RODI micron question

[Myka]

Check out the "New to the Hobby" forum. I just posted an article about RO/DI systems a few days ago that talks about filter choices.

I like to match the microns of the sediment filter to the microns of the carbon filter. If you want to use 1 micron carbon filter then I would choose a 1 micron sediment filter. If the sediment filter clogs up too fast, then you can either a) deal with it because those filters are inexpensive, or b) add a second sediment filter so you can use a 5 micron ahead of the 1 micron. I do prefer to use 1 micron filters. 1 micron carbon filters are much more effective than 5 micron carbon filters.
