The Vizard-M respirator not only stops the entry of pathogens into the respiratory tract, but also actively kills them.
The principle of bioactive protection of Vizard-M
A virus or bacteria settling along with large aerosols on the surface of a BDC-Air Cu35 primary filter (copper), as well as some viruses settling along with smaller aerosols passing through BDC-Air Cu35 material, meet with BDC-Air Bio material and are destroyed.
Bacteria exhaled by humans do not multiply on the inner surface of the mask, because a BDC-Air Cu35 primary filter is installed which prevents the growth of bacterial colonies.
Key problems of other respirators and masks
- All masks and respirators (industrial, medical, N95, etc.) only prevent various particles from passing through them (dust, aerosols with bacteria or viruses).
- Respiratory pathogens accumulate on the external surfaces of the masks, thereby representing a ticking time bomb, increasing the risk of infection.
- This risk increases with longer use of the mask (> 3 hours) and with a higher frequency of clinical contacts.
- Live pathogens that accumulate on the mask pose the greatest risk of infection.
Description of bioactive filtration technology
Bioactive tissue
An initially developed fabric for the aerospace industry to destroy viruses and bacteria has been adapted for use in respiratory protection against pathogens.
The fabric is made by chemical modification of a polymer fiber with bioactive reagents that create a complex of functional groups on the surface of the fibers that inactivate viruses and bacteria. After inactivation of viruses or bacteria, the active domain zones of the material become inoperative. The number of active functional groups is calculated with a 10-fold reserve for air purification with a content of more than 5000 CFU per 1m3 with continuous moderate use for 40 hours.
The fabric retains its properties even after 60 hours of wear. The effectiveness of the tissue is confirmed by independent laboratories around the world (USA, Canada, Germany, China, Belarus). Tests were conducted for viruses and bacteria.
The fabric has strong antiviral and antibacterial properties, is not toxic when breathing and does not cause an irritating effect.
