Quality stainless steel filter makes filtering/aerating your wort easy! Wire arms expand to center the filter over your fermentor. The first stage of the filter is coarse and removes larger particles (loose grains, leaf hops, large spices, etc) while the second rounded filter is finer and removes smaller particles (some pellet hops, smaller spices, etc). The first stage of the filter is removable and makes for easy cleaning/sanitizing.
*Notice* All of the units we received from the manufacturer appear to have some cosmetic flaws in the stainless finish inside between the two filters. It shouldn't affect the performance or life of the product, we want you to be informed, however.
