In Line Air Filter

An inline sanitary filter that filters down to .027 micron with a 99.99% efficiency. Use it anywhere you need to keep something sanitary. Both 1/4" and 3/8" tubing will attach and it will snugly fit in any standard stopper as well.

Check out this list of suggested uses:
Airlock: The most common use might be as an airlock on any kind of fermenter. Unlike other small sanitary filters, this unit fits perfectly into a stopper. Works great for conical fermenters, where displacement air is taken in when samples are taken or trub is dumped. Using the sanitary filter as airlock also eliminates the concern of drawing air back in as hot liquid cools and contracts in a fermenter. Not appropriate for long term storage of beer or wine as it is not an oxygen barrier.

Inline Aeration/Oxygenation Filter: With an oxygenation or aeration system it will filter contaminants out of oxygen or air. It is connected inline between pump/O2 tank and diffusion stone.

CO2 Filtration: Used inline with your CO2 Kegging setup, this piece can be used to filter out any potential contaminants from your CO2 Tank.

Storage: Store in Ziplock bag in a dry place with minimal moisture exposure. Can last up to 1 year. Discard if there are any signs of discoloration.

About the inline filters: There are two sides to the filter - an "in" and an "out". The direction you use doesn't matter, however, you want to take note of which way you first push air through it and always keep it that way. There is an arrow on the edge of the filter housing that we use to keep the air flow going one direction when using it. The filter should never get wet, so don't try and sanitize it by dunking it in sanitizer. To store the filter, use a little tinfoil on the "In" of the filter and store in a zip-lock bag.

STORE DRY AT ALL TIMES. DO NOT SANITIZE FILTER.
