The EZ filter is specifically designed to be used to filter the alcohol produced by a 25ltr still (where legal) or up to 300ltrs of water.
Alcohol should be diluted to below 50%ABV before passing through the filter. Whilst a complete EZ filter system is available which uses two 10ltr buckets, one as a reservoir and one as a collector, it is fairly easy to use a single bucket fitted with a tap and connected to the filter via an appropriate piece of tubing.
For best performance, the Carbon blocks on the filter should be changed after each run through. The washers should be changed when they become compressed.
