How to Wear a COVID Mask Correctly?

Most mask failures happen in the first minute: a nose wire left un-molded, ear loops that slip, a chin that peeks out. The fix for each is simple once you know the sequence. Here’s the step-by-step method for putting on and taking off any mask, plus the fit checks that tell you it’s working.

What Does “Wearing It Correctly” Actually Mean?

A correctly worn mask creates a sealed barrier over your nose, mouth, and chin. The CDC’s guidance states that a good fit means no gaps, and you can check yours by cupping your hands around the mask’s edges to feel for escaping air. If fit is good, you’ll feel warm air through the front and see the material move as you breathe.

That seal is the whole point. Gaps at the nose bridge, cheeks, or sides let respiratory droplets enter and escape, which defeats the mask’s purpose. The World Health Organization (WHO) is equally direct: the mask must cover the nose, mouth, and chin, with no room for air to slip around the edges.

The Correct Order: Putting On and Taking Off

Both the WHO and CDC outline the same basic sequence, and the order exists for a reason — every step protects the next one.

Putting on:

• Clean your hands with soap and water or hand sanitizer.
• Inspect the mask for tears, holes, or damage. If it’s compromised, grab a fresh one.
• Identify the top (usually where the bendable nose wire is) and the inside.
• Place it over your nose and mouth, then secure the ear loops or tie the straps.
• Mold the nose wire firmly to the bridge of your nose with both hands.
• Pull the bottom edge down so it sits under your chin.
• Do a final check for gaps at the nose, cheeks, and sides.

Taking off:

• Remove it by the ear loops or ties only — never touch the front surface, which may carry virus particles.
• Lean forward slightly if instructed by a healthcare worker.
• Discard single-use medical masks in a trash bin immediately after removal.
• Wash reusable cloth masks after each use.
• Clean your hands right away.

One detail that trips people up: for surgical masks, the colored side faces out, the white or soft side touches your face, and the metal strip goes over the bridge of your nose. Wearing it inside-out looks the same at a glance but defeats the mask’s fluid resistance.

Five Mistake Patterns to Break

Fit problems rarely come from a bad mask — they come from habits. The most common failures are also the easiest to correct:

• Wearing it below the nose or under the chin. Both defeat the mask entirely; the nose and mouth must be covered at all times.
• Leaving gaps at the sides or cheeks. Tighten the ear loops or ties. Massachusetts DPH recommends knotting the ear loops or tucking excess material when a mask runs too big.
• Touching the front while wearing or removing it. Every touch risks transferring virus to your hands.
• Reusing a single-use mask. Medical masks should be discarded once they’re worn, wet, or dirty.
• Choosing a mask with a valve or vent. Valved masks let your exhaled breath escape unfiltered, which means they protect you but not the people around you. Official guidance from the CDC and Massachusetts DPH advises against them for public protection.

When a mask still doesn’t fit well after adjusting the straps, official public-health guidance supports fit-improvement methods like the knot-and-tuck technique (tying the ear loops and tucking the side excess inward) or adding a mask brace over the top. These improve the seal — but they don’t replace correct coverage in the first place.

Who Should Skip the Mask, and When to Swap It

Masks aren’t for everyone. The CDC-backed guidance says children under age 2 should not wear them, nor should anyone who cannot remove a mask without help or who has trouble breathing. In those cases, the right call is physical distancing and other protective measures instead.

Change your mask the moment it gets wet, dirty, or damaged — none of those conditions should be ignored. Cloth masks need a daily wash and dry, and they should be stored somewhere clean and dry between uses. The WHO also recommends keeping a removed mask in a clean plastic bag if you need to set it down, rather than on a tabletop or in your pocket.

One last habit worth building: the WHO advises cleaning your hands before putting a mask on, after taking it off, and any time you touch it while wearing it. A mask is only as good as the hands that handle it.
