Benefits of the Freestyle for Oxygen Therapy Users

The Caire Freestyle POC offers significant advantages over traditional oxygen therapy methods. Tanks and cylinders restrict mobility, and compact portable oxygen can't match the Freestyle's performance.

Here are some of the top benefits of the Caire Freestyle portable oxygen concentrator:

Ultimate Portability

The Freestyle's compact size and featherlight weight allow you to carry it discretely in the included shoulder bag. The unit can be slipped under airline seats with ease to enable travel. Its portability grants you the flexibility to go anywhere and do anything while on oxygen therapy.

Uninterrupted Oxygen Supply

This POC never runs out of oxygen like small compressed oxygen canisters do. The Freestyle produces an uninterrupted supply of oxygen from the ambient air around you. As long as it has power via battery or AC outlet, you have access to oxygen.

Higher Oxygen Concentrations

Typical portable concentrators produce 90-95% oxygen but the Freestyle delivers 96+% oxygen purity levels at all settings. This helps maximize the benefits of supplemental oxygen therapy.

Intuitive Controls

Large touch buttons and a user-friendly interface make the Freestyle incredibly easy to operate. There are no complicated settings or maintenance required.

Whisper Quiet

You can hold conversations, watch TV, and sleep soundly while using the Freestyle. It produces only 39 dB on setting 2.

The Caire Freestyle POC provides the oxygen you need with the freedom you want. Contact your medical supply provider today to see if the Freestyle is right for you.

Frequently Asked Questions

We guarantee our price to be the lowest of any Inogen One Authorized Dealer.  Be careful; there are only two of us in the USA! The others are buying somewhere other than Inogen One, the manufacturer.  In some cases, these are used machines that are represented as "New".  We always strive to offer good value and have special deals on our oxygen concentrators. But if you’re struggling to fit the oxygen concentrator, you need into your budget, or have found a competitive price elsewhere, speak to us. We always put our customers’ needs before profits. 
Medicare will not purchase any Inogen One System, as Medicare classifies these as “Luxury Items.” Most insurance companies take the same stance as Medicare. However, a few insurance companies will reimburse all or part of your Inogen Oxygen system after purchasing and submitting the required claim forms. Inogen One Systems are the best on the market; owning the very best in portable oxygen is worth the investment.
Here at Main Clinic Supply, we believe that everyone should have the chance to live their lives to the fullest! While many insurance companies and programs classify our state-of-the-art portable oxygen concentrators as "luxury items," we know they are anything but. As an oxygen user, you deserve access to oxygen equipment that will allow you to stay active and healthy.  Because of this, we have partnered with PayPal Credit and CareCredit to help make sure that every oxygen user has the chance to own the very best in portable oxygen and enjoy the freedom and mobility that it brings! Apply or check our options here.
You may fax your prescription for oxygen to us at 1-800-819-7179 or email rx@mainclinicsupply.com. We are also happy to the obtain the prescription for you after you place your order here online.
Free trials are something to be wary of. The majority of medical oxygen dealers share an interpretation of a “New Oxygen Concentrator Machine”, as a machine that has less than 100 hours of previous use. They don’t actually offer you a free trial, just a used machine you are made to think is new. At Main Clinic Supply, new means new, or never used before!
