Air purifiers

Working name: OpenAir. The second category in the Open Consumables device knowledge graph.

What's here

  • Units, the air purifiers themselves, with replacement filters listed by slot.
  • Filters, OEM and generic cartridges, with the units they fit.

Status

Reference layer only. OpenAir is not yet an active measurement subproject; activation depends on OpenBrush producing a published measured baseline. Until then, this category exists as a knowledge-graph stub: provenance-tagged compatibility data sourced from manufacturer pages and aftermarket listings, with no project measurement claims.

Coverage is intentionally small: a Xiaomi 3-family slot (3H, 3C, plus the OEM HEPA / anti-formaldehyde cartridges and a generic clone catch-all) and a Smartmi P1 slot for contrast. Pull requests welcome; see the data README for the schema.

Scope

In scope for the reference layer:

  • consumer Chinese-IoT cluster air purifiers (Xiaomi, Smartmi, Viomi, Roidmi, Deerma, Airdog)
  • the mechanical filter-slot interface between unit and cartridge
  • HEPA grade, media composition, and filter-stage architecture as disclosed by the manufacturer

Out of scope at this stage:

  • particulate-removal performance benchmarks
  • CADR independent verification (manufacturer claims only, until measured)
  • Western-brand purifiers (Dyson, Levoit, Coway, Honeywell): fail the ecosystem-selection prerequisite
  • the purifier motor, controller, sensor calibration, or app integration
