Verdict: The cartridge vs bag shop vacuum choice is simple: choose the Shop-Vac 9030433 cartridge if your vacuum is 5 gallons or bigger and you want a pleated element you swap out. Choose the Shop-Vac cloth bag if you run a small dry vacuum and want a washable, reusable bag that traps fine dust. The IN VACUUM 2-pack shows the cartridge side’s budget angle: a reusable cartridge for 4-gallon-and-smaller vacuums with a brush in the box.
A shop vacuum is only as good as what it breathes through. When the filter clogs, suction dies, and the choice between a pleated cartridge and a cloth bag decides how often you clean, what you catch, and what it costs to keep running. That is what cartridge vs bag shop vacuum comes down to: two filter philosophies for the same wet/dry vacuum, each with honest trade-offs. The three listings below give you one of each side plus a budget cartridge, and the comparison is built on what those listings actually state.

Side by side: cartridge vs bag shop vacuum
| Filter | Side | Type | Size | Standout |
|---|---|---|---|---|
| Shop-Vac Bag 2-Pack | Bag | Non-woven cloth, reusable | 7 in x 6-1/4 in x 3-1/2 in | Washable, 1-year warranty |
| Shop-Vac Cartridge | Cartridge | Pleated paper, disposable | 8 in dia x 6.5 in H | Fits most 5-gal vacuums |

Example figures are manufacturer rated, collected 22 October 2026. A figure from one listing describes that listing only: the Shop-Vac cartridge example fits 5-gallon-and-bigger vacuums, while the IN VACUUM cartridge example fits 4-gallon-and-smaller ones.
How a cartridge filter works
A cartridge is a pleated cylinder that sits over the vacuum’s cage. The Shop-Vac 9030433 example is a 1-layer pleated paper filter: the pleats give the air more surface area than a flat sleeve, which the listing says improves airflow and reduces clogging to capture dirt better than sleeves and bags. It is a replacement for most 5-gallon vacuums, and the listing says to replace it at least twice a year with average use. At 12.8 ounces it adds little weight, and it carries a 1 year warranty.
The IN VACUUM example shows the other end of the cartridge market: a 2-pack replacement for the Shop-Vac 90398, sized for 4-gallon-and-smaller vacuums, marked reusable, with a cleaning brush in the box and a recommended replacement every 2 to 4 months. Two cartridges for the price of one changes the running cost, but the listing states no warranty term, and the fit list is a long string of Shop-Vac model numbers to check before ordering.
Match the cartridge to the tank: the Shop-Vac 9030433 fits 5-gallon-and-bigger vacuums while the IN VACUUM fits 4-gallon-and-smaller models, so the two cartridges do not compete for the same vacuum. The 9030433 is disposable with a twice-a-year cadence and a 1-year warranty; the IN VACUUM is marked reusable, comes as a 2-pack with a cleaning brush, and suggests replacement every 2 to 4 months. If the vacuum runs daily, the 2-pack with a brush is the lower-hassle pick; for occasional use, the single disposable cartridge with a warranty is simpler.
How a bag filter works
A bag hangs inside the drum and catches debris before it reaches the motor filter. The Shop-Vac cloth bag example is a non-woven 2-pack for small dry vacuums, and its selling point is reuse: remove it, shake off the debris, rinse with water, and put it back. The listing says it traps fine particles while holding strong airflow, and the non-woven fabric resists tearing and clogging. It fits Shop-Vac models 5430151, 5430523, 5430112, 5430095 and bucket head 5430093, with a 3-1/2 inch opening, and it carries a 1-year warranty.
The bag’s weakness is capacity and wet work: a bag fills faster than a pleated cartridge on big dry cleanups, and the listing positions it for dry vacuuming, household dust, dirt and sawdust. For a small garage vacuum that mostly sees dry messes, though, a washable bag you never have to rebuy is a strong argument.
Measure before ordering the bags: the title lists 7 x 6-1/4 x 3-1/2 in with a 3-1/2 inch non-stretchable opening, and the listing says to confirm dimensions before purchase. The fit list names five Shop-Vac models plus the bucket head 5430093; anything outside that list is a guess. The 2-pack means one bag can dry while the other works, which matters because the listing says to let the bag dry fully before reinstalling.

Frequently Asked Questions
Can I use a cartridge and a bag together?
The listings here treat them as alternatives, not companions: each example is a replacement for one filter position. Some vacuums accept a bag over the cage plus a cartridge, but none of these three listings states that setup. Check your vacuum’s manual before stacking filters, since doubling up can choke airflow.
How often should I replace a cartridge filter?
Follow the listing. The Shop-Vac 9030433 says at least twice a year with average use, and the IN VACUUM says every 2 to 4 months. A shop that vacuums daily will go through cartridges faster than a garage that sees weekend use. When suction drops and tapping the pleats clean no longer restores it, the cartridge is done.
Are the Shop-Vac cloth bags really washable?
The listing says so: remove the bag, shake off debris, rinse with water, and reuse. Let it dry fully before reinstalling, since a damp bag on a running vacuum breeds odor. The 2-pack means one bag can dry while the other works.
Which side is cheaper to run?
The listings do not state prices, so judge by replacement habit. The Shop-Vac cartridge is disposable with a twice-a-year replacement cadence, the IN VACUUM is a reusable 2-pack with a 2 to 4 month cadence, and the cloth bags are washable and reusable indefinitely. A reusable filter you maintain beats a disposable one you replace, as long as you actually maintain it.
Do these fit my Shop-Vac?
Match the model numbers. The 9030433 cartridge fits Shop-Vac wet/dry vacuums of 5 gallons and above, the IN VACUUM fits 4-gallon-and-smaller models on its long compatibility list, and the cloth bags fit models 5430151, 5430523, 5430112, 5430095 and bucket head 5430093. When in doubt, measure the old filter: the bags are 7 in x 6-1/4 in x 3-1/2 in per the title.
