Granted, I used a blower fan as instead of the box fan the canonical design uses.
Due to a series of unfortunate events, we’ve found ourselves with a reasonably clean basement. One of my wife’s biggest complaints about the basement had always been dust. Dust from my very infrequently used wood-shop. Dust from the litter box. Dust from… well, dust.
The new basement seemed like a good excuse to take a crack at the dust situation and this design sprung into mind.
I built it with four 16x25 MERV 11 filters, some plywood, some 1x4s, some plumber’s tape to hold the fan in place, and the aforementioned blower fan. I could have gone for a higher MERV rating, but I didn’t feel the need to go super overboard. I can also crank the fan for multiple consecutive passes. That’s the whole idea of the design after all.
The box itself is only held together with tape and the weight of the fan. Now that the basement is more together I might model and print some brackets to make the box more solid.
One cheap motion sensor plug later and the air down there is honestly pretty fresh
I’ll never stop thinking about how dumb it is that someone slapped their name on a thing people have been making for decades…
Are you talking about the Kennedy center?
I don’t mind it. Their contributions include showing how efficient the design is (a lot more efficient than many commercial consumer air purifiers) and also popularizing the design, which the name helped a lot with. Not the particular name, but just giving it any name helps a lot with popularizing the design.
It’s not like they’re making any money off it.
I should also point out that in science it’s extremely common to name things after people who researched them, even if those things were well known long before they got that name. Especially funny is when taxonomists will name a species that already had a name known to the indigenous people of that area for literally thousands of years, and they name it after Bob the taxonomist who visited the area in the 1970s…
This is the story behind a lot of tech. Wankel engines are a good example. Wankel developed the seal tech that made rotational piston engines viable.
Haha, agree. These have been a fixture in woodshops for… quite some time. I suspect they’re also used elsewhere.
Maybe their contribution was the instrumentation that showed that filters that are not rated for HEPA level filtration will still basically eliminate viral load with enough passes.
there were no square boxes before 2020.
Corsi was Dean of Engineering at UC Davis, he should be embarrassed.
