Product detailed description

The extremely dense nanofiber membrane in the nano filter can capture the most common biological threats to human health currently known, such as viruses, dust, allergens and smog. The disposable filters are made of nanofiber material with an efficiency of 98.69%.

Benefits of Nano Filters for Masks - YourFILTER:

  • An economical alternative,
  • tested effective capture,
  • nanofiber membrane,
  • suitable for all types of masks with a pocket size of 18 x 9 cm.

Disadvantages of Nano Filters for Masks - YourFILTER:

  • The overall filtering ability is always dependent on the tightness of the drape used.
  • Need to be changed after 2-6 hours.

How Does the Nano Filters for Masks - YourFILTER Work?

The nano filter is made of a barrier nanofabric that works on the principle of a mechanical barrier. This means that the size of the holes in the nanofiber membrane is so small that a virus, bacteria or other sub-micron particles will not pass through.

How Long Can I Use One Nano Filter for?

The effectiveness of the filter decreases with wear time, providing optimal protection for 2-6 hours. Once the filter gets wet, it loses its ability. The wear of the filter depends on the intensity of breathing, for example during sports or high-intensity activities we recommend changing it after 2 hours.

How Do I Know if the Filter in the Mask Is Ineffective?

As soon as you feel that it is harder to breathe in your filter mask, it is a sign that the filter is clogged. At that point, we recommend replacing the filter.

Instructions for Inserting the Replacement Nanofilter YourFILTER into the YourPOCKET Mask:

  1. Cut out an 18×16 cm rectangle from an A4 sheet of paper and fold it to 18×8 cm. Next, ideally wear sterile protective gloves, or use an alcohol-based disinfectant or wash your hands with soap and water.
  2. Insert the 18×9 cm YourFILTER into the resulting paper sheet.
  3. Grasp the folder where the paper is folded and, with the side of YourFILTER protruding, insert the entire folder into the YourPOCKET mask.
  4. Grasp the folder where the paper is folded and, with the side of YourFILTER protruding, insert the entire folder into the YourPOCKET mask.
  5. Hold YourFILTER over the YourPOCKET mask at the point where it protrudes from the paper folder and pull the folder out without YourFILTER. You can use the folder in the next exchange. YourFILTER is inserted and YourPOCKET is ready for use.

Nano4Health (N4H) is a brand of Sen World, which has been producing protective equipment based on nanotechnology since 2014. The development and production of aids takes place in the Czech Republic, products are regularly tested in the American company Nelson Laboratories.

How do N4H products work?

N4H's main products are disposable textile masks and disposable filters woven from nanofibers with a diameter one-thousandth of a human hair. The structure of the material is so dense that bacteria, viruses or any other pathogenic particles cannot pass through it. The degree of filtration corresponds to this – 99.9%.

Some disposable masks and N4H inserts are additionally enriched with silver nanoparticles, which actively eliminate microorganisms caught on the masks and (in the case of bacteria) prevent their further reproduction.

Disposable filters are placed in the pocket of a cotton mask and replaced after a few hours of wear.
