Water purifiers that use RO, UV or a combination of both allow the water to pass through certain stages of purification. The sediment filter acts as a pre-filter that removes mud, coarse particles, and dust from the water while the activated carbon removes odor and excess chlorine from the water.
You will understand more if you go through the working of UV water purifiers, working of RO water purifiers and the working of RO+UV water purifiers. You can also go through the types of multi-stage water purifiers like RO+UV+UF and RO+UF.
Another popular nonelectric water purifier is the gravity-based water purifier. They are divided into two types- gravity-based candle filter purifiers and gravity-based filters with chemical capsules. They both use the mechanism of gravity for the purification process.
Buyer’s Guide For Water Purifiers
Water Purifiers allow the water through different stages of purification to purify the water. There are water purifiers that use RO Water Purifiers to treat water that is hard with high levels of TDS or UV Water Purifiers to treat water with low levels of TDS and a high level of disease-causing micro-organisms. Water purifiers also use a combination of both RO+UV Water Purifier to purify hard water with high levels of germs and bacteria.
Several multi-stage water purifiers like RO+UV+UF, UV+UF, and RO+UF are also useful in treating water from multiple sources. Thus, before purchasing a water purifier, you need to test the quality of water supplied to your home. You can then choose the water purifier with the ideal purification technology.
Filter and Cartridge
It is essential to ensure that the water purifier you purchase comes with sediment and activated carbon as pre and post-filters. The sediment filter removes the coarse particles, dust, and dirt from the water while the activated carbon which has anti-bacterial properties is essential in removing the smell and volatile components.
A Biotron cartridge is an added advantage as it breaks down the molecules of the water and allows you to enjoy the goodness and nutrients of the water quickly. On the other hand, a mineral cartridge is essential as it not only retains the essential minerals; it also enhances the taste and maintains the pH of the water.
Choose a water purifier after understanding the drinking water requirement as per the size of your family. The purification capacity of 12-15 liters per hour is ideal for a small or average family, while that of 60 liters per hour is perfect for a big family. The purification capacity should be enough to provide your family with healthy and safe drinking water that is free from all contaminants.
Storage Capacity and Tank Type
Most UV water purifiers do not come with storage tanks so that you are always provided with fresh drinking water. However, RO and even gravitation based water purifiers come with a storage tank. This allows you to have access to purified water at all times. Thus, it is necessary to ensure that the storage capacity of the tank is at least 7-12 liters, which are enough for you and your family.
Apart from this ensure that the tank is made up of ABS food-grade plastic or stainless steel so that the water is kept safe. A protection cover is also required to keep the stored water free from insects and dust.
Indicators and alerts
A UV fail alert notifies you when it is time to change the UV lamp while filter change alerts notify you when you need to change the filters. It is also beneficial for the purifier to have features such as purification-on and full tank indicators. The purification on indicator notifies you about the purification process while the full tank indicator allows you to know when the tank is full.
Warranty and after-sales service
It is essential that you choose a brand that offers the best guarantee of the product with excellent after-sales service. The minimum warranty of the product should be for one year. Certain brands such as Kent provide a 1-year warranty plus three years of free service.
You can go for a water purifier that can be placed on the counter or mounted on the wall. The sleek and stylish designs blend perfectly well with the modern look of your kitchen. However, if you have space constraint, you can go for an under sink water purifier that remains hidden under the sink of your kitchen
Ensure that the brand you choose offers free installation of the purifier within 3-5 days of purchase. This prevents hassle and adds to the convenience of the buyer.
It is essential to ensure that there is no leakage and no water is wasted during the purification process. Certain features like child lock prevent wastage of water. This feature is essential since every drop of water counts.
Price is always an essential factor in every product purchase. Water purifiers are available in a different price range. If you have a restraint on the price, you can choose UV, UF, or gravitation based filters. Multi-stage purifiers like RO+UV and RO+UV+UF are available at a higher price.

Frequently Asked Questions
1. Why is it essential to remove harmful contaminants from the water?
Many harmful contaminants are present in the water. These include dissolved solids, rust, pesticides, disease-causing germs and bacteria and heavy metals such as arsenic, lead, iron, fluoride, etc. These contaminants are responsible for causing severe health issues like cholera, hepatitis, jaundice, typhoid, and even cancer.
These impurities affect the taste and smell of the water as well. Hence, it is important to remove these contaminants from the water, so that your family is provided with water that is free of any foul taste or smell as well as safe and healthy for consumption.
2. What is TDS?
TDS stands for Total Dissolved Solids. It refers to the metals, minerals, salts, cations, and anions that are dissolved in the water which are invisible to the naked eye. Its units are ppm (parts per million) or mg/l. The TDS of water can be measured using a TDS meter. Know why TDS controller is required in RO water purifier.
3. What is the acceptable TDS level of drinking water?
The lesser the TDS level, the safer is the water to consume. The average TDS level of the water that is recommended for drinking purposes should be 300-500 ppm. On the other hand, anything more than 1200 ppm is unfit for drinking purposes.
4. Is it necessary to test the water supply to our houses?
Every house does not obtain the same quality of water. The TDS levels and the contaminants can differ from place to place and house to house. It is very important to test the quality of water that is being supplied to your home to know the type of water purifier that is most suitable in removing these contaminants.
RO water purifiers are the best choices for areas with high TDS levels, while UV water purifiers are useful in killing the germs and bacteria that cause various water-borne diseases.
5. How often should you change filters?
Most filters which include pre and post-filters like sediment and activated carbon filters should be changed at least once every six months.
The membranes should be changed after every two years. Most water purifiers these days come with alerts and indicators like filter change alerts and UV fail alarm that notifies you when it is time to change the filter and cartridges.
6. What is the most suitable water purifier for borewell water?
Most houses in big cities are supplied water from underground or borewell. The water supplied from borewell consists of very high levels of TDS, rust, iron, lead, fluoride, etc. Hence, the best type of water purifier for this case is RO water purifiers that use reverse osmosis to remove the harmful contaminants through a semi-permeable membrane.
Borewell water also contains high levels of germs and bacteria that cause water-borne diseases. For this, the recommended water purifier is a RO+UV water purifier where the UV lamp is used to kill the disease-causing micro-organisms by attacking their DNA and preventing them from multiplying.
7. What is a universal water purifier?
Universal water purifiers are multi-stage water purifiers that use all the purification technologies like RO+UV+UF along with sediment and activated carbon filters. These water purifiers can treat water coming from multiple sources like borewell, mixed, tanker, or underground.
8. Which is better- RO or UV
UV water purifiers can only kill the disease-causing germs and bacteria. They fail to remove the bodies of these micro-organisms and other dissolved solids. On the other hand, RO water purifiers can remove all the contaminants and also eliminate the dead bodies of these micro-organisms.
Moreover, RO water purifiers can enhance the taste of water, and the mineral cartridge retains the essential minerals. They are perfect for areas with high TDS. Thus, even though RO is more expensive then other filters, it is a better option.
9. What is SCMT?
SCMT stands for Silver Charged Membrane Technology. It is a new stage of purification in RO water purifiers that prevents secondary microbial contamination. RO+SCMT offers double protection and purification that provides water that is both safe and healthy for drinking.
