No complaints..does what its supposed to do

Put this on my line for oxygenating my wort as the red oxygen cans aren’t technically good grade

Don’t try jet one day

Does what it says just keep it dry

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 CellarsENUMCLAW, Wa.

A peace of mind item. Keeping the strange out of my cultures.

Works great for aerating wort with an O2 cylinder. No issues after about 4 or 5 uses.

Very useful with the orange cap for no fuss racking. #brulosopher

I keep a few around to use on the stainless steel racking cane.

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.

make sure that you mark with a sharpie the side that faces the pump so that you hook this up in the right direction each time. My understanding is to keep this as a sanitary filter, you have to push air the same direction each time. Also..this filter will find any moisture in your hoses so make sure they are dry before you hook up. Great filter easy to use, but make sure you have the right size hose if you are going to use this with the Whisper aquarium pump.

This is great to add to a two port carboy cap and create a sanitary siphon. Place a racking cane in one port and this in the other. Blow through the sanitary filter and the racking cane will start siphoning. I saw the in a BYO magazine the other day and it works great. I like it better than the auto siphon because all you have to do clean the cane, not the whole auto siphon.

Simple, effective, peace of mind knowing my oxygen system is protected from any possible contamination.

It just works, nothing fancy

Easiest thing to help clean the o2 and or Co2 before aeration. It is such a simple peace but a must have not to mention, It's Cheap!

I always keep it clean and store in a plastic bag.

I use this as an adapter for both my O2 wand for oxygenation and for CO2 for sterile/closed transfer with my Better Bottles at very low pressures. Works well and easy to use.

I use it for my siphon when I am racking. Works really well. DO NOT GET IT WET or it is game over. I keep a back up incase I have an accident.

The filter works fine. I had a problem because the tubing required for the filter is larger than the tubing for most aquarium air pumps, including mine. Even with soaking the hose in hot water, I can barely fit the tubing onto the filter. This is a problem every time the tubing between the filter and stainless air stone is removed for cleaning. There are better designed filters that accommodate both smaller and larger air hose.

You have to have this. I don't trust my pure o2 to be so pure from the tanks . So this is hooked up to make sure no nasties are getting in my wort.. Like the instructions say don't get it wet. I keep mine all wrapped up in a bag inline with my o2 line. Just to be safe. Wish they had other size connectors ... But it works for my setup.

I've purchased several of these filters for my oxygenation system post the Blichmann Therminator. I hook this up inline from my air compressor to my oxygen stone and then to the cooler.

You need one of these if you're going to oxygenate. These are pretty sturdy, the only thing is to take care not to get them wet. Fortunately it will be very obvious if you've messed up... inspect your filter every time you use it and you'll usually see tell-tale black spots on the filter if you've infected your filter with some unwanted organism.

Manditory for oxygen injection.

I sue this with my aquarium pump to aerate my wort and I've never had a problem with contamination. Using this really helps me to get a quick kick-off on my yeast a great attenuation.

I use this in line with my oxygen stone. For the price, why wouldn't you add in a layer of protection?

I use this in line on my aeration system works good.

I'm using this in-line for my O2 aeration and working great! Really simple to install and use...

I've never truly worn one out, just simply replace from time to time. Never had an infection problem as a result!

I use this when racking my beer. I use the orange carboy cap with a stainless racking cane in the middle slot and this in the other. I start the siphon with CO2 through the filter and I presume the ambient air passing through thereafter is cleaner than without. Important if you're going to rinse and store the yeast cake

We all know that one of the top reasons for funky beer can be lack of cleanliness. Using this filter I can feel good about the oxygen I'm pumping into my wort.

I use this to aerate both my starters and wort. I've never had an infected batch from this product

I use this filter for oxygenation as well as doing a sterile transfer using a carboy hood and a racking cane. I've never had and issue.

This was a decent product though I haven't used it much. I found a sterilized foil piece over the flask for a yeast starter to be sufficient.

This is a very handy tool to have on hand. Make sure to mark what the dirty side is.
