In order to obtain clean and safe drinking water, you need to choose the right filter for the right water contaminants. Therefore, you need to make some research and find out what type of impurities and chemicals exist in your tap water. Giving that every water provider is required to show customers water quality reports, you should take advantage of this privilege and discover the pollutants that exist in your municipal water. Furthermore, based on your findings, you can start searching for a water filter system that was designed to eliminate the same type of contaminants that you deal with. Here are the main categories of water filters.
Although these types of water filters are very affordable, they come with high maintenance costs, as they require constant cartridge replacement, which can make them more expensive than other systems on the long term. Pitcher water filters integrate a Granulated Activated Charcoal which is not very solid, so they don’t have the capacity to eliminate all chemicals. Furthermore, they can make only a small difference in the quality of your water, as they can’t remove heavy metals, VOCs and fluoride. The only thing they can do is to improve the taste of the water by removing chlorine. So, if chlorine is your only problem, a pitcher water filter is what you are looking for.
Reverse Osmosis Systems are used to eliminate asbestos, arsenic, heavy metals, fluoride and chlorine. These water filters integrate a semipermeable membrane to remove pollutants, but they also reject a significant quantity of water during the filtration process. So, it can lead to a large waste of water. Another disappointment in this type of water filters is that it eliminates beneficial minerals from water, too. Therefore, it removes calcium, potassium, and magnesium while filtering water.
A water distillation system uses heat to turn water into steam. The technology that it uses ensures that the vapors circulate and get trapped in a cooling chamber, where they turn back into liquid, ensuring that contaminants stay behind. The distillation process eliminates pollutants like asbestos, bacteria, germs, arsenic, heavy metals and fluoride, but it can’t remove VOCs and endocrine disruptors. Keep in mind that these water filter systems can’t operate during a power outage and that they consume a considerable amount of energy to function.
According to the EPA, a Solid Block Carbon Filter is the best choice that people can make when they want to get rid of water pollutants like pesticides, VOCs, herbicides,chemicals, fluoride, salt, bacteria, nitrites, heavy metals, and parasites. Due to their high efficiency, these water filters can turn rain water and even pond water into safe drinking water. Furthermore, they are very affordable, and they don’t require expensive filter replacement. Another advantage of the Solid Block Carbon Filters is that they don’t need water pressure, nor electricity to operate.
The categories featured above refer mainly to the filtration process. However, there are also other categories that you mush consider. If you want a complete protection, choose a whole house water filter. If you only want to filter your drinking water, you have to choose between a counter-top filter, a faucet filter or an under-sink filter.
