If you or someone you love depends on oxygen, this message is important.

The truth is, not all oxygen concentrators are created equal. Some can even be dangerous.

Over the past year, a growing number of cheap, unbranded “oxygen concentrators” from China have appeared online through major retailers like Amazon and Google Shopping. These products are sold by Chinese-based companies that are not licensed medical suppliers in the U.S. and often fail to meet FDA and American medical safety standards. As a result, they’re flooding the market with low-quality devices that can put users’ health at risk.

The Problem: They’re Not Real Medical Devices

These knockoff machines are not FDA-cleared, and worse, they often don’t produce medical-grade oxygen at all. Many claim to deliver “oxygen therapy” or “high-flow oxygen,” but if you look closely—sometimes even in their own manuals—you’ll see shocking details. Some advertise oxygen purity levels as low as 30 to 40 percent, compared to the 90 to 95 percent purity required for medical-grade oxygen.

That means you could be breathing in room air, not true therapeutic oxygen, while believing you’re receiving proper treatment.

And because these devices fall into a gray area of consumer electronics, they can legally advertise online—even though they would never be approved for medical use in the United States.

No Support, No Warranty, No Accountability

It gets worse. If you try to contact these sellers, you’ll quickly discover that:

• The phone numbers don’t work or no one ever answers
• There’s no U.S.-based office or licensed oxygen provider behind them
• If something goes wrong, there’s no warranty or repair service available
• Once you pay, you’re completely on your own

Many customers only realize they’ve been scammed when their machine stops working—or worse, when they experience health issues from not receiving enough oxygen.

The Truth About These Sellers

Before you buy, here’s what you need to know:

• These companies are not licensed oxygen providers
• Their products do not meet FDA or U.S. medical safety standards
• Their marketing often includes false claims, fake reviews, and stolen product photos
• They target vulnerable people who rely on oxygen—especially seniors and caregivers looking for affordable options
• If something happens, you’ll never reach real customer service

It’s a heartbreaking situation that puts people’s health and safety at risk, all to make a quick sale.

Many of these devices explicitly state in their instructions and manuals that the equipment is not medical grade and not intended for medical use. (See below)

See the Proof for Yourself

We recently compared one of these cheap, unbranded “oxygen machines” against the Caire FreeStyle Comfort—one of the most trusted portable oxygen concentrators in the U.S. market. The results were shocking. The fake machine produced barely any oxygen, while the Caire FreeStyle Comfort consistently delivered medical-grade oxygen with every breath.
