INTUITIVE CONTROLS: Allows you to set different speeds.
It works like a magnet and picks up the most dangerous dust particles from the air down to 0.1 microns. This filter technology has been patented.
ELECTROSTATIC FILTER: It has a 3000-hour life and is easy to clean.
HIGH SPEED: 50.8 dB on High speed setting and 41.3 dB on Low speed setting.
Energy Star certified and certified by the California Air Resources Board (CARB).
Cleaner air and safer air will make you feel better. The new PM1250 AFS with Micro Dust Collection Technology is the most cutting-edge air filter for woodworkers in the world. By removing microscopic particles from the shop environment, Powermatic’s PM1250 cleans the air in the shop with ultra-quiet efficiency. Most dangerous dust particles in the air are attracted to and caught by special filter technology, which works like a magnet to draw them in. A 680-square-foot area was found to have 99.7% less airborne particles when it was cycled five times an hour. Engineered fan blades increase airflow and cut down on noise. Multiple places to hang it in the shop, as well as a handle on top to make it easier to carry.
This is not as good as the old PM1200.
Even if I put my Dylos shop air particle counter right next to the PM1250’s exhaust stream, I can’t see a big difference when it comes to shop air particulates. PM1200 is very good at cleaning shop air and has a clean exhaust stream that can be measured. This is not the case.
People who know how things work say that the PM1250 is in fact cleaning the air, but it does so with very little “efficiency. It only removes a very small amount of particulates each time the air passes through it, so it doesn’t do a very good job. A HEPA filter, on the other hand, removes almost all of the small particles in one pass.
The older PM1200 is not a HEPA filter, but it does a very good job of getting rid of a lot of the dust in each pass (maybe 80 percent ). So much air moves through it that it cleans the air very well and quickly. It doesn’t need to be HEPA because it moves so much air.
On the other hand, the new PM1250 moves a lot less air, but it also only removes a small fraction of the particles in each pass through (maybe 20 percent ). When this happens, a small amount of particulate is removed from only part of the air. This is called “double-whammy. Because of how much dust is made in any shop that is thinking about getting an air filter, the end result is not very good.
On the bright side, the PM1250 is very quiet. However, when it is turned off, it isn’t as quiet as my PM1200. It’s true that I’m being sarcastic, but I have to say that when the PM1200 is turned off, the performance comparison to the PM1250 is more like that of the PM1250 than different.
Electrostatics are used to clean the air in the unit. I’d like to say that it removes the really, really, really small things (such as dust and pollen) from the air, but my particulate sensor doesn’t show that, so I don’t know if it does that.
It’s a shame, but this machine isn’t the best of both worlds. Even though this product is bad, I can’t think of any situation in which it would be a good idea to buy it. I’m giving it back.
