I am very glad that you get top quality air where you live. Unfortunately, that is more the exception than the rule.

I have been part of the diving industry since 1981 and air systems were what got me into it so I have seen just about everything you can see in a dive shop.

I make my living selling compressors and especially oil and filters and only a few shops actually pay as much attention to their system as they should. Of the 500 or so dive shops that I have contacted over the years and "sampled" their air, I personally would not dive with about 3/4 of them.

Don't get me wrong ... I am not attacking all the dive shops. I have several customers that have outstanding systems ... both air and nitrox. But there are a lot of them out there that just don't give a damn about their air or their compressor until it breaks. That is where the home compressors are selling.
