For some shredders, it's all about security, security, security. This is precisely why we like the HSM 105.3 L5. The "L5" part of the model number lets you know that this model is shredding to "Level 5" security standards (now P-6). Although this isn't the highest level of security and still cannot destroy top secret documents to approved specifications, it is incredibly high for unclassified shredding. Level 3 / P-4 is the most popular shred size we offer, but a growing number of business want extra protection. The 105.3 by HSM is a good choice if your looking for this level of security for a small office. It's small size makes it ideal to fit under or beside a desk. Keep in mind that the added security means that the shredding capacity is only 5-6 sheets at one time . It turns each sheet into over 7,000 confetti sized particles and its even powerful enough to handle staples. We would recommend this for a high level executive or a home office where there isn't a heavy volume of paper that needs to be shred, but the data to be destroyed needs to be completely secure to commercial standards. HSM is known for its quality and has built its entire reputation on shredders that perform. The 105.3 shredder is part of HSM's "Classic" line which was first introduced in 1987 and feature extremely high quality components as well as user friendly features, but, most importantly they do what shredders do best"" shred.
