Just wondering I recently purchased a hepa cartridge filter for my shop vac. It does 10x better with the fine dust than the old paper filter. So I feel it does not pollute the air with fine dust (held a tack cloth near the exhaust).
But I still have the noise of the shop vac. My 2 hp DC is much quieter than the shop vac it also has a cartridge filter.
Having never heard the Festool vac / dust extractor, is it worth the purchase price just for the noise reduction??
Another point is I just bought a new shop vac for the house (house use only by the wife). And it is at least 1/3 more quiet than my older vac. Another one would be $100 for the size I want. But considering the Festool. I have no Festool tools though, just my other brands that I connect a hose too. Plus since the old shop vac works just fine for general cleaning really don't need another big shop vac.
So based on noise level is it worth the extra money - just work in shop for fun.
