APEX Medical XT Auto CPAP Machine with Heated Humidifier

The APEX XT Auto is as sturdy as it gets, and when paired with a humidifier, it's a winning combination. Despite its small stature compared to other machines on the market, the XT Auto does not skimp on performance, packs a technological punch, and can withstand the daily/nightly rigors of sleep therapy on its own. The XT Auto with humidifier offers advanced technology, such as a Pressure Variation Algorithm, an Auto Adjusting Algorithm, and a user-friendly LCD display, all wrapped in a portable package.

Pressure Variation Algorithm
PVA – Pressure Variation Algorithm – is designed to automatically reduce pressure during exhalation and then return to the set pressure during inhalation. Reducing pressure during exhalation significantly reduces discomfort commonly associated with CPAP therapy and leads to increased effectiveness and comfort. The APEX XT Auto includes 3 different settings so you can personally adjust the exact amount of pressure relief suited for your needs.

Auto Adjusting Algorithm
The Auto Adjusting Algorithm from APEX XT automatically adapts to sleep events and keeps the air pressure at the most comfortable and lowest levels during your CPAP therapy. Your therapy will remain effective, and the performance of your CPAP device will be uncompromised.

Ultra Compact Design
The APEX XT is designed to deliver quality CPAP therapy, and it does just that. If you travel frequently or need to save space, you’ll find the APEX XT Auto perfect as you can dislodge it from the humidifier, truly experiencing what a compact unit is all about.

User-Friendly Interface
Usability is a core focus in the APEX XT. This APEX medical CPAP machine features a large LCD display with an easy-to-navigate menu and simple buttons to ensure a quick and hassle-free experience. You can get to the settings you need and find the information you want quickly. All your therapy information is saved onto your SD Card that you can easily link to your PC to view your sleep therapy data. This enables you and your physician to take action with your sleep data, improving compliance and sleep apnea therapy effectiveness.

Internal Power Supply
The APEX XT gets rid of an external power supply to increase portability. This is a boon for frequent travelers who need fewer parts and more mobility. The built-in power supply means fewer things to carry; however, the machine must be plugged into the wall in order to be powered.

Heated Humidifier

In consistency with the theme of portability, the humidifier for the APEX XT remains compact and simple. Humidifiers significantly reduce the common irritations associated with traditional CPAP therapy. People who undergo CPAP therapy often suffer from irritation of the throat and nasal passages which can disrupt their sleep. A humidifier actively works to ease the irritation caused by CPAP therapy for a discomfort-free night. The humidifier for the Auto XT is simple and compact, making it an easy companion to carry.

Reviewers Tip:
The water chamber is dishwasher safe, but it is highly recommended to hand wash the water chamber in warm water. There is a high probability that the silicone seal may get damaged from extensive cleaning in the dishwasher, and repeated washings could reduce the life of the seal dramatically.

Please note: 2-year warranty is voided by water damage/misuse of the machine.

Introducing the APEX XT Series CPAP Machines


Is the filter disposable or reusable?
The filter included with the APEX XT is, in fact, reusable. With regular care and maintenance, the filter should last up to 6 months. It is recommended that you clean the filter every two weeks at the minimum, and more frequently if you live in a dusty environment.

I travel internationally frequently, do I need a converter?
The APEX XT CPAP machine is able to handle international power grids that range from 100 volts to 240 volts without needing any adjustment. However, you may need a plug adapter to plug into the power outlets depending on the country you're in.

Does the machine come with a heated tube?
No, all travel CPAPs come with a standard tube. However, the APEX XT is the only travel-friendly machine that comes with a detachable humidifier.

This is my first purchased from Respshop.com and im very pleased with the machine, I have been sleeping so good and so as my partner. The XT Auto has 3 different settings I can choose from to adjust the pressure relief that suits my needs. User friendly machine, all my therapy information is saved on the SC card and I can easily link it to my PC to view all my sleep therapy data. The heated humidifier is an a plus for me it helps with my dry throat or nasal congestion. Water chamber is easy to care for, dish washer safe but I prefer hand washing it with warm water.

I tried using both in cpap mode and auto mode, found out that I prefer the auto mode, but it is good
to know that the cpap mode is not for me. Else, I have to buy two machines before I figure out which meets my need.

This machine helps me sleep well at night, and my health improves dramatically! Should have used it a long time ago, when my doctor told me I needed one, but didn't have the means to get one then. The price is perfect for my budget. At first I didn't think I need the humidifier, but bought it anyway because I read on your website that it helps prevents dryness. Good advice, thanks guys.

Only wish the humidifier was smaller. Machine works great though. Wish they could make a smaller humidifier to go with the small machine. Still good for travel and smaller than my respironics

Can you connect the hose directly to the machine without the humidifier, or is there an adapter available to allow that? I like using the humidifier at home, but when travelling, would like the option to not use it as well. (Asked on 07/15/2022)
Yes, you can plug the hose in directly to the machine, where the humidifier connects to the machine.
