Water is one of the few substances that are essential for all human life. We will always need to consume water and for this reason, it is necessary that we are provided a constant, clean supply of it. This is where water filtration systems can be so important. They prevent harmful substances present in tap or municipal water sources (such as arsenic, cadmium or fluoride) from entering our bodies.

Some water filtration systems like this one from APEC use reverse osmosis to filter the water. In this process, the unfiltered water is passed through a semi-permeable membrane that removes the impurities, leaving the water tasting better and healthier.

Five-Stage Filtration System

There are many elements that make up this filtration system and make it efficient and capable enough to do its job. The ROES-50 has a five-stage filtration system built in, which means that the water undergoes five different processes which aim to nullify any and all impurities inside the water. They all fulfill multiple purposes inside the system.

The initial stage consists of a sediment removal filter which serves two things. First, it ensures any dust particles that are as small as five microns do not pass through it. Consequently, it makes sure that impure foreign materials do not travel further and damage the membrane (which is essential for reverse osmosis filtration), thus prolonging the life of the entire system.

The second and third of the system consist of a two layers of carbon blocks. These are 10” filters that work efficiently to remove volatile organic compounds and chemicals that are present in the water improving its odor and taste. Carbon Block filtration usually uses activated carbon that is very absorbent and porous. This allows the impure materials attracted to it to be restrained and the water to pass through.

Stage four in the process introduces the semi-permeable membrane mentioned earlier. This is known as a high rejection TFC (Thin Film Composite) reverse osmosis membrane. This is a very selective layer as it does not allow most contaminants to pass through it including arsenic, chlorine, lead, fluoride, barium, radium, and chromium.

Finally, the last stage of the filtration system composes of a Coconut Shell Refining Carbon filter. This ensures that there is no lingering taste left from the tank, producing delicious tasting water.

System Efficiency, Performance and Convenience

Most aspects of the system contribute to a high-performance filtration. The system promises the removal of 98-99% of contaminants in the water thanks to the complete Essence Reverse Osmosis Filter set that is installed in the system.

It has many features that promise a long life. It can pump an output of up to 10,000 gallons. The filters used are large capacity block filters that can last 6 to 12 months with constant use.

The system is convenient as it does not make loud noises and works entirely on the pressure of the water, subverting the need for a power source/outlet. This also ensures that you save electricity in the long run. The size is also ideal for installation under the sink, but if that is not an option, it can be placed in the basement as well. Thankfully, it has a smooth finish that does not make it unpleasant. The installation is meant to be simple and easy; the manual is accompanied with fittings that connect quickly and tubing which is differentiated in color. Filling the tank is not an issue as it takes less than an hour and stops automatically when filled up.

Customers’ Reviews and Conclusion

Most people who have tried this model have found it more than satisfactory. People notice that there is a significant change in the taste of their water; compared to unfiltered water, it tastes much better. Not only does it affect the water, but any beverages made from the water are also considered pleasing to the drinker.

One of the most notable comments was that there is a great ease in installing this filtration system. Some say it took them as less as thirty minutes to completely install it. Since it may take an additional hour or so to fill the tank, the filtration system is bound to work within two hours. Hence, you will not have to tinker around with the product for a long while before you can get filtered water.

The customer service and manufacturing (made in USA) of the company have often been acclaimed by its users. There have been some notable issues regarding the placement as it does not accommodate over-the-counter facilities, but this has been mitigated by reports from many users that conclude that the system is not very big, so there is always space leftover for the use of that area.

Overall, this “best buy” water filtration system is a multifaceted piece of technology that provides healthy drinking water to its users without any mental strain. Trust in the company image combined with the positive feedback for the product has established this system to be one of the best of its kind. You will not regret purchasing this product as it will give you the best results that you desire.
