilator) efforts by

and

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.

Makes ventilation more important, transmission goes approx. with its square, not just linearly

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.

Got a massage wearing a comfy LivingGuard mask and our battery-powered Cherry Exhalaron blowing up from under the headrest. Quiet supplement to the noisy Levoit 300 in the corner. Masseuses take note!

Reduce the chance of in-home pre symptomatic transmission with 5-6 air changes per hour in frequented rooms. We offer the quietest, most energy efficient DIY air purifiers:

Hey yo school administrators frozen like deer in the headlights... Hiring good people is a lot of work. Maybe you really do need to protect them from all the respiratory illnesses going around...

That common loss of smell with covid is also common BRAIN DAMAGE with covid. We need to stop reinfections—hopefully the damage can heal and test scores go back up. But damage worsens with reinfection and healing takes at least 6 months!

Last week during the Cali storm our power was out for a couple days, but we still powered our in the bedroom overnight with this PowerBank . What other HEPA gets near 5 ACH in a bedroom for 16 hours on a 20000 mAh pack???

This makes the Luggable line the first MERV13 Corsi-Rosenthal boxes to be officially certified against UL507 electrical safety standards for fan assemblies with filters in place. (And also the first CR Boxes to have AHAM AC-1 CADR tested officially by Intertek).

We gifted one to a pregnant friend at Christmas who stayed safe with baby last week despite sleeping in same bed as dad the night before he tested positive. Studies show people are most contagious the day before they test positive.

We just got a chance to update the XXL Kit Assembly guide to properly show the arrangement of the 4 equal-length sides. Handle on 4-fan panel goes on top, tension wire vertical. Sorry this was totally not clear before! Check our Kit Docs page:

Good news for the Brisk Box and other budget CR Boxes. The 3M Filtrete line is so good at small particles you can use anything from MPR1085 to MPR2500 in your PC fan kit with little difference in Dust or Pollen-equivalent CADR!
Ran Filtrete MPR2500, 1900, 1500 and 1085 with a 5-P12 16x25x1
@cleanairkits
Luggable. 1900 is CADR king 👑 but 1500 and 1085 are very interesting budget options. 1085 is half the price with a 4-5% CADR loss compared to 1900. 🤔

On this Memorial Day Weekend, we believe our invisible enemy can only be defeated with the scrappy solidarity the Greatest Generation brought to their world war. We're making it extra easy with plastic rivets and a 10% off sale on powerful SickleFlow fan kits: SICKLESALE23
