“If this Blueair purifier is set in automatic, it stays on at all times. Should it be turned off at intervals, or is it ok to keep it running at all times 24/7? Thank you.”

• Thank you for your interest in Blueair! Yes, your Blue Pure 311i Max air purifier can operate 24/7, and in fact, continuous use is recommended — especially when set to Auto mode, which automatically adjusts the fan speed based on real-time air quality. This helps maintain optimal indoor conditions.

• I imagine it is fine, but I use the app to set the night mode. Returns to auto at set time in the morning.
