Choose the Fellowes 99Ci for longer shredding sessions and a larger bin; choose the 79Ci if 16 sheets per pass and a smaller bin fit your routine. Both are P-4 cross-cut shredders with SafeSense protection and jam-proof features.

The 99Ci handles up to 18 sheets per pass and runs for up to 30 minutes, while the 79Ci handles up to 16 sheets and runs for up to 20 minutes. Both have pull-out bins with LED bin-full indicators.

Both models can also shred staples, credit cards, paper clips, CDs/DVDs and junk mail. Their shared features and different capacities make the 99Ci vs 79Ci comparison a choice about workload, session length and bin size.

Fellowes 99Ci vs 79Ci: what is the main difference?

The 99Ci takes 2 more sheets per pass, runs up to 10 minutes longer and has a bin that holds 3 more gallons. Those differences can suit you if you regularly shred larger paper batches.

The 79Ci shares the same P-4 cut size and SafeSense feature. If your shredding jobs are brief, its lower capacity may be enough, and the 6-gallon bin may suit your needs.

Which shredder handles a larger workload?

The 99Ci suits larger batches because it takes more sheets per pass and has a longer run time. That can reduce interruptions when several people share a shredder or paperwork builds up between sessions.

Its 18-sheet capacity is 2 sheets higher than the 79Ci’s. Both figures refer to the maximum sheets per pass, so follow the instructions for your machine and avoid forcing paper through.

The 99Ci’s maximum run time is 30 minutes, compared with 20 minutes for the 79Ci. These are stated limits before a cool-down period.

When does the 99Ci’s extra capacity matter?

The difference matters when you often shred full stacks or clear paper for more than one person. Its longer run time and higher sheet capacity give you more room for a busy session.

For a few documents at a time, you may not notice much benefit. Think about your typical weekly batch, not only the largest one you might shred once a year.

Can the 79Ci handle a shared office?

The 79Ci can suit a shared workspace with moderate batches. It handles up to 16 sheets per pass and is described for home offices and businesses.

Its 20-minute run time is shorter than the 99Ci’s, so consider how often people need to shred and whether they can take turns. For frequent larger batches, the 99Ci has more headroom.

For a broader look at Fellowes models, see our guide to the best Fellowes paper shredders. It compares these two with models built for different workloads.

Do the 99Ci and 79Ci offer the same security?

Yes, both are P-4 cross-cut shredders with the same stated particle dimensions. Each cuts paper into 397 particles measuring 5/32 x 1-1/2 inches.

That shared cut specification means the 99Ci’s larger capacity does not come with a different stated security level. If you want a plain-language explanation of cross-cut shredding, read what a cross-cut shredder is.

P-4 is a useful point of comparison, but choose a shredder based on the documents you handle and any rules that apply to your workplace. For sensitive records, follow your organization’s disposal policy.

How do bin size and placement compare?

The 99Ci has a 9-gallon bin, while the 79Ci has a 6-gallon bin. A bigger bin can mean fewer emptying trips, while a smaller one may work well if you shred less at a time.

Both have pull-out bins with LED bin-full indicators. Check the space where the shredder will stand, including room to open and remove the bin.

The 99Ci measures 17.31 in deep, 11.44 in wide and 25.19 in high. The 79Ci measures 10.25 in deep, 15.2 in wide and 21.1 in high.

Bin capacity and outside dimensions describe different things. Measure the placement area before choosing, and leave working room to use the pull-out bin.

What features do both Fellowes shredders share?

Both models have SafeSense, jam-proof features, quiet-operation claims and the same list of supported materials. SafeSense disables shredding when hands or paws touch the paper opening.

The 99Ci and 79Ci can shred paper, staples, credit cards, paper clips, CDs/DVDs and junk mail. Follow each model’s instructions for feeding non-paper items and keep fingers and paws away from the opening.

Both are described for shared workspaces and as able to detect and power through tough jobs to prevent jams. Feed material within the stated sheet capacity and follow the operating guidance.

How often will each one need a cool-down?

The 99Ci runs for up to 30 minutes, compared with up to 20 minutes for the 79Ci. Actual work sessions depend on the amount and type of material you feed and how you use the machine.

A longer run time helps when you want to process a stack in one sitting. It matters less if you shred a few documents after opening mail or finishing a task.

Both machines need a cool-down after reaching their stated run time. Our guide to paper shredder run time and cool-downs explains how to plan sessions and reduce avoidable stops.

Is there a smaller Fellowes alternative?

The Fellowes 14C10 handles up to 14 sheets per pass, runs for up to 10 minutes and has a 5-gallon bin. It also makes P-4 cross-cut particles, but its stated session length is shorter than either Ci model.

The 14C10 has a Safety Lock that disables the shredder as needed. The 99Ci and 79Ci have SafeSense, which responds when hands or paws touch the paper opening.

If you shred regularly or need a longer session, the two Ci models offer more capacity. For light personal use, the 14C10 may be enough.

Which Fellowes shredder should you choose?

Pick the 99Ci for higher capacity, longer sessions and a larger bin; pick the 79Ci for moderate batches where its 16-sheet limit and 6-gallon bin are sufficient. Both share P-4 cross-cut shredding and SafeSense.

Choose the 14C10 if a 14-sheet capacity and 10-minute run time match your smaller jobs. For more help sizing a machine to your needs, use our paper shredder buying guide.

Can the Fellowes 99Ci and 79Ci shred credit cards and staples?

Both models can shred credit cards and staples, as well as paper clips, CDs/DVDs and junk mail. Follow the instructions for loading non-paper items and any limits on what you feed, and don't assume every item should go through in the same batch.
