Air Purifier & Air Quality Product Sourcing
1 resources tagged with "Air Quality"
Air-quality products from China center on purifiers built around true HEPA H13 filtration and rated by CADR (clean air delivery rate), commonly in the 300–500 m³/h band for room-sized units. The two specs that get gamed are filter grade (H13 vs a marketing 'HEPA-type') and the CADR figure itself, so independent verification matters. For the US market, CARB certification is required for any device that could emit ozone, and CE covers the EU.
Sourcing an air purifier means locking down the actual HEPA filter class (H13 is the meaningful threshold) and a third-party CADR number, then matching certification to market — CARB for California/US, CE for the EU. The pitfall is accepting a supplier's self-reported CADR, which is frequently inflated; we ask for an AHAM or equivalent test report.

FAQ
What does CADR mean when buying an air purifier?
Clean Air Delivery Rate measures how much filtered air a unit produces, usually in m³/h or CFM. Room units commonly fall in the 300–500 m³/h range; higher CADR means faster air cleaning for a given room size.
What certifications does an air purifier need for the US market?
CARB certification is required in the US for devices that may emit ozone, and a UL/ETL safety listing is expected by retailers. CE marking covers the EU.
