SISTEMMA is a user-oriented e-commerce market space for CPAP products and accessories. Although we specialize in new and used CPAP equipment, our focus is on the health and well-being of our customers. So we are interested in your experiences as CPAP users, and how we can best serve the needs of those with sleep apnea conditions.

SISTEMMA is owned and operated by a CPAP patient, and therefore shares the need for up-to-date information on breathing therapy technologies and their applications.

SISTEMMA offers a range of CPAP devices to meet the growing demand for convenient bedside therapies that no longer obstruct breathing with unnecessary airflow.

CPAP technologies have come a long way since initially developed, and comfort levels have greatly increased. Whether you are new to CPAP, or are a returning customer with years of experience with ventilation therapies, SISTEMMA is an ideal destination offering nearly every model available, and with a sizable discount from standard clinic prices.

Sleep apnea is a life threatening condition. While for most individuals with sleep apnea, the primary concern is quality of sleep, there is also the chance for serious problems if the condition persists. Here at SISTEMMA we can direct you to the most beneficial option for your specific symptoms and sleeping habits, and if cost is concern there are sales options up to 50% off the current market value.

We are here to help you find what you need, so please feel free to offer feedback on our product lists and what you like to know more about.


SISTEMMA is offering a full 2-year in-house warranty for all new CPAP machines we sold (unless otherwise stated on the listing). In case your machine is malfunctions please contact us directly.

We also are not licensed to set up CPAP machines. We can, however, review products and offer suggestions about their use and characteristics.
