What is a Corsi-Rosenthal box?
A Corsi-Rosenthal box is a simple, DIY air filter that can be made with a box fan, some filters, and some tape. It works by pulling in dirty air from the room and passing it through the filters, which trap pollutants and allergens.

Instructions:
- Cut a hole in the side of the box that is big enough for the box fan to fit through.
- Tape the furnace filters to the inside of the box, making sure that they cover all of the open spaces.

- Turn on the box fan and let it run for several hours, or overnight.

How effective are Corsi-Rosenthal boxes?
Corsi-Rosenthal boxes have been shown to be effective in reducing the levels of pollutants and allergens in the air. One study found that a Corsi-Rosenthal box could reduce the levels of PFAS (chemicals found in cleaning products and textiles) by 40%-60%. Another study found that it could reduce the levels of phthalates (from personal-care products and building materials) by 30%-60%.
Are Corsi-Rosenthal boxes better than HEPA filters?
Corsi-Rosenthal boxes are not as effective as HEPA filters, but they are much cheaper and easier to make.

How to care for a Corsi-Rosenthal box:
To keep your Corsi-Rosenthal box working properly, you should change the furnace filters every 3-6 months. You should also clean the box regularly with a damp cloth.
