Air Filtration system?

[njschaben]

Is anyone using an air filtration system like the Jet AFS-1000B? I have a 30 x 30 shop with a 4x8 plasma table with a water table. Even with the water table I still have some plasma dust while cutting for a long period of time. Also while doing a lot of grinding dust builds up in the shop. Since it is now only getting into the 30's for a high temp I don't want to open up the shop anymore, so I am looking for some thing to filter the air inside so I don't loose all my heat. Everyone seems to like the jet filter system in all the reviews but it seems they are all wood workers. I am not sure if this type of filter system will work for plasma and grinding dust? Any thoughts or ideas would be appreciated. Thanks

I have a shop the same size as yours with a system like you posted. I have a 4 x 4 plasma table with a water table, this filter couldn't keep up when I was doing alot of cutting. It worked fine for grinding and welding dust. It doesn't take long for the filter to get dirty. I bought my system @ Menards and it was $199, but that was 2 years ago.
