About this item
- Individually wrapped, 6-month filter replacement cartridge pack for iSpring PH100 and most industry standard 10” 6-stage reverse osmosis RO systems. Made in the US.
- Alkaline Remineralization Filter: Restores minerals and produces a balanced alkalinity.
- Sediment Water Filter: Works as the first barrier in the reverse osmosis system by removing solid particles like silt, rust and dirt from the water and reducing a significant percentage of contaminants in the water. This prevents the other filters from getting clogged with fine particles and reduces the risk of damage to the other parts of the filtration system.
- Granular Activated Carbon Filter: Includes carbon media that filters out impurities in the water. This protects and prolongs the lifespan of the reverse osmosis membrane.
- Carbon Block Filter: Activated carbon filters trap and absorb chemicals and chlorine from the water.
- 4 pack of 10” x 2.5” replacement water filters included: 1x Alkaline Remineralization filter, 1x Sediment Filter, 1x Granular Activated Carbon Filter and 1x Carbon Block Filter. All filters are made in the USA.
- Note: This filter pack does NOT include an RO membrane.
