Nanofiber three-ply filter with silver 3PLY FILTER nanosilver® (rectangle)- 2pcs in a package

- it can be used repeatedly (we recommend about 3-5x)

- it can be boiled at 80C for 20 minutes

- cannot be used if the inner nanofiber layer is damaged or broken

- 2pcs in a package

Nanofiber three-ply filter with silver 3PLY FILTER nanosilver®

without chemicals, adhesives and glues. Thin layer of nanofiber textile with firmly fixed molecules of colloidal silver is laminated between two layers of support and cover layer, specially developed for this application. Filters viruses and bacteria with efficiency of 92%. 

Filter construction consist of three-ply textile material, support and cover layers of non-woven PES viscosis and inner layer made of Polyamid 6 nanotextile with firmly fixed molecules of silver.

Functional nanotextile is made by endless fibre with the diameter 200 - 600 nm made by electro-spinning method with its basis weight of 3 g / m2. Cover layer has basis weight of 35 g / m2, overall basis weight of this membrane is 73 g / m2.

Size of SARS-CoV-2 virus particles is between 80-150 nm. The penetration of particles of this size through the filter material is around 8%, which confirms the filtration efficiency of 92%. The test was performed at a permeable speed of 10.7 cm / s.

Filter maintenance

RECOMMENDED TIME OF USE OF THE FILTER IN A MASK

Due to hygienic reasons, the 3PLY FILTER NANOSILVER® is designated for single use, meaning not to use multiple times before washing and heat treatment.. Its protective efficiency decreases with the quantity of filtered air; estimated time of maximum protection is 4 to 6 hours a day, with maximum lifetime of 3 to 5 days while following our recommendations. During work and sports activities the quantity of filtered air increases, thus reducing the filter lifetime. After the short-term use in the place with a higher rate of nearby persons (shopping, walks, etc. within the 1- to 2-hour time range) the reuse of the filter, due to its possible contamination by other persons, is ONLY recommended AFTER appropriate washing and heat treatment.

RECOMMENDATION FOR RE-USE

Remove the used face mask / neckerchief with the pocket for nanofilters with protective gloves or a microtene bag over your hands. Pull out the filter and insert it safely and carefully into the plastic bag marked as used filters. To maintain its functionality, it is necessary to keep an inner nanolayer intact! This can be easily checked by looking against the light, if the nanofiber layer is obviously broken, discard the filter.

Filter can be washed on 80°C for 15 minutes. Do not fold the filters during heat treatment, they must stay flat! Do not boil the filter above 80°C. Non-woven viscose material becomes brittle and breakable. We do not recommend heating the filters in a microwave, hot air or oven!
