Quality Water Filters 4 You Posting Page

It is no secret that drinking water is rarely ever 100 percent pure. Even the best, most expensive water filter cannot achieve that result. Water distillers can come close to achieving that result, but not without some drawbacks. So, which is best for the average home or office in terms of safe drinking water? A water filter or a water distiller?
In most drinking water there are certain impurities. These include chlorine, dissolved minerals, iron, and microbes. Filtration, as well as distillation, will remove these impurities. Each method has its own pros and cons which often determine which method the consumer chooses.
A water filtering system does just that—it filters the water as it comes into and through the filter unit. As the incoming water is forced through the filter's membranes, impurities are removed. The manner in which the water is forced through the membranes can vary from one system to the next. Some units use gravity, others use pressure, and some will use a pump to force the water through the system.
It is important to remember that the overall effectiveness of the water filtering system depends on the type of membrane being used. Membranes that have smaller pore sizes will catch more contaminants than units with larger pore sizes. In addition, some units will also include activated carbon or other types of resins to help absorb various impurities.
The advantages to using a water filtering system include their low price, ease of use, and availability. The most common disadvantage is that the membrane filters have to be replaced from time to time.
In water distillation systems, the incoming water is boiled and the water vapor that is produced is collected and allowed to run down into a cooling chamber. As the water vapor rises, any impurities are left behind, thus producing very clean water.
Water distillation can remove virtually all contaminants, and because the water is boiled, it also removes dangerous microbes. The main advantage to distilling water is the resulting pure water. However, there are many disadvantages.
The disadvantages to distilling water are that it often produces a flat taste which some people do not enjoy. Also, the units are expensive and cumbersome, not easily moved from one place to another, and they do require significant energy during the boiling process. Lastly, the process is very slow.
For the vast majority of consumers, a home or office water filter is the best option. These units are easy to install and are priced very reasonably. When choosing a unit, try to get one that has the smallest pore size that you can afford. You should not buy a unit that has a pore size above 0.1 micron, as this is the size that will remove Giardia and many other contaminants. In other words, this should be the minimum size you purchase.
You can find a variety of water filters online and even order online as well. Read the manufacturer's literature and buy the best unit you can afford. This will ensure that your drinking water will be clean and fresh for years to come.
