In the case of CPAP
https://cleanhomeguide.com/lumin-cpap-cleaner-reviews/, in order not to suffer from still high, but now unnecessary pressure, you will have to “play” well with the setpoint but not to lower it more than necessary (carefully analyzing the results using a program like SleepyHead), or even apply for polysomnography again. If you have an APAP, then you don’t need to do anything at all. Over time, the upper limit of the pressure range will get too high, which does not lead to anything bad, the pressure will just reach, for example, not 14-15, but only 11-12, although it is still allowed up to 15.
