Best Reverse Osmosis Reviews

—————

1. iSpring RCC7AK – Best Alkaline Reverse Osmosis System

—————

iSpring RCC7AK reverse osmosis system takes the top spot on our list as it strikes a perfect balance between price and quality. It’s moderately priced without compromising on quality and performance.

There are three major things that makes it stand out from the other mid-range models available in the market, that is, the filtration system, capacity and convenience.

This is a 6 stage filtration system and apart from the basic 5 filtration stages, the model includes a re-mineralization filter which forms the 6th stage of the filtration process.

The five main filtration stages perform a thorough cleansing with a rejection rate of up to 99%. They will remove over 1,000 contaminants to the highest degree including minerals both helpful and harmful.

As you may know, after the basic RO filtration process, the purified water tend to taste a bit acidic which is a little different from natural pure water. This is because all the dissolved minerals that are helpful and provide flavor have been removed.

This is where the 6 stage re-mineralization filter comes in handy.  The filter is made of half calcite and half-red mineral stone which restores the mineral balance of the water as well as its natural alkalinity.

It adds back magnesium, calcium and other healthy mineral that were stripped away. This will help improve how the water tastes as compared to systems that don’t feature a re-mineralization filter. It’s an important addition not just for the taste. It also help neutralize the pH level.  

The capacity of the RCC7AK is also quite impressive. The unit can deliver up to 75 gallons of purified water per day which is ideal for bigger families.

Another wonderful feature is the fact that the 1st stage housing is transparent. It will allow you to monitor the sediment filter so that you can change it on time.

Installing the whole system under a standard kitchen sink is easy too plus the unit comes with color coordinated tubings and push to connect fittings that simplify the whole process. It will fit under almost any sink.

The waste is quite low. For each gallon of purified water produced, only two gallons of water are wasted. The ratio usually ranges from 1:1 to 1:2, so this is good compared to other systems.

In general, this a great product, one that will supply your family with pure, healthy drinking water for many years. It’s a quality reverse osmosis system and that works very well and can deliver years of service.

Pros

  • Very effective six-stage filter system
  • Low waste water ration
  • Remineralizes the water
  • It will fit under any standard kitchen sink
  • Offers very ample capacity
  • Reasonably priced

Cons

  • The 12 month filter life is a bit short
  • Water may not be as alkaline as natural pure water

2. Home Master TMAFC Artesian – Best Full-Contact Reverse Osmosis System

—————

Next comes the Home Master TMAFC Artesian system which really offers a savvy, efficient and affordable way of keeping your drinking water clean and healthy at all times.

The Artesian Full Contact modular filters avoid some of the most common problems of a traditional
reverse osmosis filter system.

For one, instead of changing only an internal filter, the Home Master system has complete cartridges that simply pop into place. It’s easy to change them because you don’t have to deal with prying open a housing sealed shut by crusty hard water buildup.

Secondly, it’s more sanitary because both the filter and the filter housing are changed at the same time. It doesn’t give contaminants a chance to build up.

This unit has been designed to produce highly pure water using an effective 7-stage filtration system with a capability of removing up to 99% of all possible contaminants in the water.

It filters the water in 7 distinct stages to maximize the quality and purity of the water that you get at your tap every time. It even has a very efficient catalytic carbon filtration media which is capable of removing close to 100% of all chloramines and notorious heavy metals present in the water.

Like the iSpring RCC7AK, this one features a re-mineralization filter too which will help in balancing the water’s pH level as well as help in restoring the essential minerals like calcium and magnesium.

Delivering up to 50 gallons of purified water per day, the TMAFC does offer sufficient capacity to cater even for larger families. The 50 gallons per day is sufficient for most household chores and drinking as well.

The water wastage ration is average at 3 to 4 gallons for each gallon of purified water. It’s only slightly higher than that of the iSpring RCC7AK, and the best part is that if you use the permeate pump, the ratio drops to 1:1.5 or 1:2.

It’s easy to change the filters without tools and you only need to do it once a year. In addition, if you are a handy person, installation is relatively straightforward and there are even videos from the manufacturer on YouTube to guide you through the process.

Same to its counterpart the iSpring RCC7AK above, there is nothing much to worry about this Home Master model. In fact it comes with a 5 year limited warranty on its parts which coupled up with its efficient 7-stage filtration process, arguably makes it one of the best reverse osmosis to invest in. It’s worth every single penny.

Pros

  • Effective, all-round filtration process
  • Restores the essential minerals and water pH level
  • Sufficient flow rate to cater for the needs of small to large families
  • Easily changeable filters
  • Simple to install with a bit of DIY skills
  • Comes with a very accommodating 5 year warranty

Cons

  • Feed tubing is a bit short
  • The pumps makes some noise

3. APEC Essence ROES-50 – Best 50 GPD Reverse Osmosis System

—————

In the third spot on our list is the APEC Essence ROES-50 reverse osmosis system. This is one of the best APEC water filtration systems out there offering a great price-performance ratio.  It’s a high quality, budget choice that can give you nothing but good value for your money.

There are 5 filtration stages which combine to remove 99% of all the contaminants to deliver clean, pure, filtered drinking water.  Amongst them is the extruded carbon blocks which helps eliminate chlorine and any possible residual taste or odor.

You will have to get a remineralizing/pH balancing filter separately or remineralize the purified water in other ways because this unit does not feature one. The good thing though is that the filters are long lasting.

The three main filters last for 6 months, while the other two can go 2 to 3 years before you can replace them. Plus the package includes a spare set of filters.

Like the Home Master TMAFC above, this unit can deliver up to 50 gallons of clean water per day which is sufficient capacity for cooking, drinking and even washing.

The waste water produced is not that high. The system’s water filtration efficiency is around 3 to 1, so it waste 3 gallons of water to produce one gallon of pure water. It’s not the best ratio, but it is average compared with other models.

Installation is rather simple with average DIY skill level and as long you adhere to the instructions. The tank and the system are compact hence it should fit easily in most kitchen cabinets.

The only setback is the fact that it doesn’t feature a re-mineralization filter. You will have to get it separately to balance the pH of the water and add essential minerals removed by the RO process.

Another thing would be that there is no indicator to let you know when the filters need changing. So, you will probably have to test the water exiting and entering the system with a TDS meter.

Other than that, this is a budget friendly unit that will provide clean and clear drinking water with almost all impurities removed. It offers great value if you don’t have much to spare in your budget.

Pros

  • Efficient filtration system that can remove 99% of contaminants
  • Long-lasting filters (RO membrane lasts between 2 to 3 years)
  • Delivers 50 gallons of clean water per day
  • Simple to install and maintain
  • Compact size that fit in most kitchen cabinets

Cons

  • Does not feature reminaralization filter to add back minerals
  • No indicator to let you know when to change the filter

4. APEC Essence ROES-PH75 – Best 75 GPD PH Reverse Osmosis System

—————

The ROES-PH75 is another super quality RO system from APEC.  It’s much similar to the ROES-50, but with two big improvements which although add a little amount to the purchase price, still makes this one of the few advanced water filtering systems that you can get a decent price.

It uses a very reliable 6 stage filtration process to purify your water. Stage 1 to 4 consists of four filters, polypropylene sediment filter, double carbon blocks, and high rejection RFC RO membrane.

These filters work together to get rid of all harmful contamination in the water with 99% efficiency. From dust to common chemicals to bacteria’s, TDS and chromium, all contaminants are removed from stage 1 to 4.

The 5th stage features a coconut shell carbin11on-TCR filter which eliminates any possible residual taste arising from the tank. At the end, there’s a remineralization filter which is an addition that misses in the ROES-50 model above.

With this filter in place, you will get a fresher tasting mineral water that’s healthy for you and your family. The filter will add the safe minerals back to the purified water and help raise the pH to balance the water alkalinity.

The capacity of the system is an area that has also received a big boost compared to the ROES-50. The APEC essence ROES-PH75 offers you a whopping 75 gallons of purified water per day which is very suitable for families with bigger needs. 

The amount of water required to produce 1 gallon of pure water is 3 gallons. Like I mentioned above, this a pretty much average ratio you will find in most small to medium-sized RO systems. However, if you wish to spare much water, then you install a permeate pump alongside this system.

The installation might be a little challenging if you have no basic DIY skills but if you are handy, it shouldn’t be a problem. It’s a compact system that’s designed to fit in small under counter spaces.

The longevity of the filters is one thing that you will also appreciate when using this model. Although the first three filters have a lifespan of six month, the RO membrane together with the carbon filter in stage 5 will last for 2 to 3 years. The neutralizer filter on the other hand can go for 4 to 6 years.

However, replacing the filters might prove a little challenging and messy. They have to be removed from the filter housing which also contains water inside and there is no indicator also to show when to change them. You must also tighten the connections pretty well due to possibility of leakages.

To sum it all, the addition of the remineralization stage and a high capacity makes this OPEC ROES-PH75 model a great alternative to the ROES-50. Despite the slight price difference, you are guaranteed high purity and taste of water with a high output rate. It’s an investment that you will definitely be proud of.

Pros

  • 6-stage filtration process for maximum effectiveness
  • Remineralization filter adds minerals and raises pH
  • High output rate at 75 gallons each day
  • RO membrane has a longer life span, between 2 to 3 years
  • Relatively easy to set up and maintain
  • Comes with a 2 year warranty

Cons

  • The filters in housing might be difficult to replace
  • There’s possibility of leaks if connections are not strongly tightened

5. Express Water RO5DX Reverse Osmosis System

—————

The Express RO5DX presents a simple way to filter your tap water at home. It’s a straightforward RO system with a decent filtration performance at an affordable price which makes it ideal option for those working with a very small budget.

Like most other systems, the RO5DX utilizes a 5-stage filtration process to deliver safe and clean drinking water. The filters from stage one to four removes all possible contaminants in the water source.

The 5th stage consists of a post-activated carbon filter which takes care of odors and residual taste. However, there’s no remineralization filter, so you will have to buy it separately.

The unit can produce around 50 gallons of pure water a day which is standard for most RO units. Combined with the 4 gallon storage tank, you will have sufficient clean drinking water every time.

The best part is that this Express model features an emergency leak stop detector. When the tank is filled, it automatically shuts off the system to stop the water flow into the unit. Hence, there no danger of water overflowing from the storage tank.

For every gallon of pure water produced, three gallons are wasted, so it’s fairly efficient and will save you some bit money in the long run.

The unit comes with complete push-in quick connect fittings that are color-coded to let you know what hose goes where. Plus, the instruction booklet is detailed with diagrams and colored illustrations to aid you.

Therefore, it’s quite easy to install and to replace the filters too if you have basic plumbing skills. However, the filters are not long lasting like in the other units above. The pre-filters need replacement twice a year while the RO membrane and the post carbon filter need to be replaced one a year.

In general, aside from replacing the filters frequently and the fact that it does not feature a remineralization filter, everything else is perfect and well built.

If you have a tight budget but still want a unit that’s capable of delivering clean drinking water without any issues, then the Express RO5DX might be a good option for you.

Pros

  • Impressive 5-stage filtration process
  • Comes with extra filters for easy replacement
  • Automatically shuts off water flow when the storage tank is filled
  • Delivers 0.8 gallons of purified water every minute
  • Easy to set up and use
  • Highly competitive price

Cons

  • Does not include a reminieralization filter
  • Filters are replaced frequently compared to other models

6. iSpring RCC7AK-UV – Best Alkaline & UV Reverse Osmosis System

—————

The iSpring RCC7AK-UV is a more advanced and high-quality variation of the RCC7AK which tops our list. This unit offers a more comprehensive filtration process compared to the rest of the units that we have reviewed.

The RCCAK-UV utilizes 7 different stages of filtration which deliver great-testing bottled-water quality. In addition to the five common filters, the unit features an alkaline mineralization filter that restore the natural alkaline balance and healthy minerals to produce a more natural tasting water.

Another major addition is the Ultraviolet (UV light) filter which is one of the major highlights of this iSpring RO system. The filter will effectively eliminate the small percentage of microorganisms, viruses and bacteria that could possibly remain in the water source after the RO process.

The UV lights automatically turns on once it detects the water flow, but it keep in mind that it requires a 110V power plug.

Nonetheless, the combination of these powerful filters and considering that the RO filter removes contaminants down to 0.0001 microns, this unit is no doubt capable of dealing even with the foulest of waters. It’s ideal option for filtering both well and tap water.

With a capacity to deliver 75 gallons of purified water a day, the iSpring RCC7AK-UV is another unit aside from the APEC ROES-PH75 that’s ideal for larger families with high water demand. You are guaranteed clean water at all times.

The unit has an efficiency ratio of 3:1, considering that it delivers 75 gallons of water, it’s a pretty efficient filtering system. It would take around one hour to install the unit if you have basic DIY skills. It comes with everything your will need to set it up.

While it’s hard to point any drawbacks in this iSpring system, nothing is perfect and one area of concern is that the filters’ lifespan is relatively short compared to competing systems.

That’s the only major thing you will have to worry about. In general, this is an efficient all-round system that can deal with almost all kinds of contaminants. It’s an excellent choice if you use a natural well as your home water source but will also work perfectly for tap water.

Pros

  • High capacity, producing up to 75 gallons of pure water a day
  • Remineralization filter adds minerals and raises pH level
  • Ultraviolet filter (UV) kills viruses, bacteria, and microorganisms
  • The package includes a water leakage alarm
  • Ideal for both tap and well water
  • Fairly easy to install and maintain

Cons

  • The filter life is somewhat short than similar systems
  • Instruction manual is poorly written

7. APEC RO-90 – Best 90 GPD Reverse Osmosis System

—————

Quality and quantity is what describes best this APEC RO-90 reverse osmosis system. It’s almost identical to the ROES-50 above, but what makes it stand out is one major difference. It purifies water at a very high speed, nearly twice as fast as an average home RO system.

The filtration process involves the standard 5 stages you see in most RO systems but the filters are high capacity filters. They are super-efficient and will get rid of up 99% of all contaminants in the water.

The double carbon block filters have been uniquely designed to offer a large surface area to maximize contact time. This design enables the system to achieve the optimum possible chemicals and chlorine removal in the water.

However, the major highlight of this unit is not the filtration system but rather its massive capacity. If there’s a very high water usage in your home, then this might just be the unit for you.

The APEC RO-90 is capable of delivering a whopping 90 gallons of water per day which is the highest of any RO system on our list. This super capacity makes it an ideal choice for larger families and households.

The amount of waste water is 3 gallons per every gallon of purified water. It’s a lot but it gets covered by the flow rate plus you can install a pump to reduce the amount of waste water.

Unlike most similar units, the filters of this OPEC model will serve you efficiently for longer before you can replace them. The filters in the first to third stage need to be changed only once year while those of most other units will go for only about six months.

RO membrane and the stage five filter can last 3 to 5 years before you can change them. They will out-live filters of other similar models by double fold.

Setting up the system won’t present any problem as long as you are able to follow the instruction manual and all the fittings you will need are included in the package.

If there’s any notable issue to point out would probably be the membrane filter housing design. It can be quite difficult to open and access the filter, but it’s a problem affecting only a few of the filters not the entire line.

To sum it all, the APEC RO-90 is an RO system made for those whose water usage is higher than average. While the filtration process consists of the standard 5 stages, the unit performs thorough cleaning and guarantees a fast pace flow rate every time. It’s an investment that won’t disappoint.

Pros

  • Reliable 5-stage filtration process
  • Long lasting filters
  • Offers one of the highest flow rates at 90 gallons per day
  • Installation and maintenance is quite easy

Cons

  • Opening the RO membrane filter house is a bit difficult
  • No remineralization filter

8. Ukoke UWFS01W Reverse Osmosis System

—————

The Ukoke UWFS01W is another great budget choice we included on our list. It comes at a very competitive price but does manage to offer a high level of performance that you would find in most medium level units.

The filtration system of the Ukoke UWFS01W will remove all kinds of impurities in your tap water while retaining the beneficial minerals in the water. The three pre-filters combined with the RO filter will remove all contaminants down to 0.0001 microns.

In the fifth stage theirs is a post carbon filter which takes care of odor and residual taste. The process is completed by an alkaline remineralization filter which restores the essential minerals as well as the natural pH balance of the water. The end results is fresh, clean, great tasting water.

The unit can deliver 75 gallons of water per day. That’s more than what you would find in most affordable units like this. It’s sufficient production speed to cater for the needs of those that use large quantities of water or have large family.

In terms of water waste efficiency, the UWFS01W is not the best on our list neither is it the worse. Like most of the other units here, it has a waste water to clean water ration of 3:1, so for every gallon of purified water produced, 3 gallons are wasted.

The whole system is designed to comfortably fit under a cabinet and putting it together is fairly simple. The manufacturer provides a step-by-step installation guide video that takes you through the whole installation process. You won’t a problem installing on your own.

However, the installation manual is poorly written. It’s not that clear and has very few diagrams and illustrations. You will have to get the video demo just to ensure you get everything correctly.

Other than that, the Ukoke UWFS01W is budget-friendly unit with ample capacity and efficient filtration process. It will deliver great results without you having to dig deep into your.

Pros

  • 6-stage filtration system featuring remineralization filter
  • Will get rid of all contaminants in your water
  • Offers ample flow rate at 75 gallons a day
  • Putting it together is easy

9. Whirlpool WHER25 Reverse Osmosis System

—————

If your water usage is not that high or you are living alone but still want to ensure your drinking water is properly purified, then the Whirlpool WHER25 will most probably be a perfect choice for you. It’s a really affordable unit, but still quite efficient at cleaning the water.

Despite being a 3-stage filtration system, the unit performs really well. It has the mandatory three filters needed to remove numerous unhealthy contaminants such as chemicals, sediments, arsenic, lead, dissolved solids, chlorine odour and taste and many more.  

It offers a very decent performance for a unit of its size and price. It will definitely deliver pure, fresh water. You will not get large quantities of water from this unit either, but if your water demand is on the lower side, then you have nothing much to worry about.

The unit can produce around 14 gallons a day which is just enough to cater for the daily drinking and cooking needs of a family of 4. However, in comparison to its water wastage ratio which is 3 gallons of waste water for one gallon of pure water, this Whirlpool is isn’t that much efficient when it comes to water wastage.

You can easily change the filters without any hassles or mess. No need of opening anything, it just needs a quarter turn and you have access to the cartridges for replacement.

The pre and post filters need to be changed every 6 months while the membrane should be changed after every 2 years. That’s a pretty decent life span for such an affordable unit. Plus it comes with a built-in filter change indicator that will prompt you when the filters need replacement.

The Whirlpool WHER25 comes ready for installation with DIY instruction manual to guide you through the whole process. The manufacturer also provides lifetime technical support, so should you have any difficulties while setting it up, you can seek their assistance.

10. Aquasure AS-PR75A-BN Reverse Osmosis System

—————

Closing our list is the Aquasure AS-PR75A-BN, a four stage RO system that offers great performance and quality at a competitive price. This is another wonderful choice for those with a tight budget and want to enjoy clean drinking water at all times.

The four-stage filtration process of the unit consists of 5-micron sediment and extruded carbon block filters which form the stage one and two. A 0.0001 micron RO membrane and coconut shell carbon filter form the stage 3 and four of the process.

Therefore, while it may not have a remineralization filter, this unit will eliminate almost all contaminants and give you a refreshing, clean drinking water.

It has the capacity to deliver 75 gallons of pure water per day which is above many other average models on the market.  It will produce enough clean, pure water for the entire family whether large or small.  

The unit wastes around 3 gallons to produce one gallon of purified water which is a bit high, but unlike the Whirlpool WHER25 above, this ratio is covered by the high production rate of 75 gallons per day.

The filters have a good life span too and changing them is easy as you don’t have to take the whole unit apart. Stage 1 and 2 filters last 9 to 12 months while the 3rd and 4th stage filters are to be changed once every 2 years.

The unit has a quick-twist, quick connection design which makes the whole installation process effortless. You won’t have any problems there. This twist and lock design ensures a secure lock every time. It help prevent leaks from loose tightening or cracks caused by over tightening.

BUYERS’ GUIDE

(How To Find Out Your Best Reverse Osmosis System)

—————

Reverse osmosis provides a very effective solution to purifying water, but like any other device that you invest your hard-earned cash on, you want to make sure you choose the best system for your home. With this in mind, here are some key factors that you should consider when purchasing a reverse osmosis system.

Source Water

The first thing you want to consider before you proceed to purchasing a reverse osmosis system is the type of source water that will go into the system. The two most common water sources are well water and municipally treated water or city water.

The type of water source you use will largely determine the type of unit you choose. If you use city water which has undergone treatment, then the water is relatively free of bacteria and chemicals.

It might also contain some level of inorganic dissolved contaminants, so it’s not completely contaminant free. In this case, a basic or entry level reverse osmosis system can do a great job. It will give sufficient filtration to give you fresh, clean water.

If your source is well water, then there’s potential for chemicals and harmful pathogens. Therefore, you will need a unit with a powerful filtration system like the iSpring RCC7AK-UV.

An advanced reverse osmosis system such as the iSpring RCC7AK-UV above is the best because they are able to eliminate all kinds of contaminants in both well water and city water.

Water Demand

The second important thing you should consider is the amount of water you and your family use. You want to make sure you account for everything from drinking to cooking to cleaning to even all your water-using appliances like ice maker and refrigerators.

Most RO systems have a capacity of 50 gallons per day which is enough for a relatively small household. There are other systems that can produce 75 to 90 gallons each day. If you have a large family then a system that delivers 75 gallons or more will be enough.

Filtration Process

The filtration process and number of stages are also important features to consider when shopping for a reverse osmosis system. Most units have around 3 to 5 stages of filtration.

Some more advanced systems like the iSpring RCC7AK-UV feature 6 to 7 stages of filtration. These systems come with additional filters like the remineralization filter and Ultraviolet (UV light) filter.

Systems with 3 to 5 stages are ideal for most applications particularly if you reside in an urban area or your source is municipally treated water. They have all the mandatory filters required to remove all contaminants remaining in the water.

If your source is well water, then the best option would be an advanced RO system with 6 to 7 filtration stages.

Water from wells have high levels of contaminants. They require thorough filtering and an advanced system like iSpring RCC7AK-UV with 7 powerful filters can effectively clean even the foulest water.

Generally here, the more the number of stages a unit has the better and much effective filtration, purification and sterilization process the water will undergo. Therefore, make sure you choose a unit that has more than three stages, so that you are guaranteed of at least some good results.

Water Wastage

The RO system is designed such that there is always waste water produced. That’s how the technology works. So, if you are sensitive when it comes to your water bills, then this is a factor that you would want to consider too.

How much is too much and how much is reasonable? That’s the question that you need to ask yourself. The most preferred ratio is either 1 gallon of waste water for every gallon of purified water or 2 gallons of waste water for each gallon of purified water.

However, most units will produce 3 gallons of waste water for a gallon of purified water. Basically here, the higher the capacity of the unit the more likely it’s going to produce a lot of waste water. So, you choice will depend on you water demand but make sure not to pick something that produces more than 4 gallons of waste for a gallon of purified water.

Filter Life and Maintenance

The main cost of RO system is in replacing filters. It’s a long-term running cost and as such you want to ensure you pick a unit whose filters have a longer lifespan. Cheap filters usually require frequent replacements due to their shorter lifespan and as a result they end up costing more in the long-term.

Look for models that have pre filters that are changed at least once in a year. The lifespan of the other filters should range from 2 to 5 years. That way, you will be able to maintain optimum performance and reduce your running cost.
