The ALPS ceramic dome is the first stage of the ALPS filtration process.

The lifetime of the dome is 6 to 9 months.

Before use it is good practice to immerse or soak the dome in water for at least ten minutes. This will rid the dome of any dust particles from the manufacturing process and prime it for use.

Assemble ceramic dome via butterfly nut & washer (supplied with dome) onto the smaller (top) container.

Gently remove and gently clean the dome periodically with a soft toothbrush/fabric under running water, especially if residue forms on the dome surface.

The ALPS ceramic dome filter (0.2 micron) purifies water from rust, dust, sand, silt and bacteria such as cholera, typhoid and coliforms.
