Setup and Sizing
1. Sizing Guide
Proper sizing is crucial for comfort and to prevent water leakage. The Easybreath mask is available in three sizes: XS, S/M, and M/L. To determine your correct size, measure the distance between the bridge of your nose and the bottom of your chin with your mouth closed:
- If the measurement is less than 10 cm (3.9 inches), choose size XS (Kids size).
- If the measurement is between 10 cm (3.9 inches) and 12 cm (4.9 inches), choose size S/M.
- If the measurement is greater than 12 cm (4.9 inches), choose size M/L.

2. Adjusting the Mask
- Place the mask on your face, ensuring the silicone skirt forms a seal around your face.
- Pull the adjustable elastic textile strap over your head. The strap is designed not to pull your hair.
- Adjust the four points of the strap (two on each side) to achieve a snug, comfortable fit. The mask should feel secure without being overly tight, which could cause discomfort or leakage.
- Ensure the snorkel is securely attached to the top of the mask.

Operating Instructions
Breathing Underwater
The Easybreath 500 mask allows for natural breathing through both the nose and mouth, similar to breathing on land. The dual air flow system facilitates continuous fresh air circulation, preventing fogging.
Dry-Top Release System
The mask is equipped with a "dry-top-release" mechanism in the snorkel. When submerged, this mechanism automatically seals the top of the snorkel, preventing water from entering the mask. This feature also prevents blocked breathing when encountering waves on the surface.
Anti-Fogging Technology
An exclusive patented design and air circulation concept prevent the formation of fog inside the mask. This system is similar to domestic extraction fans, ensuring a clear 180° panoramic view.
Safety Guidelines
- This mask is not suitable for free diving or intensive swimming. It is designed for surface snorkeling.
- The mask is not suitable for children under 10 years old.
- Always snorkel with a buddy.
- Be aware of your surroundings and marine life.
Maintenance
Cleaning the Mask
After each use, rinse the mask thoroughly with fresh water to remove salt, sand, and chlorine. Use a mild soap if necessary, but avoid abrasive cleaners or solvents that could damage the lens or silicone.
The included Micro Clean large microfiber cloth (6.6" x 5.7") is ideal for cleaning the mask's lens to ensure a clear view. Gently wipe the lens after rinsing and drying.
Storage
Store the mask in a cool, dry place, away from direct sunlight and extreme temperatures. It is recommended to store the mask in its original mesh bag to protect it from scratches and dust.

Troubleshooting
Mask Fogging
While the Easybreath 500 features an anti-fog system, some fogging may occur under certain conditions (e.g., significant temperature differences, improper fit). Ensure the mask is clean and free of residues. A thin layer of anti-fog solution can be applied to the inside of the lens if persistent fogging occurs.
Water Entry
If water enters the mask, check the following:
- Fit: Ensure the mask is properly sized and adjusted. A loose fit or facial hair (like a beard) can compromise the seal.
- Dry-Top System: Verify that the float mechanism in the snorkel moves freely and is not obstructed by sand or debris.
- Strap Adjustment: If straps loosen during use, re-tighten them. If a strap consistently loosens, inspect the buckle mechanism for damage.
Discomfort
If you experience discomfort, loosen the straps slightly. The mask should be snug, not tight. Ensure no hair is caught under the silicone skirt.
