Why is Kaiyou atomizer so expensive?

Kaiyou atomizer is so expensive for the following reasons:

1, the average drug inhalation is high, and the average drug inhalation dose delivered by compression atomizer is two or three times as much as that delivered by ultrasonic atomizer.

2. It has no influence on the temperature of atomized medicine. Ultrasonic atomization of drugs increased by 20 degrees Celsius during the operation, while compression atomization of drugs had no obvious temperature change.
