I have recently made some home pressed olive oil but it is quite cloudy and I wanted to filter it so it will keep longer and be a bit more pleasing to the palate and the eye. I initially used a muslin (ham) bag in a steel colander over another steel bowl and weighted down with 70kg of gym weights to press. I was wondering if it is effective to try running it through paper coffee filters to get rid of the fine particles?

The raw oil can be filtered by through a coffee filter or fine mesh strainer to remove particulate matter. Filtered oil is less likely to burn during cooking.

The oil is not ready to use after pressing. It needs to be cleaned and filtered. This requires only buckets, water, a funnel and coffee filters.
