The air filter kits are finally here! This video covers Model-A design and construction. It's taken months of work and countless prototypes to finalize these designs. I hope you like them! If you do or don't let me know why in the comments.

Both kits work with 2 drum fans that are linked below. Any brand filter should work (7 have been tested). This design uses 16x20x1in filters.

================

The full kit for the Model-A is currently replaced by an upgraded Model-B. You can check it out here: https://www.etsy.com/listing/1373712349

You can still build the Model-A with free plans.
Let me know if there are any issues anything.

Keep in mind this is a do-it-yourself style air filter kit. Correct assembly is required to filter the air passing through the device. Results with this device are dependent on the fan and filter of your choosing. The fundamentals of this design are based on a Corsi-Rosenthal air filter (sometimes called a “comparetto cube”). The quality of filtration achieved by these designs have not been independently tested or verified. Viruses and other extremely small particles may not be filtered out by the device. Use at your own risk.
