A great filtering kit for homebrewers. Use 2 corny kegs (not included) to push your beer/wine through at low psi (under 5 ideally. This will come with a 2-pack of rough filters. Each filtering session you will need 2 filters (1 per side). This comes with flare fittings on the QD's so you can easily switch out to Pinlock or even commercial kegs (with adapters).
