How to Safely Raise the pH of RO Water

“The healthier the water, the healthier the you.”

One of the downfalls of reverse osmosis filtration systems is they make drinking water more acidic. In this guide, I show you several ways to make reverse osmosis water alkaline.

Good morning, I’m your host, Hercules, the creator of AWMS and confirmed wateroholic.

I’ve started my day with several cups of pH 8.5 ionized water and my special stash of green tea.

Needless to say, I’m feeling fresh and full of energy to deliver you the best possible tutorial.

Reverse osmosis filtration systems do an incredible job of filtering water, almost too good.

First, I will discuss the pH of reverse osmosis (RO) water.

Feel free to jump between sections using the table of contents below.

What is the pH of RO water?

Like I mentioned, reverse osmosis systems do an incredible job of filtering everything out of your water.

After the water is filtered, it’s been stripped of all its minerals.

Alkaline minerals are what boost the pH of water.

Once they are all taken away, the water is slightly acidic.

According to this credible engineering forum, reverse osmosis removes the alkaline buffers in the water but does not remove carbon dioxide (CO2).

The carbon dioxide then converts into carbonic acid, which lowers the pH of the water.

Reverse osmosis water usually tests in the 5.0 to 7.0 range.

Here is a pH chart below to show you where RO water lands:

Now that we know why reverse osmosis water is acidic, let’s explore the ways you can make your reverse osmosis water alkaline.

How to Safely Raise the pH of Reverse Osmosis Water

Now that people all over the world are waking up to the realization that alkaline ionized water is healthier to drink, people like you are looking for alkaline water solutions in their homes.

If you are unfamiliar with the health benefits of alkaline water or are skeptical, check out my list of Top 25 Alkaline Benefits with science to back them up.

Since you already know that reverse osmosis water has no minerals in it, the best way to alkalize the water is by adding alkaline minerals back into your water.

If you already have a reverse osmosis filtration system, you can add an inline remineralization cartridge to your system.

However, my research led me to mixed reviews for the re-mineralization inline filters alone.

The iSpring FA15 10-inch inline filter with Calcite and Corosex looks like your best bet.

The filter uses only FDA-approved materials and adds a wide range of minerals back into your water including magnesium, sodium, ionized calcium, and potassium.

The review I saw with pH test results shown proves to me that the filter does indeed work.

One man reported a consistent pH of 8.5 for nearly a year.

Water with a pH of 8.5 is great.

Anything higher than 9.5 can be too high for drinking.

If you are new to alkaline water then pH 8.5 is perfect.

Another verified reviewer reported raising his reverse osmosis water from pH 5.0 to 7.0.

Another person reported raising the pH from 6.0 to 8.0.

iSpring advertises a pH increase of .5 – 1.2, which appears to be off since users are increasing the pH of their water by a full 2 points.

If you are interested in adding this filter to your system, you should test your current level to make sure you don’t raise the pH above 9.5.

iSpring recommends replacing the filter every 6 months or 1500 gallons.

One person recommended using the 1/4″ thread male to 3/8″ quick connect fittings below.

One of the more inspiring reviews was written by a father who said his family loves the taste of their reverse osmosis water ever since he installed the re-mineralization filter.

He reported that his son quit drinking soda because he loves the water so much.

He also noted the easy installation, saying that it only took him less than 10 minutes and required no tools.

On the flip side of the coin, some people do not like the taste and aren’t getting the pH boost they had hoped for.

Overall, the filter has 66% five-star reviews and 22% one-star reviews.

I think it’s a good option, but not the best for sure.

It all depends on how you feel about the taste.

A Complete System

If you don’t already have an RO system or want to replace your current system, there are RO systems with pH boost made by APEC that have glowing reviews online.

The cartridge APEC uses to raise the pH is made in the U.S. and uses only food-grade calcium instead of the other added minerals like in the filter above.

The system currently has over 700 reviews, and of those reviews, 88% are 5-star.

There are currently only 2% one-star reviews.

In my opinion, this system is a sure winner.

Coffee lovers will be pleased to hear that users of this system have reported an “amazing” tasting coffee.

As for the pH, one person reported going from pH 6.8 to 8.2 with this system.

Critical Considerations

While it is good to avoid drinking large amounts of acidic water, simply raising the pH of your reverse osmosis water won’t lead to the dramatic health benefits you can experience if you drink alkaline water that’s been ionized.

Most of the health benefits in alkaline ionized water come from the ionized part.

For this reason, naysayers are quick to attack “alkaline water.”

What they fail to take into consideration are the ORP value of water and the ionization phase.

When you put your water through an alkaline water machine, you get a water with a low negative ORP value that is full of antioxidants.

You can read why negative ORP water is healthy for you for by clicking here.

If you raise the pH of your reverse osmosis water without ionizing it, you’re missing out on the health-boosting properties of alkaline ionized water.

The common misconception is that the higher the pH the healthier the water.

Like I’ve said before, this is a dangerous thought process.

Drinking water with too high of a pH is unhealthy, the same as drinking water with too low of a pH.

It’s best to drink water in a pH range of 8.0 to 9.5.

And it’s smart to work your way up the ladder slowly as your body adjusts to drinking alkaline water.

That’s the beauty of owning an alkaline water machine.

With an alkaline water machine, you can choose the exact pH of your water, and you get all those lovely anti-aging antioxidants to go with it.

An affordable water machine I recommend from a trustworthy company, Air Water Life, is their Aqua Deluxe 5.0 unit.

You can see a preview of the machine below. Click the image for more information and photos:

The problem with using a reverse osmosis system with an alkaline water machine

In order for you to ionize your water in an alkaline water machine, you need to have some minerals in your water to start.

The problem is that your reverse osmosis system strips all the minerals from your water.

If you filter your water with a reverse osmosis system, you’ll need to re-mineralize it before it can properly be ionized in an alkaline water machine.

While this process will most definitely create some of the most amazing drinking water on the planet, it could be too costly for some people and take up too much space in the kitchen.

If you choose to ditch your reverse osmosis system and upgrade to an alkaline water machine, you can always install a three-stage prefiltration system if your water is super hard.

If your water isn’t too hard, the alkaline water machines have built-in filters that last up to a year that will get the job done for you.

In my opinion, the reverse osmosis system with re-mineralization in combination with a water ionizer is a great idea, but like I said, it’s not for everyone.

I’ve done tons of research on alkaline ionized water, and an alkaline water machine is always my top choice when it comes to healthy drinking water.

Boosting the pH of your water alone won’t do much in terms of health.

It may taste better and not add to the harmful acidity in your body, but that’s about it.

Avoid These Methods of Raising the pH in Your RO Water

There is a lot of information out there regarding the use of baking soda and lemon juice to raise the pH of your drinking water.

These methods are both questionable in my humble opinion.

Drinking baking soda in water throughout the day doesn’t sound like a good idea.

raising pH of reverse osmosis water with baking sodaI tried the baking soda method a couple of times about ten years ago now, and both times it gave me a strange pain in my knees.

As for lemon water, I love drinking lemon water, but I’m not on board with this method of raising the pH in water quite yet.

If you take the lemon water route, be sure to use a straw to protect your teeth since lemon is acidic.

The claim is that once you digest lemon water, it has an alkalizing effect on the body.

The main thought for you to consider is that focusing on raising the pH of your water alone is the wrong thought process.

If you haven’t already, go back and click the link I provided to read more about negative ORP water.

ORP is a measure of the antioxidant potential in your water, and the lower the ORP the more antioxidant potential you get in every glass.

For example, water with an ORP value of -800mV (millivolts) has more antioxidant potential than water with an ORP value of -400mV.

Antioxidants seek out free radicals in our bodies and help prevent premature aging.

Alkaline water machines provide the lowest ORP values you can find.

Even if you raise the pH in your reverse osmosis water, it won’t have the same low negative ORP value that an alkaline water machine can make.

Final Thoughts

In my opinion, you can’t go wrong with the APEC water system that uses food-grade calcium carbonate to gently raise the pH of reverse osmosis water.

The re-mineralization inline filter I suggested could be a bit of a dice roll if you buy it according to the mixed reviews.

It’s up to you to decide whether you think you’ll be a fan of the taste.

If you’re open to the idea of an alkaline water machine, you can click here to see my list of top 10 water ionizers and my complete guide to purchasing a unit.

Most units come with a lifetime warranty.

Several others come with a money-back guarantee, so you can essentially try before you buy.

If you’re a hardcore water fanatic, pairing a reverse osmosis system with re-mineralization with an alkaline water machine can take you to the top of Everest as far as drinking water is concerned.

Cheers and best of luck with the drinking water in your home!

Remember, we are made of 60% or more water, and nothing is more important to our continued good health than healthy drinking water.
