Complete set of 6 PREMIUM reverse osmosis filters, 6 stages – replacement cartridges PP + GAC + CTO, 75 GPD RO membrane, MINERAL post-filter (remineralization), GAC post-filter – Spectrum Water BLUE Series

The Spectrum Water BLUE set is designed for 6-stage reverse osmosis systems and is the ideal choice for users who want not only purified water, but also remineralized water balanced for daily consumption. Through a well-balanced combination of mechanical pre-filtration, activated carbon filtration, and a reverse osmosis membrane, the water is purified from sediments, chlorine, organic substances, and dissolved impurities, resulting in clear, safe water with a pleasant taste. By adding the remineralization filter, the water produced after reverse osmosis is enriched with essential minerals, achieving a more natural taste and a composition closer to spring water.

Set components

• SED – PP cartridge (SED) – 5 microns – polypropylene mechanical filter that retains solid particles such as sand, rust, silt, sediments, and coarse impurities. It protects the following stages and extends the service life of the RO membrane.
• GAC – GAC granular activated carbon cartridge – activated carbon filter that reduces free chlorine, chlorination by-products, and volatile organic compounds. It significantly improves the taste, smell, and clarity of the water.
• CTO – Carbon Block – compact activated carbon filter that removes residual chlorine, retains fine organic matter, and protects the reverse osmosis membrane. It provides deeper filtration compared to GAC.
• ROM 75 GPD – RO reverse osmosis membrane – 75 GPD – the main component of the system, responsible for reducing dissolved salts, removing heavy metals, and reducing nitrates, bacteria, and other contaminants. Filtration capacity: 75 GPD (gallons/day) (284 liters/day).
• MIN – MINERAL post-filter (remineralization) – adds natural minerals such as calcium, magnesium, and potassium to purified water. It contributes to a balanced taste and a more stable pH.
• POST GAC – Post granular activated carbon filter made from coconut shell – the final water polishing stage: improves the final taste, removes residual odors, and provides pleasant-tasting water. Ideal for drinking and cooking.
