Why Buy Refurbished S9 Instead of New?
The ResMed S9 AutoSet delivers the same AutoSet therapy algorithm as newer models at a fraction of the cost. For patients who need a reliable, clinically-validated CPAP without paying for connectivity features they won't use, the S9 remains an outstanding choice — especially RRT-certified and inspected.
