There are many different options on the market today for delivering clean water to your home, from the cheap activated charcoal faucet-mounted filters to the complex reverse osmosis systems that install under your kitchen sink. While you may be tempted to go with the least expensive water filter system, you should consider your needs first. For someone who buys lots of bottled water, a good reverse osmosis system may be better; for country water that comes from a well, an ultraviolet filter may be a better choice, with its excellent ability to kill biological contaminants.

If you already have good-quality water in your taps, you may just want to use the regular PUR or Brita type drinking water filter system. These filters use activated charcoal to filter out mostly biological contaminants, but also a few mineral contaminants, and deliver clean, good-tasting water to you. The less-used ceramic water filter systems work approximately the same way, but with diatomaceous earth instead of activated charcoal.

If your water is relatively unpleasant to drink and you find yourself spending a lot of money every month on bottled water, it might be a good idea to go with a reverse osmosis drinking water filter system. The most basic of these consists of an osmotic filter where the water comes in, a reservoir where purified water is stored, and a tap separate from your regular sink tap where your purified water comes out. Where the activated charcoal water filter system removes contaminants when water is forced through the filter, an osmotic filter removes contaminants passively, allowing very pure water to seep through the filter while all contaminants remain on the other side. The result is bottled-water quality drinking water.

Reverse osmosis drinking water filter systems do have drawbacks. They take ten gallons of water to make one gallon of filtered water; the rest is used to flush out the filter. They process water very slowly, so they need a reservoir into which the purified water is placed. And they sometimes let a biological contaminant through, where it can contaminate the entire reservoir. This last problem can be solved by using a three-filter system instead of a single-filter system; in this drinking water filter system, water is first forced through an activated carbon water filter, then allowed to diffuse through the filter. Finally, just before the reservoir an ultraviolet water purifier shines powerful ultraviolet light on the water, irradiating and killing any biological contaminants while leaving the water itself pure and clear for your drinking leisure.

One unique type of water filter system you should consider: the whole house water filter system. If you have a problem with hard water or you have family members with breathing problems, these filtration systems can improve the quality of your entire water supply, removing contaminants from your shower before they get to you, guaranteeing you good drinking water from any tap, and preventing chlorine from entering your house, where it can vaporize and become chloroform, a lung irritant that can worsen asthma. With a whole house water filter system, you can rest easy that your whole household will be a cleaner, healthier place.

Whole house water filters are an excellent solution to poor water quality no matter where you live. These devices are installed at your water main before any water enters hour home, and they can remove most contaminants you're concerned about before any water reaches your family. Instead of worrying, you'll have clean, pure water with great taste from every tap in your home.

You might be surprised at the range of benefits your whole house water filter can provide you. For instance, they remove most of the chlorine from your water, which prevents chlorine from vaporizing in the shower to form hazardous chlorine gas. They can also help soften your water or at least remove much of the mineral problem in it before it gets to your hot water heater and to your family. Purer, softer water works better with soaps and cleansers, so you'll be able to use less and save money, and fewer deposits will accumulate in your shower, saving you time cleaning.

With a whole house water filter, you won't have to have a separate water filter for your drinking water supply, either; a good filter will provide you with bottled-water quality water right out of your tap.

A whole house water filter is a home improvement project, and should be approached as such. While it is a significant expense, it also adds to your home's value. These filters will take up about half the space of a standard water heater, and you'll need to hire a professional plumber to install them. Filters need to be changed out once or twice a year, depending on the type of filters you have and how contaminated your water is. Costs of your whole house water filter will be offset by savings on bottled water purchasing and by the decrease in the amount of soaps you'll need to use; if you have a problem with indoor air quality, a whole house water filter can often improve that as well, and the lung health of your entire family.

Whole house water filters come in several styles, but most include a three-part filtration system. Water coming into your home passes through a sediment tank first, where any large contaminants are allowed to settle out. The purer water passes through a carbon or ceramic filter after this, where most chemical and bacterial contaminants are filtered out by activated charcoal or diatomaceous earth. The last stage sends your water through a redox potential high filter, a metallic style filter that takes the chlorine out of your water. Some house water filters also include a UV purifier to kill any bacterial or other biological contaminants. At the end, almost every contaminant is removed from your water, but the positive minerals calcium and fluoride are still there, where they give your water a better taste and also contribute to your family's health.

Choose your whole house water filter carefully. You'll need to find out what contaminants are in your water at the main source; if you have no idea how to go about this, your water company may test it for you for free, or they'll be able to tell you where to go to have it tested. Worry more about removing all the contaminants that are a problem in your water than about how much your filter is going to cost; it will pay for itself, but only if you get every contaminant at the source. And find out how and when to change filters, and how much filters are going to add to your bill each year.

Are you looking for a great water filtration system for your home? Many people today are looking for better tasting water, or water that doesn't have contaminants from aging city systems, and most don't want to go to the expense, hassle, and waste of purchasing bottled water. Others are seeking out water softening systems to eliminate chlorine and minerals from their water systems that make soap less effective and leave behind deposits. Good water filtration can save you money, make you healthier, and deliver truly clean water to your home.

The first consideration in a filtration system is what you really need; most people start with drinking water. With bottled water often more expensive per pint than gasoline, it's easy to see why. There are several types of home water filtration systems that provide you with excellent quality drinking water, from the low end activated carbon filter to the high-end reverse-osmosis water filtration system.

The least expensive filtration system is the faucet-mounted activated carbon filter. This filtration system forces tap water through a compartment of activated charcoal, where impurities are captured in the carbon itself while clean water passes through. Filters in this system need to be changed three or four times a year with regular use, but the system is fairly effective, removing many of the harsher chemicals like chlorine as well as biological contaminants in your water and giving you fresh-tasting clean water. Similar to activated carbon filters are ceramic filters, though they use diatomaceous earth instead of carbon to perform the same function.

An ultraviolet (UV) water filtration system uses high-intensity UV light waves, shining them through your water to kill biological contaminants. These systems do not remove anything from your water, but they are the most effective at sterilizing it, and are often found as part of a combination water filtration system in which other contaminants and debris are filtered through other systems. You'll also find these powerful sterilizers in hospital water systems.

The most expensive, but most effective, filtration system is the reverse osmosis water filter. This remarkably effective water filtration system can remove salt from ocean water, and has no trouble removing almost every impurity from your tap water. Because the filtration system is slow, it uses a reservoir to store clean water under your sink. The best reverse osmosis systems include an activated carbon filter and a UV filter as well, ensuring you cleaner, better tasting drinking water than you'll find in the best bottled water.

Besides drinking water filtration systems, you can get shower filters, which remove the chlorine from your shower water. Chlorine is more dangerous in your bathroom than you might expect, as it becomes the lung irritant chloroform gas in steamy showers, and it forces you to use more soap and shampoo than you otherwise would. Metallic filters are used in showers to filter impurities from hot water, and your water should be noticeably cleaner and softer when you use one of these filtration systems.

A complete home water filtration system uses all kinds of filters to eliminate every possible contaminant from your home's water system, ensuring your family the purest and healthiest possible water, for use inside and out. These systems must be installed by a professional plumber, but they are worth the trouble.
