A paper shredder is loud by design: a motor driving steel cutters through a stack of paper. That makes it one of the few home office machines where a published noise figure would really help. We checked what the makers publish, and the brand you would expect to lead publishes nothing.
We read product pages, stores and manuals for twenty shredders from five brands, twelve cross cut and eight micro cut, including one auto feed unit.
Our 7 picks are listed above, with full specifications for each.
The quiet brand has no number
Fellowes markets several shredders on quiet operation and trademarks SilentShred to do it. Its product pages carry a noise technology tag, SilentShred or QuietOperation, and no decibel figure. Eight current Fellowes manuals we checked have no dB line either. The only Fellowes noise figures we could find on a Fellowes domain are in a manual for the Powershred 480, dated 2005.
We are not saying a Fellowes shredder is loud. We are saying that the maker most associated with quiet shredding has not, on any current page we could find, put a number on it. This site ranks what makers publish, so Fellowes is absent from the table for the same reason Theragun is absent from our massage gun guide.
Idle is the wrong condition
HSM is the only maker here that labels its figure at all, and the label is "idle operation": "ca. 57 dB(A)" for the shredstar X12 and X20, "ca. 58 dB(A)" for the X10 and X6pro.
Idle is the machine running with nothing in it. It is the quietest state a shredder has, and it is the one state you never buy a shredder for. So HSM leads this guide on the number and on disclosure, and the disclosure tells you the number describes the wrong moment.
Nobody else labels the condition. Bonsaii prints "Noise: 58dB". Amazon Basics prints "Audible Noise 65 db". GBC prints "operates below 58 dB". Aurora prints "58-60 dB". None says whether the machine was shredding, how much, or from how far away. For the general problem, see why you cannot compare dB ratings across brands.
One number for a whole range
Every current Bonsaii EverShred Pro model, from the 5 sheet unit to the 18 sheet unit, is listed at "58dB" on bonsaii.com. A 5 sheet motor and an 18 sheet motor producing an identical figure is not impossible, but it reads as a series claim, not a measurement of each machine.
GBC does something similar: its SX15-06 page says "operates below 58 dB" in the model text and "operating below 62 dBA" in the generic feature blurb further down the same page.
And Bonsaii disagrees with itself across its two sites. The C169-B is "58 dB" on bonsaii.com and "60dB low-noise operation" on bonsaiishop.com, where the same machine also gains a sheet, a security level, ten minutes of run time and half a gallon of bin.
Run time is the other half of quiet
A shredder that has stopped to cool down makes no noise, which is not what anyone means by quiet. The run times published here vary more than the decibels do.
GBC's PX10-06 and PSX10-06 publish a "6 minute run time". The Amazon Basics 18 sheet publishes "30 minutes on / 10 minutes off". The GBC SX15-06 publishes 120 minutes, the SX20-08 240 minutes, and Bonsaii's 4S30 claims "4 hours". If you shred in batches, the run time will shape your afternoon more than a 2 dB difference will.
Where we could not go
Royal publishes prices across eleven shredder pages and no noise figure on any of them. Boxis publishes no specifications on its own site and links to Amazon instead. WORKPRO's site lists no shredders. Swingline's shredder pages now return errors, its range having been folded into GBC. Rexel is not sold in the US.
The whole GBC home range was out of stock or backordered on gbc.com when we checked, which matters for a guide whose readers mostly buy on Amazon.
We did not measure any of these shredders. Every figure here is the maker's own, quoted as published, with the condition attached in the one case where the maker attached one.
