A common reason for the failure of a double-glazed device is when the desiccant within the unit becomes saturated.  misted double glazed units cost  is designed to absorb excess moisture, and prevent it from making its way into the gaps between the glass panes. However, once it is saturated, the desiccant will lose its capacity to absorb water, and eventually, the moisture between the glass will increase, causing the mist that is commonly observed.

This is common in bathrooms and in kitchens where there is a significant amount of humidity.
