Fan-driven appliances with a special US twist: ozone rules in California apply to air cleaners specifically.
Air purifiers are fan appliances under the household-appliance standards, but the US market adds a category-specific gate: California requires air cleaners to be certified by CARB (the state air resources board) with ozone emission limits - and because California is the largest US market, that effectively becomes a national requirement.
Ionizing and electrostatic technologies get the most attention here; HEPA-only designs have an easier ozone story but still need the standard appliance and EMC scope.
| Market | Typical requirements | Notes |
|---|---|---|
| United States | FCC Part 15 Subpart B; CARB certification for air cleaners sold in California (ozone emission limit); retailer listings to UL 867 / UL 507 framework | CARB is state law but practically national - most US retailers ask for the listing |
| European Union | CE: LVD with EN 60335-1 + EN 60335-2-65 (air-cleaning appliances); EMC; RoHS | Ozone-releasing designs need the ozone-relevant clauses of the standard |
| Connected models | RED/FCC ID for WiFi models; EN 18031 (EU) and PSTI (UK) for connected products | App-controlled purifiers are radio products with cybersecurity duties |
| Performance claims | CADR and filter-life claims are marketing statements, not certifications - test reports back them | Buyers increasingly ask for the data behind the claim |
Launching an air purifier in the US or EU? Tell us the technology (HEPA, ionizer, UV) and connectivity - we will scope CARB and safety testing to match.
The California Air Resources Board requires air cleaners sold in California to be certified, with a specific ozone emission limit. Ionizing and electrostatic designs are the main targets. Because retailers apply it chain-wide, it functions as a US-wide gate.
They still face the appliance safety scope and general market requirements, but the ozone story is simpler without ionization. If the product has any ionizing or UV feature, ozone testing belongs in the plan.
It becomes a radio product: FCC ID in the US, RED in the EU, and the connected-product cybersecurity rules (EN 18031 for the EU, PSTI for the UK) join the plan alongside the appliance safety testing.
