I'm the BMC Medical Editorial Team, which creates and reviews content on sleep-disordered breathing, respiratory therapy, and related healthcare solutions. In preparing this guide, I compared the supplied specifications for BMC Medical's G3 and E5 CPAP families, paying particular attention to therapy mode, humidification, comfort features, data pathways, and accessories. A CPAP machine in the £300–£500 range can be a practical starting point for comparison, but the supplied information does not verify a current GBP retail price. For most shoppers, the BMC Medical G3 X Auto CPAP is the strongest model to check first because its supplied specification is the most complete, including AutoCPAP modes, a 4–20 hPa range, and multiple data-transfer options.

What Is a CPAP Machine Priced Between £300 and £500?
This category refers to CPAP or AutoCPAP devices that a buyer may find within a £300–£500 retail budget. CPAP machines deliver pressurised air through a mask during sleep, while AutoCPAP machines can adjust pressure within their configured range. People typically compare this price band when looking for prescribed treatment for obstructive sleep apnea, but the final choice should be based on clinical guidance, exact configuration, local availability, and the total cost of the machine and accessories.
Because no GBP retail prices are included in the supplied information, none of the models below can honestly be labelled as confirmed £300–£500 purchases. They are potential models to check with a local supplier.

How We Evaluated These CPAP Machines
- Price clarity — We treated the £300–£500 target as unverified because no GBP retail prices were provided.
- Therapy mode — We separated fixed-pressure CPAP from AutoCPAP because the distinction affects clinical suitability.
- Comfort features — We considered humidification, ramp functions, expiratory relief, heated tubing, and noise information where supplied.
- Data and connectivity — We compared SD card, iCode, cellular, WiFi, Bluetooth, and PAP Link support only where the supplied model information identifies them.
- Buying practicality — We checked the accessory and replacement-part considerations that can change the real cost of ownership.

FAQs
Which CPAP machine is confirmed to cost between £300 and £500?
None of the supplied data includes a verified GBP retail price for the G3 X Auto CPAP, E5 C20, E5 A20, or G3 C20. These models are therefore potential options to check, not confirmed £300–£500 purchases. Prices can change by country, seller, configuration, accessories, connectivity, and availability.
What is the difference between CPAP and AutoCPAP?
A fixed-pressure CPAP delivers therapy at a prescribed pressure, while an AutoCPAP can adjust pressure within its configured range. The G3 X Auto CPAP and E5 A20 are described as supporting CPAP and AutoCPAP modes, while the E5 C20 and G3 C20 are described as fixed-pressure CPAP models. The correct mode and settings should be determined with a qualified healthcare professional.
Does the price usually include a mask and heated tubing?
The supplied information does not define a standard UK package for any of these models. Heated tubing, masks, power supplies, water chambers, carrying cases, SD cards, and connectivity modules may be included, optional, or sold separately depending on the configuration. Ask the seller for an itemised quote and confirm compatible replacement parts.
What does “CPAP machine” mean?
A CPAP machine is a device that delivers continuous positive airway pressure through a mask during sleep. It is commonly used as part of treatment for obstructive sleep apnea, with pressure and equipment selected according to an individual's clinical needs. Some devices are fixed-pressure CPAP machines, while AutoCPAP devices can adjust pressure within a prescribed range.
Where can I verify BMC Medical models and support?
You can review the BMC CPAP products category and contact BMC Medical through its official website or the supplied international email address, intl@bmc-medical.com. For after-sales questions, use the company's CPAP service support resources. Confirm product-specific regulatory status and availability for your country before purchase.
Conclusion
The BMC Medical G3 X Auto CPAP is the strongest first model to check for a feature-rich AutoCPAP comparison, while the E5 C20 and G3 C20 are more relevant to fixed-pressure therapy. The E5 A20 is another AutoCPAP option with stated response profiles. None has a verified £300–£500 price in the supplied data, so the next step is to request an itemised local quotation and confirm the exact configuration, accessories, warranty, and clinical suitability through BMC Medical's CPAP product catalogue.
