Includes 7 total reverse osmosis water filter cartridges - 2 sediment filters, 2 granulated activated carbon filters, 2 carbon block filters, and 1 post carbon filter (iSpring FT15) for polishing.
Sediment, carbon block and granulated activated carbon filters help remove contaminants like dirt, rust, chlorine and organic contaminants that cause bad taste and odor.
The iSpring FT15 post carbon filter provides a final polish to improve water taste and clarity before delivery to the faucet.
Fits most standard 5-stage reverse osmosis systems including iSpring, Flowmatic, PuROLine, Crystal Quest and Apec models.
Replace filters approximately every 6 months, except for the post carbon filter which lasts around 12 months.
