I have purchase two of these filter for my lasers, and use them on tabletop CO2 and enclosed diode lasers. The filters have worked well for removing the smells of processing various materials and the noise is acceptable for the amount of air that this unit can move on the highest setting.

The units did not contain the same accessories: one unit came with an exhaust hose, the other did not; one unit came with two sizes of hose adapters, the other with three sizes; one unit came with three extra prefilters, and the other with two. I can only state that the second filter I ordered contained the full set of accessories (hose, three adapters and three prefilters), however your purchase may be different.

Even without the full set of accessories, I would still buy another if the size met my requirements.

Just got my airfilter and I must say it exceeds my expectations.
It is a replacement for my diy filter which was not nearly as good as this professional one. If I had known how good it is in comparison to the diy filter, I would have never started building one myself!
Delivery was fast and it was packaged perfectly. Nevertheless the inner filter could only be removed with some effort, because it was damaged at one corner, so it gets stuck and needs a lot of force when trying to remove it.
We removed it, because we could not find a hose as described above and thought that it could only be in the case itself... but nope, no hose delivered. (Could have been really handy to have a 3m one instead my old 1.5m hose.)

But all in all I can recommend this filter and I give it 5 stars.
