01
The letter and numeric reference travel together
Published examples include Filter A / 115115, Filter H / 116130, Filter S / 1712-0096-00 and Filter Q / 1712-0123-00. The letter alone does not establish pack contents or fit.

D3 and D4 are separate D-series references
D360 maps to Filter D3 / 1712-0101-02. D480 maps to Filter D4 / 1712-0100-02. A shared D prefix does not make the two sets interchangeable.

O and R are all-in-one canisters
Filter O / 1712-0110-00 and Filter R / 1712-0118-00 combine pre-filter, HEPA and carbon layers in model-specific canisters. Their layers are not separate approved replacement items.
