The Supermax SUPMX-810650 Air Filtration Unit is a ceiling-mount shop air cleaner built to pull lingering airborne dust out of the air after sanding, sawing, routing, and general woodworking. This is an air filtration unit designed for cleaning airborne dust in a workshop. Model Number: 810650. If you already have dust collection at the machine, this unit handles the fine dust that still stays suspended in the room.

What makes this unit worth looking at is the airflow range. With three speed settings rated at 540, 730, and 1200 CFM, you can run it lower for background cleanup or turn it up when the shop gets hazy after a heavy sanding session. At the highest setting, it is designed to recycle all the air in a 20 foot by 20 foot by 8 foot space up to 22 times per hour. In plain terms, that means it is meant to keep small to mid-size shop air moving instead of letting dust hang there until the next day.

Filtration matters more than raw airflow, and the Supermax setup covers both stages. The outer washable electrostatic filter catches larger material first, which helps protect the inner filter and keeps maintenance straightforward. Behind that, the inner filter captures particles larger than 1 micron to improve the air coming back into the room. That is the kind of detail that matters for woodworkers and cabinet guys who spend hours around sanding dust, not just chips on the floor.

From a jobsite practicality standpoint, this unit is built to work overhead and stay out of your way. It includes the hardware for ceiling suspension, plus rubber feet if you need another placement option. The remote control is a real convenience here, especially once the unit is mounted high or tucked where you do not want to climb up every time you need to change a setting. You can handle on/off control, speed changes, and timer programming without stopping what you are doing.

The timer function is one of those features that sounds small until you use it. With settings from 1/2 hour to 4 hours, you can leave the filtration unit running after you finish cutting or sanding and let it continue cleaning the air while you step away. That helps clear the shop without wasting run time all night. The dirty filter indicator also helps, because airflow only works when the filters are not loaded up, and this gives you a clear reminder to service the unit before performance drops off.

Power comes from a 1/5 HP, 120 V, 60 Hz, 1 phase motor, and the unit includes a 6 foot cord. It is a corded shop air cleaner, so there is no battery platform to worry about and no drop in runtime as the day goes on. At 73 lb, it is not a lightweight accessory, but that weight makes sense for a metal-bodied air filtration unit designed to hang in place and do steady work over time.

This air filtration unit makes the most sense for woodworking shops, cabinet shops, garage workspaces, and serious DIY setups where fine airborne dust is a constant problem. If you are cutting sheet goods, sanding hardwood, shaping trim, or doing any work that leaves a cloud hanging after the machine stops, this tool fills the gap between source dust collection and a cleaner breathing environment. It is not a replacement for a dust collector at the tool. It is the follow-up step that helps make the whole shop more livable.

Why the Supermax SUPMX-810650 Air Filtration Unit earns its spot

This is the kind of shop upgrade you appreciate more the longer you work in the space.

• Who it's for: Woodworkers, cabinet makers, and serious garage-shop users who already collect dust at the source but want cleaner air after cutting and sanding.
• Why it stands out: The combination of 1200 CFM top airflow, remote control, timer, dirty-filter indicator, and dual-stage filtration makes it practical instead of fussy.
• Worth knowing: This is a corded overhead air cleaner, not a substitute for a dust collector connected to the tool. Think of it as the second line of defense that helps finish the job.

• What kind of space is this unit designed to clean? It is designed to recycle the air in a 20 ft x 20 ft x 8 ft space up to 22 times per hour at the highest speed.
• How fine is the filtration? The inner filter captures particles larger than 1 micron, and the unit also uses an outer washable electrostatic filter.
• Can you control it after it is mounted overhead? Yes. The included remote control handles on/off, speed adjustment, and timer programming.
• Does it have an automatic shutoff option? Yes. The timer can be set from 1/2 hour to 4 hours so the unit can keep cleaning the air and then shut off on its own.
