definatly.. because you have to realize that that cfm rating is based on unrestricted suction and the can filter WILL restrict suction.. Im using an el cheapo 400cfm (or so they say) fan suckin on that 2600 filter and I can tell that it cant be more than 100cfm comin thru.. when I had the fan sitting on a table and fired it up It almost propelled itself across the freaken table.. attached to the filter it is much more reasonable.. buy a fan that well exceeds the rating of the filter.. unless its a really good fan like the can fans and then only exceed by about 25-50% I think it is.

Somewhere I heard it works better to suck thru the filter than blow thru it.. but Im not sure.. could be.. I know the dust sock is on the outside.. my plan was to turn the $25 fan I got whichever way worked best (which i figured was gunna be blow thru) and it turned out that it sucked thru just fine.

Seems good, but I am not clear on a couple of things as I have never had to use one, hence never seen one!

I assume the carbon fills the gap between the two. If this is the case, is the poly fill being put into the very center core (from end to end) or is it with Rating: 5
