Langwater TheWell 2 Reverse Osmosis Water Filter (Peach, Countertop)

What contaminants does this system remove?

The 4-stage filtration removes up to 99.9% of over 1000 contaminants including heavy metals, microplastics, PFAS (forever chemicals), hormones, pharmaceuticals, pesticides and medicine traces. The NSF58-certified reverse osmosis membrane handles dissolved solids whilst UV sterilisation eliminates bacteria and viruses. The sediment and carbon pre-filters capture larger particles and chlorine, providing comprehensive water purification.

How long do the filters and mineral cartridges last?

The RO membrane lasts approximately 2 years or 3000 litres, whilst sediment and carbon filters need replacement after 1 year or 1500 litres. Filter lifespan depends on your water's TDS levels - harder water reduces filter life. One LANGPAK mineral cartridge mineralises 250 litres of water. The system monitors usage and alerts you when replacements are needed through the app and display.

Is installation required and how much maintenance is needed?

No plumbing installation is required - simply plug in and fill the water reservoir. The system is designed for minimal maintenance with self-cleaning features. Daily hot water rinse cycles can be automated and descaling is only needed when prompted by the system alerts. Regular maintenance involves emptying and refilling the input reservoir and occasional cleaning with the provided descaling cartridge.

Can I use the system without adding minerals?

No, mineral cartridges are mandatory for operation. The system will not function without LANGPAK mineral cartridges installed. This is intentional as pure RO water lacks essential minerals and can taste flat. The minerals are natural salts in liquid form with no additives, designed by water sommeliers for optimal taste and health benefits. The sodium-free formula is Swiss-made and food-grade certified.

How much water does the system waste and what's the energy consumption?

This system achieves 70% water efficiency with a 2.3:1 ratio, meaning for every 2.3 litres of input water, you get 1 litre of purified water. This is significantly better than traditional RO systems that typically waste 3-4 litres per litre produced. Energy consumption is minimal at 0.004 kWh per litre, making it environmentally friendly and cost-effective for daily use.

What flavour options are available and how do they work?

Natural fruit flavour cartridges are available in lemon, orange and peach varieties. These contain zero sugar, zero calories and no artificial additives - just natural fruit extracts. Flavour intensity is adjustable through the app or touchscreen. The flavours are dispensed using the same liquid delivery system as minerals, ensuring consistent taste throughout each glass of water.

How fast does the system produce water and what's the capacity?

The system produces 1 litre of filtered water in under 2.5 minutes with a maximum flow rate of 0.4 litres per minute. The input reservoir holds 2.5 litres, sufficient for multiple servings before refilling. Three automatic fill levels are available based on glass position and dispensing can be stopped at any time. The compact 21cm width fits most countertops whilst the 47cm height accommodates standard glasses and bottles.

What smart features and controls are included?

The system includes both touchscreen interface and smartphone app control. Monitor real-time TDS levels, adjust mineral dosage and flavour intensity, select water temperature up to 100°C and customise delivery volumes. The app provides filter life tracking, maintenance alerts and software updates. Self-cleaning cycles can be scheduled and the system remembers your preferences for consistent water quality and taste.
