In essence, there are 3 different flavors of CPAP masks illustrated below. Due to the huge variation in face shapes and sizes, there is no "best" CPAP mask and often, a patient may need to try different styles, size, and strap placements before finding one that works and fits the best.
For each mask style, there are many variations with respect to strap placement, mask size, and tube placement.
With respect to tube placement, it typically comes from either the side or is looped up over the forehead. The pics below demonstrate a few basic styles for each mask type. The first column shows full face masks, the second column shows nasal masks, and third column shows nasal pillow masks.
