The "Pink Noise" Effect
Many people find dead silence unsettling. The steady, low hum of a quality air purifier fan acts as **Pink Noise**—a frequency that can mask jarring sounds like car doors slamming or foxes screaming outside. Combined with the removal of nasal irritants like dust, this leads to deeper, less interrupted sleep.
Night Mode is Key
Ensure your unit has a "Display Off" function. Even a tiny green power LED can disrupt melatonin production. All the bedroom-ready units we review have this feature.
Summary
Clean air + Sound masking = The perfect sleep environment.
