Are Alpine Air Living purifiers silent in operation?
Yes, all Alpine Air Living purifiers are very quiet at normal settings. The only exception is, if you need to really sanitize a particular area of your home or office (for example, to reduce mold or mildew, or very heavy particulate contamination in the air). In this case, you will need to turn the fan and purifier control on very high setting, and you will hear the unit operate. However, after sanitizing you will return the unit to its normal settings, at which the unit operates very quietly.
