Water production

The water production of any system depends on feed water pressure and temperature. APEC ROES-50 produces 50 gallons per day at 60 psi. This amount of production may vary due to the feed water pressure and temperature. But this amount of water is enough for even larger families.

If you want even more water output with identical features, APEC RO-90 will be the best fit for you.

Its storage tank comes with a capacity of 4 gallons. Again, the duration to fill the tank depends on pressure. Usually, this storage tank can be filled within 2-3 hours. Hence why with this system, it is very unlikely that you will ever have a shortage of purified water. You don’t have to keep an eye on it, it has an automatic shut-off valve that will not allow the system to operate once full, minimizing water wastage.


Efficiency is one of the most important factors to consider before choosing the Reverse osmosis system.

The efficiency of RO water filters is measured with the wastewater ratio. The less the wastewater ratio is, the more efficient the system is. The system with a larger ratio costs you a lot indirectly in the long run, plus it is just bad for the environment to waste water.

APEC ROES-50 has a ratio of 3:1. In simple words, it will flush 3 gallons of water to produce a gallon of purified water. This ratio is not the best on the market but it is very good, as many competitors of this Water filter system have a ratio between 6:1 and even up to as high as 24:1.

APEC ROES-50 does not accumulate any real additional water costs that you have to pay indirectly. With this efficiency, it is considered a relatively inexpensive water system in the long run.

Filtration system

APEC ROES-50 handles the purification process efficiently with 5 stages filtration system. Water of every kind can be treated efficiently, can remove 99% of harmful contaminants from your water.

Its filtration process is based around the same system used by many other RO water filters. Firstly all the solids, dust, and rust particles are removed from the water.

In the 2nd and 3rd stage, filters remove the chlorine and chemicals from water which are harmful and cause odors and bad taste in water. The 4th stage enhanced the purification by removing all the possible hazardous contaminants like lead, radium & bacteria from water. At the final stage, the filtration process eliminates residual wastes from water.

The replacement of filters depends on how often you use the RO water filter. The feed water quality and pressure. Water temperature also affects the lifespan of filters. It is recommended by the manufacturer to replace the stage1 – stage 3 filters after every 6 months. Stage 4 & 5 filters can last for 2-4 years. You can get the replacement filters at a reasonable price.

If you are filtering heavily dust contaminated water such as ground or well water then you should monitor the first filter closely as they can clog quickly.
