PC Fan Corsi-Rosenthal Box Air Purifier

This project is a 3D printed PC-fan powered air purifier inspired by the Corsi-Rosenthal design. Instead of using a large box fan, this version uses multiple cooling fans to create a quieter and more compact air filtration system.The printed frame holds standard 20x20" HVAC MERV13 filters while using 200mm PC fans to pull air through the filter. This makes it ideal for desks, bedrooms, workshops, or classrooms where a traditional box fan purifier would be too large or noisy. Features:• Uses
