The white filter on my Symphony™ Vac & Steam, model 1132 is turning blue. Do I need to change it?
Answer: 1. This machine does not require a filter to operate. The machine will either come with a water filter or a "dummy" filter.
2. If a calcium filter is being used, it will change from green to blue, which will usually occur over a period of 6 - 9 month time span depending on use. When the filter is completely blue, it is time to replace it.
3. Using distilled water may extend the life of the filter.
