Surgical Mask FAQs

Materials

Our surgical masks are made of polypropylene layers, nylon ear loops, and a metal nose wire. Our 3-layer surgical masks have 2 spunbond polypropylene layers surrounding an inner meltblown polypropylene filter layer. Our 4-layer surgical masks have 3 spunbond polypropylene layers surrounding an inner meltblown polypropylene filter layer. 

We are producing surgical masks under the current Emergency Use Authorization. You can see more information on the FDA’s website by clicking the links below.

Yes! Our surgical masks are medical grade/surgical grade and provide ASTM-level protection. 

Our masks are made without natural rubber latex. 

There is no fiberglass added to our surgical masks during any stage of production or processing. 

The spunbond polypropylene layers provide liquid barrier protection. The meltblown polypropylene layer provides the majority of the filtration properties of the mask. 

Our masks are made with a higher gsm (grams per square meter) polypropylene which gives them their softer, higher quality feel. Try them and you’ll see! 

Wearing

The pleats should point down on the side away from your face. The side touching your face should have the pleats pointing up. If your mask has a “WMS” on it, the WMS should be read correctly to an observer. 

Yes, they should be worn with the nose wire at the top and with the pleats pointing down on the side away from your face. They’re designed so that if liquid is sprayed at your face, the liquid would run off the mask and not get stuck in the pleats. 

Our masks are labeled for single use. The FDA has some excellent information about this which can be viewed by clicking here. 

You have a few options, you can twist the ear loops one or more times before wrapping around your ear. You can tie knots in the ear loops to shorten. If neither of these options work, please contact us! We have a youth/small ear loop mask model with the same size face mask, but shorter ear loops at 4.5″ each. These work well for those with smaller faces. 

You can try using a paper clip to relieve the pressure on your ears. 

There are no recognized tests that surgical masks can undergo to test for resistance to SARS-COV-2, the virus that transmits COVID-19. Please see the FDA and CDC website for their current recommendations. 

Testing

Yes! Our surgical masks have been tested to ASTM F2100-19 standards in USA labs. 

Models

Both models are made by us in Eau Claire, WI. They are both made of polypropylene. The 4 layer masks have 1 extra spunbond polypropylene layer that provides added liquid resistance. 

Our Adult and Youth masks have the same size face mask, but different length ear loops. Adult masks have 6.49″ long ear loops and the Youth masks have 4.5″ long ear loops. 

Our 4-layer masks are designed to be as breathable as our 3-layer masks. If you’re concerned about this, you can always try them out and we’ll refund you if you don’t like them. 

Packaging

Our masks are placed into either a plastic bag and sealed with a sticker or into sealed plastic bags. They are then sealed in tamper-evident boxes and packed in a cardboard shipper box to keep them safe on their way to your door. 

We do not currently offer other colors of our surgical masks. 

We do not seal each mask individually. 

Miscellaneous

We originally added an ultrasonic “WMS” mark to our masks to help the wearer easily identify which way to wear the mask. As we’ve grown and bought more machines, we’ve had to buy more ultrasonic “WMS” rollers. The ultrasonic rollers that place the “WMS” mark take 6-8 weeks to produce. We know that people need masks now so we cannot stop production and wait for them to arrive. Whether your mask has a “WMS” mark or not, if it’s in our packaging, it’s from us! 

The WMS mark should be read correctly by someone looking at you. The WMS mark should be backwards on the side touching your face. 

Some very eagle-eyed buyers have asked why the WMS on the mask on our boxes is on the right/left side while the masks they received had the WMS on the opposite side? In fact, the WMS mark on the masks on the box appear on both sides of the mask. Either way, it doesn’t matter whether the WMS is on the right/left/not there, if you have a mask in our boxes, it’s from us! 

This is not possible! Just ensure that the nose wire is at the top, and that the pleats point down on the side away from your face. If you think they’re backwards, flip them around! 

Some customers have noticed that different mask making machines sometimes weld the ear loops on the front of the mask versus the back side of the mask. The side where the ear loops are ultrasonically welded to the mask makes no difference to the protection or comfort of the mask. It’s simply a variation in mask making machines. 

N95 Mask FAQs

Materials

The N95 designation means they filter at least 95% of non-oil based particles. 

Filtering Facepiece Respirator

They are made of 4 layers of polypropylene. 

They are made in New Jersey, USA with material from Germany. 

There are no recognized tests that masks can undergo to test for resistance to SARS-COV-2, the virus that transmits COVID-19. Please see the FDA and CDC website for their current recommendations. 

Wearing

The side with the N95 markings should go on the outside. The side touching your face is all white with nothing printed on it. 

Our masks are labeled for single use. The FDA has some excellent information about this which can be viewed by clicking here.

These masks are meant to fit tightly around the head. If they are too loose please contact us. 

These masks are meant to be tight to provide an air tight seal. If you find they are too tight and uncomfortable for you, please contact us. 

There are no recognized tests that masks can undergo to test for resistance to SARS-COV-2, the virus that transmits COVID-19. Please see the FDA and CDC website for their current recommendations.

PPE - What Does it Mean?

Navigating Information Overload - We know you've had to learn a lot of new terms and information over the past few months. Here are some definitions that may help.

ASTM

American Society for Testing and Materials. They set forth standards for testing surgical masks and many other materials. 

ASTM F2100-19

F2100 refers to the specific set of standards set forth by ASTM International that govern the quality tests medical masks undergo. F2100-19 means the standards were updated in 2019. 

Bacterial Filtration Efficiency

Describes the filtration ability of masks when exposed to 3 micron size particles. F2101 describes how this is tested. Abbreviated as BFE. 

Differential Pressure

The pressure drop across a mask which corresponds to the breathability of a mask. Tested according to EN 14683. Abbreviated as Delta P. 

FFR

Filtering Facepiece Respirator

gsm

Grams per square meter. This is what we use to describe the thickness of the polypropylene in our masks. 

Liquid Barrier Protection

Describes the ability of a mask to resist liquid penetration through the mask. This mimics infectious liquids shooting at the mask. It is tested at 3 different pressures which mimic blood pressure at different velocities. 80mmHg represents venous blood pressure, 120mmHg represents arterial blood pressure. 160mmHg represents very high blood pressure which can escape in trauma situations. 
ASTM F1862 describes how this is tested. Also referred to as resistance to penetration by synthetic blood. 

meltblown polypropylene

Polypropylene in a meltblown configuration. This layer provides the filtration properties of masks. 

N95

N means non-oil based particles. 95 means it filters 95% of those non-oil based particles. 

NIOSH

The National Institute for Occupational Safety and Health

particulate filtration efficiency

Describes the filtration ability of masks when exposed to 0.1 micron particles. ASTM F2299 describes how this is tested. Abbreviated as PFE. 

polypropylene

A versatile textile material made of plastic polymers. This is used to make the layers of medical masks. Abbreviated as PP. 

PPE

Personal Protective Equipment.
Includes surgical masks, N95 masks, face shields, etc. 

Resistance to Penetration by Synthetic Blood

Describes the ability of a mask to resist liquid penetration through the mask. This mimics infectious liquids shooting at the mask. It is tested at 3 different pressures which mimic blood pressure at different velocities. 80mmHg represents venous blood pressure, 120mmHg represents arterial blood pressure. 160mmHg represents very high blood pressure which can escape in trauma situations. 
ASTM F1862 describes how this is tested. Also referred to as resistance to penetration by synthetic blood. 

Spunbond polypropylene

Polypropylene in a spunbond configuration. These layers surround the meltblown filter layer and provide the structure of the mask. They provide liquid barrier protection. 

Surgical Mask

A medical device used to create a barrier between the wearer and the outside environment. It should cover the mouth and nose when worn properly. Click to view more information on FDA.gov.
