Yes—the Blue Signature air purifier is actively working, even if the improvement in air quality isn't immediately noticeable. The unit continuously monitors airborne particles using its integrated laser particle sensor, which detects levels of PM1.0, PM2.5, and PM10. When in Auto Mode, the fan speed automatically adjusts based on real-time air quality readings to deliver optimal performance without unnecessary noise or energy use.
To ensure you get the best results, follow these expert setup tips:
-
Remove the plastic wrap from the filter before using the air purifier. Operating the unit with the packaging still on will prevent proper filtration.
-
Use in an appropriately sized room—not larger than the recommended capacity of 705 sq. ft.
-
Allow for proper airflow—place the purifier where air can circulate freely around it.
-
Maintain clearance—keep at least 4 inches (10 cm) between the unit and surrounding objects.
-
Close doors and windows while the purifier is operating to prevent new pollutants from entering.
-
Replace the filter when the indicator on the control panel alerts you—this is crucial for maintaining performance.
-
Follow routine maintenance as outlined in your user manual.
With these steps, you can be confident that your Blue Signature purifier is delivering cleaner, healthier air—even if it's working quietly in the background.
