Pure Oxygen, Delivered Reliably — At Home or On the Go
An oxygen concentrator pulls ambient air, filters out nitrogen, and delivers a continuous stream of concentrated oxygen — giving you a safe, cost-effective, and maintenance-friendly alternative to oxygen tanks. Whether you need supplemental oxygen at home, a quiet unit for overnight use, or a compact machine that travels with you, Optimal Breathing offers a carefully selected range of portable and stationary oxygen concentrators to match every need and budget.
A Range Built for Every Requirement
We stock oxygen concentrators across five output levels — 4 LPM, 5 LPM, 6 LPM, 7 LPM, and 10 LPM — so you get exactly the flow rate your situation calls for, without paying for capacity you don't need. Choose from machines across portable and stationary categories, from trusted brands including our own O2E2 line and Drive DeVilbiss, one of the most respected names in oxygen equipment worldwide.
Portable vs Stationary — Choosing the Right Type
Stationary Oxygen Concentrators
Designed for consistent, long-term home use. Our stationary units are lightweight, fitted with wheels for easy repositioning, and built for continuous operation. If your priority is reliable, uninterrupted oxygen delivery in a fixed setting — bedroom, living room, or wellness space — a stationary concentrator is your best choice.
Portable Oxygen Concentrators (POC)
Built for life on the move. Our portable concentrators are compact, travel-ready, and FAA-compliant for air travel. Lightweight enough to carry comfortably, powerful enough to deliver consistent output wherever you are. If you need oxygen therapy without being tied to one location, a portable concentrator gives you that freedom without compromise.
Continuous Flow vs Pulse Dose — Understanding the Difference
Oxygen concentrators deliver oxygen in one of two ways. Continuous flow machines deliver a steady, uninterrupted stream of oxygen regardless of your breathing pattern — making them the preferred choice for higher-demand use, overnight therapy, and stationary applications. Pulse dose machines detect your inhalation and deliver a burst of oxygen only when you breathe in, making them more energy-efficient and compact — ideal for active, on-the-go use where portability and battery life matter more than continuous output.
Both types are available across our range. If you are unsure which delivery method suits your needs, our team can help you decide before you buy.
5 LPM or 10 LPM — Which Output Do You Need?
Flow rate is the most common source of confusion when choosing a concentrator. Here is a straightforward guide:
- 5 LPM concentrators are budget-friendly, quieter, and well-suited for shorter sessions and individual home use. A practical choice if your oxygen needs are moderate and consistent.
- 10 LPM concentrators deliver higher flow for faster oxygen saturation, making them ideal for longer sessions, higher-intensity use, or situations where multiple users share a machine. They are built for heavier, more demanding use and offer greater long-term durability.
If you are unsure which output is right for your specific situation, our team is happy to guide you before you buy.
What Sets Our Oxygen Concentrators Apart
Competitive Pricing & Free Shipping
All oxygen concentrators ship free across the 48 contiguous US states. We offer competitive pricing across the entire range — from entry-level 5 LPM units to high-output 10 LPM machines — so you get maximum value without compromising on quality.
Universal Voltage Compatibility
All our machines are compatible with standard US power supplies. For international orders, we select machines that match your country's voltage requirements — no adaptors, no compatibility issues, no guesswork.
Quiet Enough for Overnight Use
Noise is a genuine concern, especially for overnight oxygen use. Most machines in our range operate at ≤50 dBA — quiet enough not to disrupt sleep. Our quietest unit operates at just 37.5 dBA, making it one of the most whisper-quiet concentrators available.
Industry-Leading Warranty
Most oxygen concentrators in our range come with a 3-year compressor warranty — significantly longer than the industry standard. That warranty reflects the build quality of every machine we stock and the confidence we have in the brands we carry.
Rigorously Selected, Not Just Listed
We do not simply list every machine available. Every concentrator we stock is selected for performance consistency, build quality, and reliability. We test what we sell.
Who Uses Our Oxygen Concentrators?
Our customers include individuals managing chronic health conditions, older adults seeking daily supplemental oxygen, wellness enthusiasts incorporating oxygen therapy into their routine, frequent travellers who need reliable portable oxygen, caregivers purchasing for a family member, and gym or wellness centre operators equipping their facility. Whatever your reason for needing an oxygen concentrator, we have a machine sized and priced for your situation.
