AirSep FreeStyle 3 Portable Oxygen Concentrator or simply known as the FreeStyle is made in the USA. At only 3.9 pounds, the FreeStyle portable oxygen concentrator provides wearable, pulse flow oxygen therapy. Carried via shoulder strap or in a backpack, the FreeStyle is a medical-grade concentrator that produces 87 to 95.5% oxygen in flow settings 1-3 (-3%/ + 5.5%). The carry case weighs 1 pound. FreeStyle provides up to 3.5 hours of battery-powered excursions on flow setting 2 or 6.5 hours on flow setting 1. The battery easily slides in or out to make being on the go easier. This lithium ion battery weighs less than 1 pound. Combined, the concentrator with the carry case and one battery weighs 5.25 pounds, less than the average woman's purse.

Unlike other portable oxygen concentrators, the FreeStyle lightweight concentrator does not require a cart to go where you go. This oxygen therapy device comes with a standard carry bag that features side pockets for an additional battery or accessory storage, a zipper cover for protection and a comfortable carry handle. The compact oxygen concentrator is FAA-approved and is just 6.1 inches wide, 8.6 inches high and less than 4 inches deep to readily slide under an airline seat and tidily fits in a vehicle.

FreeStyle runs in any flow setting off of AC (home) and DC (automobile or boat) sources, as well as lithium ion battery. When the FreeStyle portable oxygen concentrator is plugged into an AC or DC source, the battery pack conveniently charges.

FreeStyle packs exclusive UltraSense technology that minimizes the effort needed to trigger a pulse dosage. UltraSense also enables users to set the O2 device down and roam freely if a 25-foot cannula is used. To make the most of this mobility, the O2 machine has a flexible, swivel oxygen outlet.
