Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://modelbuildlab.com/how-we-research#our-score Water in the airline is one of the most maddening faults in airbrushing because it strikes without warning. Everything sprays perfectly until a drop of condensed moisture blasts through the nozzle and craters a nearly finished coat. Compressing air concentrates its humidity, and as that air cools in the hose the water falls out of suspension. A moisture trap catches it before it reaches your paint. Most compressors ship with a basic trap on the regulator, but in humid climates or during long sessions a second inline filter near the brush adds real protection. This guide compares compressor-mounted traps, small inline filters, and pistol-grip designs, and explains where in the airline each one does its best work. ## Picks ### 1.
