Every Aero Enrichment ultrasonic humidifier and GaN III charger is covered by a 12-month replacement warranty covering the 2.4MHz piezo transducer disc, OLED display module, and GaN power circuitry.

Our ultrasonic humidifiers are engineered strictly for clean tap or distilled H2O. Damage caused by adding viscous botanical extracts or unauthorized chemical additives voids the acoustic disc warranty.
