DGD-5005-20 Micron Question

[wtrinfo]

What is the micron rating of the DGD-5005-20? I'm confused because some places it says 50 and some it says 5.

The Pentek DGD-5005-20 water filter is a dual gradient density filter. There are two different densities within one filter. The first stage of the Pentek DGD-5005-20 provides 50 micron filtration. The second stage of the Pentek DGD-5005-20 provides 5 micron filtration. With the DGD Series filters you get two micron ratings for each filter.
