Great write-up from @3M about how the #CorsiRosenthalBox can contribute to better indoor air quality. @JimRosenthal4 @CorsIAQ #CleanAirCube
Duct tape, air filters & a box fan. This #DIY movement caught the eye of 3M scientists & after testing, the results are clear: the #CorsiRosenthalBox works! Thank you, @JimRosenthal4 & @CorsIAQ for your relentless advocacy for clean indoor air. https://t.co/rpCCfI9z5l

Another variation on the #CorsiRosenthalBox #CleanAirCube idea, using a single 20x20x5 filter, along with a box fan

My #safethanksgiving post-dinner project with my incredibly talented brother-in-law. So clean, so well sealed.

Another DIY fan/filter!! Very nice work. This one is a fan with two filters. And a shark fin.

My children got inspired to help our schools build a #CorsiRosenthalBox and are building it as I tweet. Thankyou @CorsIAQ and @JimRosenthal4 The kids get it.
@PlasticFull @MarvinH2_G2 @PeteUK7 @ughberta @FreshAirSchools @dgurdasani1 @chrischirp @IndependentSage This is a fairly lightweight fan sold at Lowes. It looks like your gym fan is a bit more rugged. With an idea of dimensions, I could look at some ideas to make a #CRBox #CleanAirCube using a gym fan.
@JimRosenthal4 @ChurchAndCovid @DrLaPook @CbsWith @amybirn Our gr. 5-8 Sunday school class assembled one last month to complete our 7-box collection. All our groups use them when they meet during the week and we have 4 in use in our Sanctuary on Sunday mornings. Thank you!

Mark your calendar for a webinar about indoor air quality with a #DreamTeam of IAQ scientists. #DeltaVariant #CovidCO2 #CorsiRosenthalBox #CleanAirCube @kprather88 @Poppendieck @JimRosenthal4 Thursday Oct 7 noon ET, 9am PT, 5 pm in UK
Join us on 10/7 @ 12pm EDT for a webinar on #delta & reducing #airborne #COVID19 transmission in #schools.
@kprather88, @Poppendieck, @JimRosenthal4 will discuss strategies to improve #IAQ. #ventilation #CO2monitoring #filtration. https://t.co/f9bRFahsph
For people using plastic pipe as a frame for a #CleanAirCube this is a handy resource from the UK showing differences between imperial and metric PVC pipe sizes. I have used 3/4” pipe and fittings. If only metric were available, I would probably opt for 25 mm.
Learning the difference between Imperial and Metric pipe sizes can be tricky. Check out the infographic below as well as our super helpful YouTube videos which take you through the main differences!

Demo of a round fan for a #CorsiRosenthalBox #CleanAirCube. The plywood (OSB) is 21”x21” (53 cm). Fan diameter is ~16” (40 cm)
This could go on top of 4 merv-13 filters or a frame with polypropylene sheet. @CorsIAQ @JimRosenthal4 @kprather88 @BarryHunt008 @CleanAirCrewOrg
Idea for round fans #CRBox #CleanAirCube Sheet of plywood big enough for 8 square pieces <60x60 cm. Cut circle diameter of fan. Put on top of filters or frame for filter material. Thoughts? @CleanAirCrewOrg @luchioluli @PeteUK7 @fielders_80 @CorsIAQ @BarryHunt008 @LazarusLong13
Somebody posted an idea about using polypropylene wrapped around a frame instead of using MERV-13 filters. So I tried this using PVC furniture fittings and fabric originally for mask inserts in 2020 #cleanaircube #onlyatest #notsureaboutthis @CorsIAQ @JimRosenthal4 @kprather88
If you're not filtering the air, you're failing at COVID.

This is just remarkable. SARS-cov-2 rna eliminated from hospital ward air by air filtration. Which also removed a number of other bacterial and fungal pathogens.

The before-after here is amazing. A who’s who of nosocomial pathogens.

This is a mock-up of a double decker #CleanAirCube. #CorsiRosenthalBox With 2 20x25 filters + 6 20x20, it has nominal filter surface of 3400 sq in. (4 20x20=1600 sq in) @CorsIAQ @JimRosenthal4 @kprather88 @CleanAirCrewOrg @DavidElfstrom
@trendless True story: I was building a #CleanAirCube at a church picnic and the adults were asking all kinds of questions, and the children were asking for my cardboard circles.
Some firsts. First Utilitech fan. First 2” thick MERV-13 filters from Tex-Air. (Painting shroud white is 2nd time.) #CleanAirCube #CorsiRosenthalBox @CorsIAQ @JimRosenthal4 @kprather88 @DavidElfstrom Thoughts on Utilitech vs Lasko?
Today’s tweak in building a #CorsiRosenthaiBox #CleanAirCube This one has white duct tape, and the cardboard shroud painted white. 3M 1900 filters 20x25x1 (compare w unpainted shroud) @CorsIAQ @JimRosenthal4 @DavidElfstrom @kprather88
Here is a recent study at UCDavis of fan/filter combos #CleanAirCube #CorsiRosenthalBox. They studied 20” box fans with one-filter and four-filter configurations.
Great work. Thanks for sharing these test results. (It would be interesting to see if a larger shroud would produce the same optimization that @DavidElfstrom found.)
