Complete set of 5 PREMIUM reverse osmosis filters, 5 stages – replacement cartridges PP + GAC + CTO, 75 GPD RO membrane, GAC post-filter – Spectrum Water WHITE Series

The Spectrum Water WHITE set is a complete package of replacement filters for 5-stage reverse osmosis systems, designed for efficient drinking water purification and for maintaining optimal system performance. Through a balanced combination of mechanical pre-filtration, activated carbon filtration, and a reverse osmosis membrane, the water is purified of sediments, chlorine, organic substances, and dissolved impurities, resulting in clear, safe water with a pleasant taste.

Set components

• SED – PP cartridge (SED) – 5 microns – Mechanical polypropylene 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 – Filter with a compact activated carbon structure that removes residual chlorine, retains fine organic matter, and protects the reverse osmosis membrane. It provides deeper filtration compared to GAC.
• ROM 75 GPD – Reverse osmosis membrane (RO) – 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).
• POST GAC – Coconut shell granular activated carbon post-filter – The final water polishing stage: improves the final taste, removes residual odors, and provides pleasant-tasting water for consumption. Ideal for drinking and cooking.
