Product Description

The AirSep Freestyle 5 is a wearable portable concentrator that offers 5 different pulse setting, and ensures that you can have the total access you need in a compact lightweight portable concentrator. This is a very long-lasting, sturdy and dependable portable oxygen concentrator, at only 6.2 lbs. It's also very low-maintenance. Besides periodically cleaning or replacing the intake filter to make sure you are always getting the cleanest and purest oxygen, you won't need to do any major maintenance or have it repaired for years to come. A wipe down with a lint-free cloth is something you should do every now and then to keep the outside clean, and keeping it inside the case will also keep it free of dust and anything else that can make the outside of the concentrator dirty.

If you enjoy getting your regular exercise, this portable oxygen concentrator can go with you to the gym, and stay out of your way as you go about your routine. Your Freestyle 5 comes with the standard shoulder strap used to carry it around, but you can opt for the backpack for the most comfort and convenience, especially while you are working out.

This portable oxygen concentrator is only 4.4 inches wide, by 10.7 inches high and 1.2 inches deep, so you won't need to worry about knocking into things while you are wearing it. It will stay safely tucked against your side, or snug up against your back with the fully adjustable straps. The backpack's straps are soft and the backpack is padded for maximum comfort.

Even if you go somewhere quiet, like the library or a movie theater, you won't need to worry about your Freestyle 5 being too noisy. It's only anywhere between 38 to 44 decibels, depending on the setting it's on. This is equivalent to a whisper, and not enough to disturb anyone. It's great for taking on overnight flights, since it is FAA approved for taking on an airplane, and because it's so quiet.

You can enjoy up to 7 hours of total freedom, if you incorporate the AirSep Airbelt as a supplemental battery to the already long internal battery life of the Freestyle 5. Alone, the internal battery will last up to 2 hours on the setting of 2.

The AirSep Freestyle 5 Starter Package includes the Freestyle 5 unit, internal battery, AC & DC power supply, shoulder strap, cannula and user manual. It features a 3 Year Warranty on the unit and 1 Year Warranty on batteries and accessories.

We also provide a AirSep Freestyle 5 Battery Package that comes with the Freestyle 5 and the AirBelt.

"Convenient and light weight. Easy to use." AirSep Freestyle 5 Portable Concentrator

Review by on May 28, 2015

I am very happy with my Airsep Free Style portable concentrator. I had it for 4 years and then had to have it repaired which I think was only a new internal battery. While it was being fixed I was given another kind which was nice as well, but much larger and would be great for someone who was stronger as it was on a cart. I now have my airsep back and am wondering if it can remain plugged in continually or should it be disconnected from the power supply after it shows a charged battery?

"Great little machine" AirSep Freestyle 5 Portable Concentrator

Review by on July 11, 2013

I guess I'm lucky – I'm able to get a good 7 hours of battery life before I recharge. I use the airbelt and I only need the lowest setting this things has.

"Small wonder" AirSep Freestyle 5 Portable Concentrator

Review by on July 2, 2013

I'm impressed with how this thing holds up with how little it is. I also use oxygen constantly and I live in a pretty hot climate. With little maintenance and care, this thing is pretty tough.

"Not the best I've seen" AirSep Freestyle 5 Portable Concentrator

Review by on July 1, 2013

It's very small, which naturally means it doesn't have the features the others have that you may need. Great if you need low flow and that's all, but you have to consider other features. Check out others before going with the smallest!

"Battery is a pain" AirSep Freestyle 5 Portable Concentrator

Review by on June 27, 2013

The only thing I can see wrong is the battery takes over 3 hours to charge again. This seems long, as well as the shortness of the battery life on the highest setting, which is what I need. Seems I would do better with a bigger model.

"Freedom" AirSep Freestyle 5 Portable Concentrator

Review by on June 27, 2013

The name Freestyle is right. I feel so much lighter and free now that I got rid of my tanks. The style part is even true to how small and stylish it looks.

"Ok battery life" AirSep Freestyle 5 Portable Concentrator

Review by on June 26, 2013

I use it on a setting of 2 and I also know that the smaller the concentrator usually means a smaller battery. You take the good with the not-so-good. I have great little concentrator, so the little battery is fine with me!

"Made in the USA" AirSep Freestyle 5 Portable Concentrator

Review by on June 26, 2013

I was glad to find out that this particular machine was made in the US, which was another selling point for me. The small size is really nice and convenient and I take it with me on my truck runs. Great little concentrator.
