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.

iSpring RCS5T Reverse Osmosis System Review [500 GPD]

iSpring RCS5T reverse osmosis system is a high capacity tankless commercial grade reverse osmosis system. The RO system’s patented dual-flow membrane produces a rate of 500 gallons per day of RO filtered water with 1:1 waste to a pure water ratio.

iSpring RCS5T is designed purposely for those looking for a system that can supply purified drinking water on demand.

It’s a high-capacity tankless RO water filter system with an on-demand output ability which makes it a great choice for large families, small restaurants, coffee shops, and offices. 

Filtration Process

The RCS5T offers 5 stages of filtration with the first stage being a polypropylene sediment filter which removes debris down to 5 microns. It has a see-through housing that allows you to easily see if it’s blocked and requires replacement.

The next cartridge is a granular activated carbon (GAC) filter which traps chlorine particles, chloramines, and other pollutants like phenol and mineral oils.

The third stage consists of a carbon block filter which further removes all residual chlorine, tastes, odors as well as chloramines and microorganisms.

The fourth stage is one high-quality dual-flow RO membrane that removes contaminants down to 0.0001 microns which virtually eliminates 99% of all contaminants and pollutants common in the city or well water.

The last stage in the system is the post-carbon filter which takes care of any residual chlorine, chemicals or taste impurities and odors from the RO tank.

Tankless Operation

While it has a very effective RO filtration process, what makes this iSpring RCS5T system stand out is that it’s equipped with dual-flow membrane and booster pump, a combination which allows it to produce purified water on demand without requiring a storage tank.

This ability to work without the need for a tank makes the RCS5T an ideal choice for small commercial purposes as well as for households as it’s a great space-saving option.

In addition, the pre-installed booster pump does well to raise the water pressure going into the RO system which helps boost its performance and production rate.

The system can work with feed water pressure that’s as low as 25 psi and a maximum psi of 95 to 100, so it will work efficiently and effectively despite the pressure of the source water.

If your feed water pressure is quite low, you will find this booster pump to be a very useful addition plus there’s a nice built-in pressure gauge to allow you easily monitor the pressure.

Filtration Capacity

With a capacity to produce 500 gallons of filtered water per day (500 GPD) under ideal conditions, this iSpring RCS5T model is more than capable of meeting the daily demands of most large households and small offices with around 10 to 20 people.

The capacity is large enough to allow you even use the system for small commercial purposes like in a small restaurant, coffee shop or store and you will hardly notice any minor variations in the water production.

The best part is that you can pair the system with a pressurized storage tank if you desire to have reserve capacity for a steady and continuous supply.

A storage tank will be essential in case of very high usage situations, especially for commercial applications. You will need a delivery pump too as the output pressure of the clean water is about 10 to 15 psi on average.

Besides the high capacity, another major highlight of this iSpring RO system is the fact that it offers one of the most balanced pure water to wastewater ratio.

The dual-flow membrane ensures consistent output flow with a 1:1 pure to wastewater ratio which is pretty exceptional for such a high capacity system.

It will produce much less wastewater compared to other similar systems on the market that often have a pure to wastewater ratio of 1:3.

Installation and Maintenance

Installing the RCS5T is a breeze. Like the other iSpring’s systems above, this one is also designed for DIY installation and it comes complete with everything you need to set it up including a free-standing metal frame.

The installation manual is easy to understand and categorically explains every step accompanied by pictures in addition to the direct instructions.

Maintaining the unit is also simple. In fact, the system is designed to flush automatically to ensure the membrane is clean and works efficiently. No need to manually flush it.

All it’s required of you is changing the filter cartridges which is every 6 to 12 months for the carbon filters depending on usage and 2 to 3 years for the membrane. Furthermore, the booster pump produces very minimal noise thereby it won’t cause any disturbances.

The only setback is that it requires a power source for the booster pump which somewhat limits your installation options. Moreover, due to the large capacity, the power levels might be somewhat high, but that’s a tradeoff considering that it delivers a lot of purified water.

Generally, if you own a small restaurant, business or need a reliable tankless RO system for large residential use, then this iSpring RCS5T is a perfect choice. It will certainly not disappoint.
