Frequently Asked Questions
Is P-4 secure enough for personal and financial records?
For ordinary business use, yes. P-4 is the level most organisations specify for material carrying names, addresses, account numbers and health or payroll details. Each sheet is reduced to 4 x 25 mm particles, an area of 100 mm2, and DIN allows up to 160 mm2 at this level. It is not a level intended for classified or trade-secret material - that starts at P-5 and above, which this machine does not offer.
Can it shred staples and paper clips?
Yes. HSM states the hardened steel cutting rollers cope with staples and paper clips, so you do not need to strip documents before shredding. That is genuinely useful on a five-sheet machine, because de-stapling is a bigger time cost than shredding at this size. Bulldog clips, ring binders and laminated sheets are a different matter and should be removed.
Does it shred credit cards or CDs?
Credit cards yes, CDs no. The Pure 120 carries a T-4 rating for magnetic data carriers, which covers bank and loyalty cards, and HSM lists cards among its shreddable materials. It carries no O rating, meaning optical media is outside its specification - feeding a CD into it risks the cutting head. If you need to destroy discs, the Pure 320 strip-cut or either Pure 420 is rated for optical media.
Will legal-size paper fit?
Yes. The throat is 225 mm wide, which is 8.9 inches, so US letter and legal both feed in portrait - legal is longer, not wider. A4 at 210 mm also fits. Tabloid at 11 x 17 inches does not: 11 inches is 279 mm, well over the opening. If tabloid or A3 is part of your workload, the HSM Pure 530 with its 300 mm throat is the only machine in this series that takes it unfolded.
How often will I be emptying the bin?
HSM rates the 20 litre container at roughly 184 shredded sheets. At a realistic desk-side rate of thirty or forty sheets a day, that is emptying about once a week. If your figure is closer to a hundred sheets a day you will be emptying it daily, which is the point at which the 25 litre Pure 220 or the 35 litre Pure 420 starts paying for itself in walked steps.
Can two or three people share it?
Not comfortably. HSM does not publish a duty-cycle rating for the Pure 120, and at five to six sheets a pass with a 20 litre bin it is specified as a personal machine. A queue forms quickly. As a rule of thumb, one regular user is fine, two is tolerable if neither shreds much, and beyond that you want the Pure 420 or Pure 530, which are built around a shared workflow.
Is this shredder NSA approved?
No. NSA/CSS 02-01 listing requires a maximum particle size of 1 mm x 5 mm and the specific model appearing on the NSA Evaluated Products List. The Pure 120 cuts 4 x 25 mm, roughly twenty times that area, and is not on the list. If you have a genuine classified-destruction requirement, you need a high-security P-7 machine that is individually NSA-listed, and we can point you to the models that qualify.
