Getting a siphon started can be one of the biggest hassles that homebrewers face. There are endless methods you can try that usually end in a siphoning disaster. If this sounds familiar you will LOVE this Sterile Siphon Starter! No sucking the end of the tube, no plungers with faulty gaskets, no shaking, no filling up the tube with unsterilized water, nothing to break, no contamination, no disturbing the sediment, and no fuss!
Simply blow into the sterile filter, which slightly pressurizes the carboy, forcing beer to flow up the racking cane and out the tubing, thus starting your siphon. This is hands down superior to the numerous other methods of starting a siphon (and we have tried them all!)
This size will also work for larger-mouthed plastic carboys!
How to Use: Attach the Sterile Siphon starter assembly by firmly pushing the carboy hood over the mouth of the carboy. Slide the stainless racking cane to the desired depth, just about the sediment level and blow into the white, sanitary air filter for 2-3 seconds until you have a solid flow of beer running out the tubing. There is no need to worry about contamination from your mouth, as the sanitary filter removes 99.98% of airborne bacteria.

26 inch Stainless Racking Cane
Red Sediment Reduction Tip
Rubber Carboy Blowoff Hood w/White Caps (3, 5, 6, 6.5 Gallon smooth neck)
5′ of 3/8″ ID Vinyl Tubing

Sterile Air Filter
About the White Sterile Filter: 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.
I have this and it works really well. You blow into the sterile filter to start a siphon. The air that’s drawn in through the filter during siphoning is sterile. You can siphon beer or cleaning/sanitizing solution. If you siphon sanitizer, you’re left with a sanitized carboy and filtered air.
