APEC Water Essence ROES PH75 Reverse Osmosis System


The second spot in our top APEC essence series RO systems is the ROES-PH75 model. This unit is quite identical to the ROES-50 above, but APEC has made two major updates.

The ROES-PH75 comes with an increased water production capacity and an additional remineralization stage which are big improvements that greatly boost its overall performance.

Filtration Process

With the addition of a remineralization filter, the ROES-PH75 offers 6 stages of filtration which includes the same standard 5 stages of the APEC ROES-50.

At the 1st stage is a polypropylene sediment pre-filter which traps all particles larger than 5 microns including silt, dust, rust, and sand particles that might accumulate and clog the other pre-filters and RO membrane.

The 2nd and 3rd stages make use of the super-efficient activated carbon block filters made from coconut shell. These filters together absorb and remove 99.99% of chlorine and chloramines in the water.

They as well remove bad tastes, odors, organic contaminants, VOCs and other common chemicals like pesticides and herbicides thereby improving the smell and taste of the water.

At the heart of the ROES-PH75 system is the 0.0001-micron TFC RO membrane which filters out 99.9% of all the possible contaminants remaining in the water from total dissolved solids (TDS) to microorganisms and other impurities like lead, arsenic, fluoride, radium, and chromium leaving only pure water to pass through.

The 5th stage applies an activated carbon filter also made from coconut shell which gives the filtered water a finishing touch by removing any residual tastes and odors picked up from the RO tank.

6th Stage – Alkaline Filter

The filtered water from the 5th stage is finally passed through the last stage which comprises a calcium mineral cartridge that adds high-purity calcium carbonate into the RO water. 

The calcium carbonate effectively neutralizes the acidity of the filtered water and increases the pH level by about 1 to 1.5 resulting in a more balanced alkaline water.

The pH level of the final water will, however, vary based on the initial pH levels of the feed water and its composition. Nonetheless, with the alkaline filter in place, you are guaranteed to get purified alkaline water that tastes much better than plain RO water.

Filtration Capacity and Efficiency

Besides the addition of the alkaline filter, the RO membrane of the ROES-PH75 is an upgrade from that of the ROES-50 as it offers a higher water output.

It can deliver up to 75 gallons per day at 60 psi pressure which is enough to meet the needs of small to large families that desire a high water production rate.

The storage tank can hold 3.2 gallons of water which is a good capacity that will help keep your water supply constant for most parts.

Like the ROES-50, the APEC ROES-PH75 expels 3 gallons of wastewater for each gallon of clean water produced which is not the best ratio out there but it does ensure a high rejection rate and performance compared to systems with 1:1 or 1:2 ratio.

Installation and Maintenance

When it comes to installing this unit, it’s not overly complicated as it uses quick connect fittings and clear instruction manual. Therefore, if you are quite a handy person and follow the instruction properly, you will have no difficulty setting it up within a few hours.

Maintaining the system won’t also pose many challenges because you only need to replace the filters which are durable. The stage 1, 2 and 3 filters last 6 to 12 months.

Both the RO membrane and the post-carbon filter can last 2 to 4 years while the sixth filter can be replaced every 4 to 6 years.

All in all, although the wastewater produced is a little on the high end, the APEC ROES-PH75 is a great upgrade from the ROES-50 if you want improved water pH and higher output.

Pros

  • Removes all possible contaminants in the water
  • Alkaline filter helps raise the pH level and improves the taste
  • High water production rate at 75 gallons of pure water per day
  • Designed for easy DIY installation and low maintenance
  • Comes with 1-year limited warranty and filters are long-lasting

Cons

  • Wastewater to pure water ratio of 3:1 which is just above average
  • Slightly slow filling as it takes about an hour to fill the tank once empty

Installation Guide

This video shows you step-to-step how to install the APEC Water Essence series Reverse Osmosis System.

How much space does it take if I install it at under the counter?

The system dimension is 16″w x 5.25″d x 17.5″h and the tank dimension is 11″ x 11″ x 15″, hence, you will need a clearance of at least 16.5″ w x 16.5″ d x 18″ h to install the system at under the counter.

Can I add a UV light filter to this system?

Yes, you can, you can purchase the UV filter that comes along with the APEC ROES-UV75 RO system.

Can I buy the system without the faucet and storage tank?

Yes, you can buy the optimal system, please contact the manufacturer for more details.

Can I lay down the tank if there is not enough room for it?

Yes, you can lay the tank down, but you may need a base the keep it stable.
