Coway uses several pack structures across the Airmega range. The purifier model decides both the filter reference and whether the manufacturer product contains one combined filter, two side filters, or separate HEPA and deodorization components.
Start with the exact Airmega or AP number. Fresh Starter+, Max2 and a Mighty replacement set are product descriptions, not interchangeable Coway families.
Reference and box-structure map
The table describes the retained manufacturer product. A merchant can sell a different quantity, so compare the final listing before ordering.
| Purifier | Reference | Manufacturer product structure |
|---|---|---|
| Airmega 100 | 826439000820 | One Fresh Starter filter with documented layers. |
| Airmega 230 / 240 | 826439000592 | One combined Max2 filter. |
| Airmega 250 / 250S / 250ART | AP-1720-FP | One Max2 filter in the retained option. |
| Airmega 300 / 300S | AP-1515-FP | Two Max2 filters, one per side. |
| Airmega 350 | 826439001216 | One Fresh Starter+ filter. |
| Airmega 400 / 400S | AP-2015-FP | Two Max2 filters, one per side. |
| Airmega 450 | 826439001223 | One Fresh Starter+ filter. |

Do not confuse layers with separate replacements
A combined Max2 or Fresh Starter product can contain several filtration layers in one assembly. The Mighty/200M record instead documents separate HEPA and deodorization pieces in the set.
For the Mighty/200M system, retain and clean the reusable pre-filter according to the purifier instructions. It is not included in the documented 3304899 replacement set.
AP-1512HH: check the serial block as well as the model
For AP-1512HH / AP-1512HH(W), Coway checks the five-character block immediately after the serial number’s first three characters. Its listed blocks for the 200M & AP-1512HH set are 02E90, 02FI6 and 02EMY.
If the block differs, do not select this set by the AP-1512HH name alone: Coway rejects its different-block example. AP-1512HHS is a separate model. These serial examples concern AP-1512HH / AP-1512HH(W), not a new serial requirement for 200M.
