Des-Case disposable breathers retain particulate as small as 0.5-micron (73.5% efficiency) or 3-micron absolute, are rated for 20 cfm (600 L/mn) and feature a 1" standpipe.
The unit should be sized by looking at system height restrictions and the amount of water adsorption desired.
Remember that you should not always fit the smallest unit for economy of purchase price.
When comparing the three common sizes DC-2, DC-3 and DC-4, the price variation is approximately 30% from the least expensive to the most expensive. However, the DC-4 unit has twice the drying ability of the DC-2, and the DC-3 unit has one-and-a-half times the drying capacity of the DC-2.
