PLEASE NOTE: We are removing the optional neck strap with the mask. Almost all of our customers told us they prefer to wear the mask with just the ear loops because they are so comfortable!  Additionally, wearing the mask without the neck strap increases the longevity of the elastic ear loops.


Measure the distance between earlobes by going directly under the nose.

SilverTek is a leading health tech company based in Greenwich, Connecticut. The NanoFit Mask is an FDA-listed mask. Made with excellence in South Korea.


  • SilverTek’s NanoFit Mask leads the market in cutting-edge face mask design.
  • The NanoFit Mask’s sleek, proprietary design is optimal for comfort, fit, breathability, and long term wear.
  • The adjustable nosepiece is cushioned inside a proprietary fabric blend so it forms specifically to the wearer’s face. As a result, the mask does not gap or fog glasses.
  • Ergonomic earloops are light and comfortable for daily use.
  • The NanoFit is available in six sizes, creating an optimal fit for every face.


  • The SilverTek NanoFit Mask is treated with award-winning Polygiene ViralOff®.
  • ViralOff® is scientifically proven to reduce germs on the mask fabric by 99% within two hours.
  • This antimicrobial treatment protects the mask, therefore reducing the need to wash it. 
  • ViralOff® is made with recycled silver and is completely safe on the skin.


  • The NanoFit Mask’s 4-layer replaceable filter utilizes nanofiber filtration technology.
  • It blocks micro-pollutants as small as 0.3 μm.
  • Unlike traditional filters, nanofiber does not depend on static electricity to filter effectively. As a result, nanofiber filters last significantly longer.
  • Nanofiber filters maintain their effectiveness in humid conditions, such as rain, sweat, and condensation from breathing.
  • The NanoFit Mask combines layers of both nanofiber and traditional filtration to provide optimal protection.
  • Our electrospun nanofiber is better than meltblown filters in regards to consistent fiber size, comfort, and breathability.

Best fitting

by far of all the masks I have worn best fitting and most comfortable. I feel better protected with this mask than any other one I have used. Thank you for producing such a valuable product during these troubling times.

Perfectly safe

It’s the only mask I’ve tried in a year that makes me feel both perfectly safe from the great fit and comfortable from the soft and light fabric. SilverTek also has great customer service who immediately responded to a question in a very professional manner.

Everyone should have one of these!

I love this mask! It’s light, comfortable, and reassuringly safe with the anti viral technology. I’m spreading the word! Everyone should have one of these!

Great quality

I have been very impressed with not only the quality of my mask, but the great customer service they provide. It is a well constructed mask that I purchased for myself, my wife, and both of my parents. At the time of this review, we've been using these for the better part of 6 months and have really enjoyed the experience.
