iSpring RCC7AK RO System [Alkaline Remineralization]

The iSpring RCC7AK is an upgraded version of the RCC7 model with the addition of a nice extra filter. It can filter out all types of contaminants and enrich the water in the same process giving you a healthier, natural-tasting, clean drinking water.

Excellent Filtration Process

The RCC7AK features multi-layered filtration process designed around 6 very efficient filtration stages specially tailored to progressively remove all types of contaminants and improve the water quality.

The first three stages are pre-filters consisting of polypropylene sediment filter in the 1st stage, GAC filter in the 2nd stage and a carbon block filter in the 3rd stage.

These three filters trap all the sediments and particles that are larger than 5 microns and more importantly removes chlorine, chloramines and other chemicals present in the water.

The fourth stage where the magic happens sits a quality RO membrane which eliminates all the remaining contaminants down to 0.0001 microns leaving behind only pure water.

A fine GAC filter takes the fifth stage and where the water from the RO tank is further polished to remove any residual contaminants from the tank.

Restoration of Lost Minerals

After going through the initial 5-stage RO filtration process, the RCC7AK includes a 6th stage which consists of an alkaline remineralization filter.

The standard 5 stages produce clean, pure water with all the contaminants removed as well as the few helpful minerals present in the water.

This 6th stage is a big plus as the alkaline filter restores the healthy minerals lost due to the RO process. The AK filter features red mineral stones which add back calcium and other essential minerals such as magnesium and potassium.

The filter also has a calcite portion that helps raise the pH levels of the RO water hence creating a much natural alkaline balance in the water.

Therefore, you not only get the benefit of drinking clean, purified water but you are also assured of getting some healthy minerals as well and a better, more natural taste.

RO water is so pure and as such it often tastes unnatural, but with this alkaline filter in place, your water will certainly taste much better.

Furthermore, the filter is made up of only natural mineral stones that serve as the filtration media hence your body will have no problem absorbing the restored minerals directly.

Filtration Capacity

The filtration capacity of RO membrane of this iSpring RCC7AK model is also quite decent for an under-sink residential RO system.

It’s capable of producing up to 75 gallons of filtered water a day which is sufficient to handle the water needs of small to medium-sized families whether it’s drinking or cooking.

Moreover, the system is relatively efficient as for each gallon of pure water produced, it wastes only 2 gallons which is really a mean feat for most filtration systems.

Installation and Maintenance

Featuring quick fittings, a cabinet fitted bracket and a clear, well-organized manual and videos, installing the RCC7AK is quite easy, especially if you have some little DIY skills.

All the parts you need including the pressurized tank, faucet, drain saddle, feed water adapter, tank valve and tubings are provided alongside the filters, membrane and the RO frame itself.

The system will easily fit under any standard kitchen sink and the overall construction is quite solid. The filters are durable too with the first three pre-filters requiring replacing just twice a year and the two post-filters requiring changing once a year.

The membrane will last 2 to 3 years based on the quality of your source water. Noise won’t also be a major problem like in other systems. The unit runs smoothly producing the least sound possible. 

All in all, the iSpring RCC7AK is a well-designed RO system with an effective 6-stage filtration process that eliminates all kinds of contaminants from the water and replenishes it with essential, natural minerals.

It’s definitely a win-win investment for anyone looking for an affordable system that can deliver a more natural tasting and healthier filtered water.

iSpring RCC7AK-UV 7-Stage Reverse Osmosis System

The iSpring RCC7AK-UV is yet another top-notch model within the iSpring RCC7 series. It’s the variation of the iSpring RCC7AK model offering the same great RO system that features a remineralization filter but with the addition of a UV light filter. 

iSpring RCC7AK-UV is a deluxe multi-layered reverse osmosis system that provides optimal protection against more than 1,000 different types of contaminants including arsenic, asbestos, chlorine, hormones, fluoride, lead, mercury, sodium, bacteria, giardia, viruses and more.

The RO system consists of 7 processing stages, the first 6 stages work similarly to the previous system RCC7AK, the 7th stage is an 11W UV bulb as an additional protection layer that against the variety of microorganism that past the RO filter.

Filtration Process

The RCC7AK-UV comes equipped with 7 filtration stages which makes it one of the most comprehensive RO systems from iSpring and one that guarantees the best water quality possible.

The initial 5 stages consist of the standard iSpring’s 3 pre-filters we’ve seen in the other models and they remove all large contaminants down to 5 microns and chemicals particularly chlorine and chloramines.

They are followed by the 0.0001-micron RO membrane that removes up to 99% of all the remaining contaminants. The fifth stage is a finer GAC filter which gives the RO water the final polishing as it leaves the RO tank.

After passing through these initial 5 stages, the RCC7AK-UV model incorporates two more stages comprising of an alkaline remineralization filter and a UV sterilization filter.

Sixth Stage – Alkaline Filter

The 6th stage of the RCC7AK-UV uses an alkaline remineralization filter which is made up of red mineral stones that restore the healthy minerals removed from the RO water by the initial 5 stages. It adds back calcium, magnesium, potassium, and sodium.

The filter also has a calcite portion which helps raise the pH level of the RO water to natural alkaline balance giving a better and more natural taste. This is essential as the RO filtration process reduces the pH value of the water making it tastes slightly acidic.

Seventh Stage – UV Sterilization Filter

The final stage in this RCC7AK-UV system features a UV sterilization filter that offers an additional level of protection from possible microorganism contamination.

The filter uses a powerful 11W UV lamp which emits UV light as the water passes through it. The UV light kills 99.99% of harmful organic microorganisms that might seep past the RO filters including bacteria, protozoan cysts and viruses.

To ensure great efficiency, the unit comes with a smart flow sensor switch too which turns off the UV light once the water is not flowing through it thereby saving power. The UV lamp also comes in a protective stainless steel housing to ensure its durability.

Filtration Capacity

The RO membrane of the RCC7AK-UV can deliver a maximum of 75 gallons per day. The capacity might vary though based on your source water pressure and temperature but it’s able to meet the needs of most small to medium-sized families.

The system, however, wastes around 3 gallons of water for every one gallon of clean water it produces. Considering that most of the other iSpring’s model has an average ratio of 2:1, this one will slightly waste more water unless you install a booster pump alongside it.

Installation and Maintenance

As with the other iSpring models in our list, the RCC7AK is not that hard to install yourself if you have basic DIY skills. Everything you need to set it up is provided and the instruction manual is user-friendly with pictures and illustrations that make it easier to understand and follow. The whole unit is compact and will nicely fit under any standard kitchen sink.

Overall, the quality, performance, and features of this RO system are really commendable. By combining both the alkaline and the UV lamp filter means you are always assured of clean, healthy water that has a much better and natural taste throughout.

It’s a system we would highly recommend for anyone wanting a unit that offers more than just the standard RO filtration process.

Pros

  • Removes more than 1000 different contaminants
  • Alkaline filter restores healthy minerals and raises pH
  • UV filter to help kill harmful microorganisms in the water
  • Flow sensor switch helps keeps power cost low
  • Up to 75 gallons of clean water output per day
  • Relatively easy to install and operates quietly
  • Comes with a 3-year limited warranty plus a 1-year money-back guarantee

Cons

iSpring RCC7 Reverse Osmosis System Review

Our first top pick is the iSpring RCC7 RO system. This is one of the best-selling RO products from iSpring.

iSpring RCC7 reverse osmosis system is unequaled in performance, quality, and durability. This RO system has a 5-stage filtration that removes over 1000+ different kinds of contaminants and it features 75 GPD.

It’s simple and affordable but a very reliable and efficient system that’s more than capable of removing all kinds of contaminants in the water.

Filtration Process and Stages

The RCC7 features an effective 5-stage RO filtration process which does so well to produce very clean and pure final water that’s safer and healthier to drink.

The first batch of filters in the system are three carbon-based pre-filters that make up the first three stages.

The first stage is the sediment filter which is a high capacity polypropylene filter that removes all sediments and silt in the water down to 5 microns.

The second stage is made up of a 5-micron granular activated carbon (GAC) filter which is quite effective at trapping large contaminants and chemicals like chlorine and chloramines as well as removing microorganisms present in water.

All the particles, microorganisms and chlorine that leaked through the second stage GAC filter are trapped by the CTO carbon filter in the third stage.

These three pre-filters are amongst the best you will find in the market. They perform so well with regards to eliminating most of the contaminants, chemicals, and microorganisms present in the water which allows the RO membrane to function at its maximum efficiency.

The membrane itself it’s a thin film composite filter that makes up the fourth stage of this iSpring’s RCC7 filtration system.

It’s very capable of removing contaminants down to 0.0001 microns which is so small to allow only water molecules to squeeze through while stopping up to 99.99% of up to 1,000 different contaminants.

Virtually nothing else will be able to pass through. It will completely remove all the harmful contaminants that often appear in well and municipal water including chlorine, dissolved solids, arsenic, bacteria, and viruses.

The final stage consists of a fine GAC post-filter which does the final polishing of the water by removing any other TDS or contaminants in the water from the RO tank before it’s delivered to the faucet.

The five stages of the systems progressively remove contaminants, cleaning and purifying the water to improve its quality and taste. 

Filtration Capacity

The membrane of the RCC7 also has a high throughput which big thumps up. It’s capable of delivering up to 75 gallons of purified water every day which is sufficient capacity for nearly any family size even large families.

For every gallon of purified water produced, the system wastes around 3 gallons although it may vary depending on the quality and pressure and of your feed water. However, this average ratio you will find in most standard RO systems.

Installation and Maintenance

The system comes with quick-fitting connectors and everything that you need including all the parts from the storage tank to the faucet as well as all the mounting hardware and clear, well-organised instructions.

So, installation is pretty much straightforward if you are a very handy person or have some basic DIY skills. The system requires very little maintenance too as there are no moving parts.

The pre-filters have a service life of 6 months before requiring replacement while the post-carbon filter needs to be replaced every year. The membrane, on the other hand, will go for up to 2 to 3 years before requiring replacement.

Furthermore, the first stage filter (sediment filter) has a clear-see through housing which facilitates an easy way to inspect the condition of the filter and know when it’s time to change it before a problem occurs.

The only setback we noted about this system is that the O-rings are somewhat thin and look a bit flimsy. Even so, it’s not really a deal-breaker as it can last long enough before you can change it for much better quality.

All the other components and parts are of great quality. The tank is made of steel and the construction of the main RO unit is sturdy which makes it very durable. You will also not hear any sound as the system is in operation. It’s super quiet.

Pros

  • An effective 5-stage filtration process
  • Removes up to 99.99% of all contaminants
  • Can deliver 75 gallons of pure water per day
  • Has quick-connect fittings for easy DIY installation
  • See-through first stage filter housing for easy inspection
  • The filters and membrane have a decent service life
  • Comes with a 1-year warranty and lifetime support

Cons

  • O-ring is quite thin and somewhat flimsy
  • The wastewater ratio is relatively high

iSpring RCC7P 5-Stage Reverse Osmosis System Review

iSpring RCC7P reverse osmosis system is an extended version of the RCC7 with an electric booster pump that ensures reliable, consistent performance regardless of pressure variations. This RO system is ideal for low-pressure water, the booster pump allows the system to achieve tank fill up to 50% faster and 50% less water waste.

If you live in an area where your typical residential water pressure is low, say around 40psi or lower, then this iSpring RCC7P might just be the ideal choice for you.

It’s a high-performance system designed with an inbuilt pump that boosts the feed water pressure high enough to allow the system to perform much effectively.

Filtration Process

Like the RCC7 model, the iSpring RCC7P utilizes a 5-stage RO filtration process which ensures reliable and efficient water purification results.

The three first stages consist of three 5-micron pre-filters that include a polypropylene sediment filter followed by a carbon KDF (GAC) filter and then a carbon block (CTO) filter.

The first two filters trap all sediments, large contaminants, and microorganisms that are bigger than 5 microns including chlorine, chloramines and other chemicals.

Smaller contaminants, chlorine, and microorganisms that pass through the second stage are further removed by the carbon block filter in the third stage.

The fourth stage is a high rejection RO membrane which gets rids of all remaining contaminants that are as small as 0.0001 microns.

It has a rejection rate of 99.99% hence can eliminate more than a thousand harmful pollutants including arsenic, viruses, bacteria, chemicals, lead, pesticides, chlorine, and fluoride.

The final stage is the fine GAC filter that provides the final polishing. It removes any possible residual contaminant and odor that may have accumulated in the RO tank delivering clean and safe purified water to the faucet.

Inbuilt Booster Pump

Now the most commendable thing about this iSpring RCC7P model and what makes it really perform so well is the fact that it’s equipped with an inbuilt booster pump.

The RO filtration process requires high feed pressure so as to force all the impurities out of your water and when it’s low, the system will not be efficient. This is where this booster pump comes into play.

It’s designed to raise the inlet/feed water pressure going into the system from as low as 30 psi to about 70 to 80 psi which is an ideal level that optimizes the performance of the system from the first stage to the final one thereby facilitating more efficient filtering.

Furthermore, the pump features multiple sensors which help keep track of the pressure and turn on the pump as soon as the source water pressure falls below around 40 psi.

The sensors also automatically turn off the pump when the ideal pressure is obtained hence preventing any chances of overheating or other potential damages. Therefore, you are assured of consistent performance regardless of pressure variations.

Filtration Capacity

The RCC7P like its counterpart above utilizes a high capacity RO membrane that’s capable of producing 75 gallons of water per day which is large enough to handle the needs of most medium to large families.

Moreover, the booster pump helps increase the water production speed of the system allowing it to achieve almost 50% faster tank fill rate compared to its competitors.

Boosting the water pressure also has the effect of minimizing wastewater production as the pump forces more water through the filters there reducing the wastewater production to up to 50% which is quite commendable.

Installation and Maintenance

In terms of installation, the unit is designed for DIY installation with color-coded tubings and a push to connect fittings. It’s a pretty simple process that may not require the assistance of a professional if you some little technical skills.

The user manual is clear and well-written, and all the necessary parts and tools required for installation are included plus a video should you need visual instructions.

You will need to change the pre-filters after every 6 months while the post-carbon filter can last up to a year before needing to be replaced and the RO membrane can go for at least 2 years.

Both the pump and the system are quiet during operation hence you can expect no disturbance at all. They produce very little noise which you can hardly hear over normal kitchen activity.

In general, there’s no notable setback in this iSpring RO system that can cause any alarm. It’s a reliable unit that will deliver great performance especially in situations where the feed water pressure is below 40 psi. All the parts are of good quality and certified by FDA and WQA.

Pros

  • Optimum RO filtration performance through 5 stages
  • Booster pump effectively raises water pressure to ideal levels
  • Has a high pure water production rate with fairly less wastewater
  • Easy to install with all the necessary tools included
  • Both the pump and RO unit operate quietly
  • Ideal for use in areas with a feed water pressure of less 40psi
  • Backed by a 1-year warranty with lifetime support

Cons

  • The supply water valve and O-rings are not of the best quality
  • Requires a power source which may limit your installation options

iSpring RCB3P Reverse Osmosis System Review [Commercial Grade]

iSpring RCB3P reverse osmosis system combines three high-efficiency 100gpd RO membranes with a booster pump that produces up to 300 gallons of filtered water per day (300GPD). This is a great choice for commercial applications.

The iSpring RCB3P is amongst the top commercial-grade RO systems on the market. This flexible and convenient system is specifically designed for producing the purest water at high capacity making it a perfect model for commercial applications like in restaurants, labs, and industrial or hospital settings.

Filtration Process

The iSpring RCB3P uses a 5-stage filtration process that effectively removes all kinds of contaminants and impurities from your water supply. Stage one is a polypropylene sediment filter which traps all particle larger than 5 microns.

Stage two consists of a granular activated carbon (GAC) filter while in stage three there’s an activated carbon block filter. These two help remove chlorine, chloramine, cloudiness, odors, VOCs and other chemicals hence improving the taste of the water.

Stage four is made up of a triple membrane design consisting of three highly efficient RO membranes.

This unique combination of top quality RO membranes ensures optimal performance in removing all kinds of contaminants in the water from heavy metals, viruses, bacteria, toxins, hardness, and a long list of many other impurities.

The fifth stage is a carbon post-filter and this eliminates any residual tastes, odors, and contaminants from the RO tank.

Now the best part about this unit is that while most other systems feature standard 10” filters, this one uses oversized 20” pre-filters.

They remove twice as many contaminants as the standard filters with the same amount of water. This makes the system highly effective and ideal for heavy use in commercial environments without having to replace the filters frequently.

Filtration Capacity

As we mentioned earlier, the RCB3P is equipped with three high-efficiency membranes each producing 100 gallons of purified water per day. Together they give you up to 300 gallons of water per day which makes it a really great option for commercial applications.

300 gallons is a large amount of clean filtered water and it will cater to most large demand needs. It’s perfect for restaurants, small offices, labs, and even salons.

However, it doesn’t come with an RO storage tank which it will require for it to work efficiently. It will need a large pressurized storage tank but it’s compatible with most of the options available on the market, so it’s not something to worry about much.

The system comes with a booster pump which not only increases the feed water pressure to optimal levels but also boosts the production of purified water. It’s capable of raising the pressure up to 80 psi while it can work with feed water pressures as low as 25 psi.

By increasing the pressure to optimal levels, the booster pump also maximizes the efficiency of the membranes hence resulting in a fairly decent pure to drain water ratio.

For every gallon of water produced, the unit will discharge two gallons of wastewater which is a pretty fair ratio compared to most other commercial-grade systems out there.

Installation and Maintenance

The installation of the RCB3P won’t present much challenge as the system comes with all the tools necessary to set it up including the first set of filters.

The only thing you will need is the pressurized RO storage tank and the delivery pump for the output line as the system doesn’t provide adequate pressure.

It comes with a free-standing frame which allows you to set it virtually anywhere you want. It keeps everything nice and clean.

The downside though is that it will take a little more space than other standard RO systems. It’s a heavy-duty system made for commercial settings.

As for maintenance, there’s very little to worry about. The system is designed to automatically flush the membranes every now and then, so no back-washing or manual flushing is required.

The filters and the three membranes last more the ones you will find in standard RO systems as they are oversized 20” filters. The system is all equipped with a pressure gauge to help you quickly monitor the pressure changes and know when the filters need changing.

If you are after the best RO system for commercial use whether it’s in a restaurant, office, lab or salon, the iSpring RCB3P is certainly a perfect choice. It’s capable of producing a large amount of filtered water at a faster rate and the filters are highly durable.
