Should I Drink High pH Alkaline, Reverse Osmosis, or Deionized Water?

So. You know you need filtered water for so many different reasons. You’ve done your research, read the studies, assessed your budget. You’ve even decided buying water in bulk is the best way for you and purchased a crock and a couple of 5 gallon, BPA free bottles.

Ready to just fill up and get going, right?

Then, you learn there are even more options: Reverse Osmosis, Deionized, and High pH Water. What kind of filtered water is best for me, for my family?

It’s totally overwhelming! So, we wrote a little crash course. 

Here’s a quick breakdown of the three types of water offered by FreshPure® Waters:

High pH Alkaline Water

FreshPure® High pH Alkaline Water has a pH of 9.5 or above. The school of thought behind drinking High pH Alkaline water is simple: Pollution of our planet, a less than perfect diet, and a stressful lifestyle can easily cause acidity in the body. So, incorporating alkaline water may help to offset the impact of daily life.

It goes through the entire Reverse Osmosis purification process, so you may drink it for reasons listed below and additional health benefits.

Great Reasons to Choose High pH Alkaline:

  1. You’re a coffee drinker. Coffee has a pH of 4.3-4.7, and is a strong diuretic (it makes you pee). Drinking High pH Alkaline water helps to balance both the acid and dehydration.
  2. You’ve been eating a particularly acidic diet that includes more sweets, meats, or alcohol than usual. Festive holiday fare is a great example!
  3. You feel a cold or flu coming on. Disease thrives in an acidic environment, so alkalinity may help you stay healthy!
  4. Trace minerals Calcium, Magnesium, Potassium, and Sodium help balance electrolytes and support your health.
  5. It has a strongly negative Oxidation Reduction Potential (ORP) (between -200 and -250 depending on the source) which is similar in health effects to antioxidants. Green tea and carrot juice (known for their high levels of antioxidants) both have an ORP of -50, while adding chlorine to water creates a disinfectant effect and high ORP. More on ORP coming soon!

RO: Reverse Osmosis

Reverse Osmosis is super-clean drinking water, perfect for daily use. The highly technical RO process removes contaminants down to 1000th of a micron from water. For a little reference, a human hair is 3-5 microns in diameter.

Literally hundreds of thousands of contaminants including chlorine, fluoride, pharmaceutical drugs, excess minerals, heavy metals, microplastics, and unregulated or emerging contaminants (chemicals and compounds not yet regulated by the EPA) are removed by Reverse Osmosis Technology.

It’s safe, delicious, and very affordable. Reverse Osmosis is a great option for anyone who no longer wants to drink their well water, city water, or bottled water

Great Reasons to Choose RO:

  1. It tastes delicious!
  2. Your municipal water supply has that “swimming pool” taste from chlorine.
  3. You live near an agricultural farm that may use pesticides which easily seep into groundwater.
  4. You want to avoid pharmaceutical drugs that may have dissolved into water.
  5. City plumbing and infrastructure can cause dangerous levels of contaminants to enter water supply, like the lead crisis in Flint, Michigan. A similar situation is coming to light in Plainfield Charter Township, Michigan.
  6. You live near an industrial plant of any kind that may dispose of chemical waste improperly. The current water crisis in Wilmington, North Carolina is one such example.
  7. You live downstream of a mine that may cause high levels of minerals to enter water. Here’s an example from Denver, Colorado.

DI: Deionized Water

Deionized Water is H20 purification on a molecular level. DI technology removes electrically charged molecules from water as well as any trace minerals left over after passing through the Reverse Osmosis membrane.

Great Reasons to Choose DI:

  1. Your humidifier, coffee machine, essential oil diffuser, or iron is getting clogged by excess minerals (hard water).
  2. Supporting your body through a special diet or cleanse.
  3. Some doctors recommend DI for folks with heavy metal toxicity.
  4. Your well water is too mineral rich (hard water).

We hope this helps you choose the best water for you!

Why Don’t pH Strips Work in Purified Water?


It’s a familiar story here at FreshPure® Waters. A customer happily fills their bottle with FreshPure® High pH Alkaline water, and checks the display to find out its real-time pH. Finding it 9.5 or above, they happily purchase water and bring it home. Just to be sure, they test with a pH strip to confirm the reading. And, find it doesn’t match.

In order to understand why, here’s a little rundown about the pH scale.

Wait, what IS pH?

Ready for a little high school chemistry rehash? Here we go.

What we commonly refer to as pH refers to “potential for hydrogen.” This determines acidity or alkalinity of a substance. A high concentration of hydrogen ions keeps oxygen from reaching your cells. This creates acidity. A low concentration of hydrogen ions means that more oxygen is free to the cell. This is alkalinity. Our cells use oxygen for cellular respiration, which is completely essential for life. Our world is filled with highly acidic substances and influences from red meat, to pollution.

Alkalizing foods and beverages are great ways to help off-set these influences and promote your health.

OK, so why did the Litmus paper give a different reading?

Litmus paper and pH test strips are designed to determine the pH of liquids such as chlorinated pools, saliva, and urine. These liquids all have minerals, salts, electrolytes, and many other substances dissolved into them. These factors affect not only pH but another important level: Total Dissolved Solids (TDS).

Litmus paper and pH strips only report accurately for substances with more than 150 ppm TDS. FreshPure® Waters TDS levels are typically less than 30ppm, keeping it well below the ability of a pH strip to provide an accurate reading.

Essentially, what this means is that FreshPure® Water Reverse Osmosis technology makes it too pure to report accurate testing with pH strips.

So, how do we know the pH is accurate?

What works:

  • Wide Range pH Test Kit using Liquid Reagent

According to chemists at the Water Quality Association (an industry association which represents all reputable water treatment companies) the most accurate method of measuring pH in water is the Digital pH Meter, which is what we use on our equipment. These meters must be calibrated periodically to ensure accuracy. Our technicians use a Wide Range pH Test Kit to confirm this calibration. A Wide Range pH Test Kit utilizes reagent drops to measure pH levels of low TDS, highly purified water. They are much more reliable and accurate than pH strips, and they are able to measure higher pH levels.


We hope this helps! And, we truly love hearing from our customers. Please feel free to call and ask us any questions that arise about the science behind this testing process at: 1 (800) 471-5200
