The i3 FOUR inline sterile filter offers reliable protection against contamination caused by waterborne pathogens such as Legionella pneumophila, Pseudomonas aeruginosa or mycobacteria. It is installed to ensure the sterile filtration of tap water in the inflow pipes of devices and instruments.

Protection against legionella in dental treatment units

Dental offices must ensure that the dental treatment unit (dentist chair) uses drinking water which is free of microorganism and microbiologically safe for patients and users. Especially when it comes to older treatment units, this requirement can only be satisfied by the frequent use of chemicals for cleaning and disinfecting the water supply within the unit. To ensure these chemicals are effective, it is possibly necessary to filter contaminated water before it enters the treatment unit. The interplay between the sterile filtration and the suitable chemicals guarantees a microbiologically safe use of dental treatment units. The i3 bacteria filter is installed within the water supply, behind the angle valve and before the treatment unit.

• The i3 FOUR has an application period of 50 days
• The water filter provides lasting protection against waterborne pathogens for immunocompromised and immunosuppressed patients
• 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.
• Clear product identification for a legally conform documentation of the filter change using the i3 trackApp or i3 change service
• The LRV (log reduction value) for the bacterium Brevundimonas diminuta is > 7 log/cm²
