Get help | My filter is discoloured inside - is it a problem?

<Get Help>

Discolouration both on the filter refill and in the casing is perfectly normal.

In Malta we experience rust in our pipes both in the building we live in and from the main supply.

The rust is filtered out, but will cause discolouration inside the filter and on the wrapper of the refill cartridge. Here is an example of what is normal, kindly sent in by a customer.

You can wash the casing that holds the filter in gentle soap and warm water.
