CPSC Warning: OUSPT Snorkel Mask = Kaimana Mask from Germany

Updated: May 2026 · Sources: CPSC, SaferProducts.gov, Hawaii Snorkel Safety Study

On March 5, 2026, the US Consumer Product Safety Commission (CPSC) issued an official warning against the OUSPT full-face snorkel mask: stop using immediately — risk of breathing difficulty, unconsciousness, and drowning. 84,000 units were sold through Amazon in the US alone.

What many people don't know: it's exactly the same mask sold in Germany under the name Kaimana as a supposed Amazon bestseller. A generic 8-dollar product from China — just with a different logo printed on it.

CPSC Warning No. 26-311: Stop using the mask immediately. Dispose of it immediately. Do not resell or give it away.

What did the CPSC find?

The U.S. Consumer Product Safety Commission (CPSC) — the American equivalent of a national consumer protection agency in Europe — has published Warning No. 26-311. It addresses all owners of an OUSPT full-face snorkel mask with a clear message: stop using the mask immediately.

Normally, in such cases, the CPSC works with the manufacturer and organizes an orderly recall. What makes this case unusual: the manufacturer — a Chinese company called Field Life — did not respond to a single inquiry from the US agency. No statement, no cooperation, nothing. That's why the CPSC had to take the unusual step of issuing a public warning without the manufacturer's involvement.

The CPSC has received five consumer reports of breathing problems, dizziness, and loss of consciousness. In addition, there is a lawsuit alleging that the mask caused a death by drowning.

Why are these masks dangerous?

The CPSC cites three specific dangers:

1. Difficulty breathing and loss of consciousness

The mask can make breathing so difficult that the wearer loses consciousness. In the water, this is a deadly situation — anyone who becomes unconscious can no longer stay above the surface and drowns.

2. Elevated CO₂ levels (carbon dioxide rebreathing)

Stale air accumulates inside the mask. The carbon dioxide you exhale is not completely vented away and is partially breathed back in. This phenomenon is called rebreathing or CO₂ rebreathing. The result: headaches, dizziness, disorientation — and in the worst case, unconsciousness.

3. Fluid accumulation in the lungs (pulmonary edema)

Difficult breathing can lead to what's called ROPE (Rapid Onset Pulmonary Edema) — a sudden accumulation of fluid in the lungs. This is a medical emergency that is life-threatening even outside of the water.

Deaths and serious incidents worldwide

Hawaii: the epicenter

Between 2014 and 2023, 225 tourists and 62 residents drowned while snorkeling in Hawaii. The rise in deaths correlates directly with the growing prevalence of full-face masks starting in 2014:

  • 2010–2014: 82 snorkeling-related drowning deaths among visitors
  • 2015–2019: 114 snorkeling-related drowning deaths among visitors (an increase of approximately 39%)

A survey of 131 surviving snorkeling emergency patients found that 37% were wearing a full-face mask.

The Germany connection: OUSPT, Kaimana, and Alibaba

And here's where it becomes relevant for European consumers.

The Alibaba problem

The OUSPT mask is not a product developed in-house. It's a generic mass-produced item from China, available on platforms like Alibaba for around 8 US dollars per unit. Various brands buy these masks in large quantities, have their own logo printed on them, and then sell them as their "own product" — often for 30 to 50 euros.

Same mask. Different logo. The US government has classified the OUSPT mask as dangerous. Kaimana sells the same product in Germany — only with a different print. No TÜV. No SGS. No independent CO₂ test.
Direct comparison: OUSPT snorkel mask (CPSC warning USA) vs. Kaimana snorkel mask (Amazon bestseller Germany) — same mask, different logo

The component-by-component proof: why it's exactly the same mask

So far, we've claimed that OUSPT and Kaimana are structurally identical. But is that actually true? We checked.

To do this, we ordered an original Kaimana mask on Amazon.de and compared it component by component with the official product images of the OUSPT mask from the CPSC report. The result is unambiguous.

Source note: All OUSPT images are taken from the official report of the US agency CPSC. The Kaimana images were taken by us from an original purchased through standard channels on Amazon.de.

Comparison 1: breathing channel, valves, and frame

Component comparison 1: OUSPT and Kaimana snorkel masks in direct comparison — identical air intake, identical valve arrangement, identical frame

Markings *1 and *1.1: Identical air intake, identical valve arrangement, identical frame

In the upper area (markings *1 and *1.1), both masks show the same extremely narrow air intake. The valves are indistinguishable in arrangement, shape, and size. The frame, too, looks identical at first glance.

Comparison 2: silicone flap beneath the breathing channel

Component comparison 2: identical silicone flap beneath the breathing channel — only difference is a purely decorative cap

Markings *1.2 and *1.3: The same silicone flap — the green-highlighted area shows a purely decorative cap with no functional impact

Beneath the breathing channel (*1.2 and *1.3), both masks have the same silicone flap. The only visible difference: a small decorative cap, marked in green in the image. It is purely decorative and has no influence whatsoever on breathing behavior or valve function. We'll come back to this point in a moment — it's essential for understanding what's really going on here.

Comparison 3: exhalation valve, snorkel locking mechanism, and inner frame

Component comparison 3: exhalation valve, snorkel locking mechanism, quick-release buckle, and transparent inner frame — all components structurally identical

Markings *1.4 and *1.5: Structurally identical components in several places

This comparison (*1.4 and *1.5) reveals several matching elements at once:

  • Top right: the same exhalation valve — indistinguishable in design and positioning
  • In the snorkel: the same locking mechanism
  • Exhalation channel: the same unusually narrow passage
  • Bottom right: the same quick-release buckle in exactly the same spot
  • Inside: the same transparent plastic frame that joins the silicone to the mask body

Comparison 4: air valve, decorative fin, and mask top

Component comparison 4: purely decorative fin and uniquely designed air valve above the mouth and nose chamber — the most striking shared feature between both models

Markings *1.6 and *1.7: The most striking matches — decorative fin and uniquely designed air valve

Here, the most pronounced matches become visible (*1.6 and *1.7):

  • On top of both masks sits a purely decorative fin — identical in shape, position, and execution.
  • The air valve above the mouth and nose chamber doesn't exist in this specific form on any other snorkel mask we know of on the market. This unusual design is an unmistakable identifying feature.

Here too, the green circle marks only a decorative cap — it plays no functional role.

Why do only two parts differ? The answer: tooling costs.

Why did the manufacturer make even two tiny visual changes if the function remains 100% identical? The answer is straightforward economics.

Background — What is a "mold"? A mold is an injection mold: the tool used to produce plastic parts. A new mold costs on average around 5,000 US dollars. If you want to change the look of an existing product, you don't have to redevelop the entire product — you only have to adapt individual molds.

That's exactly what happened here. With an investment of just a few thousand US dollars, two purely decorative components (the elements marked in the green circles) were adapted. The rest — and thus all functionally relevant components such as the valve system, breathing channel, inner frame, quick-release buckle, and airflow routing — was carried over unchanged.

And why bother with this minimal change at all? Amazon. The marketplace's rules can merge two visually identical products under different brands or block listings. With this minimal design update, the Kaimana can be listed as a "standalone product" — but functionally, it remains the same model the CPSC explicitly warns against.

The supply chain closed: direct contact with the manufacturer

To close the loop completely, we have internal communications with the Chinese manufacturer whose product portfolio includes this mask model.

Excerpt from a WeChat communication with the Chinese manufacturer — both the OUSPT model and the structurally identical Kaimana variant are offered unbranded on the manufacturer's product page

Excerpt from a WeChat communication with the manufacturer — both mask variants are listed in the product portfolio

This excerpt confirms what the component comparisons have already shown: on the manufacturer's product page, both mask variants — the OUSPT and the Kaimana versions — are offered side by side. Both unbranded, ready for any reseller who wants to have their own logo and packaging printed on them. The purchase price: less than 8 US dollars per unit (approximately €6.88 — as of May 2026), including packaging and custom branding.

The full picture: The components are visibly identical. The manufacturer carries both variants in its portfolio. The only difference lies in two decorative plastic parts that have no effect on breathing behavior. Functionally speaking, the Kaimana mask is the same mask against which the US Consumer Product Safety Commission (CPSC) issued its Warning No. 26-311.

Kaimana: the same product under a German name

On Amazon.de, a full-face snorkel mask is sold under the brand name Kaimana that strikingly resembles the OUSPT model. Behind Kaimana stands hoodoo commerce GmbH, based in Hanover, Germany (HRB 220196).

What we know about the Kaimana mask:

  • No in-house development: The mask is not developed or improved by Kaimana — it comes directly from a wholesaler.
  • Alibaba standard model: The same base model is available on Alibaba for around 8 USD.
  • No independent CO₂ certification: No TÜV, no SGS, no DEKRA — no independent body has tested this mask's CO₂ levels.
  • Breathing channel too narrow: The central breathing channel is extremely narrow and even tapers down to roughly the diameter of a 1-cent coin. This increases breathing resistance and worsens the CO₂ problem.
  • Audible breathing noises: When breathing, a clearly audible whooshing sound is produced — a sign that the airflow is not being efficiently guided.
Kaimana snorkel mask — breathing channel too narrow compared to a 1-cent coin

The narrowed breathing channel of the Kaimana mask — barely wider than a 1-cent coin

The comparison: what distinguishes safe masks from unsafe ones?

Criterion OUSPT / Kaimana Safe full-face masks
CO₂ certification None TÜV / SGS / DEKRA certified
Breathing channel separation Insufficient / too narrow Real physical separation
In-house development No — Alibaba goods Own design & development
Factory price approx. 8 USD Significantly higher production costs
Manufacturer response None (OUSPT ignored the CPSC) Accountable contacts

For comparison — certified alternatives from Khroom: The Khroom Seaview Pro has an SGS-certified CO₂ test (test report), a breathing channel three times wider, and was developed in-house over more than five years. The Seaview Kids is TÜV Rheinland certified (test report).

What to look for when buying

If you own or are considering buying a full-face snorkel mask, watch out for the following points:

1. Independent CO₂ certification: Does the mask have a CO₂ test from an independent testing body? TÜV, SGS, DEKRA — anything that doesn't come from the manufacturer itself. If the manufacturer can't produce a certificate: stay away.
2. Real breathing-channel separation: Is there a physical barrier between the inhalation and exhalation areas? In cheap masks, stale air mixes with fresh air. In safe masks, there's a separate channel system with functioning one-way valves.
3. Check the origin: If the mask is available on Alibaba for 8 dollars and the seller can't show any in-house development — then you're paying for a logo, not for safety.
4. Protect children especially: Adult full-face masks are fundamentally unsuitable for small children — what matters is not the age but the body weight and lung capacity. If at all, only use models specifically developed for children and independently certified.
5. Take pre-existing conditions into account: Anyone with high blood pressure, heart problems, or respiratory conditions should be especially cautious or avoid full-face masks altogether.
Checklist: 5 points when buying a full-face snorkel mask — CO₂ certification, breathing channel, origin, children, pre-existing conditions
