What Is a Portable Oxygen Concentrator and How Does It Work?
A portable oxygen concentrator takes the air in the environment around you, removes the nitrogen, and provides the purified oxygen through a nasal cannula. No tanks. No refills. No worry about running out mid-walk.
The best portable oxygen concentratorsfor sale are more than simply a medical equipment for those managing COPD, pulmonary fibrosis or other disorders needing supplemental oxygen; they are freedom. It means saying yes when your children invite you to dinner. It means getting on a plane without fear. It is to live life the way you want.
There are two basic delivery types and the wrong one is the single most often – and costly – mistake we see. Here’s what you should know.Read ourPortable Oxygen Concentrator Buyer's Guide to understand which type matches your prescription before you shop.
Pulse Dose vs. Continuous Flow: Which Type Do You Need?
Pulse Dose Portable Oxygen Concentrators
Pulse dosage units detect the precise moment you begin to breathe in and give you an accurate puff of oxygen timed with your breath. They're lighter, last longer on a single battery charge, and give you nothing between breaths. This makes them excellent for active daytime use, and travel. Most of the lightweight oxygen concentrators in this category are as little as 2.8 lbs.
Best for: Everyday wear, travel, active patients, and those that put weight and battery life first.
Important: Physician assistance is essential for pulse dosage during sleep.
Continuous Flow Portable Oxygen Concentrators
A continuous portable oxygen concentrator delivers a steady, uninterrupted stream of oxygen at a set liters-per-minute (LPM) rate — the same way home concentrators and oxygen tanks work. These units are heavier than pulse dose models, but they are essential for patients whose prescription specifies an LPM delivery rate, overnight or sleep use, or CPAP/BiPAP compatibility.
Best for: Sleep use, higher oxygen requirements, complex prescriptions, CPAP/BiPAP users.

5 Things That Actually Determine the Best Portable Oxygen Concentrator for You
There is no single 'best' unit, only the best unit for your situation. It’s what our Respiratory Therapists work through with every patient.
1. Prescription - pulse setting or flow rate in LPM.
Here’s the non-negotiable baseline. And that’s where everything else comes from. Bring your prescription when you visit any of our five Southwest Florida locations. If you don’t have it yet, call us and we’ll let you know what to ask your doctor.
2. The weight you can handle each day. Not just once.
On a tough day, the difference between a 6.3-lb unit and a 4.7-lb unit is real by mid-afternoon. It’s better to have a lightweight oxygen concentrator that you’ll use, than a heavier one that you leave at home. Be honest about your actual ability, not your best day.
3. Designed for Florida heat, battery longevity.
Manufacturer standards are tested in ideal conditions. In Southwest Florida summers use 70-75% of the claimed battery life. Stop by and let’s figure out real-world battery hours for your unique schedule and environment.
Flying domestically? All units we sell are FAA approved oxygen concentrators. International travel adds voltage compatibility and airline-specific paperwork. Cruising out of Fort Myers or Tampa? Call us before you book and we’ll run you through exactly what you’ll need at the gate and on board.
5. Hurricane season is a planning requirement, not an afterthought.
If you rely on powered medical equipment, you need a storm plan before a storm is called. That includes knowing your battery hours, your DC auto powers alternatives and your generator compatibility. Come in to any of our Southwest Florida locations in April or May and we will put together a real emergency plan for your individual unit and scenario. This is our one of our most essential conversations with our community.
Why Southwest Florida Trusts Medical Department Store for Portable Oxygen Concentrators for Sale
On Staff Licensed Respiratory Therapists
Not salespeople with a product card – licensed clinical personnel who can read your prescription, confirm the unit is delivering what your physician intended at your unique setting, and highlight mismatches before they cost you weeks of poor quality of life. That kind of clinical review doesn’t happen online.
Bring home any unit. Use it for 10 full days on your actual schedule — errands, grandkids, beach walks, everything. If it’s wrong for your real life, send it back and swap it. No restocking fee, no fine print, no waiting for a return package. No internet merchant can provide you with this.
Managed Direct Medicare Billing
We look over your coverage before you decide anything and tell you honestly what will qualify and what won’t. Bring your Medicare card and prescription when you come in, we’ll do the rest.
Service for All Brands and Models
All five Southwest Florida facilities service and repair all portable oxygen concentrators, no matter where you purchased yours. We can come to you if you are unable to come to our office.
Shipping & Expert Help, Nationwide
Not in Southwest Florida? We supply portable oxygen concentrators for sale to all 50 states, with the same expert pre- and post-purchase service by phone and email. You are never left alone after you buy.
Flying with an FAA Approved Oxygen Concentrator — What You Need to Know
All our units are FAA approved oxygen concentrators for use on domestic commercial flights. But FAA permission is just the beginning. Physician certification, battery life calculations, advance reporting to the airline, and airline-specific norms are among the additional oxygen requirements. International travel requires consideration of voltage compatibility.

Quick Travel Checklist for POC Users
Tips to Keep Your Lightweight Oxygen Concentrator Running Its Best
Your concentrator is a medical instrument of perfection. A few basic behaviors will make it last longer and keep you safe from unexpected failures – a particularly vital consideration in Southwest Florida, where heat and coastal humidity stress both filters and electronics more than in inland areas.
Wipe off the outside and examine your nasal cannula for wear. Change the cannula every 2–4 weeks.
Take out your external particle filter and flush it out, air dry well. Inland settings collect garbage slower than Coastal Southwest Florida. Don’t put a wet filter back in.
Warning Signs to Watch Out for in Progress
Signs of sieve bed breakdown include increased dyspnea and drifting pulse-ox readings – the most common reason a unit is delivering less oxygen than required even if it appears to beoperating normally. If anything feels odd, bring your unit in for a clinical output check. We test all brands at all five locations.
Frequently Asked Questions
Can I go to a portable concentrator and no longer use my home tanks?
Yes, for the appropriate patients and the proper units. For instance, continuous portable oxygen concentratorswith dual-mode like the OxLife Independence and CAIRE Eclipse 5 are made for continuous use including sleeping. Pulse dosage units usually are designed to be used just while you are awake, depending on your prescription and breathing pattern. Whether it makes sense to remove your home equipment in a single phone call or visit can be determined by our Respiratory Therapists based on your specific scenario.
Are portable oxygen concentrators for sale covered by Medicare?
Portable oxygen equipment may be covered under Medicare Part B with qualifying diagnosis and physician verification. We handle your Medicare billing, just give us a call before your appointment and we will check your coverage first so you know precisely what to expect before you make any decisions.
Are portable oxygen concentrators approved for plane travel?
All units we stock are FAA approved oxygen concentrators that are cleared for domestic commercial flights. Supplemental oxygen to be used on the flight must be approved by a physician, meet battery hour requirements, and be pre-notified to the airline, usually 48 hours in advance. International routes include voltage and carrier specific restrictions. Give us a call before you take your first flight on a new unit and we’ll walk you through it all.
Do you service concentrators that you didn't sell?
Yes. Every brand. Every model. No matter where you bought it. We service all portable oxygen concentrators at all 5 locations in Southwest Florida: Venice, Sarasota, Port Charlotte, Fort Myers and Naples. We also provide home service calls to patients who are unable to see us.
Can I take a unit home to try it out before I buy?
Sure. Our 10-Day No Risk Trial is exactly what it sounds like. Take any concentrator home, use it for 10 days on your actual daily schedule, and exchange it if it’s not right — no restocking fee, no fine print, no penalty. All five locations accept walk-ins, or call ahead for home delivery.
