Kent NL7 Reverse Osmosis Water Filtration System

Stage 1: Sediment Pre-Filter Removes sand, silt, rust, and fine particles that can clog downstream filters and the RO membrane - protecting the system and extending filter life.

Stage 2: Carbon Block Pre-Filter Removes chlorine, chloramine, volatile organic compounds (VOCs), and chemical residues from city water - protecting the RO membrane from chlorine damage and improving overall water quality before the membrane stage.

Stage 3: NewLine Patented Pre-Filter The NL7's proprietary NewLine cartridge provides an additional stage of advanced prefiltration using patented technology - delivering increased filtration capacity compared to standard pre-filter designs.

Stage 4: RO Membrane The high-precision reverse osmosis membrane removes dissolved impurities including lead, heavy metals, nitrates, arsenic, PFAS, and total dissolved solids - reducing contaminants that pre-filters and carbon filters cannot address. Membrane life: 8,000-20,000 gallons.

Stage 5: Carbon Post-Filter A final activated carbon post-filter removes any residual taste and odour after the RO membrane - polishing the water before the remineralization stages.

Stage 6: Remineralization Cartridge The remineralization cartridge adds back essential calcium and magnesium minerals in balanced proportions - improving taste, solubility, and the overall drinking experience. Cartridge life: 2,000 gallons.

Stage 7: Bioceramic Activator The bioceramic activator uses infrared ceramic technology in the final stage to further enhance water quality and taste - delivering finished water that is noticeably smoother and more refreshing than standard RO water.

For Southern Ontario homeowners who want the highest quality drinking water at home, the Kent NL7 is a compelling long-term investment. City water across the GTA - while safe to drink - contains residual chlorine, chloramine, and varying levels of dissolved solids that affect taste and odour. The NL7 addresses all of these at the point of use, producing water that is consistently better-tasting than tap water and comparable to or better than premium bottled water - at a fraction of the per-litre cost. The remineralization and bioceramic stages set the NL7 apart from basic RO systems - providing mineral-balanced water rather than stripped, flat-tasting purified water.

At $14.95/month it is the most affordable way to have genuinely premium drinking water on demand from your kitchen tap - without the cost, inconvenience or environmental impact of bottled water. For well water homes, the NL7 is typically installed as a final point-of-use stage after whole-home filtration and softening, providing the highest level of purification for drinking and cooking water.
