I have been using the AEIOMed Headrest nasal pillows. Exclusively a side sleeper. Sometimes the seal will break after a couple months use...but a simple rubber band in the right spot increases the tension.

I use an Aura Headrest with nasal pillows

Humidifier condensation collects in my nasal pillows, and when turning onto my back while sleeping. the condensation leaks into my nose and throat awakening me. How can I eliminate the condensation?
