Hi, I'm new to this community. I'm having a problem: My inhome DeVilbiss O2 Concentrator makes a lot of noise (45 dB) so I operate it in my living room at night and in my bedroom closet during the day. The tubing runs along the floor which is hardwood over concrete with a thin layer of insulation between. The insulation is not sufficient to prevent the floor being very cold year round. When I use a humidifier, the tubing fills with condensation so I am breathing cold, dry air all night and occasionally during the day when I need supplemental O2 to support my workouts and strenuous physical activity. My lungs and sinuses are stressed and I wake up with nasal congestion, dry mouth, and a dry hacking cough. My COPD has progressed rapidly since I started using the equipment prescribed to improve my quality of life. My question is simple: is there a device that will warm the air, and allow the moisture to reach me rather than concentrate in the tubing?
