Product Information
Full details
The Blueair Blue Signature Medium is designed for homeowners and office users seeking high-performance air purification for mid-to-large spaces up to 86 square meters. Its primary strength lies in its rapid CADR of over 500m/h and advanced 7-stage dual filtration system, which effectively eliminates fine particles and neutralizes odors via bio-based enzymes. While it offers premium air quality control, users should note that its size requires a dedicated floor space and regular filter maintenance to ensure peak performance.

Setup, Compatibility & Care
Setting up the Blueair Blue Signature Medium involves removing the protective packaging from the dual-filter cartridges and positioning the unit on a flat, stable surface. Download the Blueair app to pair the device with your 2.4GHz Wi-Fi network for remote management. For maintenance, vacuum the outer intake mesh once a month to prevent dust buildup. The system will alert you via the mobile app when the filters have reached their capacity, typically every 6 months depending on local air quality. Always unplug the unit before performing any cleaning or filter swaps.
