Like all other consumer durables, there are a numerous options to choose from when buying a water purifier. Each company touts the technology used in their products as the best. Unfortunately, with so many brands and products in the market choosing one can be nothing short of perplexing. So let’s take a look at the there most popular types of water purifiers in the market and what they do:
Reverse Osmosis Purifiers: This type of purifier has a semi permeable, porous membrane that is used to filter the water. The pores are tiny enough to trap the larger molecules of contaminants and let the smaller molecules of water pass through.
However, reverse osmosis is ineffective against contaminants like chlorine and other chemical or pharmaceutical impurities in water. Also, a reverse osmosis purifiers not only removes the impurities but also the essential minerals that have large molecules
Water distillation Purifiers: As the name suggests, these devices distill water; the purifier typically has two containers, one that is used to store water which is subsequently boiled to the point where it vaporizes; this steam then travels through a pipe into the second, adjoining container where it settles and turns into water.
The process is very simple: the heavier contaminants do not vaporize so they are left Poner purificadora de agua behind in the first container. But water distillation cannot remove chlorine because it also vaporizes with the water, also because several essential mineral are heavier than water they too are left behind in the first container.
Multi Block Purifiers: These are by far the most effective and efficient products in the market; they use a combination of several technologies such as sub micron filtration, carbon filtration and ion exchange to give you 99.9% pure and clean water.
The three constraints to look out for when buying a water purifier:
1. Like for all other purchases, your budget will often be the deciding factor when purchasing a water purifier. If you only have a small amount to dispense, you should opt for a filtration system that is not particularly complex and can be installed manually without enlisting the help of a professional. On the other a water ionizer is expensive albeit the health benefits of drinking ionized alkaline water make up for every penny that you spend to buy the filtration system.
2. The size of your family is the second factor that should be considered, if you have a small two of three member family, you may not want to spend a lot. On the other hand, a comprehensive filtration system will be more appropriate for a large family or a busy office.
3. Determine your filtration needs, usually you can use a normal filtration system for the tap water on most towns and cities; however if you are not using the public system as your water source, you may need a filtration system that removes more than just the run of the mill contaminants such as lead and chlorine.
