From a Registered Nurse, infection control standpoint, this device is exceptionally well-designed. The humidifier bottle connection point is secure. I highly recommend this unit for immunosuppressed patients who require long-term oxygen therapy." Rest is medicine, I have struggled to sleep due to noisy medical equipment. This concentrator operates at a remarkably low decibel level, sounding like a gentle ambient fan rather than a medical compressor. The night-mode setting dims the LED display completely, preventing artificial light from disrupting my circadian rhythm. It successfully delivers nocturnal oxygen needs without sacrificing the quality of the my sleep." I will continue to appreciate the price point, on a quality o2 concentrator. Buy with confidence.
