Dangers of the snorkeling mask due to CO2 build-up
How dangerous are snorkel masks really? And what should you watch out for?
In 2018, American news outlets reported a dramatic increase in fatal accidents involving snorkel masks in Hawaii. Within a single month, ten people died – typically, there are around 17 deaths per year. What had happened?
Beware of cheap suppliers
According to reports, the cause was not snorkel masks in general, but cheap copies from Asia. These masks were often sold without tested safety standards. The producers remained anonymous, making quality control impossible.
The main issue was that these masks did not fully expel exhaled air. The result: CO₂ accumulates inside the mask and is inhaled again – leading to a dangerous carbon dioxide poisoning risk.
Users frequently reported foggy viewing windows – a clear warning sign.
A particularly alarming example is the Kaimana snorkel mask, which received many negative reviews on Amazon. Buyers complained about severely fogged lenses and poor air circulation – a clear sign of insufficient CO₂ ventilation. Such masks pose a serious risk and should be avoided.
Are snorkel masks generally dangerous?
Clearly not! The danger doesn’t come from the mask itself, but from untested, cheap products without a safe ventilation system. Reputable manufacturers like Khroom rely on thorough research and certified safety.
Khroom Seaview Pro – CO₂ safety at the highest level
The Seaview Pro by Khroom sets new standards in safety:

- ✔️ Unique valve system to prevent pendulum breathing
- ✔️ Extra-large air volume for effortless breathing
- ✔️ Extra-wide silicone frame for perfect fit and tight seal
The carefully designed airflow and one-way valves ensure that exhaled CO₂ is reliably expelled. This guarantees you always breathe fresh air – even on long snorkeling trips.
Our CO₂ test at a glance
In an internal comparison with four popular snorkel masks, the superiority of the Khroom Seaview Pro was clear:
While cheap no-name products showed levels over 9999 ppm (parts of CO₂ per million), the Khroom mask measured only 1600 ppm – a completely safe value, comparable to being in a well-ventilated room.
What should you look for when buying?
- ❌ Stay away from bargain products without recognizable safety labels or origin
- ✅ Look for real safety standards (e.g., DIN136)
- ✅ Read reviews – frequent fogging is a sign of poor air circulation
