Why Does Fogging Happen Inside Your Underwater Housing?
Fogging occurs inside your underwater housing when warm, moist air comes into contact with the cooler interior surfaces, causing condensation. This lens condensation happens because the seal integrity isn’t perfect, allowing humid air to seep in or escape. When this moist air touches the cold lens or housing walls, water vapor condenses into tiny droplets, clouding your view. Even small breaches in the seal can lead to fogging, as they let in humid air that interacts with the cold surfaces inside. Temperature differences between your environment and the water also contribute, making it more likely for condensation to form. Ensuring the seal is intact and maintaining stable internal conditions are key to preventing lens condensation and keeping your gear fog-free.
Simple Steps to Prevent Fogging Before Your Dive
To prevent fogging before your dive, start by thoroughly cleaning your housing and lens with a lens cleaner or a mixture of water and a small amount of dish soap.
