When you depend on supplemental oxygen every day, the machine running in the background shouldn't dominate your home. This quiet home oxygen concentrator was engineered specifically for noise-sensitive users, with a simplified cabinet design that improves sound quality by roughly 15% and holds operation to just 46.7 dBA — quiet enough for bedrooms, living rooms, and overnight use. You get continuous flow oxygen therapy from 0.5 to 5 LPM, 24 hours a day, with delivered oxygen purity of 87% to 96% at every setting.
Setup takes minutes, not an afternoon. Attach your cannula, plug the unit in, and dial the pressure-compensated flow meter to your prescribed rate. The built-in Oxygen Sensing Device continuously monitors output, and four clear indicator lights plus audible alarms alert you to low oxygen, low flow, pressure issues, or power loss — so you always know your therapy is on track. At 36 lbs with smooth-rolling casters and top and side handles, this 5 liter oxygen concentrator moves easily from room to room. Patented Turn-Down Technology reduces power consumption by 15% or more, easing the impact on your electric bill while extending the life of internal components. Assembled in the USA and covered by a 3-year warranty, it's a dependable foundation for long-term home oxygen therapy.
The 525DS-Q is especially made for those that prefer Quiet concentrators.
