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.

Seemingly good alternative to costly oxygen bottles.

A fellow brewer has one and he really likes it

Cheaper than O2 but better than 10 minutes of stirring.

Trying something new and cost was right.

affordable for a beginer that has never aireated wort

Reading book called "Yeast" looking to put 8ppm in my beer without shaking anything.

Plug and play easy
I wasn’t sure about this when I bought it, but now I’m sold! I’m tired of paying for those little O2 bottles at Home Depot. It takes longer to use this, but I’m usually cleaning up anyway. And it requires no attention—plug and play! I’ve used it on 3 beers now and note no difference between an hour of this and a minute of O2.

Worked very well even with a 1 bbl unitank.
Made a vigurous fermentation.

Good value
I've used this aeration kit for two batches so far, and it definitely increases the fermentation activity. I did have some foaming issues, but that's to be expected.

Awesome bang for your buck!
Woah! Never had a more active fermentation. I've always just done the manual aeration (shaking the shit out of the fermenter) and thought it worked pretty well, but I put this guy in there on a Belgian Tripel for 45 mins and set it in my fermentation fridge. Came back in less than 12 hours and the thing was cranking like I've never seen it. Totally worth the money and I'm excited to check the ABV at the end to see how efficient my yeast was. Kind of a great first step into proper aeration.

Well, I don't know if it really does anything for my yeast but it definitely foamed up my beer.

Air it out
If you can't afford an oxygen tank, get this. Much better than shaking a heavy carboy. Plug it in, and let it bubble for 30 mins or so. Complete and ready to go.

Oxygenating Wort
This pump is easy to use and easy to clean. Dropped in in the fermentor and let it run. Foam reached the top in twenty minutes, but as it was only a small batch (2.5) it seemed to be just fine. While I can't actually measure the O2 ppm, I got a very robust fermentation after a about a 12 hour lag. Looking forward to a great beer.

Not convinced it’s worth the trouble
Difficult to get the bubbler to stay on the bottom of the carboy. Finally used a long meat fork to hold it down. I don’t notice any difference after using it. In fact, time to yeast activity was increased. Coincidence? Possible.

Response from MoreFlavor
Hello Jeannie - When oxygen is introduced and forced into a fermentation schedule, yeast will indeed have an increased time in their aerobic respiration stage. There is more oxygen in the medium to consume, this will also depend on pitching rates. Oxygen gives yeast a stronger cell wall, making them more adapt and stronger for high gravity fermentations.

Worked like a charm
Decided to up my game and start aerating my brew. This little pump, filter, and stone worked well. Easy to use and clean too.
