Although most people don’t realize it, tap water often contains a lot of impurities that make it less safe for consumption. Some of these impurities like dirt and bacteria might be obvious, while others like lead and fluoride are not.
While boiling the water will definitely remove most of the harmful substances, it will take a lot of time and energy. So what is the next best thing that comes close? Simple – a reverse osmosis filter!
You’ve probably heard one or two things about reverse osmosis, especially about how effective it is for purifying drinking water in the home.
You may have also heard that they can remove beneficial minerals while taking out contaminants and produce water that is slightly acidic.
Imagine a filter that can put back the good stuff that was taken out by reverse osmosis? Yes, that’s exactly what the iSpring Water Filter does.
If you’re looking for the best RO system out there, then you should consider the iSpring RCC7AK with its 6-stage filtration system. But can this filter really remineralize water? How effective is it? Is the price worth it?
Today we will be answering all these questions and more with our iSpring water filter review.
Apart from its great price, the iSpring RCC7AK brings a lot to the table, which makes it a popular choice among homeowners. Below are the features of the product we find most attractive.
If you consume bottled water occasionally, you would have noticed that it doesn’t taste like your normal tap water. Have you ever wondered why? The answer is simple – filtration.
Like we mentioned earlier, tap water often contains a lot of particles and chemicals. This is why an efficient filtration system is required to take them out.
Luckily, the iSpring RCC7AK has been specifically designed to meet this need.
The system uses a 6-stage filtration process to purify water and make it safe for drinking. Each of these stages plays a specific role in the whole treatment process, which is explained below:
- The first filtration stage consists of a sediment filter whose job is to remove the sediments and particles in the water. This may include dust, rust, dirt, sand, and what have you.
- The second filtration stage features a 5-micron granular activated carbon filter, which helps to improve the taste, odor, and clearness of the water. It is at this stage that chemicals like chlorine are removed.
- The third filtration stage also works on the aesthetics of the water, helping to remove residual taste and color.
- The fourth stage is where the main reverse osmosis takes place. It contains an RO membrane that removes all dissolved solids and other contaminants and bacteria.
- The fifth filter stage also works on the taste and odor to produce clean and crisp water.
- The final stage is equipped with an alkaline filter that balances the water PH and adds useful minerals such as calcium and magnesium.
Apart from its excellent filtration system, another thing you will like about the iSpring RCC7AK is its low noise level. This should come as a relief, given the fact that most RO filters in the market are known for being notoriously noisy. Much of this can be attributed to its efficient modern design.
It will also interest you to know that the filter delivers up to 75 gallons of water in a single day. Now combine this with its 2:1 waste water ratio, and you have one of the most efficient filter systems available.
Many similar models have a waste to pure water ratio of 4:1, which means for every single gallon of purified water produced, four gallons from your water supply is wasted. This makes the iSpring RCC7AK a gem for families.
One of the major features that separate the iSpring RCC7AK from most of its counterparts is its ability to reclaim minerals lost during the filtration process.
Most RO membranes eliminate contaminants and dissolved solids, and stops there. However, the membrane used in the iSpring RCC7AK goes a step further. It enriches the filtered water with natural minerals like magnesium, calcium, and potassium. This makes the system an excellent fit for producing great tasting water at home.
However, there’s no way to know how much mineral is added back to the water; we can’t prove that the filters are completely efficient. But we are sure they come close.
Easy Installation and Maintenance
The installation of the iSpring RCC7AK is quite straightforward. Anyone with some basic DIY skills should be able to do it. The instruction manual is quite intuitive, so you should be able to get along well, even if you have no experience.
Before starting the installation, we strongly recommend watching the video provided by the manufacturer. The video also shows you how to replace the filter cartridges.
If, after going through the manual and video, you still don’t feel confident enough to carry out the installation on your own, you can always hire a professional. It’s very important that you get the installation right in order to prevent possible leaks.
Luckily, the system doesn’t require much maintenance. You will need to change the filters after every 3-6 months. Some users have complained of a shorter lifespan, but this mostly happens when the water is very contaminated.

How Do I Change My iSpring Filter?
The iSpring RCC7AK comes with cartridge-type filters, which are quite easy and quick to change, though they still require more effort than the modular filters found in Home Master systems. Modular filters obviously come first when it comes to simplicity and usage.
Moreover, the RCC7AK cartridge filters are housed in a transparent plastic holder. To change them, you will need a plastic spanner and some Vaseline. Don’t worry, the spanner is usually provided with the system. Just follow these steps:
- To carry out any filter change, start by loosening the housing using the plastic spanner provided.
- Once the housing is loose, you can finally unscrew with your hands and then remove the old filter. It’s normal if the water is spilled in the process.
- Now, push in the new filter into the empty filter space and rub some Vaseline on the “O” ring. Next, attach the housing and screw it back again.
- Use the plastic spanner to tighten the whole thing again.
Why Do You Need iSpring Water Filter Replacement?
The filters used in RO systems are not everlasting. Once in a while, they will be due for replacement and thus need to be replaced. Changing the filter is necessary to ensure the proper functioning of the filtration system.
Over time, filters get clogged by dirt and debris and thus lose their efficiency. This affects the general performance of the whole unit and the quality of water being produced. And at some point, you will have no choice but to change the filters.
Most filters will last for 1 to 3 years, depending on the quality of your water supply.
You can use a TDS meter to check if a filter is due for replacement. A TDS below 90 percent means your filter needs to be changed.
To conclude our iSpring water filter review, this unit is a must-have if you want a filter system that doesn’t only filter contaminents from water but also replenishes lost minerals. It is efficient and less noisy.
So much has already been said about it being one of the best RO filters out there, and we couldn’t agree more. This is evident from the huge number of positive reviews it has received online.
