The noise levels are impressively low at 24 decibels on the quietest setting, making it suitable for bedrooms or offices where minimal disruption is desired. The display lights can be turned off at night for added comfort. Maintenance involves washing the pre-filter and replacing the main filter every 6 to 8 months depending on usage.
