i3 sterile filters have a usage life of 50 days. They can be used safely and without limitations for this length of time. The bacterial retention, the bacteriostatic action of the filter surface and an adequate flow rate are ensured throughout the filter's usage life.
As well as the capacity of the filter, the efficacy of the bacteriostatic filter surface is a major factor limiting the length of time for which sterile filters can be used; the bacteriostatic surface offers protection against retrograde contamination. Extensive testing and clinical investigation have shown that the bacteriostatic efficacy of the high-performance plastic materials begins to drop after more than 50 days of use and thus indicate that these filters should not be used for longer periods.
When i3 sterile filters are used for longer than the specified 50 days, i3 Membrane GmbH does not guarantee the function and efficacy of the products.
The filters have a validated storage life of 5 years. The expiry date is marked on the product packaging and labelled with an egg-timer symbol.
i3 filters for medical sterile filtration are single-use products. They can be discarded with household trash after they have been used. When removing the filter, follow the instruction manuals.
Yes, i3 point-of-use sterile filters with the intended purpose of infection prevention are CE-marked Class I medical devices. As a manufacturer of medical devices, i3 Membrane GmbH has a quality management system that is certified in accordance with DIN EN ISO 13485 and thus complies with the demanding requirements relating to the safety and reliability of its products and services and the minimization of the risks of its products.
The i3 ONE and i3 TWO connect point-of-use filters are attached to the water faucet or the shower hose using a quick-release fastening. The i3 TWO direct has a standard screw thread that allows it to be attached directly to the shower hose. The exact procedures for installation and removal are described in the following instruction manuals: i3 ONE Instruction manual, i3 TWO connect instruction manual, i3 TWO direct instruction manual.
The high-performance flat membranes used in i3 sterile filters are designed so that the flow rate is adequate even with low water quality. However, if very large amounts of particulate matter (e.g. rust, sand etc.) are present in drinking water, the flow rate may be reduced and the usage life may be shortened as a result.
