These 0.2 Micron Air Filters will filter out microbes and bacteria.
They can be used in many different ways. They can be used with our wort aerator pumps so you can aerate your wort, or can be used as an airlock in the top of your fermenter. They can also be used to filter air going back into a cask when dispensing real ale.
This filter is not suitable for liquids and should be discarded if it gets wet.
