You are probably drinking and bathing in contaminated water. Why? Because most raw water supplies are contaminated with micro-organisms, and in order to kill these bugs, city water suppliers must add poisons like chlorine to the water. Unfortunately, the same chemicals that kill bacteria can sicken you or cause other problems, like dry skin. A home water purifier may be the answer to this problem.
There are three primary types of water purification systems: the reverse osmosis water filter, the activated carbon or ceramic water filter, and the ultraviolet purifier. Each of these acts in a very different way, and any one may be adequate to clean your water, depending on your local impurities. They are often used together as well to make an extremely good complex water purifier that addresses every water purification problem.
The most basic water purifier is the activated charcoal water filter or ceramic water filter. In each of these filters, water is forced through a granulated chemical (activated carbon or diatomaceous earth, depending on the type of filter). The chemical in the filter grabs onto impurities in the water, allowing purified water to pass through. The result: much cleaner and better tasting water. You can get shower filters that do much the same thing, but with metallic filters instead that work well in hot water conditions. All these water purification systems are the least expensive water purifiers and are adequate in most cases.
An ultraviolet light purifier is also simple, but much more technologically advanced. This water purifier is not a filter at all, but a device that shines powerful UV rays down through your water, killing any microorganisms that may be there. While it won't get rid of sediments and chemicals, an ultraviolet water purifier is among the best and most reliable removers of biological contaminants you can buy.
The most advanced home water purifier is the reverse osmosis system. These complex devices use passive osmotic filtration, allowing pure water to pass through while holding almost all chemicals and impurities on the other side to be flushed out later. Almost any chemical or biological contaminant is removed by these water purifier systems, including minerals that are good for humans like fluoride and calcium. The water resulting is of equal or superior quality to most bottled water at your grocery store.
The most complicated water purifiers use several different filters for their various advantages: an ultraviolet purifier to kill bacteria, an activated carbon filter to get rid of large sediments and many impurities, and a reverse osmosis filter to remove almost every other contaminant and store the clean water in a collection tank. You wind up with water superior to any bottled water you could purchase, all for five or ten cents a gallon.
Home water purifier systems are significantly more involved than simple home water filters. While a filter can easily be attached to your faucet by you, a home water purifier system will likely require a professional to install it, and will take up a significant amount of space under your counter or in another location convenient to your faucet. When you choose one, therefore, you'll have to think about the cost and space required by the system as well as how the system itself works. The best home water purifier system is always the one that works best for you.
When you're looking for the best home water purification system, there are several questions you should ask. First, how long will it last without needing a filter to be changed? This isn't just important from the perspective of cost, but also convenience. Depending on where your home water purification system is installed, one that requires frequent changing could be more trouble than it's worth.
Home water purification systems also vary widely in the types of contaminants they remove. Not every system will remove the contaminants you need to eliminate. Before you invest in one, make sure it removes the things you need to get rid of. One system, the reverse osmosis system, will remove almost every contaminant you may be concerned about, but it takes up a lot of room and may not be appropriate for every location in your home.
Cost is an important issue when considering a home water purifier. The least expensive home water purification system is the sort that attaches directly to your faucet, using activated carbon to filter out impurities, but you can go as far as getting an industrial-grade UV system, which destroys every known living contaminant in water more effectively than chlorine ever could, for a little over a thousand dollars. Most home water purification systems are in the two hundred dollar range, but for some, installation may take a professional and therefore cost you a little more. With cost, however, you should also look at how the filter you're choosing works. Some will provide you with all the drinking water you need and more, at bottled-water quality; if you're a big bottled-water drinker, this can save you more than the cost of installation. For those who have hard water and overchlorinated municipal water, a shower water filter can save you a fortune by helping your quality shampoos and body soaps work more effectively.
General types of home water purification systems are as follow. Reverse osmosis systems involve putting a tank under your sink for a passive osmotic removal of contaminants, and supply you with bottled-water-quality drinking water. UV systems kill any living organism in your water without contaminating it with chlorine or other harmful chemicals; this is a great option if you depend on well or spring water. Activated carbon filters remove many types of contaminants and are inexpensive in comparison to others, but they will need frequent changes. And shower filters, using KDF-55 filters, remove contaminants in your shower water, softening the water and eliminating harmful chlorine. Examining the other differences between these basic types will help you make an intelligent and informed decision about which water filtration system is best for you.
