Protect Yourself and Loved Ones from
Wildfire Smoke & Viruses
For excellent indoor air-filtration,
build yourself a Corsi-Rosenthal box.
Engineer Richard Corsi
(Dean of Engineering University of California / Davis)
partnered with
Engineer Jim Rosenthal
(CEO of filter manufacturer Tex-Air Filters)
to design this relatively inexpensive indoor
air-cleaning system during the Covid pandemic.
Their goal was to reduce the risk of infection
by reducing the levels of airborne viral particles in indoor settings.
The “box” is also effective for removing
wildfire smoke particles in your home.
(Keep all windows closed while running it).
I personally experienced great relief
during two-weeks of hazardous air conditions
when wildfires were out of control in our area.
My Corsi-Rosenthal Box
Below are the links to the exact materials
I used to build the “box.”
IMPORTANT
I learned that we should be most careful when choosing the filters…
some inexpensive brands could offer very little protection.
The goal is high-quality air filtration.

The Filters:
Need 4 to make “the box.”
So buy 2 of these (each pack has 2 filters)
Duct Tape
(only need 1 roll)
For the cardboard bottom…
Use the cardboard box that one of the filters came in.
The cardboard box is about 3-4 inches deep, and it’s sturdy.
Taping it to the bottom of the Corsi-Rosenthal box helped to secure the box “structure”— and also made it easy for me to slide the box out (from under the table) when I needed
to use it.
You’ll want to maintain about 3 feet of space on all sides
while the fan is running for the greatest efficiency.
