The Nimbus system uses not only the 30GPD reverse osmosis membrane filter, but a high-capacity pre-filter and carbon post-filter. The pre-filter removes dirt, rust and other suspended solids as well as chlorine taste and odor. The carbon post-filter is the last step to give you fresh tasting, clean and clear drinking water for your home.
This filter replaces filter #1 as indicated in the above picture. The pre-filter should be replaced every 6-9 months.
