What are TDS (Total Dissolved Solids)?

TDS, or Total Dissolved Solids, is the measure of the amount of organic and inorganic matter present in liquids such as water. So TDS meters measure the amount of organic and inorganic matter present in liquids such as water. In other words it is everything that is in a drop of water apart from pure molecules of H2O. TDS can originate from nature, sewage, urban runoff, industrial runoff, industrial waste and even ice that is used to de-ice roads. The higher the TDS, the more contaminated the H2Or is. When your water is treated at your local water treatment plant the aim is to remove these contaminants and make wat er safer to drink. The government provides regulations as to water purity levels. If these levels are passed water is no longer safe to drink.

The problem, however, is that not all contaminants are caught. It is becoming common knowledge that in many parts of the world there is Lead and Copper in tap water. Depending on the levels of these metals present in your local water supply it sometimes can lead to health problems. It is therefore up to you to ensure that you don't have these metals and other contaminants in your drinking water. Some people think that bottled water is the answer. It isn't. Bottled water is not only expensive, it has environmental impacts. The best thing to do is to buy a water filter jug to purify your water. It is easy to use - just put tap water in the jug and it is pure and ready for you to drink. Here is how to select the best one.

• Find out what contaminants are in your local supply of water. Contaminants in tap water differ from place to place, and not all water filter jugs are designed to catch all contaminants. Once you know what is in your water you can buy a water filter jug that targets your specific water contamination problem.
• Decide how much you want to spend. These water filter jugs come at varying price points. If you read reviews you will find that there are some very expensive models that don't do the job, and cheaper ones that are excellent purifiers. In other words, paying more for a water filter jug doesn't guarantee that you will get purer water.
• Check which design suits you best.
