What is Water Purification
The process of removing unwanted chemicals, biological pollutants, suspended particles, and gases from water is known as water purification. The goal is to provide water that is suitable for a variety of uses.
Although most water is cleaned and disinfected for human consumption (drinking water), it can also be used for a variety of other purposes, such as medicinal, pharmaceutical, chemical, and industrial uses.
Water cleansing has been done in a variety of ways throughout history. Physical procedures like filtration, sedimentation, and distillation are utilized; biological processes like slow sand filters or biologically active carbon are used; chemical processes like flocculation and chlorination are used, and electromagnetic radiation like ultraviolet light is used.
Defining a Water Purifier
Water filters and water purifiers might sound like the same product but there are some inherent differences. Water purifiers and water filters do the same thing: they remove pollutants from the water.
Water purifiers, on the other hand, take it one step further by destroying biological pollutants and removing minerals from the water. This is accomplished by a variety of purifying methods:
- UV Treatment
- Reverse osmosis (RO)
Types of Water Purifiers
There are several kinds of water purifiers available in the market. The prices vary according to quality and brands. Water purifiers are grouped into five categories based on the procedures used to purify the water:
Reverse Osmosis Water Purifier
To filter water, a RO water purifier employs a semipermeable membrane. The water is pumped through the RO membrane by a water pump, which pressurizes the raw hard water to allow it to pass through.
Dissolved solids such as arsenic, fluoride, lead, chlorine, nitrates, and sulfates are caught and adhered to in the RO membrane during this process, resulting in cleaned water.
UV Water Purifier
UV (ultraviolet) water purification is a proven technology that may remove disease-causing germs, pathogens including bacteria, viruses, and cysts in water. During the purifying process, this environmentally friendly method did not employ any chemicals. A UV water purifier is made out of a UV light tube through which water must pass to be purified. When running water is exposed to UV light, any microorganisms such as bacteria and viruses are destroyed and rendered inert. Germs from dead bodies remain in the water, but they are no longer hazardous.
Ultra-filtration (UF) Water Purifier
Ultrafiltration, or UF, uses hollow fibers in a membrane consisting of a thin layer of material capable of separating water from other particles in the water. When water passes across the UF membrane, suspended particulates, bacteria, and viruses adhere to the membrane, trapping them and retaining them.
Activated Carbon Water Purifier
Activated carbon is a type of carbon (coal, coconut shells, nutshells, and wood) that has been broken down into little bits. Activated carbon is usually generated from charcoal. Most pesticides and heavy metals that cause sickness in water are removed by activated carbon. Chemicals that make water taste and smell foul are removed by activated carbon. When it comes to removing chlorine from water, activated carbon is the most effective.

How To Choose the Best Water Purifier
With so many alternatives on the market, people are frequently perplexed when it comes to purchasing a water purifier for their homes. It is a significant decision since it affects the health and well-being of people’s families. There are a few things to consider when purchasing a water purifier.
Here is how you can choose the best water purifier:
Checking the Water Quality
Find out where your tap water is coming from and get it tested for hardness, salinity, and TDS (Total Dissolved Solids). If the TDS level is less than 500 ppm, the water is safe to drink; nevertheless, if the quantity of dissolved solids is greater than 1000 ppm, the water is dangerous and harmful. The first step in selecting the best water filter for your home is to determine the source of your tap water.
A variety of water purifiers are available, depending on the quality and source of the water. Water purification using RO (Reverse Osmosis) technology is best for water with a TDS level of more than 500ppm. RO technology purifies water by filtering heavy metals, particles, and minerals through selectively permeable membranes. If the TDS level is less than 200 ppm, UV (ultraviolet) filtering can be used to eliminate contaminants while keeping important minerals.
Determine the required capacity of your water purifier by analyzing your family’s daily water use. Purifiers with a large water storage capacity perform effectively in areas where electricity fluctuates frequently.
Enhanced security features
When shopping for a water purifier, seek features and functionality that are more advanced. Filters, for example, are an important aspect of water purification, but we frequently overuse them and end up drinking contaminated water. As a result, it’s critical to replace them as soon as they expire.
Service and Policy
Water is cleansed through numerous filters, which must be serviced and maintained regularly. When purchasing a water purifier, you should constantly consider the availability of service and the overall cost of maintenance.
Water purifiers are crucial appliances for every household. So, you should always be extra careful while buying one. Consider the aforementioned facts before purchasing a water purifier. You can do your research and read reviews online before deciding. Make sure to invest in the best water purifier because your health and wellbeing depend on it!
