CADR — Clean Air Delivery Rate (dual-sourced)
435 cfm smoke · 452 dust · 450 pollen (Blueair-stated) (source conflict noted)
- Blueair product page: “Clean air delivery rate (CADR): Pollen 450 cfm <br> Dust 452 cfm <br> Smoke 435 cfm”
- SmartHouseGears review: “With a CADR of about 410 CFM for smoke, dust, and pollen, its real sweet spot is roughly 615 sq ft at nearly five air changes per hour under AHAM's two-thirds rule.”
Conflict note: Blueair's product page spec table lists Pollen 450 / Dust 452 / Smoke 435 cfm (verified live 2026-08-24); SmartHouseGears instead measures a flat ~410 CFM across smoke, dust and pollen without publishing a split. The manufacturer trio is rendered with that independent-review conflict disclosed.
