SleepCube AutoAdjust Plus Auto CPAP.

The SleepCube AutoAdjust Auto-CPAP has long been one of our most popular CPAP machines, and the reviews we’ve received from customers support that.

★ ★ ★ ★ ★ Rated 5 out of 5

I’m new to INTUS but a well-satisfied customer. Recently diagnosed OSA sufferer, I could not wait the nine months for the NHS to supply a CPAP machine. I found this website, and it was great to speak to someone who listened and empathised. Within two days, I had this CPAP machine, and after the first nights use, I awoke feeling more alive than I have for decades. Well done, INTUS and well done the manufacturers of sleep cube. I found the ease of use great & the benefits fantastic.

Mac – 6th March 2011

Their new SleepCube range (called IntelliPAP in the US) results from years of experience with sleep apnoea therapy products worldwide. Focusing on the demands of the present-day patient, the SleepCube AutoAdjust Plus Auto-CPAP (also referred to as APAP) is small, looks great in any bedroom and has all the features expected in a top of the range variable pressure PAP device. It is also the quietest machine we have ever supplied our patients.

Now DeVilbiss has improved the CPAP machine further by adding exhalation relief in the form of SmartFlex. A system that makes exhalation easier. This feature has turned an excellent CPAP machine into an outstanding one!

*SmartFlex – Easier, Comfortable, Natural Exhalation.

Several CPAP manufacturers have used exhalation relief technology, but DeVilbiss’ SmartFlex system takes it to a new level. You can customise both how much relief you want and how sharp you want to transition between inhalation and exhalation. You can opt for a drop in pressure of either 1cm, 2cm or 3cm, and there are five stages of transition to choose from – between sharp (rapid reductions and increases) to smooth (much slower change). That leaves you with 15 possible combinations, ensuring that whatever level of relief you require, there’s a setting perfect for you.

The SleepCube AutoAdjust Plus.

The SleepCube AutoAdjust Plus is an automatic CPAP machine and has all the benefits of variable pressure. The SleepCube advanced sensors can detect exactly how much pressure you need at any given time and foresee apnoeas developing and increase the pressure to avoid them. This feature means that you will often have a lower pressure than you would with a fixed pressure as it only rises when you need it. Many CPAP users find that this allows for drifting off quicker and gives them more comfortable therapy during the night. Because of the advanced sensors located in the AutoAdjust Plus, you can also get more detailed compliance readings from your SmartCode.

SmartCode makes feedback easy.

Almost all Auto CPAP systems have data recording capabilities – the difference with the Sleepcube is just how easy it is to access that information. There’s no need to buy a memory card or expensive software – you display your SmartCodes on the system’s display, email us your codes, and we can tell you what they mean. Want to know how effective your therapy is being? It’s as easy as emailing us a few digits, and we’ll give you the results. The best bit? There’s no charge for this service – Intus Healthcare provides it for free as part of their outstanding after-sales service.

The most convenient CPAP humidifier available.

If you wish to add humidification to your SleepCube AutoAdjust Plus, you can take advantage of arguably the most intelligently designed humidifier available – the SleepCube Humidifier. This option is available separately, and the Sleepcube Auto Plus simply sits on top of the humidifier, which means the same small footprint on your bedside table. 

No need to find any extra space to accommodate it! 

The design also means the air inlet then sits higher, helping prevent it from sucking in dust that can gather on surfaces. If you find yourself waking up with a dry mouth or finding the air uncomfortably cold, a humidifier solves this by adding warm moisture to the air supply. The SleepCube Humidifier’s water chamber is dishwasher safe, making it easy to clean.

Are you using CPAP on your travels? Look no further.

The SleepCube’s compact size makes it an ideal travel option. It can be powered using a 12V cable (available separately), allowing you to use it in a car, on a boat or in a caravan. Its auto-adjusting power supply means it can accept any mains voltage between 100-240V, meaning you can use it in almost any country across the globe. It comes supplied with a carry bag making transportation easy and comfortable.


A 3-year warranty that gives peace of mind.

DeVilbiss offers a three-year warranty with their SleepCubes; such is their confidence in building quality and longevity. The industry-leading warranty means you buy with peace of mind.
