A lot of people use the terms water purifiers and water filters interchangeably without knowing the actual meaning of these terms. If you are one of them, please spare a few minutes and read this article fully. I am here to explain the fundamental difference between purifiers and filters and why they should not be considered one and the same.
Water filters, as the name suggests, are based on the process of filtration. They have different types of filters which filter out the contaminants present in water. Some of the most commonly used filters include carbon filters, iron filters, and sediment filters. When water passes through the porous filter, several contaminants including large sized bacteria, protozoa, parasites, dirt, and grime are removed and the water you get is relatively pure and safe to drink.
Water purifiers, on the other hand, are based on the process of purification. They literally purify water – they separate the water molecules from the contaminants present in water and give you pure water. There are several methods of purification including reverse osmosis, distillation, and ion exchange. The water that comes out of a purifier is free of pathogens, microbiological organisms, and viruses.
Now let us take a look at the differences between these two.
1. Filters do not remove the viruses present in water. This is a major disadvantage when it comes to filters. There are some extremely dangerous viruses present in tap water – hepatitis A is a very good example – and it is very risky to drink it without getting rid of them. Purifiers, on the other hand, are capable of removing these viruses present in water.
2. Purifiers remove the bad odor and bad taste associated with contaminated water. As a result, the water you get is not only pure and safe to drink, but also tastes and smells good. Filters, on the other hand, are not capable of that.
3. Most water filters cannot filter out the contaminants that are extremely small in size. Unless they have a submicron filter, they cannot get rid of a lot of contaminants present in tap water that are smaller than even water molecules in size. It is important to note that most of the highly dangerous viruses present in water are extremely small in size. They can easily pass through filters. Purifiers, conversely, usually do an extremely good job of removing such contaminants.
As you can see, there are lots of differences between purifiers and filters. Though they are used for the same purpose – purification of drinking water – they are not equally effective. If you want to make sure the water you drink is absolutely pure and safe to drink, you should go for water purifiers.
Make sure the purifier you buy meets the standards set by the EPA Guide Standard Protocol for Microbiological Purifiers. They can be a bit on the expensive side, but, as far as I am concerned, it is worth paying the money. So, think about the pros and cons of filters and purifiers and make the right decision today.
