» SodaStream Water Filters

how much soda do people drink per yearCarbonated drinks, often referred to as soft drinks, soda or soda pop, have roots that date back to the ancient times of the Greeks and Romans. In 1809, the first US patent for "soda water" was awarded. The experimentation with water carbonation and flavors continued until 1886 when a pharmacist, John Pemberton, mixed coca with soda to develop the world famous Coca-Cola. Today it is estimated that soft drinks represent 25% of the beverage market, with Americans drinking an average of 49 gallons/year (bottled water is second, with an average of 34 gals per person/year).

The ingredients and process of making soda is rather simple. The main ingredients are water, infused with carbon dioxide (about 94%), and sugar/syrup which makes up about 6% of its ingredients. Until recently it was the cost of the machinery that limited people from making their own soft drinks at home.

Water Filtering Process of Major Soda Manufacturers

Whenever we drink our favorite beverages, it's all about the taste, right? The major soda manufacturers go to great lengths in filtering and purifying the water used in the production of their beverages. Water contains both naturally occurring contaminants as well as chemicals that are introduced into your water. These contaminants can dramatically affect the taste of your beverages and may be potentially harmful to your health. Below are the four basic steps used in the water filtering process when creating those great tasting soft drinks we all enjoy.

1. Clarify This process rids the water of any impurities like organic matter, bacteria, or suspended particles that might degrade taste and/or color.
2. Filter Next, water runs through a sand filter, removing any particles that remain from the clarification process.
3. Sterilize Water is pumped into a storage tank, where chlorine is added as a disinfectant.
4. Dechlorinate In this step of the filtering process, the water is run through an active carbon water filter. In addition to removing any remaining organic matter, the active carbon water filter de-chlorinates the water.

This last step of dechlorination could be considered the most important of the entire filtering process. Have you ever been splashing around in the pool and end up drinking some of the pool water? Then you know how awful chlorinated water can taste. In 2005, nearly 86% of the US population was using a public water supply (1). Of these municipal supplies, nearly 98% used chlorine or its derivatives to disinfect the drinking water (2).

Because the major soft drink manufacturers are going to great lengths to produce high quality water for their sodas, wouldn't you want to use some form of filtered water to ensure that your SodaStream sparkling water is the highest quality and best tasting?

Tips for Making Better Home Soda and Sparkling Water with SodaStream

As SodaStream states on their website, now you can "turn tap water into sparkling water in under 30 seconds", and for the most part, people will want to compare the taste of the soda made from their SodaStream machine to what they are used to getting from the soft drink manufacturers. What if the results don't "taste as good", or don't "taste just like the original?" We have gathered a few tips that will help to improve the taste of your SodaStream sparkling water:

SodaStream Tips
  • Use very cold water to carbonate the water (CO2 is better absorbed into colder water)
  • After carbonating, let the bottle sit for a minute while still attached to the machine
  • SodaStream Water Filter; Use Only filtered water

If you plan on using the chlorinated water straight out of your tap for your SodaStream machine, you may find yourself very disappointed with the results. If the taste of your unfiltered tap water isn't very appealing, it's probably not producing a very good tasting coffee, tea, or sparkling water either.

There are many ways to clean up the taste of your tap water. Something as simple and convenient as a water filter pitcher can generate great tasting water. Many households today use some level of water filtration in the kitchen, whether it's an under-the-counter drinking water filter system, or a water filter inside your refrigerator for the water and ice dispenser.

SodaStream Water Filters

Let’s start with some simple and basic carbon based water filters that can reduce the chlorine in your tap water. If you would like a higher level of filtration for making soda at home, you should consider ceramic filtration in a countertop system or our newest technology, ultrafiltration (UF), that is being used by some soda manufacturers now.

Want a Cutting Edge Filter System Used By Soft Drink Manufacturers for your SodaStream?

The major soda bottlers use more than just activated carbon filtration methods. Many bottling plants utilize a multi-level filtration process that clarifies and purifies the water (as described in the paragraph above), but one Coca-Cola bottler has recently implemented ultrafiltration (UF) technology. Ultrafiltration membranes have increased the plant's capacity and efficiency by producing 10 times less waste water compared to the use of reverse osmosis. This new technology adheres to Coca-Cola's strict raw water input: not allowing more than 0.05mg/liter of chlorine and turbidity levels below 0.2 NTU's (3).
