I discovered that Lowes sells a Kobalt brand dust bag with the same capacity (5 gallons). It fits the intake port which is 2.5"

I originally bought the Ridgid brand dust bags (VF3501) but they are only 4-4.5 gallons. http://www.amazon.com/dp/B000U5U0OG/?tag=atomicindus08-20
Summary: Kobalt dust bags 3 for $10, only medium filtration, but better fit.
Ridgid dust bag (VF3501), 2 for $12, smaller capacity, but rated for higher filtration.
