Aluminum Frame PC Fan Corsi-Rosenthal Build (2023)

After three generations of DIY air cleaner cubes, Zack Deis designed a quieter, more professional-looking version using a custom aluminum frame and six PC fans. The build costs around $300–350 CAD, assembles in 30 minutes, and features easy filter replacement. It's been running in homes and offices for over a year, offering a 'buy it for life' alternative to commercial units.
The 'buy it for life' design with easy component part replacement and highly accessible filters are very attractive features.
