Without clean and safe water, humans cannot live peacefully since water contamination is the reason for many diseases in India. So, now water purifier is necessary for every home and office. Selecting the best water purifier is not an easy task as there are many water purifier models available in the market.
Everyday many advertisements appear on TVs, magazines, and newspapers, and all the water purifier brands promise to provide you the pure drinking water, making us more confused about which water purifier is best. It can directly affect your family’s health and well-being if you do not choose the right water purifier.
Water Purifier Buying Guide
Firstly, you should know about some of the basic terms of water purification systems.
Types of water purifier technology
Water purifiers available in the market are mainly based on three kinds of purification technology:
RO (Reverse Osmosis) Purifiers:
For water containing a high level of salts and make it unfit for drinking, RO (Reverse Osmosis) is a widely used technology to purify water. RO water purifiers can remove all dissolved impurities from water, such as heavy metals, chemicals, and dissolved salts. This form of water purification involves filtering out a selected number of water contaminants depending on their size, forcing water through a semi-permeable membrane. This technique requires electricity to purify water and produce lots of wastage water.
UV (Ultra Violet) Purifiers:
UV water purifiers use the ultraviolet filtration process to kills germs, bacteria, viruses, and other microbes. Germs and viruses are eliminated using ultra-violet radiation are made to pass through water. However, UV filtration doesn’t remove all dissolved impurities from water. This method also requires electricity but does not generate wastage of water. If your supplied water does not contain any dissolved impurities, you can choose a UV water purifier.
UF (Ultra Filtration) Purifiers:
This technology removes germs and bacteria from the water. UF purifiers purify water with the help of an ultra-filtration membrane. This purifier does not allow bacteria, viruses, and germs to pass through it even though the UF membrane’s gap size is larger than the RO membrane. It does not use electricity in the filtration process. But, UF Filters doesn’t remove dissolved salts and heavy metals from water.
You can also get water purifiers with a combination of all these technologies like RO + UV or RO + UF or RO + UV + UF water purifiers, which are more effective than water purifiers using a unique technology.
Things to check before purchasing a water purifier
TDS Level of Drinking Water
Before drinking, many dissolved salts, impurities should be removed. TDS levels measure the quantity of dissolved salt and heavy metals like lead, arsenic, mercury present in water. But, the thing is how to check the TDS level? In the market, TDS meters are available, which helps to measure the TDS level of drinking water. Depending upon the TDS level of water, you can choose the suitable water purifier for your home. More the TDS level, the less the water is harmful to drink.
Storage
You should opt for a water purifier with higher storage capacity if you are residing in an area where there are recurring power cuts. A high storage capacity water purifier ensures that you have access to safe and clean water even without electricity. An ideal optimal water purifier has a storage capacity of 7-8 liters.
Maintenance and after-sales Service
The water purifiers need regular maintenance after every 3-4 months to function smoothly. For the brand that you have selected, it is necessary to check the quality of services provided after-sales. Always go for a reliable Water Purifier brand that offers high-quality customer support.
Installation and Warranty
Almost all the reputed brands provide free installation and one year of warranty. Before purchasing the water purifier, you need to check the warranty and installation details. The reason is many companies may charge some extra amount for the installation process.
