Zach was very helpful and able to describe how I could use the antibacterial filter with my CPAP machine. He knew every answer to my questions. Definitely great customer service at CPAP.com. They’re a great resource to have when my regular CPAP supplier “drops the ball” on getting my supplies to me on time!
