Sediment Filter
The Sediment Filter works as the first barrier in the Reverse Osmosis System, removing solid particles like silt, rust and dirt from the water and reducing a significant percentage of contaminants in the water. It prevents the other filters from getting clogged with fine particles and reduces the risk of damages to the other components.
iSpring’s first stage Sediment Filter (FP15) features a 5 micron size, perfect for capturing most of the fine sediments in the municipal water and preventing issues from clogs and pressure loss with filters that have smaller micron sizes.
Granular Activated Carbon Filter
Activated Carbon filters can trap and absorb organic chemicals and chlorine from the water effectively with its ability of mechanical filtration and physical adsorption. It can efficiently remove odors and improve the water taste.
Furthermore, the iSpring 2nd stage Granular Activated Carbon (GAC) filter (FG15) includes special carbon media that filters out impurity in the water, which can efficiently protect and prolong the lifespan of the reverse osmosis membrane.
Carbon Block Filter
Activated Carbon filters can trap and absorb organic chemicals and chlorine from the water effectively with its ability of mechanical filtration and physical adsorption. It can efficiently remove odors and improve water taste.
Post Carbon Filter
Activated Carbon filters can trap and absorb organic chemicals and chlorine from the water effectively with its ability of mechanical filtration and physical adsorption. It can efficiently remove odors and improve the water taste.
iSpring 5th Stage Post Carbon filter (FT15) works as the final stage in the RO system to capture any particles that may have accumulated inside the tank before pure water is delivered to the faucet. It can last up to 12 months depending on your source water and usage.
