Clean water is something that we tend to take for granted. If you are lucky enough to live in a location where the local water is clean and filtered then you may not even think of it at all. Tap water can contain magnesium, minerals, hormones, even high levels of pesticides and contaminants.Your water can be full of pathogens and you may have no idea as it does not affect the taste. But if you live in a place where the water is hard, full of minerals and contaminants, or just tastes strange out of the tap, you may feel the need for a water purification or filtration system.
Distillers are one type of water purification system. They work by heating the water up until turns into a vapor. When the steam cools, in a different area of the filter, it condenses back into water. This is one of the best ways to get very pure water. However, distilled water can taste “flat” since the oxygen has been removed from it. Distillers also cannot remove all the chemicals from the water. Distillers work slowly and can only clean a couple gallons of water every hour.
Reverse Osmosis is one of the most common methods of water filtering. Reverse Osmosis sends the water through two different liquids, separated by a permeable film which only allows water to pass through on a molecular level. The water then finishes passing through the system, leaving all impurities behind. The oxygen also travels through the filter. This method is also slow, and requires professional maintenance and filter changing.
Whole-house water purification systems are another option. These systems use a cartridge to filter the water, and work much faster than other filtering models. This type of filter also usually contains a water softener. They get hooked to incoming water pipes, and provide clean water for the entire house.
Some water purification systems can be used on specific faucets, like the under-faucet filter. This water filter is hooked up to water pipes as they go into the faucet. The water is purified before it reaches the tap. It is easy to both install and change the filters on this type of system.
Size and Complexity of the System
The cost of a water purification system is dictated largely by the size and complexity. There are small and simple water purifiers that affect just one tap in the house, and there are whole system water purification systems that clean and soften all the water coming into your home. With whole home water purification systems, there is a water softener component that treats hard water and removes minerals, and there is an under the sink water purification component that filters the tap water.
With these systems, you tend to get what you pay for. The more complex the system, the more completely it purifies your water, and the more water it cleans, the more expensive it will be. But the health benefits of having purified water in your home may far outweigh the costs.
