Before you buy
- Keep the suffix: Winix 5500 is listed here, while the separate 5500-2 model is manufacturer-listed for Filter H, 116130. Do not drop -2 from a model code.
- 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 115115 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 standard HEPA filter and four activated-carbon sheet filters. These are the manufacturer contents, not an approved Amazon pack.
- The manufacturer explicitly lists 6300, P300, 5300, 5500, 5300-2, 6300-2, AM90, C909, 9800 and C535 for 115115. Other models require their own source.
- The 5300-2 user manual independently identifies Filter A / SKU 115115. Filter A specialty variants have separate product references.
