Best value
No cheaper model scores higher.
We line the models up by today’s price. A model gets this label when it scores higher than every cheaper model, so each step up the line buys a higher score. A higher score counts only from 0.5 points (out of 10) above the previous label, so a gap that reads as equal on the page earns no new label.

The maker
Fellowes traces its start to 1917, when Harry Fellowes took over a record storage box and registered the company as The Bankers Box Company. Its corporate headquarters are in Itasca, Illinois, in the United States. The company is still owned and led by the Fellowes family, now in its fourth generation. It widened its brand from paper shredders to areas such as air purification. Its Dutch site says an air purifier with HEPA filtration can remove nearly all (99.95%) airborne particles of 0.3 micron.
