Water is essential for human survival, but the quality of the water we consume is equally important as its quantity. Water can contain impurities like bacteria, viruses, chemicals, and heavy metals that can pose a threat to our health. To ensure the purity of the water we consume, water purifier have become indispensable appliances in our homes. In this article, we will discuss everything you need to know about water purifiers, including their types, working principles, advantages, and disadvantages.
Types of Water Purifiers
Water purifiers are available in different types, each with its unique advantages and disadvantages. The most common types of water purifiers are:
Gravity-based Water Purifier
Gravity-based water purifiers are the most affordable and straightforward type of water purifier. They do not require electricity to operate and rely on the force of gravity to filter water. These purifiers use a combination of sediment filters and activated carbon filters to remove physical impurities, chlorine, and volatile organic compounds (VOCs) from the water. However, they are not effective against dissolved impurities like heavy metals and salts.
Reverse Osmosis (RO) Water Purifier
Reverse Osmosis (RO) water purifiers are the most popular type of water purifier. They use a semi-permeable membrane to remove dissolved impurities like salts, heavy metals, and bacteria from the water. The RO water purifier also comes with pre-filters like sediment filters and activated carbon filters that remove physical impurities and chlorine from the water. However, RO water purifiers are wasteful, as they reject a significant amount of water during the purification process.
Ultrafiltration (UF) Water Purifier
Ultrafiltration (UF) water purifiers work similarly to RO water purifiers, but they use a membrane with larger pores that can remove physical impurities and bacteria from the water. UF water purifiers do not require electricity and are suitable for areas with low TDS (total dissolved solids) levels.
Ultraviolet (UV) Water Purifier
Ultraviolet (UV) water purifiers use UV rays to kill bacteria, viruses, and other microorganisms present in the water. UV water purifiers do not remove physical impurities or dissolved impurities from the water and are suitable for areas with low TDS levels.
Activated Carbon Water Purifier
Activated Carbon water purifiers use activated carbon to remove physical impurities and chlorine from the water. They are not effective against dissolved impurities like heavy metals and salts.
Features to consider when buying a water purifier
When buying a water purifier, it is essential to consider the following features:
The quality of water in your area will determine the type of water purifier you need. If the TDS levels are high, you may need an RO purifier. If the TDS levels are low, you can opt for a gravity-based purifier.
The storage capacity of the water purifier will depend on the size of your family and your daily water consumption. It is essential to choose a purifier with adequate storage capacity.
Benefits of Using a Water Purifier
There are several benefits of using a water purifier. Some of these benefits are:
Removes Harmful Substances
A water purifier can remove harmful substances such as bacteria, viruses, chemicals, and other impurities from the water. This ensures that the water is safe and clean for consumption.
Improves the Taste of Water
Water purifier not only removes impurities but also improve the taste of water. This is because the purifiers remove the chlorine and other chemicals used to treat water, which can affect the taste of water.
Using a water purifier can save money in the long run. Instead of buying bottled water, you can purify the tap water and save money.
Using a water purifier is environmentally friendly as it reduces the need for plastic water bottles. This helps to reduce plastic waste and is good for the environment.
Easy to Use
Water purifiers are easy to use and require minimal maintenance. Most purifiers have an indicator that lets you know when the filter needs to be changed.
In conclusion, having access to clean and safe drinking water is crucial for our health and well-being. Investing in a reliable water purifier is the best way to ensure that you and your family have access to clean and safe drinking water at all times. With the variety of water purifiers available in the market, it can be overwhelming to choose the right one for your home. However, by considering the factors mentioned in this article, you can make an informed decision and choose the right water purifier for your home.
