This vent is necessary for the safe operation of the mask. It reduces residual flushes CO2 in the system. The Resmed machine reports unintentional leaks, which are leaks over and above the amount of air flowing through the vent. Unintentional leaks below 24 l/min. are considered to be not objectionable from the machine's point of view. The machine can still overcome the leak and provide the proper pressure and it can still sense and discriminate apneas.

all true, that intentional and non-intentional leaks can be fairly high without changing the effectiveness of the therapy, and 20 to 24 l/min is a lot. The other thing that leaks do is disrupt sleep (for some patients) due to:
1. making noise or making the machine make more noise.
2. leaks hitting or pushing past skin, hair, or eyes.
If the leaks are as described, but do not disrupt your sleep, then it's fine!
If disruptions do occur you can actually use techniques to help minimize the disruptions. For number 2 above, for example, many use cloth pad between mask and skin. In some cases this actually increases the leak a little bit, but greatly reduces the sound of hissing, and is soothing rather than alerting. For number 1, I sometimes hang a handkerchief in front of my mask, and it slows the flow just slightly and spreads it out, decreasing the sound but the flow is still well above needed to be safe from CO2 buildup.
