Not to get too off-topic, but home depot also told me they don't carry propane burners or turkey fryers... A quick walk down to the grill section and they had about 10 different models to choose from... Like someone said above, mass-market stores don't really cater to the DIY-er who might need a point in the right direction when entering a building the size of some towns...

For the price of the regulator and the diffusion stone, you might as well get the 40 dollar kit with everything. The stainless steel wand is very helpful in getting the stone to the bottom of your fermenter instead of having the plastic tubing float around...

Does anyone use a HEPA filter with the O2 tanks since they aren't medical grade? If not have you had any issues with just going straight from the tank to the stone

As far as a HEPA, I dont think so.. They do have sanitary in-line filters you can use to remove any particulate matter / bugs that could be in the gas stream.

Yeah that is what I am talking about and I have an aeration system but I have been using a HEPA filter inline since the O2 isn't medical grade and could easily have contaminants in the bottle. However I think my filter is making it hard for the O2 pressure to be great enough to push anything out of the stone... Should I just scratch the filter out of the equation?

Most guys use atmospheric air. Do you think that is Medical Grade? I have no problems with the Red Cylinders. No filter. Just an in-line stone.

Ok just checking. I wasn't saying it was not right to not use a filter I was just making sure people have had good results without one...

I have the inline filter but for some reason I never used it. So 2+ years of just using the red bottles from HD and no issues.

I don't dispense beer with food grade CO2 either.
Gas is gas.
If the tank has rust inside, it won't infect the beer, but could taste funny.

I don't filter my disposible O2 gas, and never had an issue.
