A typical CPAP machine is relatively compact and portable, often comparable in size to a small shoebox or a large alarm clock. Their size varies depending on the model and features included, such as a built-in humidifier.
Understanding CPAP Machine Size
When considering the size of a CPAP machine, two key factors are typically measured: its physical dimensions (length, width, height) and its weight. These factors influence how much space the machine occupies and how easy it is to travel with.
Based on the comparison of some of the top machines in August 2024, here are examples of CPAP machine sizes:
| Machine | Weight (pounds) | Dimensions in inches (L x W x H) |
|---|---|---|
| ResMed AirSense 11 Auto | 2.5 | 10.21 x 3.72 x 5.45 |
| Luna G3 BiLevel 25A | 3.74 | 10.4 x 5.7 x 4.5 |
As you can see from these examples provided by NCOA's adviser sleep experts, machines like the ResMed AirSense 11 Auto are quite light at 2.5 pounds and have a slim profile, while others such as the Luna G3 BiLevel 25A are slightly heavier and bulkier.
Practical Size Considerations
- Portability: Smaller, lighter machines are generally easier to pack for travel.
- Bedside Table Space: The dimensions determine how much room the machine will take up on your nightstand.
- Integrated Features: Machines with built-in humidifiers or other features may be slightly larger or heavier than basic models.
While sizes can vary, modern CPAP devices are designed to be discreet and fit comfortably in most bedrooms.
