Model-B AC INLINE Edition

Model-B Air Filter Kit
AC Infinity Inline FAN Edition
Sorry for the significant price increases. Tariffs have hit hard.

This version of kit allows you to attach a compact inline fan to the inside of the frame. It is so small that it allows the air filter to shrink to a very small size. The fan is almost silent at 200cfm, quiet at 300cfm, but loud over those levels. At 730cfm the fan is extremely loud (think jet engine) unless a duct is attached to the filter.

The images explain a lot about the kit. If you want to know even more, watch this video on the Model-B

You will need to assemble the kit. Watch this video to see the whole process

This is the only recommended fan for this design. These are NOT included in the kit.

The design works with any brand of filter but 3M Filtrete brand filters preform the best in my tests. MERV 13 or MERV 14 filters are highly recommended. You will need 4 total filters for this kit. If you buy in bulk, the prices are better. The larger the filter, the more economical it tends to be. Large filters are also more efficient when filled with dust. Choose the largest filter that you can fit into your space.

In most cases these kits preform better than professional HEPA filters in smoke tests! Testing data on these filters can be found here:

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 filter that you choose. The fundamentals of this design are based on a Corsi-Rosenthal air filter (sometimes called a “comparetto cube” or "cube filter"). 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. View the Product Liability Disclaimer here - https://the3dhandyman.com/product-liability-disclaimer/
