The APEC ROES – 50 is one of the top selling reverse osmosis filtration systems (RO) systems on the market today. The system produces 50 gallons of pure drinking water every day, this equates to a little over 2 gallons per hour. This output volume can vary depending on the water pressure and temperature – the lower the pressure and lower the temperature the lower the output and vice versa. The system is supplied with everything that you need to operate the system and change the filters, although some tools will be needed to install the unit (see Ease of Installation below).
There are 5 stages to the filtration system;
Stage 1 – removes sediment including dust and rust. This also helps extend the life of the RO membrane
Stage 2 and 3 – Carbon block filters – remove chlorine, odors, tastes and any discoloration or cloudiness, as well as VOC (volatile organic compounds) and other chemicals from the water
Stage 4 – High rejection TFC RO membrane. This removes a wide range of contaminants including arsenic, bacteria, lead, fluoride, chromium, radium amongst others.
Stage 5 – Coconut Shell Refining Carbon filter —removes any possible residual taste from the water before it enters the storage tank.

Filtration System Design
The ROES – 50 is a filter and holder system. This means that all the filters and the membrane are removed from the filter holder and then a replacement filter is fitted back into the holder and the holder replaced.
The stage 1, 2 and 3 filters, which require replacement at between six and 12 months’ use, depending on the condition of the inflowing water, are loosened with a supplied ‘C’ spanner and unscrewed by hand. The old filter element is removed and replaced with the new filter element, the filter holder is then screwed in and tightened with the ‘C’ spanner.
Stage 4 (the RO membrane) and stage 5 filters elements are replaced at 2 to 3 year intervals, again depending on the quality of the inflowing water.
As with all RO systems, the incoming water is used to flush the RO membrane. This flushing water is often wasted. APEC suggest that the waste water can be used for watering gardens or filling ponds. If you have fish in your pond, you may wish to check the waste water before use as the quantity of contaminants will be typically slightly higher that would normally come out of your faucet.
The amount of water needed to flush the membrane varies depending on the incoming pressure of water, but typically with the APEC ROES – 50, 3 gallons is wasted for every 1 gallon of pure water.
Ease of Installation 4.3/5
The complete APEC ROES – 50 is a compact system that is designed to be installed in a small under counter base unit although it can be installed anywhere there is a convenient water feed line. The whole system is designed to be installed by a do it yourself of average skill levels in about 1 hour with minimal DIY tools that most households will already have. To help with installation all the tubes are color coded depending on where they connect to.
The system is designed to be installed where the water pressure coming into the filtration unit is between 40 to 85 psi. for lower water pressures an alternative system of a pressure boosting pump may be needed.
The installation and user manual is quite detailed but it is worth taking a look at the following videos from APEC before you start as they do show how easy the system is to install.

The filters do not have an indicator to check when they need changing. The best way to check if the filters need changing to test the water occasionally with a TDS meter.

From our APEC ROES – 50 review you can see why it is one of the bestselling RO filter systems in the US. While the filters are a little more difficult to replace than the modular filters on systems such as the Home Master TMAFC Artesian Full Contact Reverse Osmosis Under Counter Water Filtration System the cost of the ROES – 50 system is less than that to the Home Master system. Added to that the waste water produced per gallon of pure water is 3 gallons on the against 4 gallons on the Home Master system (without a permeate pump). The significance of this additional gallon of wasted water may be a factor in the overall running cost of the system over the lifetime of it.
For quality and price and lower than average running costs, the ROES – 50 is a highly recommended RO filter system. Read more on our homepage.
