Another design is using 2 20x25x1 filters, taping them to the sides of the box fan and then to each other so they sort of make a triangle, then cutting cardboard to make a top and bottom to the triangle.

This was discovered as a more effective design during the 2020 US west coast fires.

I always advocate for any in person learning/experience you can get your hands on!! Look up reputable classes taught in and around your area, sometimes there are pretty decent starter classes especially for parents/kids!

(Additionally, the Iowa and Kansas Schools for the Deaf have classes available for state residents!!:)
