Why go portable

No tanks, no refills, no staying home

  1. 01

    Light enough to wear

    The Inogen One G4 weighs 2.8 lb and the Rove 4 2.9 lb, and both come with a carry bag.

  2. 02

    Hours of battery

    Listed battery life runs from under 2 hours to 8, depending on model and battery pack.

  3. 03

    Pulse or continuous

    Most portables deliver pulse dose. The Independence, Liberty2 and Zen-O can also run continuous flow.

  4. 04

    Cleared for flying

    The store says its portable units are FAA-approved for flight on most major airlines.

  5. 05

    Car and RV ready

    Portables can run in a car or RV, so golf, camping and the long drive are back on the table.

Home concentrators

Quiet, all-day oxygen for the home

Stationary concentrators plug into the wall and run through the night. The 5-litre units here cover flow rates up to 5 LPM; the two 10-litre machines go up to 10 LPM.

Six of the eight listings show a 3-year warranty. The two Drive DeVilbiss 5L listings show a 46 dB noise level instead.

Why this store

What comes with a new concentrator

As Oxygen Concentrator Store describes its service. A machine you depend on every day is only as good as the people behind it.

Since 2001

Run by American Medical Sales and Rentals in Centennial, Colorado, which says it has served more than 300,000 oxygen users.

Accredited

ACHC accredited since 2012, and an A+ rating with the Better Business Bureau, where it has been a member since 2010.

Specialists, 7 days a week

Respiratory staff factory-trained by CAIRE, Inogen, Respironics, SeQual and Invacare, with a US showroom and call center open 364 days a year.

Price match

A 100% price match guarantee is part of the store's Breathe Easy Guarantee.

Support for life

Technical support for the life of the unit, and a rapid replacement program if your machine needs repair.

Trade-in & buyback

Trade in or sell back the concentrator you already own when you move to a new one.

What customers say

4.8

out of 5 on Trustpilot, from more than 11,000 reviews

They know the machines

Reviewers keep naming the specialist who walked them through their options and matched a unit to their needs.

No hard sell

A common thread is being given time to decide, and being told what you need rather than what costs most.

Fast when it counts

Quick shipping, and quick fixes when something goes wrong, come up again and again.

Themes summarised from reviews on Trustpilot; figures as shown there in August 2026. Read the full reviews, including the critical ones, before you buy.

Before you buy

Six things worth knowing first

This is a large purchase for something you'll rely on every day. Here is what we found in the small print.

01

You'll need a prescription

Oxygen concentrators are prescription devices in the US. The store has a way to submit yours on its site.

02

Get the return window in writing

The store's own pages don't agree. The offer page says five days, the home page seven, and the returns page 14 days from receipt. Every return needs a Return Authorization first, and the store suggests insuring the parcel.

03

Read the coupon's wording

It's $500 off MSRP on a new unit. MSRP is the manufacturer's list price, and most prices here are already well below it, so ask exactly what the coupon takes off the price you're quoted.

04

Some prices are on request

The SimplyGo Mini and EverFlo Q list no price online, and several others show a price but no online checkout. Cards here say which is which.

05

Shipping from Colorado

UPS Ground is estimated at 3 to 5 business days, with 2-Day and Overnight options. It ships to all 50 states and four Canadian provinces, but not to APO/FPO addresses or US territories. A signature may be required.

06

Check with your airline

FAA approval doesn't replace your airline's own rules. Ask them what notice they need and how much battery to carry before you book.

Questions

Asked before buying

Pulse dose or continuous flow?

Pulse dose releases oxygen as you breathe in, which saves battery and keeps a unit small. Continuous flow delivers a steady stream, which some prescriptions need, often overnight, and those units are larger. Your prescription decides. Here, the Independence, Liberty2 and both Zen-O packages do both.

How does the $500 coupon work?

You claim it on the store's portable-concentrator offer page by signing up with your email. It's worded as $500 off MSRP on a new unit, and no end date was shown when we checked on 29 September 2026. Ask a specialist how it applies to the price you're quoted.

Can I rent before I buy?

Yes. The store rents portable and stationary units by the day, week or month, including the CAIRE FreeStyle Comfort, Respironics SimplyGo and SeQual Eclipse 5. It's useful for a trip, or while you decide.

Is a used unit worth considering?

It can bring the price down. The store sells used portable and home concentrators and runs a buyback program. Ask what warranty comes with the specific unit, as it may differ from new.

What happens if my machine needs repair?

The store lists lifetime technical support and a rapid replacement program for new purchases. Confirm how replacement works for your model before you order.

Can I pay over time?

The store offers a financing plan. Terms are set by the store and its finance partner, so check them on its site.
