"The Liberty Headgear is available in 2 sizes. Standard comes with the masks. There is a smaller size available. The difference is the top headgear straps are 1 1/2 inches shorter. The label on the back of the headgear indicates SMALL; there are no other differences. The "halo" is the exact same size. The bottom straps are the same length."

flimsy construction
Hannah F, NH – March 26, 2011
"It was great for the first week - despite blisters in my nostrils....But then, after daily cleaning - the cushion never fit properly back into the frame. I do like a clean mask daily and am careful to use proper water temperature and cleansing agents....This mask was rendered useless after 2 weeks....The mask eventually leaked all over the place. For the price - I expect something more durable."

Do you have a guide to help me choose the right mask?
Yes, we created a Help Me Choose guide to help you select the right mask or machine according to your preferences. The guide asks you a series of questions regarding your preferences and your facial features. Based on your answers we provide you with a comparison chart of the masks that meet your criteria.

How often should I replace my mask?
Medicare allows for mask cushion replacement every three (3) months, and a complete mask system replacement every six (6) months. CPAP manufacturers and vendors suggest these replacement schedules as well.
In our experience, most mask cushions begin to deteriorate after about six months of use. The cushion eventually becomes too soft to hold a seal. The headgear straps lose elasticity and must be tightened more and more to get the same quality seal.
We strongly suggest replacing cushions and pillows as soon as they start to soften. Air leaks may reduce the effectiveness of CPAP therapy and headgear that is too tight may cause facial sores at pressure points. In most cases, replacement headgear is available if it is stretched out or the Velcro worn out.
To see what parts of your mask are replaceable refer to our Replacement Part Finder. Just search for your mask to see all of the replaceable parts.
How do I care for my mask?
Masks should be washed daily with warm water using a very gentle soap or baby shampoo, and left to air dry. Never use antibacterial soap as it will break down the silicone of the mask cushion. Avoid soaps that include lotion which can coat the mask and cause it to lose its seal. A safe cleaner is the Control III Disinfectant CPAP Cleaning Solution. Remember, going to bed with a clean face will improve your seal and protect the lifespan of your mask.
The best time to clean your mask is in the morning after use. This removes the oils left behind from your skin which can reduce the lifespan of your mask. We recommend using mask wipes to make daily morning cleaning easy. The mask wipes are made from materials that will not break down your mask.

Why might I need a full face mask?
If your mouth drops open during sleep, a full face may be selected to allow for the CPAP airflow to be delivered through both the nose and mouth.
Some CPAP users move to using a full face mask after finding that using a nasal mask along with a chinstrap does not meet their sleep therapy needs. Some CPAP users use a full face mask when suffering from seasonal allergies.
