Pure Life water is safe to drink and meets federal safety standards, but it’s not meaningfully better for you than filtered tap water. It goes through a thorough purification process, contains trace minerals, and has a near-neutral pH of 7.3. The main concern worth knowing about isn’t the water itself but the plastic bottle it comes in.
How Pure Life Water Is Processed
Pure Life starts as either well water or municipal tap water, then goes through a multi-step purification process before it reaches your bottle. The key steps include activated carbon filtration to remove chlorine and other chemicals, followed by either distillation (boiling and collecting steam) or reverse osmosis (forcing water through an extremely fine membrane). Both methods strip the water down to near-pure H₂O.
After that, minerals are added back in for taste, since fully demineralized water tastes flat. The water then passes through microfiltration, gets disinfected with ultraviolet light (and sometimes ozone gas), and is bottled in a controlled filling room. Samples are sent to a national testing lab for verification against state and federal standards.
This is a solid purification process. It’s essentially what a high-end home filtration system does, just at industrial scale with more quality checkpoints.
What’s Actually in the Water
Pure Life contains small amounts of calcium, magnesium, potassium, sodium, and bicarbonate. These are added after purification to give the water a clean, smooth taste. The sodium content rounds to 0 mg per serving, so it’s not a concern for people watching their salt intake.
The mineral levels are too low to contribute meaningfully to your daily nutritional needs. You’d get far more calcium from a single bite of cheese than from an entire bottle of Pure Life. The minerals are there for flavor, not health benefits. At a pH of 7.3, the water is essentially neutral, sitting just barely on the alkaline side. Claims that alkaline water offers special health benefits don’t have strong scientific support, but a neutral pH like this is perfectly fine for everyday hydration.
The Microplastics Question
This is where things get less reassuring. A 2018 study published in Frontiers in Chemistry tested 27 lots of bottled water across 11 brands and found microplastic particles in nearly all of them. Pure Life had some of the highest concentrations, averaging around 930 microplastic particles per liter across the lots tested. One lot purchased through Amazon contained an average of 2,277 particles per liter, with a single sample spiking as high as 10,390.
These particles are tiny, most between 6.5 and 100 micrometers (smaller than the width of a human hair). Scientists are still working to understand the long-term health effects of ingesting microplastics at these levels. The contamination likely comes from the bottling process and the plastic packaging itself rather than the water source. This isn’t unique to Pure Life. It’s a problem across the bottled water industry, though Pure Life ranked among the higher results in that particular study.
BPA and Bottle Safety
Pure Life’s single-serve bottles (8 oz to 3 liters) are made from PET #1 plastic, and their larger containers use HDPE #2 plastic. Both are BPA-free. Their recycled plastic (rPET) bottles are described as “virtually BPA-free” because the recycling process introduces a small theoretical risk of cross-contamination from other plastic types, though the company screens and sorts materials to minimize this.
PET plastic is generally considered one of the safer options for food contact. However, heat can cause chemicals to leach from any plastic bottle, so storing bottled water in hot cars or direct sunlight is worth avoiding regardless of brand.
How It Compares to Tap Water
The FDA regulates bottled water, while the EPA regulates tap water. Both set limits on contaminants, but they operate differently. The EPA requires public water utilities to test frequently and publish annual quality reports that anyone can read. The FDA requires bottled water companies to follow safety rules and test their water, but the results aren’t as publicly accessible.
In most U.S. cities, tap water meets or exceeds the same safety thresholds as bottled water. If your local tap water tastes fine and your home doesn’t have old lead pipes, a simple carbon filter pitcher will give you water that’s chemically comparable to Pure Life at a fraction of the cost and without the microplastic exposure from plastic bottles. If you live in an area with water quality concerns, or you need portable water, Pure Life is a reasonable option.
The Bottom Line on Daily Use
Pure Life water is properly purified, low in sodium, free of chlorine, and safe by regulatory standards. It will hydrate you exactly as well as any other clean water. It won’t deliver meaningful mineral nutrition, and no bottled water will. The real trade-off is convenience versus the microplastic exposure that comes with any water sold in plastic bottles. For occasional use, it’s perfectly fine. For your primary daily water source, a reusable bottle filled with filtered tap water is cheaper, produces less waste, and avoids the microplastic question entirely.
