What is a built in humidifier?
A built in humidifier is designed so that it is part of the CPAP machine and cannot be removed or separated from the CPAP machine. This is similar to an all-in-one unit eliminating the need for a second hose or second power cord. Usually the water chamber can be removed for cleaning or replacement purposes. The advantage of a built in humidifier is a more compact unit that uses fewer parts. This design also helps to ensure therapy effectiveness by including the heated humidifier which may provide comfort to the CPAP user they may not have received otherwise. A disadvantage is that they may produce less moisture if used as passover humidifiers because the surface area is typically smaller. Also, since the humidifier is built in to the machine, the ability to detach the humidifier is not an option. This can be an issue for frequent travelers. Lastly, if the machine or humidifier stops working, the entire unit must be sent in for repair or replaced, not just the component that failed.
