Complete Formation: What are the filtration stages inside iSpring RCC7AK?

So, let’s talk about the various stages inside the filter. From the product’s full name “iSpring RCC7AK 6 stage water filter” you can easily realize that it comes with six stages to purify water.

  • In the next few sections, we’ll be clearing up about all these stages. We’ll be covering what’s inside those? How do they work? And many more.

But, let’s first see at a glance what are the various stages inside the iSpring RCC7AK water filter.

Now, let’s find out how all these stages work altogether to provide us clean, odorless freshwater.

The first three stages work to remove Dust, Chlorine, and taste

The first stage consists of a strong sediment filter. You can certainly guess what it does.

  • The sediment filter clears out all the dust, clay, or sand particles that might come floating with the tap water.

This one can be particularly handy when you’re using water from a private well. Even tap water can sometimes contain microscopic particles from debris.

iSpring RCC7AK prefilters remove all the dust, rust and clay particles

That’s why the first stage which is the sediment filter works like a sieve to trap those undesired particles. 

After filtering out the dust particles, water flows into the next stage. This stage consists of a granular activated carbon filter.

  • The activated Carbon fragments lure in harmful chemicals and attach those into the surfaces. To increase the surface area, Carbon is pulverized to produce small scraps.

Increasing the surface, the Carbon particles become more active. That’s why we call them granular activated Carbon. This one works to pull out the organic materials from water.

After this comes the CTO filter. The word CTO stands for Chlorine, Taste, and Odor. So, this one filters out most of the Chlorine, odor, and other chemicals from the water.

Again, in this case, you will see Carbon, but in a different shape. Here, you’ll find activated Carbon staying in a block like formation.

  • The Carbon block remains on the pathway of water. And, therefore, the water has to flow axially through it. In turn, Chlorine, Sulphide, Fluoride- chemicals like gets trapped.

This one also gets rid of any bad taste or odor from the water. In this fashion, these three stages work to partially remove detrimental chemicals.

The RO membrane and the inline Carbon filter removes the rest of the pollutants

The sediment filter along with the GAC and CTO filters set up the pre-filter stage. They remove Chlorine, Arsenic, and most of the insoluble organic pollutants.

To get rid of the soluble particles from the water, there is the RO chamber. You can think of it as the powerhouse of the water filter.

  • The word “RO” stands for reverse osmosis. This is considered the most effective purification process of water.
iSpring RCC7AK RO membrane removes all harmful pollutants

That’s why you’ll find one in most of the modern water filters out there.

The heart of the RO chamber is the RO membrane. This membrane has a special nature that allows it to filtrate the pollutants from the water.

What’s the specialty? The answer is it only lets water molecules pass.

  • As a result, if the water contains substances that dissolve, those substances will not be able to pass the membrane.

If you’re still curious, you can visit our post here. In this post, we’ve explained the science behind reverse osmosis and how it purifies water. You’ll surely enjoy it.

After the RO membrane, there is another inline Carbon filter that works to remove all the remaining Chlorine and other chemicals if there is any.

  • As the water might temporarily remain in the tank after the RO membrane, it also works to remove any dirt that might be inside the water tank.

In this way, the RO membrane and inline Carbon filter work to purify the water from the prefilters. 

Remineralization stage: Adding minerals back into the water

The next and final stage is the alkaline or mineralization filter. As the name suggests, it restores the lost mineral contents into the water.

  • Water that you get from the RO stage loses out most of the minerals like Calcium or Magnesium ions. These are some of the vital nutrients of our bodies.

So, adding minerals back into the water is very significant for health-related concerns. This also gives the water the right pH level.

  • According to several research, water from RO filters can be acidic at times. So, this can pile up on your gastric acidity problems.

As a result, people now prefer these RO-alkaline filter combinations over just RO water filters. That’s why iSpring RCC7AK stands out among the crowd.

So, if you want to get fresh and clean water with adequate minerals, you should give this iSpring water filter some consideration.

Maintenance: How often should you replace the cartridges of the iSpring RCC7AK water filter?

The last thing we want to shed light on is the maintenance of the water filter. As you can see, the water filter consists of a variety of cartridges, you need to replace them regularly.

But, how often? This one mostly depends on the quality and TDS (total dissolved solids) of the water. 

  • On average, the first sediment filter will last for about 6 months in the case of iSpring water filters.

The activated carbon blocks – GAC, CTO, and inline post Carbon filter can last up to 1 year. As a result, you should replace those within 1 year.

On the other hand, the RO membrane will last longer. If used properly, it will serve you 2 to 3 years straight.

Last but not least, you should replace the alkaline or mineral filter every 6 months.

All these apply for cartridges that come with the package. You can purchase 1-year, 2-year, or 3-year replacement filter packages on Amazon. Check out the table below.
