(Be aware that if the 12" fan is out of stock, the 14" fan will appear in it's place!)

ALTERNATE FAN OPTION - If you buy a 20"x30" or 20"x20" filter kit, it will support a 14" Cloudlift S14 WALL FAN. It is about 10% more powerful than the 12" fan. If you want this option, please add a "note to seller" that you want this option at purchase time. The 16" wide kit (16"x20" etc.) will also accept the 14" S14 fan but it will only mount to the outside of the kit (does not fit inside).

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:

NOTE: The 14" filter version of this kit is not wide enough to mount the 12" fan on the inside of the unit. It must be mounted on the outside using the thumb screws.

There is a lot of information on this page. If you have any questions about it or a specific use case for the filters, contact me! I am happy to help.

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/
