Where is my model number?

Before you buy

  • Pure/Essential, Fresh/Advanced and Odor/Ultimate are different filter choices; this record selects B7-Pure.
  • Keep 75i distinct from 45i and 35i.
  • These manufacturer-listed US model codes do not approve another regional variant. The Amazon action is a reference search, without an approved product, seller or pack.

  2. Match the label with one of the manufacturer-listed US codes on this page.
  3. Compare B7-Pure, components and quantity on the final merchant listing; the search does not approve the listed item or pack.
