There is no one substance that is more important to man than water. After all, water does make up more than two-thirds of the human body. Water, then, is essential in every possible way. In fact, people won’t survive without it. Unfortunately, there’s no telling just how unsafe the world’s water sources now are, given the extensive threat of water pollution. Now, a clean water supply is quite elusive, and this is why water purifiers and filters exist.
Why invest in one?
Water is clear and transparent; how much dirt could there be? Well, you’ll be surprised at how much dirt and chemicals are lurking in your water supply. Even though these chemicals are not directly dangerous especially since they appear in very small amounts anyway, they can still pose quite a threat given that we use water every day and even consume a lot of it on a daily basis. So to ensure your safety and that of your family, getting a water purifier makes a highly worthy investment.
What are you in danger of?
If you’re still skeptic, perhaps a list would be more convincing. According to countless studies, various water supply systems all over the world have listed contaminants ranging from lead, pesticides, cysts, viruses, bacteria, to pharmaceutical drugs. Just imagine what all these can do to your health if you are exposed to them regularly through the water you use and drink.
To protect yourself, you need a purifier. The basic concept behind purifiers is filtration. This is the simple process of filtering, or sifting out, any contaminants in the supply to make the water safe and clean. Water purifier filters revolve around the use of the filter itself, which is a material that separates the clean water from the contaminants when the water passes through it. Different materials can filter out contaminants in different ways. For example, reverse osmosis uses a semi-permeable membrane as a filter, while an activated carbon water filter uses either a block of carbon or granulated carbon.
Behind the scenes
Nowadays there are newer methods of purification that does not make use of an actual filter that the water goes through. For example, there are UV or Ultraviolet water purifiers that just expose the water to UV light in order to kill germs and other contaminants.
Some drawbacks to consider
Most filter systems rely mainly on gravity so that the water will go through the filter, although purifier filters that do not have any special mechanism to push water through at a much faster rate usually produce water more slowly. This can be a problem especially in large households that need a lot of water.
Aside from that, almost all filter systems require you to replace the main filter every six months. You can, however, look for some purifier filter that can go for as long as one year without replacement. But to ensure the effectiveness of the filter, make sure you replace the filter when needed.
