Short answer: choose P-4 for most routine confidential small-business paper when no stricter written requirement applies. Move to P-5 when a contract, internal policy, client expectation, or unusually high consequence calls for smaller particles. If chain of custody, witnessed destruction, or a destruction certificate matters more than convenience, use a vetted shredding service instead of buying a more expensive office machine.
Do not choose from the words cross-cut or micro-cut alone. Verify the actual P-rating, then size the shredder for your paper volume and work pattern.

The Document Risk to P-Level Framework
Cut Type Is Not the Same as Security Level
Marketing terms can blur two separate ideas. Cross-cut and micro-cut describe the cutting approach. The P-rating describes the resulting paper-particle limit under the referenced standard. The current Fellowes documentation identifies the 99Ci as cross-cut P-4 and the LX220 as micro-cut P-4. That means “micro-cut” does not automatically mean P-5.
The practical lane for many confidential business records when policy does not require more. Current office models can be cross-cut or micro-cut.
A smaller-particle lane for higher-sensitivity material or a written requirement that justifies the extra equipment cost and operational tradeoffs.
Use a vetted destruction provider when chain of custody, locked collection, witnessed destruction, volume, or a destruction certificate is the real requirement.
Do U.S. Rules Require P-4 or P-5?
There is no honest universal answer. The FTC Disposal Rule tells covered businesses to take reasonable measures when disposing of consumer report information. HHS guidance similarly requires reasonable safeguards and disposal policies for protected health information. Neither source cited here names one P-level that fits every business.
Your obligation can still be stricter because of a contract, state rule, professional standard, client promise, insurer, regulator, or internal policy. Get that requirement in writing. Do not turn an editorial equipment comparison into a compliance certificate.
Fellowes Powershred 99Ci
Fellowes identifies the 99Ci as a P-4 cross-cut small-office/home-office shredder for one to three users. It is the cleanest starting point when the office handles routine confidential paper, wants a shared machine, and does not have a written P-5 requirement.
Fellowes Powershred LX220
The LX220 is useful precisely because it demonstrates the label problem: Fellowes describes it as micro-cut and P-4. Choose it when you want a current shared-office machine with finer-looking output and the P-4 level fits the written requirement. Do not buy it under the assumption that every micro-cut model is P-5.
Fellowes Powershred 225Mi
Official Fellowes material identifies the 225Mi as a P-5 micro-cut commercial shredder. It belongs in the comparison when the office has a real P-5 reason and enough recurring volume to justify a larger commercial machine. It is not the automatic “best” choice for every confidential document.
Security Level First, Capacity Second
After the P-level is settled, compare users, sheets per pass, continuous runtime, cool-down behavior, bin size, noise, maintenance, staples or cards, warranty, and service access. An office that saves paper for Friday afternoon can need more runtime than one that shreds a few pages at the source each day.
Placement changes compliance behavior too. A secure shred bin beside the scanner or admin station is easier to use than a powerful shredder hidden in a supply room. Decide what happens to paper before shredding, during a jam, and after the bin is emptied.
When Not to Buy a Shredder
Do not buy one just because P-5 sounds safer. A vetted service can be the better fit for large file cleanouts, multiple locations, locked collection consoles, witnessed destruction, formal chain of custody, or destruction certificates. The equipment decision should follow the destruction workflow, not replace it.

P-4 vs P-5 Shredder FAQs
Is P-4 enough for a small business?
P-4 is a practical default for many confidential small-business papers when no stricter written requirement applies. Verify the exact law, contract, client promise, insurer, and internal policy before relying on that general rule.
When should a small business choose P-5?
Choose P-5 when a written requirement calls for it or when unusually sensitive records and the consequence of exposure justify smaller particles. Do not choose it only because the number is higher.
Is every micro-cut shredder P-5?
No. Current Fellowes documentation identifies the LX220 as micro-cut and P-4. Verify the exact P-rating for the exact model.
Is a cross-cut shredder always P-4?
No. Cut style and P-rating are separate properties. The Fellowes 99Ci is one current cross-cut P-4 example, but you must verify each model.
Does HIPAA require a P-5 shredder?
The HHS disposal guidance cited here requires reasonable safeguards and disposal policies; it does not name one universal P-5 machine for every covered entity. Obtain advice for your specific obligations.
Does the FTC Disposal Rule require P-4?
The FTC source cited here requires reasonable disposal measures for covered consumer report information and does not prescribe one universal P-level. A business can still have stricter contractual or policy requirements.
When is a shredding service better than an office shredder?
A service can be better when the real need is locked collection, high volume, multiple sites, witnessed destruction, chain of custody, or a destruction certificate.
