Home Water Filtration Systems
Water filtration is the process by which water for domestic use is cleaned and impurities removed. Filtration can be done at different stages of the water purification process depending on how much impurities are contained in the water. Home water filter systems could rage from simple physical barriers that are attached to the water faucets to complex processes that involve the use of chemicals and biological processes to filtrate the water.
Common Home Water Filters
The granular activated carbon filter is usually attached to domestic faucets and cleans the water by absorbing chlorine and chloramines from water. It also removes other contaminants, and also removes or reduces odor and bad tastes. Another common home water filtration system is the metallic alloy filter. They are also attached to domestic water outlets. They are made from copper-zinc alloy that react with chlorine present in water therefore filtering it.
Ceramic filters are another type of home filtration systems. They involve passing water through chambers whose outlet allows only water molecules to pass through. This kind of filters can only filter dirt, bacteria and debris but cannot filter chemical contaminants.
Installing Home Water Filtration Systems
There are two main ways of installing home water filtration systems. They can either be mounted on the faucet or the plumbing system. Mounting on the faucet is much easier and it costs less money. However, it requires constant filter cleaning and changing. Having a filter system installed in the plumbing is more expensive but it does not require much cleaning and maintenance.
Before deciding on what water filtration system to purchase for your home, it is advisable to have your water tested for impurities in order to determine which type of filtration system to purchase. According to the impurities contained in the water, consumers have the option of buying an in-line reverse-osmosis system or a carbon filter. Carbon filters are mainly used to filter water that contains organic chemicals, chlorine, pesticides or chloroform. Reverse-osmosis on the other hand is used to filter water that has organic contaminants, sodium, nitrates, ferrous iron, lead or fluoride.
Advantages of Home Water Filtration Systems
One of the main advantages of home water filtration systems is the fact that they enable users to have clean water for drinking. They can also be used to soften hard water that is used for laundry and other uses in the house. When laundry is done using soft water, it leaves the washing much softer and less detergent is used.
Most home water filtration systems come with a meter that indicates when the user needs to change the filter. This ensures that they do not drink unfiltered water because there is no chance of forgetting to replace the filter. Another advantage is the cost effectiveness of home water filtration systems. After installation, not much maintenance and upgrading is required. Users may however need to change the filter once in a while.
Using water filtration systems also saves the user money in terms of medical bills. Drinking unfiltered water is mainly associated with certain diseases. With the use of water filtration systems, people are assured of a happy life and healthy lifestyles.
Water filters are specialized sieves used to ensure that water is clean and safe for drinking. With water being vital to the survival of humanity, the use of water filtration systems is of great importance. Unfiltered water carries with it sediment and microorganisms that may be harmful to ones health. This makes the addition of a filtration system in the home of great value.
There are different types of water filters available commercially that intend to serve the same purpose - making water safe for use. These filters use various processes such as distillation, reverse osmosis and carbon bonding.
The distillation process involves boiling the impure water until it vaporizes leaving any particles in it behind. The vapor then passes through a device that cools it back to liquid form. This process, tested in laboratories using an apparatus known as a distillation tank, has proven quite effective.
Reverse osmosis is a more complicated process. The water molecules, which are under great pressure force their way through a thin film or membrane. The membrane blocks substances in the water from seeping through. Reverse osmosis has proven effective in removing heavy metals such as lead and aluminum from water as well as microorganisms like bacteria and viruses.
Systems that use carbon in the filtration process work through adsorption. The carbon filtration process is composed of two distinct procedures, chemical bonding and mechanical straining.
In Chemical Bonding, an activated piece of black charcoal, which is hydrophorbic, is used. The black charcoal has an electro-positive charge that makes it a more attractive bonding agent to chemicals and other impurities. As water forces its way through the carbon, it passes slowly to allow sufficient contact time. This enables sediment in the water to attach to the carbon.
The second method of water purification using carbon is mechanical straining; carbon compressed into a solid block is used. Water molecules strain through the carbon blocks microscopic pores and effectively eliminate any particles. This method is more effective in removing a larger number of contaminants than chemical bonding because it has larger surface area of carbon.
The degree of effectiveness will depend on the flow rate of water and the contact time with the carbon. If the flow rate is too high, the filtration could have zero efficiency. These carbon filtration methods are more efficient in removing sediment, chlorine, and organic compounds from water. They are not as effective in removing dissolved inorganic compounds, minerals or salts.
These filtration systems have all proven to eliminate harmful organisms from water to a certain extent. Although water filter manufacturers claim that their products eliminate all impurities in water, the truth is that no filter is 100 percent effective. Human error as well as malfunction of the filtration system is possible.
When purchasing water filters, it is important to take note of the filtration process they use. Most people prefer those that incorporate distillation while others prefer a combination of several processes. Water filters are effective means of purifying water.
Water Filtration Systems
Our environment is not as clean as it used to be. The rise of industrial manufacturing plants and other technological sites continue to pollute our surroundings. It does not affect only the air we breathe in, but also the water we drink. People do not trust the natural source of water anymore. The water from our faucets are not that clean anymore, and could pose health problems when drank in great amounts.
This phenomenon brought rise to the home filter systems. Let?s deal more with this below.
Steps on Choosing a Water Home Filter System
Water filtration systems remove the impurities out of tap water. The most common models use reverse or carbon osmosis filtration. In purchasing a water filter for your home, make sure that it is duly certified by NSF International. This means that it has passed the standard requirements of a good filtration system.
Choose the right filter that fits your faucet, and have it installed by a skilled plumber. Here are some tips to consider in choosing your filter.
First, hire a professional to test your water. You will know what kind and how much filtration is needed based on the test results.
You can choose if you want to have a faucet-mounted system or other types. Faucet-mounted systems require little time to install and are generally inexpensive though they require in-line systems or regular filter changes. In-line systems may cost a lot of money but are more comprehensive. In-line systems only require rare filter changes.
Look into a certified carbon filter by the NSF for either system if the test results come back with chloroform, chlorine, organic chemicals or pesticides. Carbon filters are not proven effective against heavy metals and lead as well as fluoride and chloroform along with microbial contaminants.
Decide whether you want to use an ?in-line reverse osmosis water filtering system? if the test results indicate presence of ferrous iron, sodium, fluoride, organic contaminants and lead. The reverse osmosis system wastes a lot of water and puts limited amount of water for drinking purposes. Approximately 4 gallons of water are wasted during the filtration for a gallon of drinking water. You will need a water softener along with the in-line system if the calcium count of your water is high.
Consider a filtration system with a ?performance indication device? or cutoff meter that tells you when it is time for a filter change.
Types of Home Water Filtration Systems
There are two major types of water filtration systems and these are ?whole house water filters? and ?point of use water filters.? The first one cleans the water for the entire house. The second type filters the water and makes it clean up to a point when it is being used.
Cleaning the water for the entire house is difficult and costly and this is why ?point of use water filters? is the most practical to use. Examples of these are the pitcher water filters, shower water filters, refrigerator filters and countertop water filters.
The most popular types are those attached to faucets. This filter is simply screwed onto the faucet. There is a variant that could be attached to the showerhead also. Such types are usually based on carbon filtration system. They are simple and easy to use, cheap and do not cause any problems upon installation. The major downside of these types is that they must be changed frequently to achieve the best results.
Another kind is the countertop water filter. It can remove up to 99% of contaminants. You can sometimes attach UV light source for more effective cleaning. There is also the under sink or in-line water filters. It is installed by professionals somewhere not visible to the residents.

The Top Filtration Choices Based On Consumer Water Filter Reviews
Having pure drinking water is a very important step toward maintaining good health, but these days there are more options for ensuring a clean, pure water source than ever before. In fact, there are several different kinds of water filtration systems available for home use including the water pitcher filter, faucet filters,undersink filters,and whole house filters.
But how do each of these water filtration systems work, and which models have been shown to be the best quality units to buy according to consumer review organizations and surveys?
Water pitcher filters are extremely easy and simple to use, as all you have to do is fill the pitcher up and and watch the water filter through. Their simplicity and portability make them a very popular choice for lots of consumers. According to information gleaned from several water filter reviews the PUR Ultimate Pitcher is rated very highly for removing off-tastes and many contaminants and cysts. The filter is able to handle up to 40 gal. before needing to be replaced at a cost of nine dollars each. The biggest drawback with water pitcher filters is that they take a while to actually work, about 15 minutes at a time. So if you need drinking water quicker than that, a different water filter system will be needed.
Faucet mounted water filters are very popular these days and you see them advertised almost everywhere. They are very easy to install for even the most technically challenged among us, and are much quicker than water pitcher filters. They mount on the end of your water faucet and allow you to choose between either straight tap water or filtered water by just flipping a lever. They are very inexpensive to buy and their filter cartridges usually last two to three months. One of the most highly rated models of faucet mounted water filters is the GE Smartwater GXFM03C, which performed extremely well in most tests for both off-tastes and pollutants. It is capable of filtering out down to .5 microns for contaminants, and also does very well on sediments and cysts.
Undersink water filters usually do a little better job than the water pitchers and faucet mounted filters. However, often professional installation will be desired unless you are extremely handy around the home. Some advantages of using undersink water filters are that the water flow is extremely good, and the filters only need to be changed about once every six months or so at a cost of $20 each. A very highly rated model of undersink water filter is the Kenmore Dual 38460. All consumer reviews and ratings of this particular product were extremely high, and it would most likely make an excellent selection.
Whole house water filters do just what the name implies, they provide water filtration for the entire home simultaneously without having to be installed at each individual water faucet. Many homeowners see that as a real advantage, however the biggest disadvantage would have to be the fact that these kind of water filters will most likely require the services of a professional plumber to install properly, adding to its overall expense. Once again, Kenmore makes a highly recommended model according to most consumer reviews, the 38440. It attaches to the water main and can provide filtered water not only for drinking but for bathing, laundry, and other uses as well. Water flow rates are exceptionally good, and filters only need to be changed about every six months at a cost of about $15 each.
By reading through consumer reviews and ratings, you can get a pretty good idea of which models seem to be performing best for most people. Hopefully the information we have provided here will help you choose a high-quality, reliable, water filtration system for your home.
