Filter slot: Xiaomi Mi Air Purifier 3-family barrel¶
Provenance: Inferred
Status: unmeasured
Cylindrical "barrel" cartridge format that spans the Mi Air Purifier 2, 2S, 2H, 3, 3H, 3C, Pro, and Pro H units. Xiaomi publishes three interchangeable media variants in the same housing (M8R-FLH original / HEPA, M8R-FLG antibacterial, M8R-FLP anti-formaldehyde) which is strong evidence the slot geometry is shared within this generation. The Mi 4 family appears to use a similar but distinct cartridge; treat as a separate slot until measured. Aftermarket sellers tag this slot with handle / unit model names (3H, 3C, Pro) more than the filter SKU.
Notes¶
Mi Air Purifier 3C (AC-M14-SC) is the budget variant of the 3-generation line: smaller CADR, no PM2.5 display, but the same cylindrical filter cartridge as the 3 and 3H. Xiaomi's filter store page cross-lists the M8R series as compatible with 3 / 3H / 3C / Pro / Pro H, which is the primary evidence that 3H and 3C share the slot. Aftermarket listings on AliExpress mostly tag this cluster by the unit model name (3H, 3C, Pro) rather than by the filter SKU.
