General Questions

How to choose the size of our mask?  

To find the correct size, you need to combine the two measurements below; the Weight Measurement and the Eye-Chin Distance Measurement.

WEIGHT MEASUREMENT
The weight measurement is strongly correlated with the length and size of the face, making it a great measurement for mask sizing.

Instructions:
1. Use a weight scale to find your weight
2. Compare your weight to the table below to find your size

EYE-CHIN DISTANCE MEASUREMENT
The eye-chin distance measurement is a very accurate method for getting the correct mask size.

Instructions:
1. Use a ruler and measure the vertical distance between your lower eyelid and your chin.
2. Compare your measurement to the table below to find your recommended size.

Mask Measurement (CM) Weight (KG) Eye-Chin Distance (cm)
XS 14 CM High x 19 CM Wide 30 and less 8.9 and less
S 15 CM High x 20.5 CM Wide 30 - 50 8.9 - 10.1

How to take care of the 3S Mask

 

3S Mask(s) can be used continuously as long as the built-in nano film isn’t damaged. The best way to care for your mask is by following the instructions below.

Q: What are the best ways to protect the Nano Filter and care for the mask?

A: Soak the mask in warm soapy water for 5 minutes and then gently rinse with water until clean (approximately one minute). Alternatively, place the mask in boiling water for one minute. Hang dry. Please avoid rubbing, twisting or squeezing the mask. Do not use a washing machine to wash the mask or you will risk potentially damaging the built-in Nano Filter.

Q: How many washes should a mask last?

A: As long as the care instructions are followed, a mask will last for a minimum of 50 washes. If proper care is not followed, the mask could be damaged in just one wash.

Q: How long does the water repellent, oil and soil resistant and antibacterial features remain effective?

A: These added protective features remain fully functionable for 30 washes. After 30 washes, the functions may slowly decrease.

Q: How long does the Nano Filter remain effective?

A: The Nano Filter is a mechanical filter that remains effective as long as the user does not damage the Nano filter material. The Nano filter will last for hundreds of hours if properly cared for.

Q: How often should the mask be washed once?

A: This is a personal preference but not a requirement. MFF-5 masks can be washed once a day or once a week or even once a month… Since the nano filter used on the mask is a mechanical filter, the filtration efficiency will not be affected due to length of uses.
