Exact model stated by the manufacturer

WINIX 9800 replacement filter

Documented OEM reference: Filter A · SKU 115115; separate Filter A +AllergenGuard set · SKU 1712-0004-10

The 9800 manual names Filter A / SKU 115115. WINIX separately lists a Filter A +AllergenGuard annual set, SKU 1712-0004-10, as compatible with 9800. This is a separate product/set identifier, not an alias for or proof of equivalence to SKU 115115.

Limits. US-source evidence only; no Canada or UK fitment or availability is established. The annual-set page supports only its own distinct SKU. Do not merge the two identifiers. Aftermarket fit and performance are untested.
