Before you order — confirm these
The FreeStyle Comfort 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 FreeStyle Comfort Different
Ergonomic Curved Body — Built to Be Worn
Every other portable concentrator is essentially a rectangle. The FreeStyle Comfort is curved — designed to rest against the contour of your side rather than hang away from it. Better balance. Less swing. Less fatigue by mid-afternoon. For patients who wear their concentrator all day, the shape of the unit is not a cosmetic detail — it is felt in the shoulder and hip every hour.
UltraSense · autoSAT · autoDOSE — CAIRE's Delivery Technology
UltraSense breath detection identifies the beginning of each inhalation with high sensitivity — important for patients with shallow or slower breathing patterns. autoSAT maintains consistent oxygen saturation across changing breathing rates. autoDOSE adjusts bolus delivery in real time. Three layers of delivery intelligence from the same manufacturer behind the clinical-standard Eclipse 5.
5 lbs · 39 dBA · Up to 8 Hours · FAA-Approved
Five pounds with the standard battery. Quiet at 39 dBA — unobtrusive in a restaurant, waiting room, or place of worship. Up to 8 hours with the extended 16-cell battery. AC and DC car power included. FAA-approved for domestic commercial flight. CAIRE's 3-year limited warranty — the same manufacturer backing that covers the Eclipse 5.

Frequently Asked Questions
Standard portable concentrators are rectangular — when worn on a shoulder strap, they hang away from the body and swing with each step. The FreeStyle Comfort's curved profile is shaped to follow the contour of your side, resting closer to the body with less swing and better weight distribution. Over a full day of wear, that difference shows up as less shoulder fatigue and better balance — particularly noticeable for patients who are active or on their feet for extended periods. 866-218-0902.
Both are 5-setting pulse dose concentrators in the 4-5 pound range. The Aer X is lighter (4.25 lbs vs. 5 lbs), has a longer warranty (5 years vs. 3 years), and features the magnetic cannula port safety release. The FreeStyle Comfort has the ergonomic curved body design, CAIRE's UltraSense/autoSAT/autoDOSE delivery technology, and the brand backing of CAIRE — the same manufacturer as the clinical-standard Eclipse 5. Both are strong units at the same setting range. Come in and hold both. 866-218-0902.
The FreeStyle Comfort is a pulse dose concentrator. Whether it is appropriate for nighttime use depends on your specific prescription and breathing pattern during sleep. Your physician's guidance on nighttime use is essential before using any pulse dose unit overnight. 866-218-0902.
Yes — FAA-approved for domestic commercial flight. The concentrator checks at the gate door; batteries must be carried in the cabin per FAA regulations. Bring enough battery for 150% of total travel time including boarding, connections, and 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 FreeStyle Comfort 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.

Warm, cozy and thick high-quality throw.
Color: Cream, Size: Throw (50" X 60")
This is thick, non-shedding blanket - and for cold, winter nights… THE BEST. My granddaughters found it to be too warm, but not this grandma! I’m fit, but dang, these super-cold Alaska nights allow me to stay warm and cozy! If you have someone who runs a bit on the colder side, they will love this blanket! It washes beautifully. Great value!

10/10 Would Buy Again

This is absolutely the softest blanket I have ever purchased. It fits perfectly and looks amazing. The material is soft and comfortable. It's easy to clean and it's so warm. The faux fur is so soft and plush. Great quality. Great price.

The ultimate "cozy" blanket—thick, soft, and incredibly warm
Color: 03- Tie Dye Black, Size: Throw (50" X 60")
his Bedsure blanket is the definition of comfort. One side features a velvety smooth faux fur while the other is a thick, plush Sherpa fleece. It’s significantly heavier than a standard throw, making it perfect for cold nights. The black color is deep and rich, and I’ve been impressed that it doesn't shed at all, even after several washes. It drapes beautifully over a couch or bed and adds an instant touch of luxury to the room. It’s the perfect size (50"x60") for curling up with a book or a movie.

Buy this now!!!
Color: 15- Teal, Size: King (108" X 90")
This is probably one of my favorite purchases from Amazon. I have washed it at least 10 times so far and it still looks the same as when I bought it. It is so soft and snuggly I love it so much. The color is beautiful the furry side is soft and the bottom side has Sherpa on it which is also soft. It's not super heavy and it keeps me warm and it fits my king size bed perfectly. It is such a good value for the money and the quality of it is amazing do yourself a favor and purchase this you will get the best Sleep Quality of your life I swear. I wish I would have had this years ago I don't know what took me so long to find it I have bought several blankets and ended up throwing them away because I did not like the way they felt. This one will be a keeper.
