For beginners, the process can feel strange at first. Your face may become wet, your vision may temporarily become blurry, and you may worry about water getting into your nose. With proper instruction and practice, however, mask clearing can become a manageable part of your diving skills.

In this guide, you will learn how to clear a partially flooded scuba mask, why the technique works, what to do if water remains inside, which mistakes to avoid, and how to practise safely before using the skill during a dive.

Important: This article is educational information, not a substitute for practical scuba training. Learn and practise mask-clearing skills in controlled water under the supervision of a qualified scuba instructor.

Quick Answer: How Do You Clear a Scuba Mask Underwater?

To clear a partially flooded scuba mask, keep your regulator in your mouth, continue breathing normally, gently hold the upper edge of your mask frame, tilt your head slightly upward, and exhale gently through your nose. The air helps push water out through the lower edge of the mask.

If water remains inside, check the mask seal and repeat the technique as instructed during your scuba training.

Do not rush, hold your breath, or make an uncontrolled ascent because your mask contains water.

What Is Scuba Mask Clearing?

What Is Scuba Mask Clearing

Scuba mask clearing is the process of removing water that has entered your diving mask while you are underwater.

A diving mask creates an air space in front of your eyes and covers your nose. Because the mask is not permanently sealed to your face, small amounts of water can enter around its silicone skirt.

This can happen when:

  • Your mask shifts during a dive.
  • Hair becomes trapped beneath the silicone skirt.
  • Your facial hair interferes with the seal.
  • A mask strap moves out of position.
  • Your mask does not fit your face correctly.
  • You accidentally bump or dislodge the mask.

Mask clearing allows you to restore your vision without immediately ending the dive, provided the situation remains manageable and you can follow your training safely.

PADI includes mask-clearing skills in entry-level scuba training because divers need to learn how to manage water inside their masks.

How to Clear a Scuba Mask Underwater Step by Step

The following explanation describes the basic partial-mask-clearing technique taught in recreational scuba training. Practise it with your instructor before attempting it independently underwater.

Step 1: Stay Calm and Keep Breathing

When water enters your mask, your first reaction might be to stop moving or rush toward the surface.

Instead, pause and focus on your breathing.

Keep your regulator in your mouth and breathe normally through it. Remember that water inside your mask does not automatically mean your breathing equipment has stopped working.

If you feel overwhelmed, signal your instructor or buddy and follow your training.

Step 2: Check the Mask Position

Make sure the mask is sitting correctly on your face.

If the mask has shifted, follow the adjustment technique taught by your instructor. Hair trapped beneath the silicone skirt can allow water to enter again, so check the seal whenever possible.

Avoid pulling the strap excessively tight. A comfortable, correctly fitted mask is more useful than one that presses painfully against your face.

Step 3: Position Your Hand on the Upper Mask Frame

Place your fingers gently against the upper portion of the mask frame, near your forehead.

The purpose is to help maintain contact between the upper mask edge and your face while you clear the water.

Do not press so hard that you distort the silicone skirt or make the seal worse.

Step 4: Tilt Your Head Slightly Upward

Raise your chin slightly and look toward the surface.

This positioning helps the air move toward the upper part of the mask while water escapes through the lower edge.

Your instructor can demonstrate the appropriate head position in the water.

Step 5: Exhale Gently Through Your Nose

With the mask positioned correctly, breathe out gently through your nose.

The air you exhale enters the mask and displaces the water. As the air expands into the mask, water is pushed out through the lower edge.

You do not need to forcefully blow all your air out at once.

Use a controlled exhalation, as demonstrated during training.

Step 6: Check Whether the Mask Is Clear

Once you have exhaled, check your vision and the amount of water remaining.

If the mask is clear, return to a comfortable breathing rhythm and continue monitoring your surroundings.

If water remains, check the seal and repeat the technique if you are comfortable and your instructor’s guidance allows it.

If the mask continues flooding or you cannot perform the skill calmly, signal your instructor or buddy and end the dive safely when appropriate.

Why Does Exhaling Through Your Nose Clear the Mask?

The technique works because air occupies space inside the mask and can displace water.

When you exhale through your nose, air enters the mask. With the upper edge held in position and the lower edge available as an exit, the incoming air pushes water out.

This is different from trying to remove water by inhaling through your nose or shaking your head.

The process depends on the mask’s position, a suitable seal and controlled exhalation.

Once you understand the basic principle, the skill becomes easier to remember during supervised practice.

Partial Mask Flooding vs Full Mask Flooding

Not every mask problem involves the same amount of water.

SituationWhat it meansGeneral approach
Small leakA little water enters around the mask skirtCheck the fit and use the clearing technique taught by your instructor
Partial floodingWater collects in the lower part of the maskUse the basic mask-clearing technique
Full floodingA large amount of water fills the maskStay calm, keep breathing through the regulator, and follow your instructor’s training
Mask displaced or removedThe mask no longer seals against your faceFollow the specific mask-replacement skills taught during your course

Fully flooding a mask and removing or replacing it underwater are different training skills. Do not attempt more advanced versions without appropriate instruction and supervised practice.

Common Scuba Mask-Clearing Mistakes

1. Panicking When Water Enters the Mask

Water around your nose and eyes can feel uncomfortable, particularly during your first few dives.

Sudden movements can make the situation more difficult to manage.

Practise slowly in controlled water until you become familiar with the sensation.

2. Forgetting to Exhale Through Your Nose

The technique relies on exhaled air entering the mask and displacing the water.

If you do not exhale through your nose, the water will not be cleared using this method.

Ask your instructor to demonstrate the technique if you are unsure about the timing.

3. Pressing Too Hard on the Mask

Excessive pressure can distort the silicone skirt or make it uncomfortable.

Use only the gentle pressure required by the technique you have been taught.

4. Ignoring Hair Beneath the Mask Seal

Even a small amount of hair caught beneath the mask skirt can cause repeated leakage.

Before a dive, position your mask carefully and check that its seal sits correctly against your skin.

5. Using a Poorly Fitting Mask

A mask that is too wide, too narrow or unsuitable for your facial shape may leak repeatedly.

Before buying a mask, check its fit according to the manufacturer’s instructions and ask a dive professional for assistance.

6. Rushing to the Surface

An unexpected mask problem does not automatically mean you should make an uncontrolled ascent.

Follow your training, maintain breathing through your regulator, communicate with your buddy and make an appropriate decision about ending the dive.

Never hold your breath during an ascent.

What Should You Do If Your Scuba Mask Keeps Leaking?

If water enters your mask repeatedly, the problem may not be your clearing technique.

Check these common causes.

Incorrect Mask Fit

A mask should rest comfortably against your face and form a suitable seal. Try different models if your current mask does not fit well.

Hair or Facial Hair

Hair beneath the silicone skirt can create a path for water to enter. Adjust your mask and check its seal before entering the water.

Incorrect Strap Adjustment

A strap that is excessively tight or poorly positioned may make the mask uncomfortable and interfere with its fit.

Adjust it according to the manufacturer’s instructions and your instructor’s guidance.

Damaged Silicone or Equipment

Inspect the mask for visible damage, worn silicone or problems with the frame. Replace damaged equipment when necessary.

Poor Mask Design for Your Face

Not every mask fits every face. A mask with a different shape or skirt design may provide a better fit.

How Beginners Can Practise Mask Clearing Safely

The best way to learn this skill is through structured practice with a qualified instructor.

Start in Controlled Water

Your instructor may begin in a swimming pool or another suitable confined-water training environment.

Controlled conditions allow you to focus on the technique without the additional challenges of currents, waves or poor visibility.

Practise One Step at a Time

Rather than trying to perform the entire skill perfectly on your first attempt, focus on the individual actions:

  1. Maintain normal breathing through your regulator.
  2. Position the mask correctly.
  3. Use the instructed hand position.
  4. Tilt your head as demonstrated.
  5. Exhale gently through your nose.
  6. Check the result.

Your instructor can correct your technique and help you progress at a suitable pace.

Communicate When You Feel Uncomfortable

Tell your instructor if you experience anxiety, have difficulty controlling your breathing or cannot comfortably perform the exercise.

There is no benefit in hiding a problem to finish the skill faster.

If you wear contact lenses or have concerns about water entering your eyes, discuss those concerns with your instructor before training.

Practise Until the Technique Feels Familiar

Repeating a skill under supervision helps you develop confidence and understand how to respond when water enters your mask during a dive.

Do not practise underwater mask-removal or other advanced mask skills alone.

Can You Clear a Scuba Mask Without Removing It?

Yes. A partially flooded mask can generally be cleared without removing it.

The basic technique involves positioning the mask, gently holding its upper frame and exhaling through your nose to displace the water.

Removing and replacing the mask is a separate scuba training skill. It is not necessary for every instance of mask flooding.

Is Scuba Mask Clearing Difficult?

It can feel challenging at first because your face becomes wet and your vision may be temporarily reduced.

Many beginners need several attempts before they feel comfortable.

The difficulty often comes from becoming accustomed to the sensation rather than from the physical movement itself.

A suitable mask, patient instruction and repeated supervised practice can help you become more comfortable.
