Everyday different companies come out with different types of water purifying technologies. So it’s a bit tough to choose from them. There are certain things one should check before buying a water purifier.
What is water purification?
Water purification is the process of eliminating harmful chemicals, biological contaminants, suspended particles, and gases from water. The idea is to provide water that may be used for many purposes.
Although the majority of water is cleansed and sterilized for human utilization (drinking water), it can also be utilized for medicinal, pharmaceutical, chemical, and industrial reasons.
Throughout history, water has been purified in a variety of methods. Filtration, sedimentation, and distillation are used physically; biological processes such as slow sand filters or biologically active carbon are used biologically; chemical processes such as flocculation and chlorination are used chemically; and electromagnetic radiation such as ultraviolet light is used electromagnetically.
Things to remember when buying a water filter
A high-quality water filter is critical for filtering and maintaining the quality of your water. Many people, on the other hand, have no clue what a good water filter is. As a result, they find up purchasing low-quality goods and in most cases it doesn’t even work properly.
So here are few steps you need to remember when buying water filter-
Filter type
In today's global world, there are a plethora of models that claim to properly filter water. The purification mechanism, on the other hand, is dependent entirely on the filter types.
The typical and very inexpensive types are mostly carbon filters that categorise lead, chlorine, and mercury. However, if you want a higher-quality filter, you can attach your home water supply to a filtration system that works automatically.
Carbon filter might not be the only solution
If you want to drink the best water possible, a carbon filter isn't the appropriate choice. This type of filter might not be able to get rid of all germs or dust.
Carbon filters aren't able to remove arsenic, hexavalent chromium etc. Therefore, you are suggested to choose a reverse osmosis filter.
Checking the water quality
Determine the source of your tap water and get it tested for hardness, salinity, and TDS (Total Dissolved Solids). Based on your TDS level, you can choose the right kind of water purifier for your home
