This review features APEC’s highly popular Essence ROES-50 reverse osmosis water filtration system.
We are going to cover all its pros and cons, talk about installation and maintenance requirements + costs, and in the end give you our final verdict of what we think about the unit.
APEC Essence ROES-50
First things first, the APEC ROES-50 uses 5 filter stages to provide clean and great tasting drinking water that’s also ideal for making coffee.
The ROES-50 requires a minimum operating pressure of 40 psi. In case the pressure in your home is below that threshold you have to expect poor results.
The recommended maximum operating pressure is 85 psi. Anything above that is likely to cause damage to the system and increases the chance for leaks.
Maximum total dissolved solids that the system can handle: 2000 ppm – which is a lot!
Recovery rate: 3:1 at optimum efficiency (pretty standard).
As you can already tell from the name, the ROES-50 provides up to 50 gallons of filtered water per day, at least in theory. Due to backpressure and other factors the actual amount that can be produced is lower.
Still, no matter how much water you use for drinking, cooking and to wash your car (just kidding), filtration capacity, water flow and the 4-gallon storage tank should be 100% sufficient even for larger families. FYI: The system will automatically shut off once the tank is full which takes a minimum of 3 hours.
What’s more, according to APEC, the ROES-50 is suited for treating tap AND well water. Plus we like the fact that it’s affordable and noise-free during operation.
Last but not least, the system is backed by a 1-year limited warranty (2 years with product registration), lifetime support from WQA certified specialists, and excellent customer feedback.

As with most RO units, DIY installing the APEC Essence ROES-50 is fairly simple. For one, you get all supplies that are needed for the setup. Secondly, the system uses quick connect fittings and color-coded tubing which makes the whole process a lot easier and faster (also goes for maintenance).
Now, obviously, this is 100% subjective and depends on your previous plumbing experience and also if you have the right tools at hand or can get them from somewhere.
In any case, you can count on APEC’s online installation videos that provide easy-to-follow instructions. Here is part 1 of a 5-part video series:
Both filters and the RO membrane are relatively long lasting, meaning that maintenance requirements are low.
But the system works with housings rather than a modular design. So if you want to replace one of the components you will have to open its housing first. And since water flows through the housing, you would do good to have a bucket at the ready. In other words, things can get a little messy but not too much.
On the upside, the total annual replacement costs are acceptable. Systems that come with modular replacement filters are usually more expensive.
This is how often you will have to change each component as per manufacturer specifications:
As always, you should take this as a rough guideline. How long each filter respectively membrane will last in your home also depends on your water usage and the contamination level of the feed water.
On a side note, all components are industry standard sized so you could buy cheaper aftermarket replacements to save additional cash if you want to.

Here is what we don’t like:
The strengths of the APEC Essence ROES-50 reverse osmosis water filter system is that it’s (A) affordable, (B) low in maintenance, (C) provides enough water that (D) tastes great.
Our verdict for this Amazon bestseller: 4.5 out of 5 stars!
