Instead of diffusing pure oxygen into your wort this system uses filtered air. The included air-pump pushes air through an inline sanitary filter which is then dispersed into the wort through our two micron threaded stainless steel diffusion stone. The advantage of an aeration system is that you never have to buy replacement oxygen tanks. The down side is that aeration takes longer than oxygenation. Because the atmosphere is only about 20% oxygen, the diffusion stone must be left running in the wort for approximately 30–120 minutes (however even 5 minutes of aeration is better than shaking the carboy.) There is no concern of contamination during this period, however you do have to monitor the fermenter periodically for possible over foaming. While you are brewing, this system can also be used to pre-fill fermenters with sanitary air. Replacement filters, FIL90, which need replacement every few years, are available for $4.99.

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. If you want to clean the outside of it, use Alpet D2 (CL60). To store the filter, use a little tinfoil on the "In" of the filter and store in a zip-lock bag.

Waste of money
This item is worthless in my opinion. The hose from the pump to the filter is so loose it couldn't get air through the sanitary filter if it wanted. After the stone gets wet in the wort, it takes more pressure to release bubbles. I ended up buying the Oxygen bottle regulator and taking the hose assembly and using it with the regulator as told to by one of the people there.
Hmmm. I thought that I was finished with tropical fish... anyone need a pump?

Great system for the $
I've been using this for over a year now and it has really increased my attenuation. Love it.

Improves Fermentation
I've been using this product for about 2 months with spectacular results. Now I can get fairly good attenuation down to 1.005 for my dry Kolsch brews, even at lower ferm temps. I typically run let the pump run in a bucket of Star San for about 5 minutes to sanitize the stone, bubble off the foam, and then aerate for about 30 minutes in the wort.

This is a simple product, but works great. Really glad I made this purchase

Great system
Easy to sanitize-I used Star San. One the wort was in the fermenter, I dropped the stone in and let it go for 15 minutes. Just plugged it in and dropped in the stone for 15 minutes, which was a recommendation I heard on Brew Strong.

Works great!
Purchased almost 2 years ago and still works great. I have used in small and large batches with great results. highly recommended.

Great inexpensive system.
An O2 bottle would go quicker, but also cost more. This is great for being inexpensive and works great and don't have to worry about filling an O2 bottle.

Must Have!!!
I, like the others, will never brew with out this device again or at least with out oxygen in the wort on every beer I brew. Its easy to use and pretty easy to clean. It has helped out the fermentation of my beers 100%. I just throw it in the fermenter for 15 min. with the wort, then add the yeast to the wort and let the pump aerate with the yeast for another 30-90 minutes, depending on the OG size of the beer.
