NU Aqua Platinum Series 100GPD (6-Stage Alkaline Undersink RO System)

How does the alkaline remineralisation process work?

The alkaline stage uses five different media types to restore beneficial minerals. Bio ceramic media increases oxygen levels in water molecules. Tourmaline begins alkalisation and acts as a supercharger for subsequent stages. Calcite boosts alkalinity and neutralises acidity from dissolved carbon dioxide. Maifan stone provides ion exchange whilst absorbing heavy metals and adding calcium, iron, zinc, magnesium, copper and selenium. Finally, ORP balls create antioxidants and enhance pH balance for optimal health benefits.

What contaminants does this system remove from water?

The 6-stage filtration removes sediment, chlorine, chloramines, heavy metals, dissolved solids, bacteria, viruses and other harmful contaminants. The reverse osmosis membrane eliminates particles down to 0.0001 microns. Pre-filters handle larger particles and chlorine whilst carbon filters remove taste and odour compounds. The system reduces TDS levels significantly - users report reductions from 378 PPM to 18 PPM in city water supplies.

How long does installation typically take?

Installation takes less than one hour for most people using the included manual and colour-coded components. The system uses quick-connect fittings that require no special tools or plumbing experience. All necessary components are included except basic tools. The clear instructions and colour-coded tubing make the process straightforward. Some users recommend watching online installation videos for additional guidance during setup.

What are the ongoing maintenance requirements?

Filter replacement schedules vary by usage and water quality. Pre-filters typically need changing every 6-12 months, whilst the RO membrane lasts 2-3 years. The alkaline filter requires replacement annually. The clear first-stage housing allows visual monitoring of filter condition. Regular maintenance ensures optimal performance and water quality. Replacement filters are readily available and easy to change using the quick-connect system.

How much water pressure is required for proper operation?

The system operates effectively with water pressure as low as 40-45 PSI, though higher pressure improves performance. Standard household water pressure of 60-80 PSI provides optimal flow rates. Low pressure situations may benefit from adding a booster pump for maximum efficiency. The system includes pressure regulation to protect components whilst maintaining consistent output regardless of input pressure variations.

What's included in the complete system package?

The package includes all filtration components, storage tank, NSF-certified stainless steel faucet, quick-connect fittings, colour-coded tubing, installation hardware and detailed manual. A complimentary PPM meter is included for testing water quality. Installation DVD provides visual guidance. All necessary components for complete installation are provided except basic household tools. The 3-year warranty covers all included components.

How does this compare to bottled water costs?

The system typically pays for itself within 4 months compared to bottled water purchases. A family spending £20-30 monthly on bottled water saves hundreds annually with home filtration. The system produces water at approximately 2-3 pence per gallon versus £1-2 per gallon for bottled water. Over the 3-year warranty period, savings can exceed £1,000 whilst providing unlimited clean water access.

Can this system be used with well water?

Yes, the system works effectively with well water up to 5,000 PPM TDS levels. Well water often contains higher sediment and mineral content, which may require more frequent pre-filter changes. The system handles iron, sulphur and other common well water contaminants. Users with particularly challenging well water may benefit from additional pre-treatment. The alkaline stage helps balance pH levels often found in well water supplies.
