Why does my CPap mask make rattling sound when inhaling?

This is an excerpt from the internet on that issue:

Problem in Mask Fitting

A CPAP mask that does not fit properly will allow air to leak out at higher pressures. Make sure the seal around your mask is secure. Use mask wipes or warm, soapy water daily to remove oil and dirt residue on your CPAP cushion. Reference your mask's user guide to determine if your mask size is too big or small.

Full face masks: cover from bridge of nose to just below bottom lip

Nasal masks: cover from just under nose bridge to just above upper lip
Nasal pillow masks: should fit comfortably inside the nostrils with minimal effort.
You may need a larger or smaller mask size if it does not fit properly. If your cushion is damaged, be sure to replace it immediately. Any one of these issues could be contributing to a whistling CPAP setup.

Problem in Hose Connection

CPAP tubing is very important; it's what allows the air being generated by the CPAP machine to travel to the user airway, keeping it open. If the tube is improperly connected, it could be allowing air to leak out, resulting in whistling noises. Ensure the hose is securely attached to both the CPAP machine and the mask.

Hose Needs to Be Replaced

A worn-out hose may develop tears or cracks allowing air out. If you find damage to your hose, replace it. This should be one of the first steps taken, as it can generally be the least expensive

It is probably fitted wrong.
