Sterile filters by i3 Membrane have a lifespan of 50 days. Within this period, they can be used safely and without limitations. Bacterial retention, the bacteriostatic action of the filter surface and an adequate flow rate are ensured throughout the filters' usage life.
In addition to the capacity of the filter, the efficacy of the bacteriostatic filter surface, which protects against a retrograde contamination, is a factor limiting the length of time for which sterile filters can be used. Extensive testing and clinical investigations have shown that the bacteriostatic efficacy of the high-performance plastic materials begins to drop after more than 50 days of use. This is why i3 Membrane's sterile filters should not be used for longer than 50 days.
When i3 Membrane's sterile filters are used for longer than the specified 50 days, we do not guarantee the function and efficacy of our products.
The filters have a validated shelf or storage life of 5 years. The expiry date is marked on the product packaging and labeled with an hour-glass symbol.
i3's filters for medical sterile filtration are single-use products. They can be discarded with the household trash after they have been used. When removing the filter, follow the instruction manual.
Yes, i3's point-of-use sterile filters intended as infection prevention are CE-marked Class I medical devices. What's more, as a manufacturer of medical devices, we have a quality management system that is certified in accordance with DIN EN ISO 13485 and thus complies with the standard's demanding requirements relating to the safety and reliability of its products and services, as well as the minimization of the risks of our 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. i3 TWO direct has a standard screw thread that allows it to be attached directly to the shower hose. Please see the following instruction manuals for the exact installation and removal procedures: i3 ONE instruction manual, i3 TWO connect instruction manual, i3 TWO direct instruction manual.
The high-performance flat membranes used in i3's sterile filters are designed so that the flow rate is adequate even when the water quality is low. However, if very large amounts of particulate matter (e.g. rust, sand) are present in the drinking water, the flow rate may be reduced, and the membrane's lifespan may be shortened as a result.
