Thread: Room cleaner air filters - are they any good?

Take some photos of the old DCs and post them here for more advice.

Yes Bob, you are right. They have cloth bags for both collection and filtration. My intention is tu use plastic bag and a pleated filter. I'm more concerned about the motor.
Here is some pictures. They guy has more than one so I just need to pick the best one I guess

I'd buy the newest one (or the one with the least vibration, or quietest one) and replace the bags as described.

FWIW I use a mobile app to measure vibration because it is far more sensitively than the human hand etc.
The one I use cost $ but there may be free ones out there I just haven't looked for some time.
They may take a bit of getting used to using.
