I'm not exactly sure how much water it should filter out of the air because it's the first air filter/dryer system I've ever used so I don't have a comparison but I do think it should have caught at least 90% of the water in the overhead line. And as you can see there is some moisture in the little filter trap. But when I used air with an air gun for the first time today, he filled the gun with water that ran down my arm. I then turned off the compressor and drained the air compressor tank as more water came out of the drain line. So I'm thinking about giving it 3.5 stars but can't get half a star so it gets 4 stars for now until I can invest in a better and more expensive, better quality dehumidifier system. Oh, and please correct me if I'm wrong about whether it's properly connected. There are no installation instructions.
