I use a CPAP machine and my mask split so I looked online for a spare part because it's easier than going to the hospital.
I found a whole sleep apnea machine for her which is a nice white colour with a pretty pink light and flowers, as opposed to the black one. Of course the "male" product is the default or regular machine.
You can also buy a mask for her which is absolutely identical in design but it says it is has elegant pink straps to support your chosen hairstyle. It does say it is slightly smaller than the male mask but since you can choose your size anyway this is irrelevant.
At least the price is the same and there is no pink tax.
