Guide to How Water Purifiers Work
Water makes up two-thirds of the human body, which is why it is important to consume eight glasses of water a day. Because water is so vital to the body, it is extremely important that the water you consume is clean. This is where water purifiers come in. While most people know what a water purifier is, most people do not know how they work.
Basic Concept
Filtration is the basic concept behind all water purifiers. This process involves removing all contaminants from your drinking water by sifting them out. While there are two main types of water purifiers, they both involve using a filter to catch contaminants, therefore, only allowing the clean water to pass through. Most tap water in the US is not dangerous but trace amounts of harmful contaminants, including lead, pesticides, and pharmaceutical drugs.
Gravity-Based Water Purifiers
This type of water filter works by holding water in the upper portion and allowing gravity to pull the water through a filter. As the water flows through the filter, the contaminants are trapped on the other side. Metal strainers are also often added to make sure that no contaminants make it through. The biggest downside to gravity-based water purifiers is that they filter the water at a slow pace, which is not practical if used for a large family.
Activated Charcoal Filtration System
This type of water purifier works by using activated charcoal to absorb the contaminants that are contained in the water. While studies have shown that activated charcoal works very well at absorbing contaminants, this type of system also has its downside. The activated charcoal in these water purifiers has to be replaced in order for it to continue to function properly, which can lead to this type of filter costing much more than the gravity-based type in the long run.
Combination System
You can often purchase both of these types of filters together in bundled water purification systems. The combination of the two is a great way to make sure that the water you and your family drink is free on harmful contaminants. While the cost of purchasing one of these systems may seem high, it is much less expensive than purchasing bottled water.
