Regardless of whether you get treated water supply from the municipality or if you use well water, having a filtration system is quite important. Why? Such water contains impurities, chemicals, and bad odors. Also, some people live in rural areas where they don’t have access to water treatment plants. As a result, they need water filter systems to get rid of contaminants in the water.
Here, we will focus on water purification systems that use reverse osmosis to eliminate the contaminants. Particularly, the iSpring RC77 and the APEC Top-Tier ROES-50. Both systems rely on a 5-stage filtration process, and we’ll deeply delve into each to show you how they compare.
Read on to find out about the specifics of each of these water filtration systems.
iSpring RCC7 Overview
Multi-stage filter performance
This model follows a 5-stage filtration performance to give you access to clean and safe drinking water.
Stage I: High capacity .5 micron sediment filter
The water first goes through a high-capacity sediment filter. It gets rid of sand, rust, dust, and other contaminants that aren’t visible to your eye.
Stage II and III: .5 micron activated carbon filter and carbon block
Next, the water moves through the activated carbon and carbon block, whereby chlorine is eliminated. It’s also in these stages where bad tastes and odors, and cloudiness in the water are removed.
Stage IV: 0.0001-micron reverse osmosis membrane
In the fourth filtration stage, your water goes through a reverse osmosis filter, which is quite effective in removing the remaining contaminants. It eliminates up to 99 percent of TDS in the water. After this stage, you have pure water, which gets stored in the filter’s chamber before it proceeds to the final step.
Stage V: post-carbon filter
Finally, the water goes through a post-carbon filter, where bad tastes and odors are removed after it has left the storage tank.
The iSpring RC77 reverse osmosis system is considered quite efficient when it comes to providing clean and safe drinking water. It does, though with minimal wastage, considering it has a wastewater pure water ratio of 2.5:1. Besides, it’s environmentally friendly.
The installation process of the iSpring RC77 is quite easy. If you have basic DIY skills, you should manage to install your system in no time. The unit also comes with an instructions manual, but that might prove problematic for first-time users. But once you get things right, you can install it under your sink seamlessly.
APEC Top-Tier ROES-50 Overview
Let us now have a look at the APEC ROES-50 to see how it compares to the iSpring RC77.
Multi-stage filtration performance
Like the RC77, the APEC ROES-50 also follows a 5-stage filtration process. Here’s what happens in each stage.
Stage I: high-capacity sediment filter
Like its counterpart, the ROES-50 also relies on a high-capacity sediment filter in the first stage. Here, rust, dust, and particles larger than .5 microns get blocked. The difference between the two systems here is that the APEC uses a polypropylene depth filter, while the iSpring uses a polypropylene sediment filter.
Stage II and III: Carbon-based filtration
The ROES-50 also relies on carbon-based filtration in its second and third stages. It contains activated carbon particles, which are laid as a carbon block to remove chlorine and other chemicals from the water. The double-carbon filter also gets rid of foul smells and cloudiness from the water.
Stage IV: 0.0001-micron reverse osmosis filter
The water then goes through a reverse osmosis membrane, whereby dissolved solids and contaminants are removed to up to 99 percent. This stage is the backbone of this filter as it makes your drinking water clean, safe, and tasty.
Stage V: final-brush filter
Lastly, the APEC is fitted with a coconut shell refining, which removes any residual tastes from the storage tank. It also adds some softness to the water. On the other hand, the iSpring uses a granular activated charcoal filter in the final stage, but it serves a similar role.
The APEC qualifies among the most efficient RO water filtration systems with a wastewater pure water ratio of 3:1. You might think this is a lot, but other systems have a larger ratio than that. Therefore, that makes this unit more efficient, plus it’s also kind to the environment.
In case you were worried about the installation process of the APEC ROES-50, you shouldn’t be. This unit comes with all the components that you require to install it. But you’ll need tools such as a screwdriver, a drill, and an adjustable wrench.
You will use your drill to make a hole in the counter to allow you to install the faucet. After that, the rest of the installation process should be quite easy. Besides, the instructions manual is clear enough for a first-timer to understand. With proper installation, you can use your unit for not less than six months before carrying out any maintenance tasks.
Looking at the iSpring RC77 and the APEC ROES-50, you can see they have a lot in common. For starters, they’re both reverse osmosis filtration systems. Second, they rely on a 5-stage water purification process. Also, they fall within the same range. You could pick the model that best suits you of the two. But our overall winner is the iSpring RC77. Why? It has less water wastage, plus it adds some minerals to the water after the purification process.
