Intake Filter Shootout
 

I decided to only post thins in here seeing as how none of these kits are offered for the KA and what not, thought the filters can be used. I found this trying to figure out what Intake I wanted:

:headbang2:

the tests didn't use "kits". it was just a filter attached to a shop vac and a pre-determined amount of black substance was sucked through the filter for a set amount of time.

anyone who's ever have a kirby demonstration at there house has seen the same test.
