There are many different water purifier machines on the market. Some use carbon, some use activated carbon and some use ion exchange or distillation. If you are looking for a water purifier machine that will give you purified water in a simple and easy to use unit, then a carbon-based water purifier machine is your best bet. They work by passing water over a charcoal or activated carbon plate. The carbon adsorbs the impurities, giving you clean water.
This type of water purifier machine is not right for everyone though. Carbon-based water purifiers emit poisonous gases, such as carbon dioxide and nitrogen, into the atmosphere. If you are not using additional filtering, then this could be okay for you. But if you have a lot of pollutants in your water supply, you might not want to purchase this type of water purifier machine. Also, because carbon-based filters require so much maintenance, they can be more expensive than other types of water purification.
An ion exchange water purifier machine actually exchanges metals found in the water, instead of trapping them. It does this through the use of an ion exchange material. It uses a combination of rare earth metals, such as silver and gold, along with other elements, to swap unwanted metals in your water with more useful ones. This type of water purifier machine will use carbon or ceramic plates to accomplish this, and they are usually smaller than other water purification units. And again, this type of water purifier machine will require more maintenance than carbon-based water purifiers kangaroo 100hc.
Distillation is another type of water purifier machine. It works by passing water over a heated coil, where the vapor is condensed. The condensed vapor is cleaner than water because it is only vaporized a few times before being condensed into water again. This method actually costs less than ion exchange and carbon-based water purifiers, but it is less effective in cleaning water. And distillers can get quite noisy. However, if you live in a rural area where electricity is available, distillers could be your best choice.
Reverse osmosis water purifier machines work by forcing water under high pressure through a semi-permeable membrane. Because water molecules are too big to pass through the membrane, the water remains stagnant or turns color. But because some water molecules are bound to the edges of the membrane, the water stays clean and is okay to drink. This type of water purifier machine might not be the best option for your home. It is also a little expensive but usually less costly than carbon and distillation.
If none of those sound good for you, there is a third type of water purifier machine, which uses ultra-filtration technology. This technology is better than the other two, but will cost more. What makes it so expensive? The fact that it takes more steps to process water than any of the other systems.
