John Smith was cleaning yet another reusable air filter one day, when he noticed that after shaking it out, it still held a lot of water. As anyone would, he started throwing it in the air, spinning it as fast as he could to remove more water. That worked well, and then came the brainstorm: “So I walked into my garage and found my hand-held rotary seed/fertilizer spreader. My dog (Prince) had already chewed up the top, so I finished the job and cut the rest off. I duct taped the filter to the spinning part and started spinning the crank: The faster it spun, the more water came off.  So, I started working on a design that would automate the whole process.”

Eureka! The Revolution air filter cleaner was born. It’s a pretty simple idea, but the execution is everything. A 17-year R&D mechanical engineer, John Smith has been busily perfecting the Revolution for the last few years, raising money – and hopes to begin delivering product by July 4.

“Thankfully, CAD (computer aided design) software had become more affordable, and then affordable and dimensionally accurate 3D printing came online,” says Smith. “We started working on several iterations over the last three years and lots of testing has taken place. As we found issues, they were resolved and tested again. We got to a point where we had high confidence in its operation. Then came COVID 19, and another year of R&D we didn’t really need.”


People install K&N-style air filters on their vehicles for increased airflow and performance, but that performance doesn’t last long if that oiled-element filtering medium isn’t kept clean. In dirty or dusty environments, that means frequent cleaning, and it’s a dirty, labor-intensive chore that can grow old quickly if you have multiple vehicles.

Enter the Keep-It-Klean Revolution

Basically what goes on is you clamp your filter to the base of the Revolution (which also automatically centers it), replace the lid, and push the button. The Revolution plugs into a regular 110v outlet, or can be powered by a car battery in the field.

After. Ahhhh…

The filter spins on the turntable. Internal reservoirs hold a gallon of water and two cups of cleaning fluid. At the proper intervals, cleaning fluid is automatically applied via Keep-It-Klean’s adjustable nozzles, followed by a rinse cycle. About a half hour later, thanks to the miracles of soapy water and centrifugal force, you’re left with a nice, clean, and mostly dry filter. From there, all that’s left is to let the filter dry completely, then re-oil and re-install.

Keep-It-Klean says it’ll work with any filter 2 to 7 inches in diameter, and 2 to 7 in in height. A bigger version is also in the works for commercial vehicles, as well as one to clean flat air filters.

Smith debuted Keep-it-Klean’s Revolution at the SEMA Show in 2019, and won a SEMA Global Media Award – one of about 200 awarded of more than 1,800 products in the New Product area that year. After that, Keep-It-Klean was featured on an episode of Motorhead Garage on Motortrend TV.

After that segment aired, Keep-It-Klean received hundreds of emails from interested parties. Two years later, the pieces are all in place and Keep-It-Klean is taking pre-orders, upon which it’s offering a discount as well as free shipping. If you’re interested, you can watch the 3-minute Motorhead Garage video, and pre-order a unit by clicking Parts are sourced from around the world, but will be assembled in the US. Smith, a former Marine, hopes to assemble a workforce of veterans to get things rolling. Also, spinning and cleaning. Great idea.
