   I have a JDS 750. Technically, it's an ambient dust collector, meaning it collects dust that is suspended in the air. The charcoal filter is for odors, not fumes. You may not want to run an ambient filter, or any electric motor in a fume filled environment, if those fumes are flammable. My older model, been on the job over 10 years, has two main speeds and each of those can be controlled by an infinite knob. You can run the collector at a whisper or a torrent. It makes about as much noise as a large shop fan when running full power.

   I use their electrostatic filter. It's metal and fully washable as are the felt filter bags inside the machine. The charcoal filter is expensive and doesn't last very long, maybe a year. You can also use furnace style filters.

   The JDS is a very well made collector. I also have a Penn State which is a joke in comparison. You will notice a big difference in how much dust settles around your shop. It's not a solution for an inadequate direct dust collector attached to your machines. In combination with a direct collector, it will make a big difference in your shop air.

   I have neither a spiffy dust collection system, nor an ambient filtration unit, so I may be talking through my shop hat here. But, I would think the manufacturer should have noise specs, and CFM (cubic feet per minute) specs for the unit. Compare the CFM spec to the volume of air in your shop to determine how long it would take to filter the entire volume of air.

   If you actually have fumes, as the other poster mentioned, the safety concerns are quite different.
