|  Water filters are designed to resolve problems associated with harmful contaminants in water. Bad taste or smell can make water unsuitable to drink; or a high concentration of chlorine in water can make you itch or have scaly skin after you shower. So, if your goal is to improve the quality of your water and to have a better tasting and healthy drinking and shower water, this site will guide you to choose the filtration system that best meets household or commercial needs.
Your First Step? . . . Before a home or a commercial outlet decides to buy a water filter system, the first step is to test the water to find out exactly what the exact contaminants in order to choose the best water filter. Even if you are making a homemade filter, knowing the contaminants will help you buy the right parts. You can find affordable self testing kits on the market. For example a lead test costs less than $20; you can get a well test kit for almost the same amount or less. Eve if you hire a laboratory, a portable in-home self testing kit can give you the same results at far less cost. After you have confirmed what's in your water, it's easy to find the best filtration systems that's certified to remove or reduce that specific contaminants in your water without getting scammed. How to select the right home filtration There are two ways to install a water filter namely the point-of-entry (POE) systems which treat water as it enters a home or a commercial outlet; and a point-of-use (POU) which is installed at a location where the water will be used such as kitchen faucet, shower head, and refrigerator. Examples of POE systems are whole house filtrations, and whole house softening units. The POUs include countertop water filters, faucet mount, under sink, pitcher/carafe, refrigerator filter, and shower head filters. The best treatment systems are the ones that have been tested and certified by the National Sanitation Foundation (NSF) International. NSF is an independent organization that tests and certifies filters for performance. Certifications provide some level of confidence that the units you are about to buy can do what the manufacturer says it would do. The filtration system you choose should provide a statement that lists exactly which contaminants the filter is certified to reduce under which NSF/ANSI Standard. For instance, Standard 42 is for Aesthetic Effects or “taste and odor,” Standard 53 for Health Effects, like Cryptosporidium, lead, volatile organic chemicals (VOCs), and disinfection by-products, Standard 177 for chlorine in shower head. Water Treatment Technology There are several types of filtration or treatment technologies on the market. Your choice do depends on your specific water quality problems and on knowing how water filters work. | | Type | Description | Recommended Places to Buy |  | Activated Carbon Filter
These types are used in whole house, undersink, countertop, faucet mount and shower head filters. Activated carbon (AC) filters are good for improving taste and odor associated with chlorine or chlorine compounds. Most AC filters certified under NSF Standard 53-certified filters also can substantially reduce many harmful contaminants, including heavy metals such as copper, lead and mercury; disinfection byproducts; parasites such as Giardia and Cryptosporidium ; pesticides; radon; and volatile organic chemicals such as MTBE, TCE and dichlorobenzene.
AC filters are positively charged that attract and trap many contaminants and prevent them from passing through. The pores in AC filters can become plugged over time making them ineffective to remove any more contaminants. A filter label will show how often it needs to be replaced.

This is a specially designed filtration media made famous in the Multi-Pure drinking water systems. The company has been successful in developing the technology to produce filters that provide greater chemical adsorption and mechanical filtration. Materials are formed into a carbon block, which is densely compacted. Compression enhances the kinetics of the filter and provides performance that cannot be achieved with extruded or granular activated carbon (GAC) filters. Compacted solid carbon block filters have a large surface area for chemical/physical adsorption to take place. With a solid carbon block, the water contact time is longer and provides for greater adsorption of many different chemicals, pesticides, herbicides and certain heavy metals.

Reverse osmosis (RO) filtration technology consists of semi-permeable membrane that separates harmful chemicals from water. They are often used in whole house water and under sink filters; in some cases an RO can be a multi-stage filtering unit combining with an AC filter and/or ultraviolet purifier(s). The order of operation consists of a pre-filter, RO membrane unit, a post-filter and a separate dispenser for treated water, and a storage tank to store the treated water.
Reverse Osmosis filtration systems can reduce most contaminants such as the natural substances that cause foul tastes, smells or colors; and parasites such as Cryptosporidium and Giardia; heavy metals such as cadmium, copper, lead and mercury; and other major well water contaminants, including arsenic, barium, nitrate/nitrite, perchlorate and selenium.

Crystal Quest |  | Distiller
Water distillers will boil water and condense the purified steam into a receiver that comes with the unit. Distillation systems are commonly found as countertop systems but some can be installed as whole house units.
Benefits of water distillers include effectiveness in reducing nitrates, bacteria, sodium, hardness, dissolved solids, heavy metals such as cadmium, chromium, copper, lead and mercury. They can also reduce radionuclides, arsenic, barium, fluoride, selenium and sodium.
| WaterFilters.net |  | Ultraviolet Water Purifier
In an ultraviolet (UV) purifier  , water is passed through a UV light which kills bacteria and other microorganisms—depending on the dosage. UV filter systems are used with all types of water treatment units like undersink, countertop or whole house, and in most camping water purification bottles.
