It's small, lightweight and easily one of the most comfortable portable oxygen concentrators to offer a pulse flow of 1-4, it provides you with exceptional battery life with the option of 3 different battery size options (most units have no more than 2) and it's easily one of the most reliable portable oxygen concentrators on the market.
By combining a compact design while keeping it lightweight, you can get back to living your life without being weighed down.
Oxygen Output
The single most important factor to consider when purchasing or renting a portable oxygen concentrator is the oxygen output of the machine and if it will meet your medical grade oxygen requirements as prescribed by your doctor.

Size and Weight
If you are wanting a pulse dose of up to 4 in a lightweight and compact unit, the ARYA Mini is one of the smallest and lightest units on the market today.
At it's lightest your ARYA Mini weighs in at a mere 3.3 pounds and stands just 6.2" D x 3.4" W x 6.7" H with the single battery installed.
Please keep in mind, if you decide to use the double or triple battery, the ARYA Mini's weight will slightly increase but you'll be able to enjoy longer portable operation compared to the single battery.
When you're battling a respiratory disease like COPD or cystic fibrosis, the size and weight of your oxygen concentrator can make a tremendous difference for your daily lifestyle.
Using larger, heavier concentrators can be difficult to transport and may require a lot of your energy or even a cart, but that's simply not the case with the ARYA Airtivo Max portable oxygen concentrator.

There were a couple other concentrators that came close to being named the best pulse flow portable oxygen concentrator, but the ARYA Mini supplemental oxygen concentrator is the total package. Here are the two other concentrators that the ARYA Mini beat out for the title of "Best Pulse Flow Portable Oxygen Concentrator"
2nd Place- ARYA Airtivo Max
3rd Place- ARYA Q
Best Overall Continuous Flow Portable Oxygen Concentrator: Oxlife Liberty 2
When it comes to continuous flow portable oxygen concentrators, they all have similar features and the unit specs are comparable across the board. So picking the top unit in this category wasn't easy, but the Oxlife Liberty 2 barely edged out its competitors.
What Makes the Oxlife Liberty 2 the Best Continuous Flow Portable oxygen Concentrator?
The Oxlife Liberty 2 has quietly risen to the top of our list as the best continuous flow portable oxygen concentrator this year. Mostly because of the Oxlife Liberty 2 has a high oxygen output in both pulse and continuous flow settings, it comes with a carrying case and padded shoulder strap (no need for a cart), all why weighing just 7.5 pounds!
Oxygen Output
The Oxlife Liberty 2 oxygen concentrator offers both continuous flow oxygen delivery and pulse flow oxygen delivery meaning it can accommodate the majority of oxygen patients 24/7/365.
It offers continuous flow settings 0.5-2.0 LPM and pulse flow settings 1-10 making it perfect for everyday use, traveling, and anything in between!
As stated above, you can use this machine 24/7/365 as long as you can plug it into the AC or DC power supply or as long as you have charged batteries.
When the Oxlife Liberty 2 is plugged into the AC or DC power supply it can provide you with an endless supply of oxygen, making it the perfect unit to use for your nighttime oxygen.
Size and Weight
When it comes to continuous flow units, the majority of them weigh over 15 pounds. This is because a larger compressor and motor are needed to produce a continuous flow of oxygen.
With that being said, the Oxlife Liberty 2 is one of the smallest and lightest continuous flow portable oxygen concentrators on the market!
Standing just 9.9" W x 3.8" D x 9.9" H, the Oxlife Liberty 2 can fit underneath the seat on an airplane to make traveling as easy as possible.

The Oxlife Liberty 2 can be operated on the go with a rechargeable battery, and with the battery installed, the Oxlife liberty 2 weighs in at only 7.5 pounds.
Battery Life
With continuous flow portables you have two different battery ratings; one for pulse flow settings and one for continuous flow settings. When using the machine on continuous flow, the compressor and motor are constantly running, which uses more battery life.
The GCE Zen-O is one of the top continuous flow portables in terms of battery life. Here is a chart with the expected battery life of the GCE Zen-O:
| Pulse Flow Rate | Pulse Flow Battery Life | Continuous Flow | Continuous Flow Battery Life |
