Before you order — confirm these
The Aer X is a pulse dose concentrator only — it does not deliver continuous flow. Not appropriate for prescriptions specifying a continuous flow rate (LPM). Pulse dose during sleep requires physician guidance. Battery life specs are manufacturer best-case figures — in SW Florida summer heat, plan for 70-75% of published runtime. 866-218-0902
What Makes the Aer X Worth a Closer Look
Magnetic Cannula Port — A Daily Safety Feature
Your tubing catches on something — a cabinet handle, a doorknob, a chair leg. With a standard concentrator, that tug goes straight to your nose or pulls the unit off your shoulder. With the Aer X, the cannula simply releases from the device. No yank, no stumble, no interrupted flow. Reconnects in one second. For patients who move frequently through the home, this is not a novelty — it is a daily safety improvement.
4.25 lbs · Lightest 5-Setting Unit Available · Made in the USA
The lightest concentrator on the market with five pulse settings — built in the United States. Auto X Technology automatically adjusts oxygen output as your breathing rate changes, working harder when you are active and settling back at rest. 5.5 hours of battery life. 40 dBA. The 5-year manufacturer warranty leads the category.
5-Year Warranty — Strongest in Its Class
Most portable oxygen concentrators carry a 3-year warranty. The Aer X carries 5 years — the strongest manufacturer warranty available in the pulse dose category. For a device you depend on every day, that extra coverage is not a minor detail. It is two additional years of protection on the most important piece of equipment you own.

Frequently Asked Questions
The cannula connects to the Aer X via a magnetic port rather than a friction fit. When the tubing catches on something and tension builds, the magnet releases cleanly before the force reaches your nose or pulls the unit off your shoulder. You reconnect by bringing the cannula back to the port — it clicks back into place in about a second. Flow interruption is minimal. For patients who move through their home frequently, it is a feature that makes a noticeable difference within the first week of use. 866-218-0902.
Auto X Technology monitors your breathing rate in real time and adjusts the oxygen output of the Aer X automatically — delivering more when you are active and breathing faster, less when you are at rest and breathing slower. You do not need to manually adjust settings as your activity level changes throughout the day. It is similar in concept to Inogen's Intelligent Delivery Technology. 866-218-0902.
Both cover settings 1-5 (the G5 goes to 6). The Aer X is lighter (4.25 lbs vs. 4.7 lbs), carries a longer warranty (5 years vs. 3 years), and adds the magnetic cannula port. The G5 has a longer clinical track record and the broader service infrastructure of the Inogen brand. If you want the lightest 5-setting unit with the best warranty and a safety-first design, the Aer X is the answer. If you want the most proven brand name and an 8-year service life, the G5 is worth considering. 866-218-0902.
Yes — FAA-approved for domestic commercial flight. The concentrator checks at the gate door; batteries must be carried in the cabin. Bring enough battery for 150% of total travel time including boarding, connections, and potential delays. Call the airline at least 48 hours before your flight. 866-218-0902.
Yes. Our 10-Day No-Risk Trial lets you take the Aer X home and use it in your actual life for 10 days. If it is not the right fit, bring it back and we will exchange it. No restocking fee, no fine print. Walk-ins welcome at all five SW Florida locations. 866-218-0902.

Nice leggings......but
Special Size: 19" Capri without Pockets, Size: Small, Color: Taupe
So, I bought two pairs on sale....one in navy and the other in taupe. Both pairs have a streak mark on the same side, same exact area. I'm on the fence about returning them but I did get them on sale and if the mark doesn't come out in the wash, I can't really wear the in public unless I wear something long to cover the upper thigh area. They fit great and are very comfortable but then there is that unsightly mark. For reference, I am just under 5'0, 105 lbs and bought size small. I will have a think about it the next few days about returning them...or not.

Runs large
Size: 5-6 Years, Color: Purple
This tennis dress does run a bit large, so I’d keep that in mind when ordering. I was also disappointed to realize the shorts underneath are not actually attached, since I expected more of a built-in skort style. The dress itself is cute though and the color is very pretty.

cute tennis dress!
Size: 7-8 Years, Color: Purple, Size: 7-8 Years, Color: Purple
This is such a cute outfit. It has been an instant hit with a 7-year-old who loves to match her outfits. This tennis dress comes with matching shorts underneath. It is a sporty, shorter dress, so the shorts are needed. It fits very comfortably and looks and feels like active wear. The fabric and the cut are good quality. It also fits true to size for someone slightly over 4 feet tall. We are not using this for playing actual tennis, but the style and design definitely match the classic tennis outfit look. Still, this can just as easily be worn to school or on play dates, or simply playing around the house.

Great Color and Stylish Activewear
Size: 5-6 Years, Color: Purple, Size: 5-6 Years, Color: Purple
This girls’ tennis and golf dress stands out with a really great color and a stylish, sporty look. The fabric feels lightweight and breathable, which should be great for active movement and staying comfortable. I like that it includes built-in shorts with pockets, adding both coverage and convenience. The racerback design and fitted cut give it a modern, athletic style that’s perfect for sports or even casual wear. It seems well thought out for both performance and everyday use. Overall, a cute and functional outfit that’s both practical and stylish.
