What will happen if the HumidX is used well over 30 days?

AirMini / Humidification

If the HumidX is used beyond 30 days this can cause deterioration in cleanliness, humidification performance and breathing comfort which can affect safe and efficacious use of AirMini. Ensure the HumidX and other components of the AirMini system are regularly maintained as per the user instructions.
