Basic Water Filter Comparison

Here, a basic water filter comparison is carried out to help you decide which type of water filtration system to use for your drinking water.

Due to the loss of woodlands, toxic chemicals, centralized water storage, and industrial contamination, it is difficult to find water that is pure. Even the water that comes in the sink contains minerals, chemicals and other impurities.

For that reason, many people prefer to use water filtering systems in order to purify their water. With so many filtration systems on the market, however, how do you know how each one works and which is best?

Distilled Water

The first process to be discussed in this water filter comparison is distillation.

Distillation is a slow process, with a quart of water taking around a few hours to produce. It also requires a lot of electricity. Some chemicals are not caught using this method, and some nutritionists argue that the loss of some of the valuable minerals that are found in the water could have negative effects. For that reason, some nutritionists encourage using mineral supplementation if using distillation.

Reverse Osmosis (R.O.) Water

The second process to be discussed in this water filter comparison is reverse osmosis.

Reverse osmosis water filter systems are one type of filtering system that get a lot of publicity. With these filters, water is drawn through a membrane with very tiny holes. The membrane acts as a filter that traps contaminates and lets pure water through. It works very slowly, but the result is water that has been filtered very finely.

While you will end up with purer water this way, an argument exists that people need the minerals that can be found in water, and that drinking reverse osmosis water long term can have negative effects on one's health; this argument is similar to that for distilled water.

Reverse osmosis water systems also tend to be expensive, and they waste a lot of water - only about 5 to 15 percent of the water entering the system is recovered as pure drinking water, with the rest being discarded. These are important points to note as you carry out your own water filter comparison.

Carbon Water Filters

Carbon water filters are also used. A charcoal filter will last around 9 months, and can filter out some of the harmful chemicals like Guardia and Cryptosporidium. These filters are also inexpensive and easy to install. In addition to filtering some of the contaminants, they can also kill harmful bacteria, too.

However, unlike the reverse osmosis systems, certain minerals and compounds which are small enough are still able to get through a charcoal filter.

Sometimes, the carbon method is used along with reverse osmosis, because carbon alone cannot get rid of harmful microorganisms, although it will give the water a better taste and help get rid of certain chemicals.

Ceramic Water Filters

The next type of filtration system to be discussed in this water filter comparison is ceramic filters.

Ceramic water filters fit onto top filters. A fossil substance called a Diatomaceous Earth, which is made up of one celled algae called diatoms, is at the core of the filter. With this type of filter, bacteria can be trapped, making the water purer. The flow rate of the water, however, can be very slow.

UV Systems

Lastly for this water filter comparison, UV systems are often used in hotels in third world countries, where serious diseases can be caught from drinking contaminated water. With the UV system, a high frequency light is used to irradiate water through glass. The light itself kills off any harmful bacteria or contaminates.

Conclusion

Knowing your water source is important if you choose to use a water filtration system. As you carry out your water filter comparison, it is important to understand that, in order to get rid of all the contaminates in your water, it might take more than one type of technology.

In addition, if you think that you might be losing important minerals when you filter your water, then you might want to consider using supplements to account for the ones that you are losing. Of course, a healthy, balanced and nutritious diet should do the trick, too.
