Dear clients,

in order to answer your frequently asked questions in the shortest time possible, we have prepared this list together with the answers.

We would like to give you some insight into the last few months of our Virus Killer production.

Update – 3/6/2020

In good faith, and probably in our naivety at the time, in February 2020, we decided to accept the challenge and give our Virus Killer product, which we originally wanted to launch by the end of 2020, to people when they needed it the most. Unfortunately, due to reasons described below, we still haven’t been able to make it happen. We are very sorry about this situation. We informed our customers about the state of affairs, gave our explanation and started to return the money that we had accepted for pre-orders already before the date of the first announced pre-order delivery of the VK to the client. Because it was a matter of health protection, we equipped interested clients with another type of respiratory protective equipment.

The restrictions connected with the coronavirus pandemic across Europe and around the world still persist. Because of them, many business situations become unclear and unpredictable. Although you may not be able to imagine this completely, all you have to do is think about how significantly your life has changed recently. Any restrictions in the business environment have a more intense and long-term impact. We have been operating on the international market since 2013, respiratory protection products are just one range of products of our nanofiber filter and membrane portfolio. Today, however, "the whole world makes face masks." As a result, there is an extreme demand on the international market for materials intended for the production of various types of protective equipment, and at the same time, there are still various regulations in place which make it necessary to prioritize supplies e.g., to producers in a given country. This situation also affects us and causes a very long waiting period, not only for the materials. Original agreements, deadlines, or possibilities suddenly don't apply, and we can't work reliably with any real schedule. As a result, we, too, are forced to constantly optimize and adapt to the current situation with the maximum use of available resources. We learned from how the plans communicated by us were turned against us in the media, which is why we now want to be much more cautious. We will not announce specific dates in advance or inform our clients in detail about our new products, we will do that only after they are available for purchase so as not to expose ourselves to media lashing which consumes a lot of our energy in situations we can't control.

For all these reasons, we have decided to start selling the new Virus Killer product line at the end of this year. So, we are returning to our very original plan for the VK line launch. We want to have sufficient time to implement all the steps connected with the launch. It is true that we will produce VK products in the Technology Park in Brno. We are proud that under the given conditions, when restrictions connected with the coronavirus are not only about limiting people’s freedom of movement, but about limiting the free movement of everything, we managed to acquire a production line and transport it to the Czech Republic. It is now installed in the Technology Park and is in its testing phase. Before we can start the production of the VKline, we will use the production line to produce other innovative nanofiber products.

We continue to work as intensively as circumstances allow, and we will soon have three nice new products for you. We pride ourselves on working with your feedback and thanks to it we will launch a new summer R-shield – Hello summer. The fabric of the neck gaiter is lighter and more breathable, we have implemented a new generation of nose clips in it and the R-shield comes in two sizes– for children and adults. The neck gaiter for adults is broader at neck compared to the original R-shield. Soon there will be also a brand new RespiRaptor respirator, made of nanofiber membrane in an excellent sealing shape. We have also managed to improve the next generation of our window membrane, which may, at the moment, be appreciated by allergy sufferers. As soon as these products are available in our online store, we will inform you.

Will a nanofiber R-shield neck gaiter protect me from the coronavirus?

Nanofiber membrane which is sewed in the area that covers the wearer’s nose and mouth, blocks out 99.9% of all viruses and bacteria (this efficiency level was confirmed by an independent test performed by American institute Nelson Labs). By using these neck gaiters you protect not just yourself but also those around you.

Is personal pickup possible?

We can offer personal pickup in Prague (only), you can choose this option when placing your order.

Who can I contact if I need to order wholesale?

Our business team is available for you on the email address State all your requirements and one of our salespeople will get back to you.

Could you please notify me when a product is in stock?

Yes, of course, but please note that our “Watch dog” which automatically sends emails to customers once a product is restocked is not flawless. Because some products sell out too fast, the service is not able to notify everybody who subscribed to it. Those, who do receive an email, don’t always have enough time to react and make their purchase. If we even temporarily disabled the service, though, the database of all subscribers would be lost. Therefore, we recommend using it mainly to watch products such as ReSpimask.

How many times can I use the VK respirators?

The nanofiber filter mechanically captures the virus (on a similar principle to a sieve), while the copper oxide then deactivates the virus. Deactivated viruses can no longer multiply in the filter and there is no risk of secondary  infection if the mask is reused.

Our VK RespiPro VK respirators can be used repeatedly, with up to 30 hours of protection in total. For example, if you wear the facemask for 5-6 hours a day, one will last you for a week. Information about the effectivity is available on our our website here.

How should I wear and take care of my R-shield?

If you want your neck gaiter to protect you, put the R-shield on in a safe environment – only then you can expose yourself to a high-risk environment. Once you have put it on, try to avoid touching your face or the neck gaiter. If you need to drink, eat or adjust your R-shield, disinfect your hands first – best with an antibacterial gel with alcohol. If you need to take the neck gaiter off in a high-risk environment, do not take it off completely – do not pull it over your head but keep it around your neck and ready to use. After you return from the high-risk environment, take your R-shield off in the following way: roll up the lower part of the R-shield under your chin and then pull it carefully over your head without creasing the fabric with the nanofiber membrane in front of your mouth and nose.

Wash the R-shield in a washing machine on 30 °C – at best separately on a hand washing program. The amount of water is the important factor – it will wash away potential residues of viruses. Then leave the neck gaiter to dry out properly for 12 to 24 hours. Disinfecting, sterilizing or ironing can damage the R-shield’s protective membrane. Use good judgment and wash the neck gaiter every day in case of exposing yourself to a high-risk environment.

Is it even possible to meet the current demand?

It is not in the powers of any commercial subject to boost their supply enough to correspond to the current demand “overnight”. We are doing our best to offer the protection that you require with the highest quality and in sufficient amounts in the shortest time possible. Under current circumstances it is not always possible to provide you with the exact dates and more details. The situation is constantly changing. Therefore, we ask you to be patient and tolerant. Thank you.

Is it possible to sterilize the nanofiber filter with ozone or UV light?

According to CTU’s Faculty of Nuclear Sciences and Physical Engineering a standard face mask can be subject to UV light treatment for 3 minutes from each side. Ultraviolet light (mainly UVC) kills bacteria and viruses, however, it is only active on the surface and a sterilization dose for the new type of coronavirus is not yet known. Also, be careful not to expose your skin to UV light for too long as there is a risk of burns and other health complications. All UV light sources should come with a manual that explains the products’ intended use and possible risks.

Ozone is an effective disinfectant, but it is more effective for water or room treatment than for items (face masks/respirators). It is necessary to lock up the machine generated ozone in the room and let it sit there, so that it can do its job. Usually, 30 minutes are recommended, then the room must be well aired before you can enter.

For reasons mentioned above, we do not recommend sterilizing our products by either method.
