Prices for the iSpring RCC7AK
Having looked at the overall performance, let’s consider the cost of installing this filtration technology.
The different models and options available
The standard RCC7AK package stands out as a complete solution. Unlike the classic RCC7 model, this version includes an AK cartridge. We believe that the addition of remineralisation more than justifies the slight price difference between these two systems.

The initial cost covers a ready-to-use kit. This includes the tank, the dedicated tap and all the filters. Everything is included to allow for immediate installation with no hidden costs as soon as you unpack it.
Some variants feature a built-in booster pump. This is a key feature if your mains water pressure is too low. Indeed, maintaining the recommended PSI is essential to ensure optimal performance and minimise water wastage.
Spare parts are readily available online, and you can take advantage of the current offer to secure your installation right now.
Our view on the price of the iSpring RCC7AK
We find the value for money particularly good. Compared to European systems, which are often more expensive, the iSpring boasts equivalent NSF certifications. It is a serious alternative for protecting your health without emptying your savings account.
ℹ️ Maintenance costs
The estimated annual cost is around $95. This budget includes the regular replacement of filters for standard family consumption.
Annual maintenance costs are therefore kept well under control. When you calculate the average price of filter sets over twelve months, you realise that maintenance is far less expensive than buying consumables for standard filter jugs.
The cost-effectiveness is clear when compared to bottled water. For a family of four, the savings made on packs of mineral water make this purchase a smart and eco-friendly financial investment.
The initial investment pays for itself in less than a year for a household that regularly consumes bottled mineral water.

Now that the cost has been clarified, it is worth considering whether your consumption profile matches the specific features of this reverse osmosis system.
This system is ideal for homeowners looking for a sustainable under-sink solution. We particularly recommend it to health-conscious families. It effectively removes heavy metals and PFAS. Your household thus benefits from maximum safety.
Tea and coffee lovers will be delighted. The remineralised water enhances delicate flavours. It avoids the usual acidity associated with conventional reverse osmosis. Your hot drinks *finally regain their true flavour*.
We recommend this model for DIY beginners. The quick-connect fittings make installation much easier. However, it is less suitable for tenants. Drilling into the sink often requires permission, which you may not necessarily have.
It is an ideal solution for areas with hard water. The system protects your small appliances from premature limescale build-up. Your kettle will stay clean for much longer. You gain in convenience and the longevity of your appliances.
iSpring offers high-performance whole-house filtration solutions. Their expertise guarantees healthy water from every tap.

List of features
To understand how effective this model is, let’s delve into the technical details of its unique filtration system.
A 6-stage NSF-certified filtration process
The system begins with three robust pre-filtration stages. A sediment filter traps coarse particles, whilst granular activated carbon and a carbon block protect the membrane.
At the heart of the system is an iSpring semi-permeable membrane that rejects contaminants, such as lead or arsenic, directly into the drain to ensure maximum purity.
A coconut carbon finish filter then comes into play. It removes any remaining tastes after the water has passed through the pressurised tank, ensuring impeccable freshness.
NSF/ANSI 58 certification provides solid proof of performance. It guarantees a real and verified reduction in lead, fluoride and arsenic for your safety.
- 5-micron sediment filter
- GAC carbon
- CTO carbon
- 75 GPD RO membrane
- Post-carbon
- AK filter
Alkaline remineralisation for healthy water
The AK cartridge, which stands for Alkaline Remineralisation, radically transforms the experience. It restores the water’s natural balance by adding ionised calcium and magnesium after reverse osmosis filtration.
Drinking slightly alkaline water has health benefits. It helps neutralise the body’s acidity and improves daily cellular hydration for the whole family.
On the palate, the difference is striking compared to conventional systems. The resulting water resembles bottled spring water, without the flat taste typical of standard reverse osmosis systems.
You can consult our guide to the best reverse osmosis systems to compare these cutting-edge technologies with other models on the market.
This remineralisation stage is also technical. It helps prevent pipe corrosion by stabilising the water’s pH, which is often too acidic when it comes out of the membrane alone.
DIY installation and maintenance under the sink
Installing this iSpring RCC7AK is made easy by its clever design. The use of colour-coded tubes and ‘push-fit’ quick-connect fittings makes assembly straightforward without the need for complex tools.
Pressure management is something to keep an eye on. The system requires between 45 and 70 PSI to operate optimally without the need for an additional pump.
To save space, a simple tip is to position the tank to the side. This frees up valuable space for your cleaning products under the kitchen sink.
| Step | Frequency | Difficulty |
|---|---|---|
| 3 pre-filters | 6–12 months | Easy |
| RO membrane | 2–3 years | Medium |
| AK filter | 12 months | Easy |
Don’t forget the initial rinse when starting up. It is essential to empty two full tanks before using the water to remove any manufacturing residue.
💡 Please note
The initial rinse is mandatory: empty two to three full tanks before first use to remove sediment and the initial plastic taste.
Customer reviews
Beyond the technical specifications, let’s see what users think of this system after several months of actual use.
There is plenty of positive feedback regarding this reverse osmosis system. Users often highlight the complete disappearance of the chlorine taste. The clarity of the water is also a recurring highlight. You thus get a pure and healthy drink.
There are, however, a few points to watch out for. Reports of leaks around the tap do occasionally surface. This happens if the seal isn’t tightened properly during assembly. So do take care during installation.
Satisfaction with after-sales service is almost unanimous. Customers appreciate the responsiveness of the support team on the official iSpring website in resolving issues. This technical support is a huge reassurance for hesitant buyers.
