The newly designed AirSep FreeStyle 5 provides oxygen settings from 1 to 5 and adds new important features that include a simple, one-touch operation, longer battery life, and a new color scheme. It also features a new power supply connection that ensures the highest durability of both the power supply and FreeStyle 5 portable unit.

Just like the FreeStyle, the FreeStyle 5 features a great manufacturer’s warranty which covers 3 years on the base unit and 1 year on the battery and power supplies. This gives you peace of mind and assurance that your investment is protected.

The average sound volume is a soft 48 decibels, quieter than a normal conversation. This is another way the FreeStyle 5 provides you with freedom since you’re free to enjoy life even in quiet areas or social settings.

This unit also includes a generous amount of accessories, such as a carrying case with a shoulder harness. There’s even an included accessory bag, AC and DC power supplies, power cord, and, of course, a battery.

Naturally, the unit is fully FAA approved for in-flight use. The accompanying power supplies and average battery life of 2.5 hours allow you to travel by airline with no hassles.

In fact, when it comes to batteries, the power supply is designed to be easily accessible from the front of the device and can be directly charged with AC or DC power. The power supply uses a multi-directional installation with rugged, strong prongs and has no release button, preventing you from having to struggle just to change it out.
