The Pre-Screen Filter can be attached to the intake hose of the newer Mini Jet Model MJT93089-3 to screen out large particles of sediment such as oak chips and/or seeds before they reach the pump. This should prolong the life of the Check Valve and allow you to maintain a much cleaner pump. Highly recommended if you ferment with oak chips, elderberries, grape skins or if you want to use the pump to rack your wine.

The Pre-Screen filter will not allow any large solids to get inside the pump and cause damage – Buon Vino highly recommends this be purchased with the Mini Jet Filter.
