5 Best Reverse Osmosis Systems

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.

I want the best for my family, and that includes making sure they have pure water to drink. A reverse osmosis filtration system 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.

After looking for the best system to suit my family, I purchased the APEC Water Systems ROES-PH75. It cleans up to 75 gallons of water a day and adds an alkaline component for good health and better taste. I’d like to tell you more about it below.

APEC Water Systems ROES-PH75 Reverse Osmosis Drinking Water System

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. Drinking alkaline water has been shown to improve health, so I wanted that for my family. That’s one of two reasons I chose this system over the other APEC model I’ll talk about below.

The other 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


  • 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 two that were recommended by many other water filter users.

iSpring RCC7 5-Stage Reverse Osmosis Water Filter

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 guarantee 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.

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


  • 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.

Buyer’s guide to the best reverse osmosis filter

In order to choose the best water filter for my family’s health, I did a lot of research. I considered what the manufacturers said about their products and read many user reviews. 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. Cleans water quickly enough so no one in the family needs to wait for the tank to refill
  3. Simple to install at home by myself
  4. 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.

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 water filter 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 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.

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.

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 smaller family, you may benefit from the APEC ROES-50 system.

If you have a larger family, or plan to link an ice maker to your filter system, consider one of the 75-gallon systems like the APEC ROES-PH75 or the iSpring RCC7. Either one will refill the pure water tank more quickly so there is always clean water available.

If you want a filter that has qualified for the WQA Gold Seal Certification, the iSpring RCC7 has achieved that standard after strict testing.

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

In closing

I love the sense of relief I have knowing that my family has pure filtered water for their consumption. It was worth the investment.
