This will set you on the right track and help you to avoid those models that do not live up to expectations. You also need to have a rough idea of what contamination is present in your water. This avoids the outlay on a model that removes contaminants absent from your water supply. The unit you choose should be able to remove all the following pollutants.

It can be deadly for children as it can impair learning and cause behavioral problems.

Lindane: This comes from run-off or leaching from insecticide used on cattle, lumber and gardens. It affects the liver and kidneys. There are two main types of water purification systems, reverse osmosis and active carbon filtration. Reverse osmosis will remove nitrates, sodium and other dissolved organic and inorganic compounds. However, it will not remove all of them. This system requires something like 1 to 5 gallons of contaminated water to produce 1 gallon of purified water. Reverse osmosis can only produce a limited amount of pure water per day. These systems tend to cost a good deal more than other than comparable systems. What features do I need in water purifier is a combination of active carbon filtration, sub micron pore filter and an ion exchange. If you look for an ion exchange unit with activated alumina this will also remove fluoride. There are three different models to choose from, countertop, under the counter and whole house water purification system. The installation of a complete house system would not be that expensive, and you could take comfort in the knowledge that all the water in your house was clean and pure drinking water.
