## What reviewers say

Two whitelisted hands-on testers (Tom's Guide, TechRadar) reviewed the Blueair Blue Signature and both rate it highly for its furniture-like looks, quiet running and fast odor removal. Both note it lacks any VOC sensor. Tom's Guide additionally measured low, efficient power draw; TechRadar separately flagged that the tabletop scratches easily and the optional wood/chrome bases are overpriced. (Based on 2 reviews, 2 lab-tested, 2025-07-23–2025-10-19.)

Praised: Furniture-like design that blends into a room; Quiet operation; Strong, fast odor removal; Low, efficient power consumption.
Flagged: No VOC (volatile organic compound) sensor; Optional wood/chrome bases are overpriced ($80-$100); Tabletop surface scratches easily; No germ-killing capability.
Disagreement: No verdict conflict - both testers are broadly positive. The only cross-source gap is measured top-speed noise: Tom's Guide recorded 58.5 dBA (at 36 in) versus TechRadar's 55 dB, reflecting different test distances/methods rather than a genuine dispute.
