Ultimate FAQ Guide To N95 Respirator Mask

More efficient than loose-fitting medical masks in keeping out small airborne particles, a tight-fitting N95 respiratory mask is the preferred choice of many.

N95 Respirator Mask

If you are a health worker, a caretaker of sick family members, or someone who is showing symptoms of dangerous viral diseases like the coronavirus COVID-19, you will benefit from wearing the N95 respiratory mask.

How Does The N95 Respirator Mask Work?

The N95 respirator mask achieves a close facial fit to block 95% of tiny (0.3 micron) airborne particles.

If you properly fit it over your face, the N95 respirator mask’s filtering capacities exceeds those of other face masks.

This video shows you how to wear a N95 respirator mask.

What Is A Surgical N95 Respirator Mask?

 Surgical N95 Respirator Mask

A surgical N95 respirator mask, also called the N95s, is a subset of the N95 filtering facepiece respirator category of surgical face masks used in healthcare settings.

It is tested for filtration efficiency (bacterial filtration efficiency and particulate filtration efficiency), fluid resistance, biocompatibility, and flammability.

If you are a medical professional or a patient, you are protected from the transfer of body fluids, particulate material, and microorganisms.

You should not reuse or share the surgical N95 respirator mask.

How Is The Surgical Mask Different From The Surgical N95 Respirator Mask?

Surgical Mask

A surgical mask, often called a face mask, is a loose-fitting disposal mask that is fluid resistant.

It offers you protection against large droplets, sprays or splashes of body fluids, respirator emissions, and other impurities.

The N95, on the other hand, fits tightly over your face and reduces exposure to small particle aerosols and large non-oily droplets.

Both the surgical mask and surgical N95 respirator mask create a physical barrier between the mouth and nose of the wearer and close-vicinity airborne contaminants.

However, the surgical mask does not seal your mouth and nose completely from the atmosphere.

The surgical N95 respirator mask, on the other hand, is designed to form an adequate seal around your mouth and nose.

When properly worn, leakages around the edges do not occur and most of the atmospheric air is directed towards the enclosed filter.

You can watch this video for a comparison between surgical masks and N95 respirator masks.

What Are The Major Differences Between The N95 And KN95 Respirator Masks?

KN95 Respirator Mask

The N95 and KN95 respirator masks are similar in many ways with small differences separating the two.

While the N95 respirator mask conforms to US FFR (Filtering Facepiece Respirator) performance standards, the KN95 respirator mask conforms to Chinese FFR performance standards.

Both the N95 and KN95 masks are certified for 95% filter performance efficiency.

Both are certified for 85L/min flow rates.

While the N95 respirator mask is not certified for total inward leakage (TIL) that is tested on human subjects as they perform exercises, the KN95 mask has a TIL arithmetic mean rating of ≤ 8 percent.

The N95 inhalation resistance at maximum pressure drop is ≤ 343 Pa, while the KN95 has a rating of ≤ 350 Pa.

The N95 mask exhalation resistance at maximum pressure drop is ≤ 245 Pa, while the KN95 is rated at ≤ 250 Pa.

The N95 respirator mask does not have a CO₂ clearance requirement, while it is ≤ 1% in the KN95 respirator mask.

Can Everyone Wear A N95 Respirator Mask?

Wearing the N95 respirator mask may cause breathing difficulties in people suffering from pre-existing medical conditions like chronic obstructive pulmonary disease (COPD), cardio/pulmonary problems, asthma, or emphysema.

Hence, if you have a serious respiratory condition, you may not be suitable to wear a N95 respirator mask.

How Do You Wear The N95 Respirator Mask?

Ensure that your nose and mouth are fully covered by the N95 respirator mask to prevent dust and mold from entering through the edges.

A practical way to check is to ensure the mask is in contact with your facial skin throughout.

If you have a beard or facial hair, it may not work properly.

Always hold the mask in place with both straps of the mask to prevent air from leaking around it.

This video shows you how to wear a N95 respirator mask properly.

How Do You Ensure That Your N95 Respirator Mask Fits?

Perform both positive and negative pressure checks (user seal checks) to check if you have correctly adjusted the mask on your face.

Use both your hands to adjust and readjust the nosepiece by running your fingertips along the cup over the nose on both sides.

Use both hands to adjust and readjust the straps or fasteners along the side of your head until you feel the mask form a seal on your facial skin in front.

· Positive Pressure Check

Without disturbing the mask’s position, cover it with both hands.

Exhale gently.

If the air leaks, you will feel it flowing outwards at the seal.

If the mask feels slightly pressurized there are no air leakages.

This is a successful positive pressure check.

As you exhale harder, air may escape through the sides of the mask.

Repeat to confirm the mask does not leak while you exhale gently.

The positive pressure check is performed only on N95 respirator masks without exhalation valves.

· Negative Pressure Check

Similar to the earlier check, cover the mask with both hands.

Inhale sharply.

You will feel the mask collapsing inwards at the center.

This is a successful negative pressure check.

It is not always possible to check both negative and positive pressure checks while you wear a N95 respirator mask.

You can follow the instructions found on the box that comes with your N95 respirator mask or as offered by your supplier.

This video shows you how to do a user seal check for an N95 respirator mask.

Conduct a visual inspection of the mask to determine its integrity.

Check to see if the nose bridge, nose foam, straps, and other components are not degraded.

Such degraded components can cause a loose face fit and seal, thereby reducing the N95 respirator mask’s effectiveness.

Perform a user seal check immediately after wearing the respirator.
