Frequently Asked Questions

Do you offer custom mask fitting?
Yes. Mask fit is one of the most important factors leading to successful therapy and good sleeping. Our sleep therapy specialists have developed techniques to maximize therapy and comfort by custom fitting your mask to the unique size and contours of your face.

Can I exchange my mask if I don’t like it?
Yes. As part of our Mask Return and Resupply Program, if for any reason you are not happy with your current mask and wish to try another, we will accommodate your needs at no cost. While health insurance will usually pay for replacement masks every 3-6 months depending on your insurance plan, we do not make our customers wait this long for a replacement mask if the original fitting did not work.

What if I received my mask or machine from a different supplier?
It’s no problem. We can do anything from refilling your current prescription to refitting and retraining you on a replacement mask or machine - but with the added guarantee of our Return and Resupply program.

Will I have to be on the CPAP for the rest of my life?
Since there is not a cure for Obstructive Sleep Apnea, a CPAP can be used each night during sleep to effectively treat this condition.

How often do I need to replace my mask?
Your mask is designed to last for a minimum of three (3) months, and a maximum of six (6) months with regular cleaning. We will show you how to properly clean your mask and look for telltale signs of issues with your equipment and supplies. You can also extend the life of your mask by washing your face each night to remove oil and dirt.

What does it mean if I wake up gasping for air?
This is a classic sign that you are still experiencing an obstruction. If this occurs more than once, notify your physician; you may need the pressure slightly increased on your CPAP.

What does it mean if I still wake up tired?
This is another classic sign that you are experiencing either obstructions or apnea. You should notify your physician; you may need the pressure slightly increased on your CPAP.

Why do I wake up with dry, irritated eyes?
Typically, this occurs because of a leak between the mask and your face near the eyes; air is blowing in your eyes all night and dries them out. Try re-adjusting the mask while you are lying down. If the mask is more than six months old, consider having it replaced.

Why do I wake up with water in my mask?
If this occurs, please try the following tips:

  • First, make sure you are not filling the humidifier chamber above the fill line.
  • Condensation can occur when the temperature in your bedroom is cooler than the temperature in your tubing. Try decreasing your humidifier setting.
  • If you require the increased level of humidity, then it may be beneficial to insulate your tubing. Contact us for further information.
