The only way to make many sources of water safe is through the process of water purification. Water purification occurs naturally in some instances. Since it is the process of passing water through a material that will filter out certain impurities, some waters that pass through rock or earth are naturally filtered. An example of this would be well water.
But many times the ground water that is extracted has very poor quality water, and must be purified or filtered further in order for it to be safe for human consumption. There are a number of techniques in addition to filterization that are used to purify water: electrode ionization, ion exchange, distillation, reverse osmosis and boiling.
Most large municipalities supply water to their citizens through water system that processes water from entry through exit (sewage). In addition to guaranteeing a supply of water to the citizens, who all want their air cooler, their water better, etc., the goal of these systems is sanitation, and so the water is purified before it is piped to homes. In addition, the municipality may determine it is beneficial to treat the water in other ways, for example by adding fluoride or conditioning hard water to make it better for household use.
There are many issues facing suppliers of municipal water. The addition of fluoride is a controversial subject, accidents have occurred in water treatment plants that have actually made the water safe to drink, and gigantic water supplies such as this are viewed as a prime terrorist target.
City water supplies are cleaned to a certain extent, but that does not necessarily mean that the water supply will be good tasting. For this reason, many people with city water have opted to add further water filtering to the water supply as it enters their homes.
There are many options, from whole house systems, to under the counter filters, all the way down to pitcher filters. Filtering water has become such an integral part of our lives that most homes have at least one of these types of filters. One of the biggest goals is to remove chlorine and chemicals such as that from the water to make it taste better. It all depends on the kind of water that is being received in the first place. There may be different kinds of contaminants in each water source, so different kinds of water processing may be necessary.
Because so many people do not like the taste or contents of municipal water, they insist on further purifying the water from their faucets. There are hundreds, if not thousands of choices on the market for the consumer to choose from to clean his home water. And of course, as we see from the ubiquitous bottle in everyone's hand nowadays, there is bottled water for when you are not at home.

Whatever kind of water filter you may have (and there are many different kinds these days, from faucet mounted, counter top versions, or under the sink types), you have to be diligent about changing the replacement cartridge in the filter. You may have bought a water filter that came with an automatic supply of replacement cartridges, but if you didn't, it is really important that you go out and buy them. You can get them at the same stores you buy air cooler filters from. Buy more than just what you need, since it is a good idea to have replacements on hand so you can change the filter cartridge as soon as you have to. The whole idea of putting in a water filtering system was to have fresh, clean water at your fingertips, right? Well, if you don't change the cartridge filter, the system will no longer be able to do its job and you will no longer have nice clean water.
A water filtering systems works as follows: the water that passes through the system has deposits, minerals and other pollutants in it. As it passes through the filter, the filtering agent removes these deposits and fresh clean water comes out of your faucet. After a while, however, these deposits build up and the filter no longer can remove new deposits. It is time to change the filter cartridge. If you read the instructions that came with your filter, you will find out how often you have to change the filter cartridge and also the specific type you should get for your water filter system.
It is really a simple matter to change the water filter cartridge, so there is not excuse not to do it on time. Just shut off the water at the valve and unscrew or pull off the filter, depending upon the style. Put the new one on. Simple and fast, no? If you make a point of keeping a supply on hand, it will be really fast since you don't have to run out to the store to get a replacement.
Keeping the filter cartridge changed is paramount to keeping the system doing its job properly. If you value the clean, fresh water you have been drinking since you put in your water filtering system, you will want to make sure that you keep it that way by changing the filter cartridge when you are supposed to. If you don't you will have a system that you paid for and that is now doing absolutely nothing for your water supply.
