In-Line Sanitary Filter for Aeration Systems
Filters down to .22 micron with 99.99% efficiency. Use with 3/8" ID tubing (1/4" ID will also work). Can be used as a microbiological air filter for aeration systems, or keg hand pumps. This filter can also make sterile water for yeast starters, rehydrating dry yeast, or topping up.
This filter works great for my aeration stone and pump.
Bought this a couple months ago, made all the adaptations to it and even went as far as buying tubing that would fit it. Long story short after assembling my set up with pump and everything it barely puts out a fizz from the wand. When you see demonstrations of this product using pure oxygen bottle it's not even close. I have yet to try the bottle method but disappointed I wasted my money and then some on this.
The short and sweet answer is need a reducer to adapt the filter to the smaller tubing coming out of most air pumps. Also if you are using the bubbler with wand ( which is great) than another reducer is required. Haven't purchased reducersyet but believe the filter will work great when I do.
I've had no issues with contamination. The only difficulty I had was getting the tube onto it but once I heated up the tube slightly I was able to wiggle it on.
I ordered this to put inline between my aquarium air pump with 1/4" barbs and the stainless airstone / wand I also purchased. The barbs on this are much larger than 1/4". The only way I could use this is if I get some couplers and larger tubing to go to the larger size for this and back to the smaller size for the wand.
