How to recognize a CO₂-safe snorkel mask

1. Certifications and Safety Standards

Make sure the mask is truly CO₂-safe. Beware of false claims! Especially on Amazon, many Chinese sellers advertise their masks as CO₂-safe – but without proof or proper testing.

All snorkel masks from Khroom are tested according to DIN136 and meet the highest safety standards. The Seaview Pro in particular features a unique valve system that prevents pendulum breathing and ensures healthy air circulation.

2. Size and Fit

A poorly fitting mask can lead to air escaping or improper circulation. That's why it’s important to choose a mask that fits your face well.

Tip: Follow the manufacturer's size guide and ensure that no air is felt near the eyes when exhaling. Feeling airflow while inhaling is normal, but if you feel it while exhaling around the eye area, it’s a sign the silicone frame isn’t sealing properly between the eye region and the mouth-nose chamber.

That’s why the Seaview Pro by Khroom is equipped with an extra-wide silicone frame. This ensures a perfect seal and prevents air leakage in critical areas.

3. Reviews and Testing

Read product reviews carefully. If you see frequent mentions of a fogged-up lens, avoid the product. Poor air circulation is not only frustrating but may also be a sign of faulty CO₂ venting.

One example is the Kaimana snorkel mask on Amazon:
