A Winix letter is a shorthand family name, not enough information to order a filter. Keep the numeric reference beside it: Filter A is 115115, Filter H is 116130, and Filter S is 1712-0096-00.
The component format also varies. Some products contain separate HEPA and carbon pieces; Filter O and Filter R are all-in-one canisters with multiple layers.

Read the component format before cleaning or replacing
Filter H contains a HEPA filter and an AOC carbon filter; Winix describes the AOC carbon component as washable, not the HEPA component. Filter A and Filter S include HEPA plus carbon-sheet quantities documented on their records.
Filter O and Filter R are all-in-one canisters. Their pre-filter, HEPA and carbon layers form one model-specific assembly rather than three separately approved replacement products.
