FAQ: best air filtration system

A micrometer or micron is a unit of measurement corresponding to one-thousandth of a millimeter. Dust particles are referred to by their size in microns.

The CFM rating on the air filtration system corresponds to the rate of air flow in cubic feet per minute.

It’s not so much that air filtration systems are more effective, rather that they perform a different scope of duty. Whereas most dust collectors excel at removing large fragments of woodchips and other workshop debris, the best air filtration system deals brilliantly with those lethal finer particles.

Avoid cramming it up close to a workbench or wall since this will obstruct the air flow. A smart benchmark is to locate your air filtration system roughly one-third of the way down the longest wall in the workshop away from any obstacles. Set it 6 inches or so away from the wall and you’ll optimize efficiency.

Fortunately, getting up and running with your air filtration system is not a difficult job. Once you’ve thought about the ideal placement close to a power outlet, simply follow instructions to hang it up using the hooks provided.

No. If you opt for a beefier unit, it’s highly likely to demand a 220-volt circuit so do your due diligence to avoid getting an air filtration system unfit for purpose.

Absolutely. One of the serious problems with fine particles of dust is that you can’t see them so it’s easy to overlook how they can wreak havoc on your allergies and sensitivities. Take action with an air filtration system and you’ll be able to happily work away without your allergies being inflamed.

An ability to fine-tune the speed and, resultantly, the air flow, means you can match the output to the application. Variable speed is not an outright necessity but the best air filtration systems pack this feature to enhance efficiency depending on how much dust you’ll be generating.

High efficiency particulate air (HEPA) filters are the gold standard when it comes to removing the smallest of particles. Getting rid of dust down to 0.3 microns, the best HEPA filter is essential if you are working with toxic materials.

The inner filter needs cleaning every third day of use while the outer filter should be cleaned after each day in the workshop. Make sure, too, to replace the filter once it shows visible signs of wear.
