Buying a Dust Extractor - Festool or another?

[six-point socket II]

Since the subject is of general interest to me, I did some further research. Hilti is a bit more talkative about their "Dust research center" and the overall procedure:

Kind regards,

TNO has also more on their procedures:http://www.dustfreeworking.tno.nl/dynamics/modules/SFIL0100/view.php?fil_Id=487

Quite interesting.

Kind regards,

Definitely seems a lot more serious than any YT vid I've seen

my CT26 has been well used in the last 6 years-lots of concrete dust, sanding dust and of course sawdust.  I learned the cheap knockoff bags don't compare to the more costly Festool bags, good for thick stuff like ripping but not concrete surfacing (tile prep work). 

it's been a solid workhorse.  yes, a little heavy hauling up stairs but replace the bags when it's getting heavy or buy a CT-SYS for small jobs.  it's been a nice addition for me.
