Well, water purifier has become a necessity for every household nowadays. And why shouldn’t, when the main water source, that is rivers, have become so polluted and dangerous to drink from directly. Although the government is leaving no stone unturned in working to clean our holy rivers, this problem will still take years to solve.
So here comes water purifiers, the immediate solution for Indian households. Now there are several types of water purifiers available in the market today. And before buying a water purifier, you must know certain things so that you can choose the most suitable type for your home.
Types of Water Purifiers | Which Water Purifier Is Best
RO water purifiers come with a semi-permeable membrane to ensure the goodness of drinking water. It has a water pump that pushes the raw hard water to pass through the RO membrane where it gets filtered as the RO barrier traps all the dirt and dissolved impurities like lead, fluorides, chlorine, arsenic, nitrates, and sulfates. As a result, we get purified clean water to drink.
If you receive a hard water supply, then RO purifiers are your best option. They are ideal for treating hard water. Even microorganisms present in the water that can affect your family’s health can be treated easily by an RO purifier. If you get bad-smelling water, RO purifiers are efficient in dealing with that too.
Normally, you will find two types of RO water purifiers. Tabletop RO purifiers can be mounted on a wall using support, and Under Counter, RO purifiers can be placed under the kitchen sink. Both of them work equally well.
While we have seen all the advantages of using RO water purifiers, there are some downsides too. A major downside is that it runs on electricity, so your household bill may shoot up. Moreover, when getting rid of chemicals and microorganisms, the RO purifiers waste a lot of water
This is a new and proven technology which rids drinking water from harmful microorganisms without using any kind of chemical. Yes, it is an environment-friendly water purifier. It has a UV lamp tube that produces UV light when water flows through it. When running water is exposed to UV light, even the deadliest and smallest microorganisms die. If a few of them survive this, their potency surely gets reduced because of the UV light.
UV water purifiers are ideal for treating low TDS(Total Dissolved Solids) water such as lakes and river water. They are incapable of treating hard water so the homes which have an abundance of chemicals present in their water sources won’t find the UV water purifiers useful.
The amazing thing about UV water purifiers is that they need minimal maintenance. You only have to replace the UV tube once a year if it stops working efficiently. These purifiers are so easy to operate, and unlike the RO purifiers who improve the water by using chemicals, UV does not make any changes to the water.
Although the UV purifier kills all the germs, their dead bodies remain in the resultant water. And it also is incapable of improving the water taste. The major disadvantage of UV is that it cannot treat muddy or turbid water.
The UF water purifier uses a somewhat similar concept as an RO purifier to clean the water. It uses hollow fibers of a membrane which prevents all the solid substances from passing through it. Large particles like debris, bacteria and virus sticks and suspended solids get trapped in the membrane.
UF water purifier is generally not ideal for all sorts of homes. Like if you are facing the issue of hard water, then a UF purifier is not suggested. While the RO purifiers can treat even minute particles, a UF purifier concerns a little bit larger impurities. So UF water purifiers are ideal for homes that have lowly contaminated water.
The UF purifiers do not depend on electricity. Moreover, they are long-lasting and can run for several years without adding to the repair costs that usually other water purification technologies expect. Although you will have to clean the UF membrane almost on a daily basis to prevent any kind of unwanted build-up.
4) The Sediment Filter
The sediment filter is not an option on its own. It is a pre-filter that can be used along with other water purifiers like RO and UV. Sediment is actually the matter collected at the bottom of water or any other liquid. It can be anything, such as particles of sand or mud, rust flakes of metal pipes, etc. So basically, the sediment filter removes the turbidity of water by catching these sediments. So you do not have to worry about large pollutants and visibly suspended particles in your water.
Most of these sediment filters are made from polyester and cotton fibers in India. When the raw water passes through the sediment filter via its water inlet, all the dirt and dust particles get trapped in it. The water outlet is then connected to RO or UV purifier as their water inlet.
If you wish to choose an RO water purifier, the sediment filter will increase the life of the RO membrane by removing the large particles from the water before even entering the membrane. If your water source is clean or is treated by a municipality before reaching your home, you do not need a sediment filter.
In this technique, gravity is used to purify water. Often, the gravity-based water purifier comes clubbed with activated charcoal or sometimes even UF type filtration membrane to get rid of all the impurities and pollutants. The gravity-based water purifiers are effective in treating water and also capable of eliminating debris with the help of a fiber mesh.
The biggest advantage of using Gravity-based water purifiers is that they do not run on electricity. So they can save a lot of money as well as energy. However, the downside of using gravity-based water purifiers is that they are incapable of treating disease-causing microorganisms present in water sources. So these type of water purifiers is suitable for those homes which are fortunate enough to be already availing soft and comparatively clean water.
We all know that a lot of minerals are found naturally in water which is important for the human body. But drinking an excess of those minerals can invite various diseases in your body. So a good water purifier takes care of that. It removes the excess salts, suspended impurities, and chemicals from the water, and present you with clean water for you and your family’s good health.
So now, we think you have got the idea of which water purifier is best for your home. Having a water purifier has become a must for everyone who cares about their and their family’s health. Although there are several advantages of bringing a water purifier home if you are from India, there are some conditions too which you need to keep in mind such as the maintenance cost, installation, filtration process, etc. Therefore, we hope this article helped you buy the most suitable water purifier for your home.
