Every customer can rinse their bottle in our ozone machine FREE every visit prior to fill up!

Ozone is O3 oxygen gas and is the second most powerful oxidant in the world.

Oxidants can work as a disinfection agent. O3 is created organically in the earth’s atmosphere when O2 gas is warmed through the sun’s powerful UV rays. As the ozone falls back to the earth’s surface it cleanses our breathing air.

Our ozone machine pumps this O3 oxygen gas into your bottle within a matter of seconds. A spray of our purified water also shoots our simultaneously and gives your bottle a quick rinse. We do not use any chemicals. Ozone is commonly used in pools, hot tubs, and bottling plants. Eliminating the use of chlorine to kill bacteria.

OB Water Store In San Diego And TDS

We Monitor TDS On A Daily Basis

What Is TDS?

Total Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water, expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million (ppm). TDS is directly related to the purity of water and the quality of water purification systems and affects everything that consumes, lives in, or uses water, whether organic or inorganic, whether for better or for worse.

In general, the total dissolved solids concentration is the sum of the cations (positively charged) and anions (negatively charged) ions in the water. Parts per Million (ppm) is the weight-to-weight ratio of any ion to water

We check our TDS everyday and it generally runs at a reading of 2 or 3, look at the chart below to see what the TDS levels typically are for a variety of waters.
 Water Store In San Diego| TDS Chart

A reading of 2 or 3 is far lower than what typically is found for purified drinking water in the United States. Our TDS levels are checked daily and kept in a log that we have posted in the store and outside at our purified and alkaline water vending machine. Purified water is not mineral free but with TDS levels at 2-3 it is pretty close.

Here in San Diego the TDS levels are typically just under 400 and can vary depending on if you live in the north or south counties of San Diego, so a 400 reading has a lot more mineral content han a reading of 2-3. Below is a reading a customer took at their home in downtown San Diego.

 Water Store In San Diego| TDS Tap Water Reading

The TDS reading was 386 for tap water in downtown San Diego. This reading varies day to day.

While 386 is below the maximum allowable amount of 500 (per the EPA), it is still higher than the national average in the Untied States for household tap water. So why settle for that when you can have the best tasting water with the lowest TDS levels in the entire county.
