Replacing CPAP accessories on a regular basis is important for getting the optimum benefits from your sleep therapy. Filters need replacing every 6 months, or twice a month if you’re using the disposable kind. They become clogged over time, and new ones are critical to keep your machine running well. Pillows and cushions should be changed twice a month. Because they rest against your skin, the oils and dirt from your face cause wear and tear on these supplies which is why they need to be replaced more often than other supplies. Headgear, chinstraps, and non-disposable heated humidification chambers should be changed twice a year. CPAP supplies are designed for comfort and flexibility, not endurance. Routine replacement can help prevent infections and help keep your supplies in good working order. If you don’t see what you need, email us, we are happy to help.
