The original Molekule Air and the later Mini and Pro models do not share one replacement structure. Original Air keeps a separate pre-filter; Mini/Mini+ and Pro use integrated model-specific filter assemblies.
PECO, HEPA and carbon in a Tri-Power description identify elements within the replacement filter. They are not three separately approved merchant cartridges.
Three purifier records, three product identities
Choose by purifier name before comparing subscription or quantity options.
| Purifier | Replacement product | Components |
|---|---|---|
| Original Air | Air Filter Pack | One PECO filter plus two separate pre-filters. |
| Air Mini / Air Mini+ | Air Mini / Mini+ PECO-HEPA Tri-Power Filter | One integrated model-specific filter. |
| Air Pro | Air Pro PECO-HEPA Tri-Power filter | One integrated model-specific filter. |
Quantity and subscription do not create another filter family
Manufacturer pages can offer multiple quantities or recurring shipments. Those choices change how many filters arrive or when they ship; they do not extend compatibility between Air, Air Mini and Air Pro.
Confirm the complete product name after any retailer redirect. A search result containing PECO or Tri-Power is not enough without the purifier name.
