The Alya water filter is compatible with all refrigerator models. It is installed on the "back" of the refrigerator, meaning externally at the rear. It is simple to connect and does not require a technician, it fits easily. It retains rust, stones, mud, suspended particles, chlorine, and other heavy metals, while simultaneously improving the taste and smell of the water. It can be installed in refrigerators that already have a filter and produce ice or have a water dispenser, as well as in ice makers and coffee machines.
