From HBF: Make sure the components you use are compatible and rated for your intended application.  Contact manufacturer with questions about suitability or a specific application.  Always read and follow manufacturer directions.

 

Note from HBF: These type of filters are sometimes used as part of oxygenation or aeration setups.  I’ve also used a similar filter to help start a siphon.  See MoreBeer’s Sterile Siphon Starter for more info on that process.  The basic idea is you use a compatible carboy hood and racking cane and blow into a compatible filter to start the flow of liquid.  The filter used in MoreBeer’s setup looks similar to this one, although I’m not certain it’s identical.
