Now that we’ve got the formalities out of the way, let’s get down to the nitty-gritty. What’s the iSpring RCC7AK all about? In the simplest terms, it’s a Reverse Osmosis system designed to transform your tap water into something that rivals bottled water. Imagine turning on your faucet and getting water that’s not just clean but also remineralized, ensuring it’s packed with essential minerals. Yup, that’s what this system does.

What makes it particularly special is its 6-stage filtration process. Most RO systems stop at purification, but the iSpring RCC7AK goes the extra mile with a sixth stage—the Alkaline Remineralization filter. This final stage restores essential minerals like calcium, magnesium, and potassium, making your water not just pure but also healthier and tastier.

Alright, so is it any good? Spoiler alert: It’s more than just ‘good.’ This system is NSF/ANSI 58 certified, which is pretty much the gold standard for water filtration systems. That means it’s gone through rigorous testing to ensure it does exactly what it says—remove up to 99% of over 1,000 harmful contaminants from your water. The peace of mind that comes with that certification? Priceless.

But let’s not overlook its daily production capacity of 75 gallons. Unless you’re filling up a swimming pool with RO water (and hey, we won’t judge if you are), this system has got you more than covered. It effortlessly meets the water needs of a larger household, making it not just an efficient but also a highly practical choice.

iSpring RCC7AK Reverse Osmosis Filtration Capabilities

We’ve talked about what this device does, but how does it work, exactly? Well, strap in, because the iSpring RCC7AK’s filtration game is strong. Really strong.

Let’s start with the big number: 99%. That’s the percentage of over 1,000 contaminants this system claims to remove from your water. And it’s not just making lofty promises; it’s got the NSF/ANSI 58 certification to back that up. Lead, fluoride, chlorine, arsenic, you name it. These are not things you want in your water, and the iSpring RCC7AK ensures they don’t make it to your glass.

So, how does it achieve this level of filtration? Through its 6-stage filtration process, that’s how:

  • Stage #1: Consists of a PP Sediment filter, that removes sediments, dust, sand, dirt, rust, and other larger particles
  • Stage #2: Consists of a Granular Activated Carbon, that removes chlorine, cloudiness, bad taste & odors
  • Stage #3: Consists of a Carbon Block, that removes chloramine, VOCs, harmful contaminants, etc.
  • Stage #4: Consists of a Reverse Osmosis Membrane with 0.0001 microns, which removes a huge amount of contaminants
  • Stage #5: Consists of a Post Carbon, that improves water taste by removing any potential bad taste & odors from the storage tank
  • Stage #6: Consists of an Alkaline Filter, that increases water alkalinity adding back beneficial minerals

Most RO systems you’ll find on the market have a 5-stage filtration process. The iSpring RCC7AK one-ups them with an additional Alkaline Remineralization stage. This stage balances the pH level of the water and restores essential minerals. In layman’s terms, it makes the water healthier and yummier.

“But what if my water has microbes?” I hear you ask. Well, the iSpring RCC7AK has got you covered there too. While the model we’re focusing on doesn’t come with a UV sterilizer, the iSpring RCC7AK can be easily upgraded to include a UV stage. This takes the purification game to the next level, killing any bacteria and viruses that might have survived the previous stages.

iSpring RCC7AK Reverse Osmosis Performance

So, you’re curious about the iSpring RCC7AK’s performance, huh? Let’s dive in. When it comes to waste water ratio, the system stands at a pretty standard 1:3. In layman’s terms, that means for every gallon of purified water, there are three gallons of wastewater. While it’s on par with the industry average, there are more efficient options out there.

Don’t get me wrong, this system still rocks in its own right, but if you’re particularly concerned about water waste and sustainability, there are other RO systems out there that boast more eco-friendly waste water ratios, like 1:1 or even 2:1. Because, hey, saving water means saving money and giving Mother Earth a helping hand, am I right? 🌍

iSpring RCC7AK Reverse Osmosis Capacity

The iSpring RCC7AK has a commendable production rate of 75 gallons per day (GPD), which should adequately serve the daily water needs for most households. But wait, there’s a little twist: the system has a flow rate of just 0.03 gallons per minute (GPM). That means you might find yourself counting seconds when filling up that glass of water or a cooking pot. 🕒

Now, let’s talk storage. The system comes with a tank that can hold up to 3.2 gallons of filtered water. This storage capacity, combined with the production rate, ensures that you won’t run out of clean water—even on the busiest of days. However, the slower 0.03 GPM flow rate could mean a bit of a wait, so plan your high-volume water needs accordingly.

75 gallons of water per day is more than enough for most families, so this system capacity should not be a problem for you. Anyway, you can always estimate how much clean water your family will need using our water usage calculator.

iSpring RCC7AK Reverse Osmosis Design Features

The iSpring RCC7AK is a classic undersink Reverse Osmosis system. Now, why does that matter? Because its undersink design means it won’t hog precious countertop space, and it stays out of sight while doing its magic. The one downside? You’ll need to have enough cabinet space underneath your sink to accommodate the system, including its 3.2-gallon tank.

As for its look and feel, the system boasts a clean, no-fuss design with an elegant brushed nickel faucet. This little design touch ensures the system complements a wide variety of kitchen aesthetics, from modern to rustic.

You know what else is neat? The system includes an automatic flushing feature, which reduces the build-up of harmful contaminants on the filter and prolongs its life. This is a handy addition that can save you time and energy in the long run.

One noteworthy feature is the transparent housing for the system’s first-stage filter. This see-through design lets you visually inspect the sediment filter, making it super easy to identify when it’s chock-full of contaminants and ready for a swap-out. 🕵️‍♂️

But that’s not all. For those of us who’ve ever had to deal with water damage (trust me, it’s no fun), the iSpring RCC7AK comes equipped with a leak detection system. The moment it senses excess water, it shuts off the entire system. It’s like a guardian angel for your under-sink cabinet and, by extension, your wallet.

And speaking of avoiding leaks, the system incorporates leak-free fittings and a 4-color tube set, which not only aids in a hassle-free installation but also ensures the system stays leak-proof.👌

First off, you’ll be replacing a few different filters at various intervals throughout the year:

The sediment filter, Granular Activated Carbon filter, CTO Carbon Block filter, and the alkaline filter all need to be replaced twice a year.

The RO filter has a lifespan of 24 months, so you’ll only need half of that annually.

The post-carbon filter, which lasts 12 months, will need to be replaced once a year.

Drumroll, please… 🥁 Adding up these individual costs, you’re looking at an annual total of $144.83.

But hey, who doesn’t love a good deal? If you opt for the 2-year filter combo, it’ll set you back just $122.32, slashing your annual upkeep to a mere $61.16. Now that’s what I call a steal! 🤑
