A: We suggest replacing all your cpap supplies every 6 months. Many times your physician will recommend this as well. The headgear on your mask will stretch over time and the mask cushion or pillows will discolor, get an odor, become soft and pliable and leak more from the oil in your skin. Your mask will not seal well when this happens.
The filters on the air intake clean the air you breathe and should be kept clean. Extremely dirty filters can cause your pressure to be decreased. Monitor your tubing especially near the thick rubber ends for stretching. This is a common place for them to tear. Water chambers will often get hard water build up, especially if distilled water is not used regularly. It is a good idea to keep an old water chamber, tubing and mask on hand for back up as well.
