Our Verdict

Blueair Blue Signature Small

Blueair Blue Signature Mini

As a standalone air purifier, the Blueair Blue Signature Small comfortably outperforms the Blueair Blue Signature Mini. The Small provides more than twice the coverage at its highest fan speed, a gap that narrows only marginally at lower speeds. While the Mini runs quieter and has a smaller footprint, the Small is neither noisy nor particularly bulky.
