Do you wash your carbon filter before first use?

  1. Just got my carbon filter. No instructions in the box. Am I supposed to hose this thing off to get rid of the dust?
  2. No, you want to avoid moisture with carbon filters, it can shorten the lifespan. I just dust it with a rag then put the prefilter on.
