This versatile little filter is a beer maker's insurance policy! Whether you’re aerating or racking you will appreciate having the peace-of-mind of knowing that your brew will not be contaminated by whatever is floating around in the air. Use it anywhere you need to keep something sanitary. Both 1/4"" and 3/8"" tubing will attach to it, 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 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. It is not appropriate for long term storage of beer as it is not an oxygen barrier.
  • Inline Aeration/Oxygenation Filter: With an oxygenation or aeration system, such as our FE375 or FE380, it will filter contaminants out of oxygen or air. It is connected inline between pump/O2 tank and Stainless Diffusion Stone.
  • Hand Pumps: Some breweries use this filter with the breweries hand pump system. Air going back into the cask is sanitized through this filter. This has extended shelf life of Real Ales by up to 2 weeks!
  • CO2 Filtration: Used inline with your CO2 Kegging setup, this piece can be used to filter out any potential contaminants from your CO2 Tank.
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 airflow going one direction when using it. The filter should never get wet, so don't try and sanitize it by dunking it in sanitizer. If you want to clean the outside of it, use Alpet D2. To store the filter, use a little tinfoil on the "In" of the filter and store in a zip-lock bag. Can last up to 1 year. Discard if there are any signs of discoloration.
This product qualifies as a HEPA filter under US government standards.

What is the maximum safe pressure for this filter? Using it for CO2/N2 draft air filtration.
Michael Boehm on Feb 19, 2018
BEST ANSWER: This product has a maximum functional pressure resistance of 35.9 millibar or roughly .5 psi
Dose anyone know how many uses/how often this needs replaced when only used to start siphons?
fletcher little on Jan 24, 2018
BEST ANSWER: This filter can last up to one year and should be discarded if there are any signs of discoloration. It is important to never get the filter wet and to store it dry at all times.

Sanitary filter
Haven’t used it yet, am installing air dryer first. Looks to be a good value, and some extra insurance around the winery that our air driven, double diaphragm pumps aren’t exhausting microbes around the tank and filling room. Jeff W, Babick Cellars

I am using this to create a simple. sanitary siphon with a two-port carboy hood and a racking cane. This system greatly simplifies my setup and cleaning when racking to a secondary fermentor or bottling bucket. There are lots of other uses for this handy little filter as well.
