APEC Top Tier 5-Stage RO System – How Does It Work?

Most Reverse Osmosis Water Filtration systems make use of a 4-stage filtration system.

The first stage is called the pre-filter and removes any impurities that could damage the rest of the filters. The second is the RO membrane where the actual catharsis happens. The third is the post-filter (usually a carbon filter) responsible for removing the remaining contaminants that lead to foul odors or bad tastes.

The APEC does things a bit differently and more thoroughly by moving the carbon filter to in between the pre-sediment filter and the RO membrane and splitting it into two distinct filters. This is done partly to improve the system’s lifespan and to more thoroughly clean up the particles responsible for taste and smell.

The 5-Stage System


The first stage of the process makes use of a Premium Sediment Filter. These filters remove most of the sand, dust, metal, and rust particles that could damage the rest of the system. Without this filter, your system will have a much shorter lifespan.


The second Premium Carbon filter block filters out all the remaining substances to ensure the that the water is odor free, tastes fine, and has no residual chemicals or impurities.


The fifth and final stage is a filter that you might not have seen elsewhere before. A Refining Coconut Carbon Filter. This filter is there to ensure the best tasting and clearest of drinking water.


The first of two Premium Carbon filter blocks removes most impurities associated with odors and bad taste. This includes chlorines, VOC’s, and other chemicals. After this stage, the water will already look much clearer.


Only now we get to the actual refinement aqua systems. The APEC makes use of a High Rejection RO Membrane which they claim is the only one on the market capable of removing 99% of contaminants. These include fluoride, arsenic, and lead amongst others.

This is how you install the system under you sink.

So, What’s Our Impression?

Although it is always hard to judge by pure taste and looks, the water that comes out of this system tastes, looks and smells crystal clear. However, APEC is a popular and well-recognized brand and many other parties have seemed to confirm their claims that it’s the most thorough filtration system on the market and the only one capable of 99.99% elimination of impurities.

The biggest downside is probably that the system looks very dated. You will definitely want to hide it away from any eyes. Then again, purification systems have never been known for their beauty, which Brondell H2O+ brand offers. It is stylish RO system that circles the water and gives superior clarification of aqua at the fair price.

The use of the ROES-50 purifying distill is also a welcome addition. This is a very well-received and reputable workhorse of the osmose industry and we are happy to see it used in any product.
