If you are looking for an under sink reverse osmosis system, the APEC Top Tier Alkaline Mineral pH+ 75 GPD 6-Stage Ultra Safe Reverse Osmosis System is another choice, based on its price, rating, performance and customer reviews.

This system is very similar to APEC ROES-50, but it has 2 major differences. This system can produce up to 75 gallons of pure water every day, while ROES-50 only produces 50 gallons. And it also has a remineralization filter to add safe minerals back, making pure water taste perfect. Of course, it is a little more expensive than the ROES-50, but only with a little extra expense, you can get these 2 great improvements. It is worth having them.

With a remineralization filter, the pure water from RO filter tastes very bland. This is because all the minerals are removed by the RO membrane, but only minerals in water can make water tastes fresh. Therefore, if you like to drink RO water directly, a remineralization filter is an essential part of a RO system. And this system has such a filter, so the RO water from this RO system tastes fresh. And dissolved minerals also balance the pH of RO water, making it alkaline not acidic.

As a 6-stage water filter, the ratio of pure water to waste water is 1:3 – an average level.

And the installation or setup is also pretty easy. It comes with everything you need. You can install it yourself with your basic DIY skills in 1 hour. Plus, a storage tank and a faucet are also included.

Filtration System Design

Each filter has its own housing, which means they don’t influence each other. When you need to replace a filter, you need to remove its housing first, and install the filter and at last recover the housing. It is may be a little messy, because water is still in the housing.

The lifespan of stage 1 to 3 filters is relatively short and you need to replace them every 6 months. These filters are used to pre-filter water, which can protect the RO membrane in stage 4. It is also very easy to replace them. Use a “C” spanner wrench (you can find in the package) to loosen the housing and then unscrew it by your hand. Remove the old filter and fit in a new one. Screw the house back and tighten it with the supplied “C” spanner. Of course, you can grease the housing threads, so it is easy to twist it off next time.

The RO membrane is on the stage 4. It should be replaced every 2 to 3 years, so the stage 5 filter does. Of course, how long they can last depends on the quality of the source water. And this system doesn’t come with an indicator, so a TDS test meter is a must-have item to help you know the water quality.

The stage 6 filter is a remineralization filter which helps make filtered water fresh by adding safe minerals back in the water.

As a 6-stage RO system, it is able to remove up to 99% of bacteria, cysts, chemicals, viruses, organics and more.

Water Efficiency

It is known that RO systems need water to flush the RO membrane or create back pressure, so they will waste water. Waste water is useless, and in most cases, it is sent down the drain. Well, it is not recommended to do that. We can take a good use of the waste water. For example, we can use it to water our garden or we can use it for non-drinking purpose. If you plan to that, you need an additional tube to reach the waste water container.

How much waste water a RO system will produce depends on the water pressure of the feed water. For this system, each gallon of filtered water will result in 3 gallons of waste water. This filtering level is average. However, this system doesn’t come with a permeate pump, so the level is acceptable. If you don’t want to spare so much water, you can buy a permeate pump to raise the water pressure, or you can choose other RO systems  (like Home Master TMAFC-ERP)that come with a permeate pump in the package.

Ease of Installation

Thanks to its compact design, it doesn’t require much space for installation. Therefore, you can install it anywhere you like just if there is a water feed line nearby. Of course, basic space is needed. You also don’t need to hire someone to install it for you, but you can install it yourself with your basic DIY skills. Trust me, and it is not complicated. And this will only take about 1 hour. Plus, color-coded tubes ease the tube connection.

Feed water pressure should be between 40 and 85 psi. If the water pressure is as low as 40 psi, a permeate pump is essential to raise the pressure. If the water pressure is as high as 85 psi, a pressure regulator is needed.

To simplify the installation, there is a user manual to help you quick know how to start. And it also comes with several videos for you to watch.

This system doesn’t have an indicator, so you will guess when you need to change its filters. Actually, you don’t have to. If you have a TDS meter, things become easy. It will help you know the water quality. If there is an obvious drop in quality, it is time to do that.

Although it is compact and doesn’t require much space for installation, spare space for removing the filter housing with the spanner wrench is needed.

FAQs

Question: Does this RO system comes with a pure water faucet?

Answer: Yes, it does. So you don’t need to buy it additionally.

Question: How much space does this system take up under the counter?

Answer: The dimension is 16″w x 5.25″d x 17.5″h and the tank dimensions is 11″ x 11″ x 15″ .

Question: How much water does this RO system use to flush all contaminants?

Answer: The ratio of filtered water to waste water is 1:3. This means it uses 3 gallons of water to flush all contaminants for every 1 gallon of pure water.

Question: Can I add a UV light to it? How much does the UV light filter cost?

Answer: Well, it is not recommended to do that. Actually, you can buy another model, like the ROES-UV75 that comes with a UV light filter.

Question: Can this system raise the pH of pure water?

Answer: Yes, of course. It can raise 1 pH or higher?

Question: Can I use the pure water to feed the dishwasher?

Answer: Yes, of course. It can remove calcium, so it doesn’t cause calcium scaling on the dishes?

Question: Can it be used with an ice-maker?

Answer: Yes, it can. You can install the outlet straight to your ice maker. Or you also can choose to buy an ice-maker kit which can direct another outlet to it.

Verdict

This system has a remineralization filter and its 75 gallons water output per day makes it a great choice, in contrast to ROSE-50. You only need to pay a bit more.

And the APEC Top Tier Alkaline Mineral pH+ 75 GPD 6-Stage Ultra Safe Reverse Osmosis System is not a modular design filter, so it is a little difficult to replace its filters, compared to modular design filters. Anyway, it is also very easy. The water efficiency is average and an additional permeate pump can improve the efficiency.

All in all, thanks to its 6 stages, low maintenance costs, inexpensive replacement filters, and great overall performance, it deserves to try.
