Before you buy
- This record covers Filter O for A230, A231 and T500. Other Winix A-series or T-series codes are not approved by a similar name or shape.
- These manufacturer-listed models were checked for the US. An international Amazon search does not approve another regional model or filter variant.
- The Amazon action is a reference search. No exact retail product, seller or pack has been approved; check the manufacturer name, printed reference and required components on the final listing.
Find the complete model code
- Read the complete Winix model on the purifier label and keep every letter, digit and suffix.
- Match your label with one of the manufacturer-listed models on this page.
- Compare 1712-0110-00 and the listed components with the final merchant item; a search result alone does not establish identity or pack contents.
Filter and fitting details
- Manufacturer pack: one all-in-one canister combining a fine-mesh pre-filter, HEPA layer and activated-carbon layer. The layers are parts of the canister, not three separately approved retail filters.
- The current manufacturer product page explicitly lists A230, A231 and T500. Its product reference is 1712-0110-00.
- Confirm the complete reference and canister format on any merchant listing. Similar cylindrical filters do not establish another model relationship.
