5. BACOENG 5-Stage Ultra-Filtration Under-Sink RO System

BACOENG 5-Stage Ultra-Filtration Under-Sink

Pure water production per day: 35 gallons

At the bottom of the list, we have the BACOENG 5-Stage Ultra-Filtration Under-Sink. Don’t buy this one just because of its price, because that will not be worth it. Sure, it is cheap and easy to install and maintain, but it’s just not a good product.

It’s not good at filtering water. It will not always filter out the alkaline and hose rubber thus resulting in water that doesn’t taste very well. It also has a poor water production output per day, at only 35 gallons. That’s very low, and half of what other systems can produce in a day.

The design is rather poor, and it doesn’t feel durable at all. We’ve heard from long-term users of this product, that it has a rather short life expectancy. Some had theirs break within a few months, and others within just 1½ years.

This model is simply a big disappointment and not one that we recommend anyone to buy. Don’t try and save yourself a few bucks by picking this one, because it will not be a good long-term investment. You’ll end up with an unreliable filtration system that will produce low amounts of water, that won’t even taste very well. Not recommended.


  • Easy to install and maintain


  • Mediocre tasting water. Doesn’t always filter out the alkaline and hose rubber.
  • Low pure water production (35 GPD).
  • Not the best life expectancy.
  • Not very durable.
  • Poor design.
  • Not very reliable.

What Is Reverse Osmosis?

reverse osmosis process


The process is done through water purification technology that passes water through a semipermeable membrane to purify it. The membrane used in reverse osmosis is small enough that water molecules can pass through but other materials that have larger molecules will stay behind. The semipermeable membrane has been designed in a way that allows clean and safe water to separate from larger molecules that could harm your health and body.

The process also involves the amount of water pressure applied; the use of pressure is to overtake osmotic pressure. Reverse osmosis is used to eliminate numerous kinds of molecules and ions from the water including harmful bacteria. The process is used in not only residential settings but also industrial settings.

The normal process of osmosis is centered around the movement of water from an area that has a low solute concentration to an area of higher concentration of solute through a semipermeable membrane. The need to reduce free system energy triggers the pure solvent’s movement and balances the concentration of solutes on the two sides of the membrane. This generates osmotic pressure. Reverse osmosis is then the application of external energy on that reverse the natural flow of the solvent.

While they may seem fundamentally the same, filtration and reverse osmosis have key differences. Filtration involves the constant straining of water to remove solvent molecules. It stops huge molecules from passing through despite the pressure applied or the solvent concentration. Reverse osmosis, on the other hand, uses factors associated with diffusion. Pressure and flow rate prevent contaminants from passing through the membrane. Reverse osmosis is great at removing many chemicals and unwanted minerals such as salt from seawater.

Benefits of Having a Reverse Osmosis System

pure and clean waterReverse osmosis is most highly praised for ridding your drinking water of unwanted contaminants. There’s always the danger of drinking water becoming contaminated with pollutants and many people across the country are worried as cases of contaminated water hit headlines. The water you drink at home has a lot more in it than just pure H2O. While not all the minerals and chemicals in your water are bad for you, there is still the risk of overexposure to the minerals and chemicals that are bad for you. Reverse osmosis completely eliminates your drinking water of these potentially harmful presences including barium, radium, fluoride, selenium, chromium, nitrites and nitrates, copper, arsenic, lead, and total dissolved solids.

If hard water is your problem then water softeners seem like the go-to solution. They eliminate the hard minerals in water but they are unable to purify your water. Water softeners are great for the water you use for laundry, cleaning, and dishes. It’s a fine drinking water as well but not everyone enjoys the taste of it. The taste of soft water comes from the sodium molecules that have replaced the hard minerals. Plus, water softeners don’t eliminate any total dissolved solids which can also impact the taste of the water. Reverse osmosis systems totally eliminate any sodium leftover from your water softeners. The systems are actually recommended with the use of soft water as they are more efficient that way.

The water produced by reverse osmosis is also better for cooking. Any impurities that may be in your home’s water will affect the way the food you cook tastes. Water is used in a variety of ways in the cooking process. Whether you’re making homemade bread, boiling water for pasta, or making, you’ll need water to start with. While boiling water will kill a lot of bacteria present, it can do nothing about the presence of minerals or chemicals like chlorine. These factors can add unwanted flavors to your food and in some cases even discolor it. Some restaurants have completely switched over to reverse osmosis for cooking.

Another benefit that may seem meaningless to many is that reverse osmosis water freezes into clear ice cubes. You may have noticed in your past attempts to freeze water that they ice cubes may appear to be cloudy and slightly white. This appearance is due to the impurities found in your water. Not only does the clear ice cubes that RO water produces look nice in your drink they also last longer. Regular ice cubes that are cloudy are softer as well as melt faster. The ice cubes made from reverse osmosis water will last longer in your drink allowing it to stay cool and preventing it from becoming watered down.

The advantages of having RO water outweigh the disadvantages. Poor water can attribute to too many physical health problems (immune deficiency, high blood pressure, gastrointestinal issues, and cancer) to risk having it unpurified in your home. Luckily, the option to have clean water is not only more readily available than ever but also more affordable.

How Reverse Osmosis Has Been Applied

The discovery of RO has not only revolutionized the water you drink at home but how different industries use water. It has become one of the world’s most useful technological discoveries. Besides providing safe drinking water at a cost-effective price, it also has been used in many other areas.

While this process is used in thousands of households around the world, its use for drinking water is not only limited to residential drinking water. Companies and businesses are beginning to switch to RO water to provide for their employees. Others are bottling RO water to sell. The United States military also uses the process for drinking purposes and is used by thousands of soldiers.

Wastewater is put to great use with the process of RO. Collected rainwater can be collected and put through the process to feed irrigation systems and industrial cooling. Large power plants can use reverse osmosis water to get rid of minerals in their boiler which tends to build up and cause long-term issues. Using pure water in it prevents the minerals from leaving deposits that can potentially lead to corrosion to the machinery.

The food industry also is switching their water source over to reverse osmosis. It’s used in the production of juices as well as tomato sauce as the water used for these cannot be heated. In the dairy industry, it’s also used in the production of whey protein and in concentrations of milk. It’s also used in the removal of acetic acid, smoke, and alcohol in the wine industry. It’s also used to get rid of the excess water that is found in syrups, especially water found in maple sap. It removes up to 80% of the water from the sap and the leftover is made into maple syrup.

a car washReverse osmosis is also being used more and more in the car wash industry. They use the process to get rid of hard water, which is known to cause spotting on cars if not treated. This is because it removes the hard minerals in the water. This cuts the cost in all aspects of car washes because many customers don’t ask for their cars to be dried.

The process is also being used among reef aquarium keepers. Tap water that has been used in aquariums for years has dissolved nitrogen compounds, chlorine, phosphates, heavy metals, and chloramines. These elements are not ideal for the seawater mix that is required for reef aquariums.

Reverse osmosis is becoming an extremely common element of our day-to-day life and is continuing to advance to benefit people around the world. While looking for the best reverse osmosis water filter, there are a few factors to consider before committing yourself to one.

How To Buy The Best Reverse Osmosis System

Water contamination is a highly talked about topic these past few years and everyone is looking for a solution to solve the problem. Reverse osmosis provides the solution to this issue but there are a few things to consider when looking for a system.

Size: The size of the system you choose is important because it can determine where you store it as well as how many gallons it can filter per day. A typical system typically runs with water pressure that ranges from 40 to 100 psi and usually is able to generate about 10 to 75 gallons per day. The system’s actual production is at a rate that is 50% to 75% of the system’s gallon per day rating. It’s important to note that gallons per day is not just dependent on the size of the system but also whether or not hot water is being used with it, what contaminants are in the water, and that gallon per day ratings are determined by tests under optimal conditions.

Type: There are only really two types of reverse osmosis systems: residential and commercial. Systems for commercial use typically have a higher water pressure than those found in a residential setting. The increase in water pressure is to meet the demand of the large number of people that will be drinking the water. The pressure rate of commercial systems is usually around 100 to 250 PSIG.

Much like residential systems, commercial one’s performance depends upon the type of membrane used as well as the quality of the source water. The major difference between commercial and residential RO systems is that commercial systems cost more due to the addition of several features. These features include monitors, pumps, fuel gauges, and electrical supplies. While residential reverse osmosis systems can be installed underneath the sink, commercial units are usually mounted on the wall, secured to the floor, or installed within a frame.

Source Water: Source water is the type of water going into your reverse osmosis system. The two common types of source water in the United States is well water and city water. The type of source water you choose largely determines the type of reverse osmosis system you choose.

Those who live in more urban areas are likely to use city water from a water treatment plant located nearby. The water has already been through a type of treatment so it’s less contaminated; it’s not completely contaminant-free so filtration is still suggested. An entry-level or basic reverse osmosis system gives a good enough filtration to fully give you clean and crisp water.

Well water is found in suburban areas where private wells are used. The microorganisms, bacteria, and other contaminants are found in high quantities in this type of source water. UV lights found in more advanced RO systems are the best at eliminating these organisms and giving the freshest and most sterile water.

Water Pressure: Another absolutely crucial factor in choosing a water filtration setup for your home is considering water pressure. High pressure is needed in an RO system so that water can be properly pushed out through the membrane and leave the contamination behind. Houses in the city should be able to meet the minimum required pressure of nearly all RO system. For those who have a psi less than 40, you will need a booster pump or a model that has a booster pump that comes with it.

Filtration Quality: The technology used in different RO systems determine the filtration quality. Besides the main semipermeable membrane, there are pre-filters as well as post filters that help in eliminating elements and determining the effectiveness of the whole system. Many brands claim that their product removes 99% of contaminants from the water. To test the filtration quality of your reverse osmosis system, you can use a TDS meter.

A TDS (total dissolved solids) meter measures the water filtered through your system against the source water. It shouldn’t be the sole method as you may have a system that has alkaline remineralization will have a higher reading as compared to those who don’t.

An alternative method to the TDS meter is to look up their NSF and WQA certifications. Both of these organizations are nonprofit and you can find details on their certification and the criteria of their test done on the system.

To triple check the quality of filtration, you check the quality of the source water in your area via the Consumer Confidence Reports of your community. Knowing how contaminated your water is can help you choose the reverse osmosis system that’s right for you.

Flow Rate: The flow rate of your system depends on quite a lot of factors. These factors depend upon water temperature and water pressure. The flow rate is what determines the gallons per day that your system produces. As stated earlier it’s more than just the size that determines the gallons per day. While the range of gallons per day is 10 to 75 gallons, most systems produce 50 gallons per day and, in most cases, the system produces about 10% to 20% less than advertised. If you’re using a system for a large family then a system that only produces 50 gallons per day will not be enough.

Budget: When searching for the best RO setup, you need to consider the cost at initial purchase as well as maintenance costs down the road. The initial cost is pretty straightforward and you should be able to find a decent system for $100. Maintenance costs include the cost of replacement filters, faulty parts replacement, and any other repairs you might need to do. There will be cases where replacing the whole system is the better option than just spending money on maintenance.

Ease of Use: Day-to-day use of your RO system should be easy to use, but you want to ensure that it’s also easy to use when you want to make sure it’s in working order. You want to check how often the filter should be changed as well as how complicated the cleaning process is before you commit to one to buy. If you know you’re not the type of person who will change their filter quite regularly then go for a system that doesn’t require a filter change for a while.

Waste Created: A downside to the process of RO is that it creates a lot of water waste. The majority of systems only are able to recover about 5% to 15% of the water that’s filtered. The waste is often necessary to get the clean drinking water you desire but there are systems out there that are dedicated to reducing water waste. Much like other appliances in your home, such as your clothes washer and dishwasher, they recycle the water waste for other purposes. These types of systems are best for those who are environmentally conscious who want clean drinking water and do not mind using the water waste other aspects of water in the home.

Other Factors: The number of stages and the arrangement of the filtration system are also worthwhile features to take into consideration. Most reverse osmosis systems have around three to four stages with some having up to five. Obviously, the more stages they have the better filtration, purification, and sterilization your water will undergo but the cost will be more. The arrangement of filters are the processes that the water goes through before passing through the membrane. It’s important to make sure that your system has at least three filters: one to filter out sediment and two to filter out carbon blocks.

Tips When You’re About To Buy

  1. Make sure the brand you’re buying has good customer support. There are a lot of issues that may arise when you purchase and own a reverse osmosis system. Customer support is important not just to commercial buyers of RO systems but they’re important for residential buyers as well. Whether it comes when you’re installing the system by yourself and something goes amiss or one of the parts is faulty, you will run into a problem some time along the road. When these problems happen, you might not know how to fix it and that’s where customer support comes into the picture. You want the brand you bought your system from to have a helpful and friendly customer service to help with your issues. Some companies only have their support available at limited times which can be a problem if an issue happens unexpectedly. It’s important to find a company that can help you whenever you need it. As you continue your search for the best reverse osmosis water filter for you, be sure to inquiry how often the company sends out notices for regular checks and services.
  2. Grow your knowledge of the types of contaminants that can be found in your water. Learning the elements that are in your water is extremely important in not only determining the RO system for you but evaluating your health. Sometimes you can smell, see, or taste when something is wrong with your water but there are many unseen pollutants in the water you’re drinking. Hard metals are found in the untreated city and well water. Hard water can lead to marks on your dishes, the feeling of film left on your hands after washing, and possible health issues. There are more than twenty possible contaminants that you can find in your water. You must know what’s in them so you can properly buy a system that can tackle your issues effectively. Knowing that features like UV lights can help properly sterilize your water can help you decide whether or not that’s a feature you wish to have.
  3. Be sure to note if it needs to bear any weather conditions and what those conditions are. A variety of reverse osmosis systems can be placed outside but not all of them are built to stand the weather. There are some like those featured in the RoWave series that Global Water Solution produces that are manufactured with an outer shell to protect it from the wear and tear of the weather. There are also models of RO systems out there that are solar powered. Those interested in these types of RO systems should ensure that the conditions the system are in are sunny and that you don’t experience a lot of rain or thunderstorms in your area. When looking at RO systems that are housed outside, be sure to look for a system that is durable and can withstand all types of weather.
  4. Be sure you’re not ignoring the quality of your carbon block filters. All elements of your filtration system are deeply important but you want to be sure that you purchase a system that only one sediment filter and two solid carbon block filters. Some companies will try to give you two sediment filters and skimp on the extra carbon filter. This will compromise the water quality you get as well as the durability of the system’s membrane. That being said, there are two types of carbon filters you can have in your system. One is GAC filter and the other is a carbon block filter. The granular activated carbon filter is more likely to leak, which can cause a block in your RO system and cause chlorine to leak which will wear out your membrane over time. Carbon block filters tend to last longer and they do not experience any leakage.
  5. Read the fine print of long-term warranties. Many companies that offer reverse osmosis systems also offer long-term warranties that seem too good to be true and they often are. While some warranties are up front and tell you they’re just applicable to certain parts, others advertise themselves like it’s for the whole system. Ones that offer warranties for 5 years or more are often not what they seem. Many of these warranties are hiding conditions. Those that offer just a year or so are more legitimate. Make sure that you read the fine print on your warranty before committing to one system so that you’re fully prepared for what you’re getting into.


Clean water is not a luxury, it’s a necessity that everyone should have. Unfortunately, it’s not the reality for many but it can be with the right filtration system. The choices that homeowners and companies have to filter their water is endless. There are so many products and companies out there that promise to give you clean water that not all of their promises can possibly be true. When hunting for a water filtration device, be sure to check out reverse osmosis system reviews to get a good grasp on what the system has to offer as well as the pros and cons of the product.

The types of RO systems to choose from are numerous. There are those that come with all of the bells and whistles attached and can eliminate just about anything from your water but they come at a steep price. There are others that are more affordable that still has fancy features but maybe not as many stages of filtration. Then there are the basic RO systems which can do the job and are well within your budget. You may even have the option of buying one that’s more affordable now and then upgrading it with better features later.

All of the reverse osmosis systems listed in this review have the potential to be the best osmosis system for you. Putting into consideration the price, effectiveness of the product, and durability of the product, the best RO system that could fit anyone’s needs is the Home Master TMHP HydroPerfection Undersink. Its whopping nine stages of filtration just cannot be topped by another. The UV lights it uses to sterilize the water is cutting edge and gives you the cleanest, crispest, freshest water you can get. Its results taste even better than bottled water. Though the price may seem a little steep at purchase, the maintenance costs are low and the customer support is always on your side.

For those who cannot just get over the purchasing cost, the best budget-friendly from the group is the APEC Top Tier ROES-50. While there are cheaper ones available, this is the RO system that really gives you the bang for your buck. It doesn’t have as many filtration stages as the Home Master or the cutting-edge technology of UV light but it is highly reliable. It has three stages that are solely dedicated to filtering out thousands of contaminants. It also comes with a 30-day money back guarantee and a year warranty. You can also buy upgrades whenever you want which really make this RO system worth the purchase.

While some obvious benefits come from the process of RO, there are still critics that think the method is too extreme. Some scientists say that reverse osmosis gets drinking water too clean. While it does strip the water of contaminants and harmful minerals, it also eliminates minerals that are helpful to our bodies. The counter to that is that you can get those minerals from other sources of food and supplements, but many people around the world don’t have a well-balanced diet to get these minerals from food alone. It’s important to research every aspect of reverse osmosis to determine whether it’s the right step for you in drinking cleaner water.

The future of reverse osmosis looks bright as more and more people are switching over to its use. It’s already been used for over fifty years and is the method of choice for many who are looking to purify their water. With the knowledge scientist have gained with reverse osmosis, a few technologies are being introduced into the water purification world. The main two methods include forward osmosis and capacitive deionization. The primary applications for forward osmosis include wastewater treatment and seawater desalting.
