Tap water isn't the purest water; we all know that. If you're tired of the chlorinated taste and want something better, but don't want to pay the price of store bottled water, why not pick up a drinking water filter? You can find many different types on the market today, from very simple systems that do a good basic job to complex systems that deliver bottled-water quality water to your kitchen sink.
Basic activated carbon filters are the cheapest drinking water filter solution you'll find. These filters are sold at your local grocery store for less than $50 for the faucet connection and initial filters, and replacement filters are very inexpensive. The water from these filters is very good; they work by forcing ordinary tap water through layers of activated carbon. The carbon pulls impurities from the water as it passes through, retaining chlorine and bacteria while allowing purified, better-tasting water through. Your water comes out cleaner, and retains most of the healthful minerals like calcium that make drinking water so good for you.
To eliminate serious contaminants such as lead or high chlorine levels, a reverse osmosis drinking water filter is probably your best bet. These complex but ingenious devices can be installed right under your kitchen counter. Working with a filter that allows only pure water to pass, they slowly eliminate toxins from your tap water, holding purified water in a reservoir that you access through a separate tap on your sink. Though these filters work slowly, they can provide plenty of drinking water for your family each day, even filtering salt from ocean water and eliminating most biological contaminants as well. These filtration devices use as much as ten gallons of water for every single gallon of drinking water they provide, so they aren't ideal for every household.
A reverse osmosis drinking water filter gives you very pure water, often better than store-bought water, for about five cents a gallon in most places. While the rejected water is as much as ten gallons for every gallon of pure water created, it's pure enough that it can go into your gray water storage and be used to water your garden, ensuring there is no wasted water.
Ultraviolet drinking water filter systems are often added at the end of reverse osmosis filters and other types of water filters to eliminate living contaminants like bacteria from your water. These work by shining powerful UV light into your water, killing everything in the water before it reaches your faucet. These are particularly good additions to reverse osmosis water filters; biological contaminants are one of the few things that can get through these filters, and a single plasmodium can contaminate your entire reservoir.
Ceramic filters are a type of drinking water filter that use diatomaceous earth, a natural silicon filter commonly used in commercial water treatment. This filter works similarly to an activated carbon filter, capturing your contaminants before they reach your faucet, and the resulting water is at least as good as that from an activated carbon filter.
Use your own needs and budget to determine which type of drinking water filter is the best choice for you. Osmotic filters are perfect for people who spend a lot of money on grocery-store bottled water, while those seeking just a little more filtration in their tap water will do well with ceramic and carbon drinking water filters.
