Protective half mask is designed to meet all the requirements for paramedics, firefighters, police officers, it is intended for all users who are so-called “in the first line”.
The P3 R particulate combined filter allows the maximum degree of protection to be achieved, which corresponds to the FFP3 characteristic.
Half masks can be ordered via e-mail or telephone.

Advantages over respirators and masks
The P3 R combined particle filter offers a maximum level of protection that corresponds to the FFP3 characteristics. The product is intended for all users in the so called “font line”, such as doctors, nurses, paramedics, firefighters, police and military personnel, customs officials as well as shop assistants, line workers and similar.
The protective mask is designed to significantly reduce the financial costs of all organizations that make use of these types of resources.
The mask set is completely designed and manufactured in the Czech Republic, this means it is not subject to the risks involved in the importation of materials from abroad and its manufacture supports the local economy.
Disinfection and sterilization
The half mask is disinfected in ethanol, sterilization is done in an autoclave at 121°C and a pressure of 2 bars for 20 minutes. Disinfection of the filter is possible using standard chemicals (e.g.: disinfection based on Peracetic acid), sterilization is done by plugging up the filter and subjecting it to 75°C. Sterilization allows you to repeat up to 12 times.
Comparing the purchase cost of the RP95-M half mask with regular respirators
Our product, the RP95-M half mask (at FFP3 quality), brings
substantial financial savings in the first week of deployment in
comparison with other half masks as well as disposable filters with
the same protection level. The costs are on average 8 times lower
in one month of usage than disposable respirators with the same
protection level (FFP3).
Our solution allows a far greater number of personnel to be
equipped with quality protective tools and secures their protection
for longer periods with a high standard of quality and comfort.
Q: The mask is similar to the one developed a few weeks ago at the CTU, the one modified for manufacture by 3D printing by the Czech Institute of Informatics, Robotics, and Cybernetics (CIIRC) to be precise. How is this possible?
A: The RP95-M half mask is based on the CIIRC RP95-3D model. Based on the CTU’s start-up company TRIX Connections exclusive license, the design of the mask was modified by our technologists and designers for mass production.
Q: The mask seems large; won’t weight be a problem?
A: The weight of the half mask is 160g including the filter. During testing it was proven than the mask can be comfortably work for long durations of time.
Q: Why is the filter fixed to one side?
A: The filter is mounted to the side due to safety reason during use. When lifting an object off the ground and tilting one’s head, there was a risk that the mask would be pushed off by one’s own chest. This solution also widens the user’s field of view.
Q: How many times can the mask be used?
A: Thanks to the durable materials, the mask can be sterilized in and autoclave multiple times. The polyamide used on the mask allows for a limitless amount of sterilizations. The sealing material, a thermoplastic elastomer, allows for a 100 sterilization cycles and an unlimited amount of disinfection cycles.
Q: How many cycles does the filter last?
A: The limiting factor on the life of the filter is the degree of mechanical fouling due to heavier breathing. In a dusty environment such as a building site, the filter can be clogged in two days. In a clean environment such a hospital, the filter may last at least a week of continuous usage. In practice, this time may prove longer. Clogging up does not influence the filter’s ability against viruses, however.
Q: Is the use of the respirator dangerous to the user’s surroundings?
A: Using the half mask primarily protects the user. If the user’s surroundings are not protected otherwise, it is good to supplement the respirator with a basic surgical mask. Our team is currently working on incorporating a nano particle fabric into the exhaust valve that would eliminate the need for a supplementary surgical mask. Masks thus equipped would be ideal for old age homes and maternity wards.
The original prototype of the half mask for manufacturing by 3D printing developed at the CTU in Prague, the Czech Institute of Informatics, Robotics, and Cybernetics (CIIRC) to be precise. TRIX Connections s.r.o. (a CTU start-up) prepared a modified model of the RP95-M for injection molding on the grounds an exclusive license. R&D personnel at CARDAM s.r.o. and BENEŠ a LÁT a.s. took part in the design and development for mass production. The Institute for Physics at the Czech Academy of Sciences developed the testing apparatus for the quality control prior to shipping. JAN SVOBODA s.r.o partook in the manufacturing and delivery of the production tools. To ensure speeding up the manufacture of the molds and production launch, work was distributed among 6 different tool works companies that are working on 10 molds in parallel to ensure a production capacity of 50 000 masks weekly. In the case of a high demand for this product a simple modular increase of production in production is easily possible.
