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

WINIX's Filter A page names C535 for SKU 115115. Its separate Filter A +AllergenGuard page also lists C535 as compatible with set SKU 1712-0004-10. This is a distinct 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. Treat the annual set as a distinct OEM product from Filter A SKU 115115. Aftermarket fit and performance are untested.
