Shark filter references divide the retained purifier models into three groups. HE1FKPET covers the published HP100 / HC450 group, HE2FKBAS the HP200 / HC500 group, and HE3FKPET the HP300 NeverChange group.
Keep every suffix from the purifier label. HC450C, HP202C, HC502QGY and HC502QWH are complete documented codes, not formatting variants to remove.
Three published filter groups
The family names below summarize the records. Open the model link to check every exact compatible code.
| Reference | Retained family | Important distinction |
|---|---|---|
| HE1FKPET | HP100 / HC450 and listed UA455 codes | Odor Lock filter; other HE1 variants remain separate. |
| HE2FKBAS | HP200 / HC500 and listed UA205 / UA505 codes | Keep QGY, QWH and C suffixes where present. |
| HE3FKPET | HP300 / HP301 / HP302 / HP305 | NeverChange HEPA filter with carbon for this exact group. |
Do not use the NeverChange name as a fit rule
NeverChange is product-family wording. The retained HE3FKPET manufacturer page names HP300, HP301, HP302 and HP305; it does not extend the match to every Shark purifier carrying similar marketing.
Mesh screens, odor-neutralizer accessories and a carbon layer inside a filter can have different care or replacement instructions. Follow the complete model manual rather than treating them as one retail pack.
