WHAT IS ANGSTROM SILVER, how Serus self cleaning inline water filters apply angstrom silver to our water filter cartriges.

Our filter cartridges are covered in Angstrom silver particules for antibacterial disinfection and medical advantages.

With the development of nanotechnology, scientists all over the world began talking about the return of the Silver Age to water filtration, medical practice and cosmetology.
Advanced nanotechnology developments neutralized the barrier of high cost of silver in a nanoscale condition and made it available for widespread use.

Russian scientists have developed an advanced technology for obtaining silver nanoparticles, whose diameter is tens of thousands of times smaller than the thickness of a human hair. At the same time, the effective contact surface is tens and hundreds of thousands of times greater than the contact surface of an integral substance of the same mass.
The colloidal solution of silver nanoparticles is a two-component colloidal solution, which consists of silver nanoparticles and water of the highest degree of purification. 100 ml. a colloidal solution of silver nanoparticles contains more than a trillion (1012) active silver nanoballs with a diameter of 1-20 nanometers (1 nm = 10-9 meters). Silver nanoballs are commensurate with water molecules and due to their physico-chemical properties are in suspension, do not precipitate, and the solution remains transparent. The effective area of antibacterial action of only one gram of silver split to nanoparticles can reach several hundred square meters and, under certain conditions, maintain the "bacterial purity" of its territory for many years. Nanoparticles in the nanofiber shell
are perceived by the cells of the human body as a natural biocompatible component.
The unique properties of our silver nanoparticle solution can be used:
• In medicine as a natural alternative to chemical antibiotics;
• In cosmetology as therapeutic and prophylactic additives to cosmetic products;
• In the space industry to disinfect water and grow plants;
• In the cloning industry for antibacterial cleaning of residential buildings, offices, cars, swimming pools, saunas, etc .;
• In the environment for disinfection and cleaning of air and other pollution; • In many other industries.

It is the colloidal solution of silver nanoparticles that is considered as the only real alternative to toxic chemical analogues (antibiotics and disinfectants), which have now been widely used.

• The presented silver solution has the following parameters:
• The concentration of silver in the hydrosol is 50 mg / l 2. The purity of silver is 99.99
• The particle size distribution function has a maximum - 15 nm 4. Absorption spectrum (max) - 395 nm
• The half-width of the absorption spectrum is 40-50 nm

The conducted studies showed high antibacterial and antifungal activity in the studied drug. The activity of silver nanoparticles on gram-negative bacteria was complete (100%). At 40-minute and 2-hour exposures of bacterial suspensions of these microorganisms at all concentrations of silver (worked with undiluted nanohydrosol and dilutions 1/100 and 1/1000) Also 100% suppression of growth and vital activity of gram-negative bacteria was observed.
In relation to Gram-positive bacteria, even with respect to Staphylococcus aureus, there was a 100% suppression of the growth of the bacterial population.
Under the influence of nanohydrosol on Gram-positive bacteria, at 40 minute and 2 hour exposures for all concentrations of bacterial suspension, one result is -100% suppression of the entire bacterial population.
In the study of antifungal (antifungal activity), a clear inhibition of fungal growth was recorded at a 40-minute and 2-hour exposure. The decrease in the fungal population was registered more than 1 million times, the residual population was 0.00083-0.00099%. For fungi Candida glabrata at 40-minute and 2-hour, a 100% suppression of the fungal population was obtained.
