If you’ve started looking into supplemental oxygen for yourself or a parent, you’ve probably already run into the Philips name more than once — on prescriptions, in hospital supply rooms, on nearly every comparison list a pulmonologist hands out. But “Philips oxygen concentrator” isn’t one machine, it’s a whole family of them, built for different situations. This guide walks through the three models Philips Respironics is best known for — the EverFlo, the SimplyGo, and the SimplyGo Mini — so you can see how they differ before deciding which one actually fits your routine.

Philips Respironics: A Legacy Built Around Breathing
Respironics started in 1976 as a small manufacturer of anesthesia masks near Pittsburgh, and within a decade it had developed one of the first nasal CPAP systems for treating sleep apnea. That early focus on respiratory therapy never really changed — the company expanded into bi-level ventilation, home ventilators, and oxygen concentrators, building a reputation among pulmonologists well beyond CPAP. Philips acquired Respironics in 2008, and the combined company has since supplied more than three million oxygen concentrators to patients worldwide.
That history matters when comparing an Oxygen Concentrator Philips model against a lesser-known brand, because it shows up in the engineering, not just the marketing. Philips concentrators tend to share a few consistent traits: an internal oxygen sensor that monitors purity in real time, alarms that flag performance drifting outside a safe range, and a parts and service network that’s genuinely easy to find in India. Whether you land on the EverFlo, the SimplyGo, or the SimplyGo Mini, you’re getting the same design philosophy — flow type, weight, and battery capability are really what separate the three.
How an Oxygen Concentrator Works (and Why the Model You Pick Matters)
An oxygen concentrator doesn’t store oxygen the way a cylinder does — it pulls in ordinary room air (roughly 78% nitrogen and 21% oxygen) and runs it through a filtration process called pressure swing adsorption. Zeolite mineral beds trap nitrogen while letting oxygen pass through, delivering a concentrated stream of medical-grade oxygen through a nasal cannula. Because it’s only “concentrating” air already around you, it never runs out the way a cylinder does — as long as it has power, it keeps producing oxygen.
Where models genuinely diverge is in how that oxygen gets delivered, and that’s the piece most first-time buyers underestimate:
- Continuous flow delivers a steady, uninterrupted stream of oxygen at a fixed rate, regardless of breathing pattern — generally needed for higher oxygen requirements, nighttime use, and shallow or mouth breathing.
- Pulse dose (demand flow) senses the start of each inhalation and releases a measured bolus of oxygen only when you breathe in, conserving oxygen and battery life between breaths. It suits many ambulatory patients but isn’t right for everyone, particularly during sleep or at extreme prescribed flow rates.
This single distinction — continuous flow versus pulse dose — is really what separates the EverFlo, SimplyGo, and SimplyGo Mini, more than any other spec on the page.
Philips Respironics EverFlo: The Stationary Oxygen Concentrator for Home Use
The Philips Respironics EverFlo is the brand’s flagship stationary unit, and it’s the one most commonly recommended when a doctor prescribes a straightforward Oxygen Concentrator for home use. It isn’t designed to be carried around — it’s meant to sit in a bedroom or living room, plugged into a wall outlet, running for extended stretches without much fuss.
The EverFlo delivers continuous flow oxygen across a range of roughly 0.5 to 5 LPM, with oxygen concentration rated at 93% (±3%) at the higher flow settings. It weighs around 31 lbs (about 14 kg) and measures approximately 23 x 15 x 9.5 inches — substantial, but manageable to reposition on its integrated casters. Philips built in a recessed flow meter and metal cannula connector to reduce accidental breakage, a practical detail for a machine meant to run daily for years. Power draw sits around 350W, and Philips rates the unit at 45 dB or below — quiet enough for a bedroom corner overnight.
What really sets the EverFlo apart clinically is its built-in OPI, or Oxygen Percentage Indicator — a sensor that continuously checks purity and flags the unit if levels drift outside the acceptable range. For a device patients may depend on for eight, twelve, or twenty-four hours a day, that self-monitoring is a meaningful safety feature. Philips backs the EverFlo with a standard 3-year warranty.
If your prescription calls for a fixed, dependable continuous flow rate and the machine isn’t going to leave the house often, the EverFlo remains one of the most trusted choices in the Philips lineup.

Philips SimplyGo: Continuous Flow and Pulse Dose in One Portable Unit
The Philips SimplyGo occupies a middle ground that very few portable concentrators cover — it offers both continuous flow and pulse-dose delivery from the same device, making it one of the more flexible portable oxygen concentrators on the market. That flexibility matters for patients whose oxygen needs vary through the day, or who need continuous flow for sleep but want a lighter option for daytime activity.
On continuous flow, the SimplyGo delivers 0.5 to 2 LPM in 0.5 increments. On pulse dose, it offers six settings with bolus sizes ranging from about 12 ml at setting 1 up to roughly 72 ml at setting 6, and it can toggle into a dedicated sleep mode. Oxygen concentration is rated between 86% and 97% depending on the setting. The unit weighs around 10 lbs, runs at approximately 42 dB, and Philips has approved it for use on commercial flights — a meaningful consideration if travel is part of the picture.
Battery performance is where the trade-off between flow modes shows up: a single battery lasts roughly three hours on pulse setting 2, but only around 0.9 hours on continuous flow at 2 LPM, since continuous flow draws far more power. Patients who need continuous flow on the go typically pair the SimplyGo with an extended battery or plan around AC/DC charging rather than relying on battery alone for a full day out.
In practice, the SimplyGo suits patients who need genuine continuous flow support but also want to leave the house, travel, or move between rooms without hauling a stationary unit like the EverFlo along. Full specifications and included accessories are on the SimplyGo product page.
Philips SimplyGo Mini: The Lightest, Most Compact Option for Travel
The Philips SimplyGo Mini is built for one job above all others: going anywhere with minimal weight and bulk. It’s pulse-dose only — no continuous flow setting on this unit — which keeps the internal components smaller and lighter, but also means it isn’t the right fit for patients whose prescription specifically requires continuous flow.
At just 5 lbs with the standard battery (6 lbs extended), the SimplyGo Mini is noticeably lighter than the SimplyGo, with a footprint of roughly 8.3 x 3.6 x 9.4 inches — small enough for a shoulder bag. It offers five pulse-dose settings, oxygen concentration rated between 87% and 96%, and a color touchscreen LCD for adjusting flow and monitoring battery status. Noise stays low across settings, typically in the low-to-mid 40s dB range.
Battery life is one of its strongest selling points: up to 4.5 hours on the standard battery and up to 9 hours extended — enough for many active users to cover a full day without recharging. Like the SimplyGo, it’s FAA-approved for commercial flights, with a 3-year warranty on the concentrator and a 1-year warranty on the sieve beds.
For patients who are largely independent, don’t require continuous flow, and want the smallest possible device to carry through airports or between appointments, the SimplyGo Mini is usually the model worth starting with, assuming a physician has confirmed pulse dose is appropriate for the prescribed flow rate. See the full spec sheet on the SimplyGo Mini product page, or compare it against other portable models in our portable oxygen concentrator category.

Which Philips Oxygen Concentrator Should You Choose?
The honest starting point is always your physician’s prescription — whether it specifies continuous flow, pulse dose, or either, and at what LPM. From there, mobility needs narrow it down further.
| Your Situation | Likely Best Fit | Why |
|---|---|---|
| Prescribed continuous flow, spends most of the day at home | Philips EverFlo | Covers up to 5 LPM continuous flow reliably, built for long daily runtime on mains power |
| Prescribed continuous flow but wants to move between rooms or travel occasionally | Philips SimplyGo | Only model here offering true continuous flow in a portable, battery-capable form |
| Prescribed pulse dose, active lifestyle, frequent outings or flights | Philips SimplyGo Mini | Lightest and smallest option, longest battery life relative to its size |
| Needs a night-time unit plus a lightweight daytime unit | EverFlo (night) + SimplyGo Mini (day) | Many households pair a stationary unit for sleep with a portable one for errands and travel |
| Unsure whether pulse dose will feel like “enough” oxygen | Start with SimplyGo (offers both modes) | Lets a physician or therapist trial pulse dose against continuous flow on one device |
These three models aren’t mutually exclusive within one household — a fair number of patients keep an EverFlo bedside for overnight continuous flow and a SimplyGo Mini in a bag for daytime independence.

Oxygen Concentrator Price and Rental: What Actually Drives the Decision
Oxygen Concentrator price naturally varies with the model, flow type, battery configuration, and whether you’re buying new, buying certified pre-owned, or renting. Rather than quoting figures that change with supply, here’s what actually moves the number:
- Flow type — continuous flow and dual-mode units like the SimplyGo generally involve more internal hardware than a pulse-dose-only unit like the SimplyGo Mini.
- Battery configuration — an extended battery adds runtime but also adds to the overall package.
- New versus certified pre-owned — pre-owned units offer Philips build quality at a different point on the spectrum, provided they’ve been properly serviced and tested.
- Purchase versus rental — for short-term recovery or a visiting family member, renting avoids a large upfront commitment.
If your need is likely temporary — post-surgical recovery, a short-term flare-up, or a visiting relative — renting is usually the more sensible route, letting you try the EverFlo, SimplyGo, or SimplyGo Mini in real daily use before deciding whether to buy.

Frequently Asked Questions
What’s the main difference between the Philips EverFlo, SimplyGo, and SimplyGo Mini?
The EverFlo is a stationary, mains-powered unit for home use with continuous flow only, up to 5 LPM. The SimplyGo is portable and offers both continuous flow (up to 2 LPM) and pulse dose. The SimplyGo Mini is the lightest and most compact of the three but offers pulse dose only.
Can the SimplyGo Mini be used for continuous flow oxygen therapy?
No. The SimplyGo Mini is pulse-dose only. Patients whose prescription requires continuous flow should look at the EverFlo for home use or the SimplyGo for a portable continuous-flow option.
Is the Philips SimplyGo approved for use on flights?
Yes. Both the SimplyGo and the SimplyGo Mini are FAA-approved for commercial aircraft, which is one reason they’re commonly chosen by patients who travel. The EverFlo is a stationary home unit not intended for portable or in-flight use.
How long does the battery last on the SimplyGo Mini compared to the SimplyGo?
The SimplyGo Mini’s standard battery runs up to roughly 4.5 hours, extending to about 9 hours with the extended battery. The SimplyGo’s battery life depends on the mode: roughly 3 hours on pulse setting 2, but under an hour on continuous flow at 2 LPM, since continuous flow draws considerably more power.
Do I need a doctor’s prescription to buy or rent a Philips oxygen concentrator?
Reputable suppliers generally require documentation of your prescribed flow rate and delivery mode before dispensing an oxygen concentrator, since the wrong mode or rate can under- or over-deliver oxygen.
Which Philips oxygen concentrator is best for home use with heavier oxygen needs?
The EverFlo is generally the go-to choice for an Oxygen Concentrator for home use where the prescribed flow is on the higher end, up to 5 LPM, and the unit will mostly stay in one place.
Can I use an EverFlo and a SimplyGo Mini together in the same household?
Yes — a common setup. Many patients use a stationary EverFlo overnight or at home, then switch to a lighter portable unit like the SimplyGo Mini for outings and travel.
Does a higher pulse-dose setting mean more oxygen is delivered?
Yes. Pulse-dose settings on the SimplyGo and SimplyGo Mini control the bolus, or volume, delivered per breath — higher settings mean a larger bolus, so the setting should be confirmed against your prescribed flow equivalent rather than chosen by feel.
