Top 5 Reverse Osmosis Systems In This Review

1. APEC Water ROES-PH75

2. APEC Water RO-90 (Not RO-PH90)

3. iSpring RCC7 5-Stage

4. Home Master TMAFC Artesian Full Contact (the version with Pump is TMAFC-ERP)

5. APEC ROES-50 5-Stage

First, let me tell you why we need and purchased for a reverse osmosis system.

Even though public water suppliers clean our tap water, there are still thousands of contaminants that appear in our water at home. The Flint water crisis in Michigan made me think about my family’s health.

Our reverse osmosis system (APEC ROES-PH75) cleans tap water far beyond what municipal systems can do. It removes all sorts of contaminants that would otherwise go right into our food and drinks.

While researching reverse osmosis systems, I discovered that this type of water filter can last for years, doesn’t need a lot of maintenance, and isn’t hard to install at home.

APEC Water ROES-PH75 Review

APEC’s 6-stage reverse osmosis technology removes bacteria, viruses, amoebic cysts, asbestos, metals like lead, radioactive contaminants, chlorine, and all sorts of chemicals that cause tap water to smell and taste bad. The fact that it removes so many impurities from my home’s tap water relieves me from worrying about the municipal water supply being contaminated.

  • The first stage of the filter removes rust and sediments.
  • The second and third stages clear out chlorine and other volatile organic compounds often present in city tap water.
  • The fourth stage gets rid of bacteria, viruses, and other tiny pollutants and particles.
  • The fifth stage is a carbon filter that removes ant remaining odors and tastes from the purified water.
  • The sixth and final stage on the ROES-PH75 filter sends the clean water through food-grade calcium carbonate before it goes to the faucet. The calcium carbonate makes the water more alkaline and gives it a slight mineral taste.

My family prefers the flavor and it encourages them to drink more water, which is a healthy habit. That’s one of three reasons why I chose this system over the other APEC models I’ll talk about below.

A second reason I selected the ROES-PH75 is because studies show that drinking alkaline water is healthier. It can help counteract a high-acid diet and fight cancer. This helps me to protect my family from ill health.

The final reason I chose the ROES-PH75 model is because it treats up to 75 gallons a day. It refills its pure water tank swiftly. That’s important to me because I have a busy family and we use a lot of water for drinking and cooking.

Even with daily use, I’ll only have to change some of the filters once every 6 months. The main contaminant filter, or 4th stage, only needs to be changed every two to four years. The filters aren’t very expensive, so I’ll be saving money over buying bottled water.

There are a couple of other features about this system that I like. APEC only uses food-grade components and has strict controls over their production environment. Their products are made in the USA, and come with a 1-year warranty.

APEC included easy-to-follow instructions so I was able to install the ROES-PH75 myself under our kitchen sink. I only needed a few tools and a drill. The package even included a stylish water faucet. The reverse osmosis system itself was very easy to put together with labeled parts and color-coded tubing. Changing the filters in a few months will be a snap.

Here’s a quick summary of the pros and cons about the APEC ROES-PH75:


  • Removes up to 99% of any contaminants hazardous to health
  • Works quickly to refill its tank because it’s rated for 75 gallons per day
  • Food-grade parts including the lead-free faucet
  • Silent operation
  • Doesn’t need electricity to run
  • Easy to install at home without a professional
  • Made in the USA with strict quality controls
  • Water tastes good and comes out slightly alkaline for better health benefits


  • I’ll need to buy the ice maker kit separately to hook the filter to our refrigerator

Of course, before I purchased this reverse osmosis system, I researched other options. I’d like to tell you about four that were recommended by many other water filter users.

APEC Water RO-90 Review (Not RO-PH90)

The RO-90 is APEC’s top-of-the-line 5-stage filter.

This model has the coveted WQA Gold Seal Certification because it removes up to 99% of contaminants like heavy metals, bacteria, viruses, and more.

With a higher flow rate, it delivers up to 90 gallons of pure water a day.

The only thing the RO-90 lacks is the 6th stage filter that adds mineral flavor and makes the water alkaline. Although it doesn’t have the sixth stage, the fifth stage uses coconut carbon fiber to remove any remaining flavor or odor from the water.

Like the APEC ROES-75, the RO-90 is easy for an ordinary person to install. It comes with color-coded parts and simple-to-follow instructions. The included faucet is lead-free and the tubing is all NSF and FDA-certified food-grade.

Here’s a quick summary of the pros and cons about the APEC RO-90:


  • WQA Gold Seal certified to remove up to 99% of thousands of impurities from tap water
  • Works very quickly, cleans up to 90 gallons of water per day
  • Easy to install without needing a plumber
  • Food-grade parts include the lead-free faucet and tubing
  • Doesn’t need electricity or batteries to operate
  • Works silently
  • Made in the USA


  • Does not alter acidity or add flavor

If you need fewer than 90 gallons of water purified each day, and you don’t want to add flavor, you might like these other filters below.

iSpring RCC7 5-Stage Reverse Osmosis Water Filter  Review

The RCC7 filter from iSpring can also clean thousands of contaminants out of tap water. It processes up to 75 gallons a day just like the APEC ROES-PH75 that I purchased. It’s only a 5-stage system because it doesn’t have the final calcium carbonate filter that the ROES-PH75 has. The RCC7 doesn’t alter the pH or add the taste of minerals to the water.

On the other hand, I liked the transparent 1st-stage filter. That makes it easy to see when it’s time to change it. It comes with a similar high-spout faucet like my filter system has. The whole setup appears to be just as easy to install at home, and it’s just as simple to change filters.

iSpring has achieved the RCC7 Water Quality Association (WQA) Gold Seal certification after rigorous testing. The RCC7 passes the National Science Foundation (NSF) high standards for reverse osmosis filters. Their parts are all food-grade, and the filter itself is built in the USA.

In closing, I also liked that iSpring offers a 30-day money back guarantee as well as a 1-year warranty on the RCC7.

Here’s a quick summary of the pros and cons about the iSpring RCC7:


  • WQA Gold Seal certified with all food-safe parts
  • Transparent 1st-stage filter makes it easy to monitor status
  • Processes up to 75 gallons per day
  • Doesn’t require electricity to operate
  • Easy for an ordinary person to install
  • Money-back satisfaction guarantees and warranty


  • No filter stage to alter pH or adjust flavor of the cleaned water

While the iSpring RCC7 and the APEC ROES-PH75 can process up to 75 gallons a day, that might be more than you need if you have a smaller household. The filter described below is made to clean up to 50 gallons a day.

Home Master TMAFC Artesian Full Contact, TMAFC-ERP, TMULTRA  Review

The Home Master TMAFC system filters up to 50 gallons of water each day. This may be a better choice for a small household than the large-capacity APEC filters described above.

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.

As a bonus, this system also makes the water slightly alkaline by adding minerals. The mineralization of the pure water happens in two stages as it flows through the system.

The TMAFC system comes assembled and ready to install with all the needed parts. Everything is color-coded and the instructions are easy to follow.

Like the other reverse osmosis filters in this review, this one comes with its own faucet and food-grade tubing.

Home Master’s filters only need a change about every 2,000 gallons, or once a year. They are push-in filters so no tools are needed.

Of course, since they are complete cartridges, both they and the TMAFC system cost a little more than the average reverse osmosis system. The filters create a little larger burden on the environment if you don’t recycle them properly.

On the upside, this system doesn’t waste a lot of water-it has a ratio of 4 to 1. That means it creates one gallon of pure water for every four gallons it processes.

The TMAFC has seven stages of filtration, and mineralization of the water counts as two of the seven steps.

Unfortunately, this system does not remove microorganisms like bacteria or amoebae.

Home Master also sells a 75-gallon version of this Artesian Full Contact water filter (TMAFC-ERP for instance) as well as their Ultra reverse osmosis systems that get rid of microorganisms (Home Master Ultra TMULTRA for example). Some of their filters are even more efficient with a waste to pure water “super ratio” of 1:1.

Here’s a quick summary of the pros and cons about the Home Master TMAFC:


  • Cleans up to 50 gallons of water per day
  • Slightly mineralizes the water to make it alkaline
  • Easy to install without professional assistance
  • Very easy to change filters
  • Push-in filters come with their own housings so the system stays hygienic
  • Doesn’t need batteries or electricity to function
  • Efficient ratio of 4:1 doesn’t waste much water
  • Works silently


  • May be too slow for a large household to use
  • Removes only up to 98% of thousands of contaminants and impurities from tap water, slightly less than the other brand filters
  • Does not remove microorganisms
  • Changing both filter and housing at once creates more waste for landfills

If you would prefer a system that removes bacteria, viruses, and other living contaminants, take a look at the APEC ROES-50 below.

APEC ROES-50 5-Stage Reverse Osmosis Water Filter System

APEC also offers the ROES-50 system that cleans up to 50 gallons a day. That may be ideal for families with fewer people. The setup fits into a smaller space as well.

The ROES-50 is a 5-stage filter that cleans thousands of different particles, microorganisms, and chemicals out of tap water just like the ROES-PH75 does. Other than the lower flow rate and smaller size, its only difference from the ROES-PH75 is that it doesn’t offer the 6th stage that lowers acidity and adds mineral flavor.

Unlike the iSpring RCC7, the ROES-50 is not specifically WQA-certified. Although APEC has achieved this high-quality standard on some of its filters, neither my system nor this one has it. But the ROES-50 still uses FDA-certified food-grade parts and offers a lead-free faucet.

The ROES-50 is just as simple to install at home with its color-coded parts and clear instructions. The filters are easy to change, and they aren’t very expensive. Just like the ROES-PH75, this system comes with a 1-year warranty.

Here’s a quick summary of the pros and cons about the APEC ROES-50:


  • Cleans up to 50 gallons of water per day
  • Removes up to 99% of thousands of contaminants and impurities from tap water
  • Smaller size is easier to place under a sink
  • Easy to install without needing a plumber
  • Doesn’t require electricity to operate
  • Works silently


  • Does not alter acidity or add flavor
  • May be too slow for a large family to enjoy using

All of these reverse osmosis filters have excellent features. It just depends on what you want for your home. The APEC ROES-PH75 is working very well for me.

5 Criteria I Used To Find The Best Reverse Osmosis System

I came up with certain criteria to help me choose the best filter for my home. I hope that these features can help you decide which filter best meets your needs, too.

Criteria for choosing the best reverse osmosis water filter

  1. Removes the most common contaminants found in tap water
  2. Reduces pH and adds flavor to make the water healthier and more appealing
  3. Cleans water quickly enough so no one in the family needs to wait for the tank to refill
  4. Simple to install at home by myself
  5. Easy to change filters

To keep my family as healthy as possible, I wanted a filter that removes the most common contaminants in tap water beyond what the EPA requires for safe drinking water.

Medical studies are finding that alkaline water may fight cancer and other chronic illnesses. I wanted a filter that reduces pH and adds flavor to make the water healthier and tastier for my family. This may be a feature that isn’t as important to you. For me, it was worth the added cost.

The filter needs to clean water quickly enough that there is always pure water available throughout the day.

I wanted a reverse osmosis system simple enough to install myself at home without calling on a professional.

Then, for long-term maintenance, I looked for a system that would allow me to easily change individual filters when I needed to without hassle.


Having the best reverse osmosis system helped me feel confident that my family can drink and cook with pure water. I also feel better knowing that the filter system is simple enough to maintain that others in the family could take care of it if I wasn’t at home.

With that said, I’d like to recap what I liked about each filter system so you can decide which one is the best for you.

  • The APEC RO-90 purifies up to 90 gallons of water a day, making it a top choice for large households. The WQA Gold Seal Certification proves that it is highly effective at removing contaminants. It has a 5-stage filtration system that is easy to install at home.
  • The APEC ROES-PH75 can provide up to 75 gallons of pure water each day. It removes thousands of pollutants from tap water with its 6-stage filter system. Some filters will need replacing after 6 months, while others may last up to four years. Both the system and the filters are easy to install. The 6th stage makes the water slightly alkaline and adds a mineral flavor. If you want alkaline water, or prefer a mineral taste, consider getting the APEC ROES-PH75 that my family is enjoying right now.
  • The iSpring RCC7 5-stage system also removes thousands of contaminants. It’s big selling point is that it has a Gold Seal Certification from the WQA. It can clean up to 75 gallons a day. If you want a filter that has qualified for the WQA Gold Seal Certification, the iSpring RCC7 has achieved that standard after strict testing.
  • The Home Master TMAFC Artesian Full Contact system filters up to 50 gallons of water each day. Its push-in filters come as complete cartridges with housings and last up to a year before needing a change. The two-stage re-mineralization process makes pure water slightly alkaline.
  • The APEC ROES-50 provides up to 50 gallons of water per day. It removes thousands of unwanted particles and pollutants from tap water with its 5-stage filter system. It’s easy to install and fits in a smaller space than either of the other two filter systems reviewed here.


If you have a small family, you may benefit from the APEC ROES-50 system or the Home Master TMAFC. The Home Master TMAFC has a very hygienic filter system that costs a little more, but is very easy to maintain.

If you have a large family, or plan to link an ice maker to your filter system, consider one of the high-capacity systems like the APEC RO-90, ROES-PH75, or the iSpring RCC7. These will refill the pure water tank quickly so there is always clean water available.

If you want a filter that has qualified for the WQA Gold Seal Certification, both the APEC RO-90 and the iSpring RCC7 have achieved that standard after strict testing.

If you want alkaline water, or prefer a mineral taste, consider getting the Home Master TMAFC, or the APEC ROES-PH75 that my family is enjoying right now.
