APEC Water ROES-PHUV75 Reverse Osmosis System


The ROES-PHUV75 is one of APEC’s high calibre models within its Essence series providing a comprehensive filtration process that guarantees the purest water possible.

The unit is amongst the three versions of the APEC Essence ROES-UV75 model which only differs a little bit in terms of features. The first version is the ROES-UV75 itself with a 6-stage filtration process featuring a UV light filter.

The second version is the ROES-PHUV75-SS with a 7-stage filtration process featuring a PH filter and stainless steel UV light filter.

The third version is a variant of the ROES-PHUV75 which equally has a 7-stage filtration process that features a PH filter and a white UV light filter which is slightly different from the stainless steel UV light filter in the ROES-PHUV75-SS version.

In this review, we look at the second version which is the ROES-PHUV75 model with a stainless steel UV light filter.

Filtration Process

As I mentioned earlier, the APEC Essence ROES-PHUV75 is a comprehensive RO system equipped with 7 filtration stages that deliver super contaminant rejection rates and reliable performance.

The 1st stage of the unit consists of a polypropylene sediment filter which eliminates sand, silt, dust, rust and other particles down to 5 microns.

The 2nd and 3rd stages are the same quality coconut shell carbon block filters which effectively absorb and get rid of almost all the chlorine, chloramines, VOCs and chemicals that lead to unpleasant tastes, odors, colors and cloudiness in the water.

A high rejection TFC RO membrane sits in the 4th stage and it removes all the remaining contaminants down to 0.0001 microns. It gets rid of 99.99% of the total dissolved solids (TDS) in the water and 1000+ contaminants including fluoride, radium, chromium and heavy metals. The filtered water from the TFC membrane is then delivered to the RO storage tank.

5th Stage – UV Light Sterilizer Filter

From the storage tank, the RO water is passed through a 5th stage which consists of a watertight chamber featuring a UV light sterilizer filter.

This stage is what makes ROES-PHUV75 exceptionally effective at ensuring you get purified water that’s completely free of contaminants. The UV light sterilizer contains a powerful UV lamp that emits strong UV light with a wavelength of 253.7 nanometers. 

As the water flows past the lamp, all the harmful microorganisms are exposed to the lethal germicidal UV energy of the emitted UV light.

The germicidal energy effectively attacks and destroys the genetic core (DNA) of the microorganisms stopping their ability to reproduce, and ultimately causing them to die completely.

The best part is that unlike ordinary UV sterilizer filters, this one features a stainless steel interior. It reflects the UV light evenly throughout the chamber hence facilitating the highest UV coverage possible.

Therefore, no microorganism gets to escape the lethal germicidal energy from the UV light. The filter will kill up to 99.99% of all the harmful microorganisms in the RO water from bacteria to viruses to cysts and other microbial pathogens.

In addition, the filter uses an all-natural process. It doesn’t change the taste or composition of the water in any way.

6th Stage Post-Carbon Filter  

From the UV light filter, the water passes through the 6th stage where it’s further refined by an advanced coconut shell carbon filter that clears any possible residual chlorine and taste from the tank.

7th Stage Alkaline Filter

The final stage in the ROES-PHUV75 RO system is APEC’s calcium mineral cartridge which is an alkaline re-mineralizing filter and it adds calcium carbonate into the RO water thereby raising its pH level. It increases the pH value by 1 to 1.5.

The outcome of combining these 7 highly-effective RO filtration stages is total contaminant-free purified water with much-improved alkalinity and great taste.

Filtration Capacity and Efficiency

The production rate of the ROES-PHUV75 is 75 gallons per day which is the same as the APEC ROES-PH75 and makes it an ideal choice for small to large families.

A 4-gallon storage tank is included with the unit and it can hold up to 3.2 gallons of water which is also a good capacity that should suit the needs of most households.

The unit releases 3 gallons of wastewater for every gallon of pure water it delivers, so it falls a little short with regards to filtration efficiency. But again this tells you how thorough the filtration process is despite the amount of water wasted being relatively high.

Installation and Maintenance

Installing the ROES-PHUV75 may not pose a lot of difficulties with some basic DIY skills. It comes quick connection fittings and all the tubing are colored to enable fast and easy installation and maintenance.

There’s a detailed manual to guide you throughout and you can even refer to several videos on YouTube to help you out if you get stuck.

The filters are really durable and this is one of the things that set apart APEC’s RO systems from the rest. The prefilters and the 7th stage UV filter will last up to 12 months while the membrane, post-carbon filter, and the alkaline filter can go for up to 2 to 4 years.

To sum it all, the APEC ROES-PHUV75 is a system designed to deal with highly contaminated water especially where there are concerns about possible microbial contamination. It will effectively eliminate all contaminants in your water and give it a great, natural taste.
