Frequently Asked Questions About the Freest-5D Portable Oxygen Concentrator

What is the difference between 16-cell and 8-cell oxygen concentrators?
The Freest-5D’s 16-cell molecular sieve system provides superior oxygen output stability, longer operational lifespan, and more consistent 93% oxygen purity compared to standard 8-cell models. The 16-cell configuration means doubled filtration capacity, resulting in better performance during extended use and higher flow rates.
Can I use the Freest-5D portable oxygen concentrator while traveling?
Yes, the Freest-5D is designed for portability and travel convenience. Its compact size and lightweight design make it suitable for car travel, hotel stays, and moving between rooms. However, always consult your healthcare provider before traveling with oxygen therapy equipment and check airline regulations if flying.
How often does the Freest-5D require maintenance?
Regular maintenance includes cleaning the external air filter weekly and replacing it every 6 months. The internal molecular sieve beds typically last 3-5 years with proper use. Professional servicing is recommended annually to ensure optimal performance and oxygen purity levels.
Is the Freest-5D suitable for 24/7 continuous use?
Yes, the Freest-5D is engineered for continuous operation and can run 24 hours a day. The robust 16-cell design provides excellent heat dissipation and component durability, making it reliable for patients requiring round-the-clock oxygen therapy.
Does the Freest-5D work during power outages?
Oxygen flow rates are prescribed by your physician based on your specific medical condition. The Freest-5D offers adjustable flow from 1-5L/min. Common prescriptions include 2L/min for mild COPD and up to 5L/min for severe respiratory conditions. Never adjust your prescribed flow rate without consulting your doctor.
What oxygen flow rate do I need for my condition?

The standard Freest-5D requires AC power to operate. We recommend having a backup battery pack or generator for emergency situations. Some models may offer optional battery packs for continued operation during brief power interruptions.

How loud is the Freest-5D during operation?
The Freest-5D operates at less than 45 decibels, comparable to a quiet library or soft conversation. This whisper-quiet operation makes it suitable for bedroom use without disturbing sleep.
Will my insurance cover the Freest-5D oxygen concentrator?
Many insurance plans, including Medicare, may cover oxygen concentrators when prescribed by a physician for medical necessity. Coverage varies by plan and requires proper documentation. Contact your insurance provider and request a Certificate of Medical Necessity from your doctor.
What is the warranty on the Freest-5D?
The Freest-5D typically includes a manufacturer warranty covering defects in materials and workmanship. Warranty terms vary by distributor. Extended warranty options may be available for additional coverage and peace of mind.
Can I use the Freest-5D with a CPAP machine?
While some patients use supplemental oxygen with CPAP therapy, this requires specific medical guidance and proper equipment setup. Consult your sleep specialist or pulmonologist before combining oxygen therapy with CPAP treatment.
