Do I need to filter the mobile phases?

Mobile phases should be filtrated if necessary. They can be filtered through a 0.45 µm filter. This removes any particulate matter that may cause blockages. Filtering HPLC solvents will benefit both your chromatography and HPLC system. Pump plungers, seals and check valves will perform better, and lifetimes will be maximized.
