How to Change Anti-Fog Film

Have you ever been on a diving or snorkeling trip and could not keep your mask clear of fog? This is very common and is the #1 reason that people have a poor experience underwater.  We created the Tidal Mask to solve this problem and give you the best possible underwater visual experience so you can focus on enjoying the stunningly beautiful underwater world.

The Tidal Mask comes with an anti-fog film that is adhered to the inside lens. This magic film eliminates fogging by preventing small water droplets from forming on the lens. Fog is really just lots of tiny water drops that bend light and make it much more challenging to see. 

Watch the video above to see how our anti-fog film works in action. In this video, we have our proprietary anti-fog film adhered to the right lens, and the left lens is untreated tempered glass. We then use a ​steamer to simulate fog on the lens; the steamer produces far more fog and condensation than we do while snorkeling or diving.

With our anti-fog films, the Tidal Mask will not fog at all for the first few months and will perform much better than standard glass for months to years. 

We also offer replacement anti-fog films so if you do want to get your mask working like new again there are a few simple steps to change the film. Scroll down to learn more about how to change the anti-fog films on your own.

How To Replace the Tidal Mask Anti-Fog Films

Step 1:

First, peel off the old anti-fog film that is adhered to the inside lens. You may need to use your fingernail to get under the film. Lift it upwards and peel it off the lens.


Step 2:

Next, thoroughly clean the lens. You can use any standard glass cleaner or soap and water. Use a soft cloth (clean t-shirt works great) to dry and make sure there are no dust particles on the lens. Do not use paper towels or tissue paper as these can leave dust particles behind.

Step 3:

Prepare the new anti-fog film. Make sure to use the correct film for the correct lens. They are labeled left and right as if you are looking through the mask. The green tabs will be positioned on the top inside the lens (the bridge of the nose!)

Step 4:

Peel the new film off of the base layer. Make sure NOT to pull the green tab as this is a protective covering that will not be removed until the end. Tip: Try not to touch the adhesive side of the film if possible.

Step 5:

Carefully align the new film on the lens. Make sure there is a little space around the entire perimeter of the film before you let go! Once the film is in the proper position let go and it will adhere to the lens. 

Step 6:

Use a cloth to massage out any air bubbles. If the lens was fully cleaned you should be able to easily remove any bubbles after the application. 


Step 7:

Once you are ready to use your mask in the water, make sure to pull the green tab to remove the protective layer. Enjoy your fog-free Tidal Mask for months!


Tidal Mask Care Instructions

1: To Clean

Rinse the entire mask with fresh water after every use and let air dry. For best results use soapy water. If necessary, gently rub your finger on the inside lens with soapy water. Keeping your mask clean is the key to keeping the anti-fog properties working properly!


2: What Not To Do

Do NOT scrub, burn, scratch, or aggressively wipe the inside lens of your mask. You may gently rub the inside lens with soapy water to remove any stubborn salt or oil that is not removed by rinsing. 

3: Storage

Keep your mask stored inside the protective case when not in use. If you are storing for long periods of time make sure the mask is completely dry as excessive moisture can cause the film to degrade faster.
