Brands Of Bottled Water That Are Reverse Osmosis


If you don’t have access to a water filter at home, you may regularly drink bottled water. Different companies use different methods to purify water before it is bottled, and it can be difficult to find ones that use reverse osmosis. Reverse Osmosis bottled water tastes great and you can trust that it won’t contain any harmful contaminants.

In this post, I’ll cover everything you need to know about reverse osmosis bottled water, which commercial water bottle brands are reverse osmosis, and where you can buy them.

What is Reverse Osmosis?

In any solution, there are two parts – the solvent and the solute. In drinking water, the water is the solvent, and contaminants (particulate matter, dissolved solids, sand, clay, lead, cadmium, chlorine, nitrates, pesticides, sodium, etc.) are solutes.

In reverse osmosis (RO) water purification, a semi-permeable membrane is used to filter out suspended and dissolved solids (i.e. contaminants). This membrane – with fine pores measuring 0.0001 microns, is placed between vats of water – one with a lower concentration of contaminants (solute) and one with a higher contaminant concentration.

During the purification process, pressure is applied to push the water (solvent) through the polymer matrix of the membrane. The small pore size allows only water to pass through, leaving the contaminants on one side. Then the purified water is collected.

This movement of the solvent (water) is from a region of higher solute concentration to a region of lower solute concentration. This is against the natural osmotic movement and is therefore called Reverse Osmosis.

Which brands of bottled water are reverse osmosis purified?

Here is a list of 9 companies that sell RO-purified bottled water so you can better make an informed hydration decision. Many of these brands are available in Walmart.

We have also provided links to their Amazon site pages, so you can check out their latest price and conveniently purchase online.

9 RO-Purified bottled water brands 

1. Penta Ultra-Purified Water

Penta water transforms naturally sourced water through a U.S. patented purification process that includes: micron filtration, reverse osmosis, deionization, ultraviolet light exposure and ozonation (both forms of sterilization).

This 11 hour process removes harmful chemicals such as fluoride, chlorine, Methyl tert-Butyl Ether (MTBE), lead, arsenic, bisphenol S (BPS), and bisphenol A (BPA). The Penta ultra-purified water has a pH of about 7 to 8.

Even the Penta bottling and purification process is powered by the sun to help protect the environment. Their purification process is more involved and removes more impurities compared to other brands and as a result may cost a little more.

Is bottled water the same as RO water?

In most cases, regular bottled water is not be the same as RO water.

Bottled mineral water and bottled spring water may not be subjected to RO filtration; RO removes most mineral content from the water. Bottled spring water is mostly untouched from the source – it has not undergone any artificial filtration.

Commercially bottled water may undergo additional purification processes like UV filtration, UF filtration, and flocculation. This water may be enriched with additional minerals and nutrients to add to taste.

In contrast, water purified with an RO filter at home usually does not undergo UV filtration too. Additional minerals may not be added to the water to enhance the taste. The pH of unaltered RO-filtered water is neutral, as opposed to bottled water.

The pH of bottled water varies between companies as different additives and minerals change the pH. Some companies add more electrolytes and minerals to help you stay hydrated more effectively and it adds taste

Keep in mind that RO only removes suspended and dissolved solids and is not effective against bacteria and viruses.

Is RO water better than bottled water?

To answer this question, you need to think about what is the water quality that your normally get your water from.

Contaminants

If your tap water is hard, contains a high amount of dissolved solids, or has a risk of carrying viruses, bacteria, and spores, it is recommended to stick to bottled water or invest in an RO-UV-UF filtration mechanism. This is because RO does not kill bacteria, viruses, and other pathogens.

If your tap water is relatively clean and is not prone to containing bacteria or viruses, you can opt for an RO system because it is more economical and sustainable.

Cost

Bottled water is more expensive when compared to RO water. While the initial cost of setting up an RO filter may be higher than purchasing bottled water, the cost of bottled water quickly adds up over time, and setting up an RO filter at home is more economical.

Environmental cost

There is also the environmental impact of drinking bottled water. On one hand, RO purification leads to water wastage. But on the other, most bottled water is sold in disposable single-use plastic bottles that contributes to pollution.
