i3 FOURSterile filter
The point-of-use i3 FOUR sterile filter is used on cleaning nozzles for rinsing medical products (e.g. endoscopes) and serves towards sterile filtration of tap water. It protects immunodeficient or immunocompromised patients receiving medical treatment in oncology, transplant and intensive care units as well as neonates from infections caused by waterborne germs. It serves to prevent infections caused by bacteria such as legionella pneumophila, Pseudomonas aeruginosa or mycobacteria.
- The i3 FOUR complies with the fundamental characteristics of a medical product and is validated for an application period of up to 50 days (7 weeks). Connection is via a quick-release adapter (3/8")
- The filter housing material contains a bacteriostatic additive and reduces the germ count for retrograde contamination by 4 Log levels within 24 hours (as per the standard¹)
- The i3 PES membrane used in the i3 FOUR has a nominal pore width of 0.2 µm and corresponds with the definition of sterile filtration²
- The i3 PES ensures great stability and a consistently high flow rate by reducing deposits of substances in water (adsorption).
