Powermatic PM1250 Micro Dust Air Filtration System

Exceptionally quiet, portable, and most importantly, effective, filtering particles down to 0.1 micron in size.

Item #
92% of 100

If you'd like to minimize the airborne dust in your shop, turn to the incredibly quiet and efficient PM1250 Air Filtration System. The PM1250 employs an electrostatic filter that attracts and removes particles as small as 0.1 micron in size. It cycles the air in a 680 square foot space—the equivalent of an oversized 2-car garage—up to five times in a single hour. When set at the lowest setting, the system is about as quiet as a library, and when on high, it's quieter than normal conversation. Unlike most other air filtration systems, the PM1250 is portable and freestanding, meaning you can carry it to wherever filtration is most needed, then simply set it on the floor or the bench. The angle is adjustable using the knobs on the side of the unit. If you like, it can also be mounted to the wall or ceiling.


  • Electrostatic technology filters particulate matter in the air down to 0.1 micron
  • Filter is specially designed to be easily vacuumed out, extending the filter life and lowering operating costs
  • Cycles air 5 times per hour in a 680 square foot area (oversized 2 car garage/shop)
  • Freestanding and portable—top-mounted handle allows easier carrying
  • Quieter than normal conversation at 50.8 dB on high speed setting
  • As quiet as a library at 41.3 dB on low speed setting
  • Over 3000-hour filter life—filter is easily accessible for cleaning and easily replaced when needed (#69905, sold separately)
  • Blades are specially engineered to increase airflow and reduce noise
  • Remote control allows activation from across the shop
  • Multiple speed settings for varying applications
  • Timer settings let you leave the unit on and clean the air for a period of time while you are away
  • Certified to CARB (California Air Resource Board) and Ozone emission standards
  • Energy Star Rated

Clean and Quiet
Very happy with this purchase! The filtration fan is super quiet (which has led to it accidentally being left on overnight!) It does a good job of taking the fine particulate out of the air. Highly recommend as a better option to loud ceiling mounted filtration systems.

Clean Air
We have a 38x60 shop with 18 foot ceilings. Probably too big for this unit, but we can really tell the difference. It really helps keep the dust down!

Powermatic PM1250 Dust Filter
Everything as advertised. Very quite and efficient. I've mounted it on a rolling table to move it around the shop to where I'm working. Would highly recommend. I have a ceiling mounted air filter that is very loud so I don't use it as much as I should. The quiet operation of this sold me on it.

Great dust collector
This is super dust collector but it is bigger than I expected. Wish it was about half the size for better portability and use in my small shop.

I have a split unit AC/heater for my workshop. This filter system will help keep the filter in the air handler cleaner. I also spray a lot of paint which this filter system hopefully will help with keeping paint powder down.

What percentage of particles does it filter at 0.3 µm? In other words is it equivalent to a HEPA filter? What percentage does it filter at 0.1 microns?
BBM on Dec 8, 2018
Does this emit ozone?
BBM on Dec 7, 2018
BEST ANSWER: The same rep that told me the filter efficiency numbers I posted above, claimed that it does not emit ozone but from my understanding that’s not possible. The manual says it has an anion generator, and even the best of those emit some ozone. Maybe not enough to matter in the 680 square foot garage they reference, but it’s still some ozone. So, I’m really not sure how the rep can claim it doesn’t produce any (Of course he also told me that it worked by using a HEPA filter and then gave me their filter efficiency numbers which were nowhere near HEPA standards, so I don’t know how reliable any of his information was).
Why does the model include "1250" in the name when cfm isn't anywhere near 1250cfm? This seems to be misleading when most other air filters in the industry including other Powermatic models approximate the cfm in model number.

Can it replace other air filter system or is it an added system?
Raymond S on Dec 18, 2018
BEST ANSWER: Yes it can replace other air filtration systems. If you have the room in your shop adding this to your existing unit will only help.
