List of key system features
To understand why this model is such a hit, you need to lift the lid and take a look at the technology inside.
5-stage filtration and 75 GPD membrane
The first three pre-filters (PP, GAC and CTO) act as a shield. They block sediment and neutralise chlorine. This effectively protects the reverse osmosis membrane.
The 75 GPD RO membrane is the real defence against heavy metals. It removes up to 99% of impurities such as lead or arsenic. This is the secret to getting healthy water every day.
Finally, the carbon post-filter comes into play just before the water reaches your glass. It removes any remaining odours. Your water thus regains a perfectly neutral and very pleasant taste.
If you’re still unsure which model to choose, take a look at our review of the iSpring RCC7AK alkaline osmosis system. This will allow you to compare performance.
DIY installation and pressure management
The quick-connect fittings on this unit are designed to fit standard plumbing fittings. We’ve found that this significantly reduces the risk of leaks during installation. The installation is straightforward for DIY enthusiasts.
The inlet pressure must be between 40 and 100 psi for optimal performance. If your domestic water pressure is too low, performance will suffer. A booster pump would then be necessary.
To save space, we recommend fixing the filter unit directly to the side of the unit. This makes it easier to fit the 10.6-litre tank. Organising the space under the sink then becomes a breeze.
💡 Commissioning tips
- Check the water pressure (40–100 psi)
- Have Teflon tape to hand for sealing
- Rinse the filters for 20 minutes before drinking
Rejection ratio and material certification
The 1:2 waste ratio is a major plus for this model. For every litre of purified water produced, only two litres are flushed away. This is a very reasonable trade-off to keep your water bills down.
The tap supplied is made from lead-free brass, ensuring complete safety. This is a detail often overlooked by entry-level brands. Here, the user’s health is taken very seriously.
Quick-connect fittings make it easy to change cartridges in future without the need for complicated tools. Maintenance becomes quick and stress-free. The robustness of the unit inspires real confidence in the long term.
The storage tank is NSF-certified, ensuring optimal food-grade quality. Water is stored without any migration of harmful substances.

Points to note and technical feedback
The space required under the sink is a major consideration. The 10.6-litre tank takes up a significant amount of space in the kitchen cupboard.
Sealing during installation requires particular attention. Some users report micro-leaks if the tubes are not pushed in as far as they will go.
The quality of the plastics sometimes raises concerns. A few reviews highlight the apparent fragility of the tightening key supplied for the casings.
💡 Technical warning
Risk of micro-leaks if the tubes are not fully pushed in. Be aware of the fragility of the tightening key. Allow space for the tank (H 36.6cm x D 24cm).
Assembly requires patience, especially to ensure the quick-connect fittings are perfectly sealed on the first attempt.
