Again, not true. A Mako 1801 contains just carbon. The 1803 contains carbon, hopcalite, and other goodies. Same filter, different function. Both are breathing air filters, but one is significantly less expensive. They fit in each other’s filter housings also, so it’s easy to get the wrong filter.Anybody that is running a compressor without a filter that converts CO to CO2 is not running a scuba compressor. Paintball, PCP air rifle yes, but not scuba. Some may say the exception would be an oilless compressor but even then if you get CO from another source you want to remove it.
Which would be a rumor.Even "professional dive shops" sometimes get it wrong. I recently heard a rumour about bad tank fills that were blamed on an idling diesel delivery truck in the alley behind the shop.

Diesel engine dont produce CO, and any particulates are going to get removed by any competent condensers and filter.
Their last analysis says nothing about the CO in their intake today.Yes. They should have their last analysis report available for customers. Ask for it if it isn't posted. Do they use inline CO detectors? Do you test your tanks for CO and oxygen content?
The other way is lawyers. I know someone who get poisoned on a dive. The tank analysis showed all sorts of nasty volatile organics and it turned out to be because the dive shop was repainting their tanks near the air intake, and apparently those kind of volatile organics passed through whatever filters they were using. "They aren't in business anymore" was said with evident satisfaction.
DAN will send you a free sampling kit if you think you got a bad fill. In most cases of scuba accidents it's on the list of things they check.
Looks like I opened a can of worms
We’re arguing the same point. Except you’re saying that it isn’t a scuba compressor (or a grade E compressor) if the correct filter isn’t installed. I think you can make grade E air in most situations with the wrong filter installed, but in some situations, (runs too hot, truck idling nearby) the hopcalite can save your bacon. But I know a lot of folks who run with the wrong filter and never fail an air test. They never perform one either.If they do not contain hopcalite they should not be called scuba compressors.
Ummm? from your own abstract....Are you sure about that? Pretty sure any internal combustion engine can produce CO if not functioning properly.
