Maintaining your CPAP supplies for better sleep

The benefits of sleep apnea therapy can be extremely rewarding. With nightly therapy, you can reclaim your life and rediscover the energy and interest to return to your hobbies. To get the most out of your therapy, you must take care of your equipment, which means replacing your CPAP supplies regularly. CPAP users who regularly replace their supplies report that they sleep more hours each night, and they successfully use their therapy more nights each week.1 Your CPAP system is made up of multiple parts. Just like a car, the system works best with proper maintenance, which involves the replacement of certain parts as needed.

The different parts of your CPAP supplies

CPAP mask and tubing

Your mask and tubing are what connect your CPAP device to your face and airway. They should be comfortable, flexible, clean and free of discoloration. Learn more about signs that your mask and tubing need replacement.

CPAP device and filters

Your CPAP device is a small machine that delivers air pressure to splint your airway open. To protect you from dust and allergens, your CPAP includes an air filter that requires regular replacement to work best. Learn more about the life span of a CPAP device and when to replace your air filter.

CPAP humidifier and water chamber

Your CPAP device may include an attachable humidifier that warms and adds moisture to the air delivered from the machine. Humidifiers make CPAP therapy more comfortable. They include a water chamber which should be clean, clear and free of discoloration. Learn more about maintaining your humidifier and water chamber.

Just like a personal care item, for example, a toothbrush, CPAP equipment requires proper maintenance. It comes in contact with the face, and it can collect moisture and bacteria, which may lead to breakdown over time with regular use. In particular, replacing mask cushions and items that contact the face can impact your overall comfort and experience. Just as you replace your toothbrush regularly, CPAP users should replace the components of their CPAP system according to recommended guidelines.
