Having a water purification system in your home is becoming a requirement these days. If you want to protect yourself and your family from all of the chemicals and harmful substances that can be left in tap water, water filters are the perfect solution. There are a few different types of filters available. Each work differently and can remove various chemicals from the water we drink.
Carbon water filters are probably the most commonly used filters in the home. They work by passing the water through a porous filter before it comes out of the faucet, pulling various substances from the water. They can be purchased as a water pitcher, an attachment to a pipe under the sink, or as an alternative to the faucet.
Carbon filters can eliminate chlorine as well as pesticides, lead, several different types of bacteria, parasites, and organic compounds.
Reverse osmosis is a water purification system that requires two compartments of water and a semi-permeable membrane. The filter sends the water being cleansed through the membrane so that several different components are removed. This type of purification may also be used in conjunction with a carbon filter. The problem with osmosis is that a great deal of water is wasted in order to purify a small amount. Generally, five liters are wasted in order to create one clean liter of water.
Reverse osmosis can get rid of sulfates, perchlorate, chlorine byproducts, and pharmaceuticals.
Distillers are probably the most out of date water filters on the market today. These are designed to boil the water in order to sterilize it. This leaves the water tasting a bit flat since the oxygen is lost. The process is incredibly slow, taking an hour to purify 3 liters of water. Also, not all chemicals can be removed with this process. Any substance that can withstand the boiling point of water will remain. Distillers are used on the countertop, require regular cleanings, and use a great deal of energy.
Distillers typically remove microbes, lead, mercury, and various metals.
Ultraviolet light filters use light to kill the bacteria found in water. They work best when used in combination of with a carbon filter, because they cannot remove metals and other forms of contaminants. These type of purification can be very expensive. A countertop version can be bought for just under $100, but a unit that works with the entire home will cost approximately $700 or more.
Every home owner should consider purchasing a water purification system for their home. These filters work to remove harmful substances from the water you drink and bathe in. Different types of filters work differently, but all will help to eliminate hazardous materials.
