If you’ve ever taken your GoPro in the ocean or other water, you might have noticed the lens fogging up. This can ruin all of your shots, and that’s never fun to find out when you go back and watch the footage!

The condensation is caused by differences in the temperature inside your GoPro case, versus outside of the case. It typically happens when you are in cold enviroments (in the ocean or snowboarding, for example).

GoPro solved this problem by producing anti-fog inserts, and they work great. They go around the side of your GoPro, in between the case and the camera.

The downside, of course, is the cost. The official GoPro anti-fog inserts cost around $15 for 12 inserts (usually you will use 2 of these inserts at once, and GoPro says they will last up to 4 uses).

So I’m going to show you how to make your own anti-fog inserts that will soak up any humidity in your GoPro case, preventing the lens from fogging up.

1. Cut several strips of paper towel, roughly 0.75″x3″. Any paper towel will work, but the thicker stuff does a better job.





2. Fold the strips into small rectangles/squares, and pinch them so they are flat.



3. Place the inserts between your GoPro and the case. I have a GoPro Hero 3, and I use 3 inserts. 1 on the top, 1 on the bottom, and 1 on the side by the WiFi button. You can use however many you want, and it might depend on what version of GoPro you have.



Make sure the inserts do not get in the seal of the case when closing the case.

Now go film something cool, without worrying about your lens fogging up!
