Best water purifier for home in India [May 2022]: Editors’ picks for top RO, UV, UF, water purifiers right now

Water purifiers play a vital role in our daily lives. With potable water of essence and heatwave alerts being issued for a number of states, staying hydrated and with good water is extremely important. In India, where, tap water is not the safest and water from natural sources like rivers and lakes can get contaminated with human, plant, animal, and industrial waste, a water purifier becomes a must-have device. With a water purifier at home, you instantly get access to safe and drinkable water, in other words, potable water.

Around the country, the local authorities like municipalities add chlorine or fluorine to the groundwater. This is done in order to get rid of viruses and bacteria. While the local authorities do their best, it is often not enough to get rid of all the harmful chemicals or contaminants in the water. So, it is better to get yourself a water purifier and these days, they come with a combination of UV, UF filters, and RO (reverse osmosis). So, here is how to choose the best one.

Best water purifier brands in India (May 2022)

As mentioned earlier, there are a number of brands that sell water purifiers in India. These brands differentiate their products on the basis of features offered with each of these models. The decision to choose the right water purifier boils down to factors such as TDS level of water supplied in your area and type of water purification system. Depending on these factors, here are some of the best water purifier brands in India.

8 things to keep in mind before buying a water purifier

While one might think that buying a water purifier is as simple as going to an e-commerce platform, selecting the brand that you like and placing the order, the reality is there are many factors to consider before you select the right water purifier for your home.

These factors also vary from region to region, which should further change your preference. Then there is, of course, the marketing mumbo jumbo that does not help much. With that in context, here are eight things that you must keep in mind before you go ahead and buy a water purifier for your home.

Water Quality

This is the most important thing that you need to check before deciding the water purifier for your home. The water supplied to your home is likely to be hard water, which means it has a high amount of TDS or Total Dissolved Solids. The TDS is a measure of the dissolved combined content of all organic and inorganic substances present in a liquid. This could be in molecular, ionised or micro-granular suspended form. The WHO recommends a permissible limit of TDS between 50-120 PPM and pH above 7.4 in potable water.

The inorganic salts contained include calcium, magnesium, potassium, sodium, bicarbonates, chlorides and sulphates. To get rid of these inorganic compounds, companies use a process known as RO or reverse-osmosis. This uses a semi-permeable membrane measuring 0.0005 micron in size and they make it impossible to stay in the water. If the water in your home has high TDS then an RO water purifier would be a good choice.

Water Pressure

Another factor that will help determine the right filter for your water purifier is water pressure. A reverse osmosis water purifier system will work well when you have high water pressure. A pressure of 5 to 40 pounds per square inch or psi is recommended for such a system. For those homes with low water pressure, companies recommend using a booster pump attachment to the RO system. If your water supply has low TDS, you can also opt for an activated carbon filter.

Contamination

The second factor to consider while shopping for a new water purifier is contamination. By contamination, we are referring to the presence of heavy metals such as lead, arsenic, magnesium, copper and iron. In large amounts, these heavy metals can become toxic. The industrial waste is often cited as the source for the presence of heavy metals in your water.

While RO can get rid of inorganic compounds and even heavy metals, you will need a specialised filter to eliminate germs and other microorganisms. A water purifier with ultraviolet (UV) filter can not only disinfect the water but also restrict harmful microorganisms from multiplying in the water source. They use an UV lamp to achieve this and you can also look for an UV filter with an ultra-filter to remove suspended bacteria. This is best when the water supply is free from total dissolved solids.

Daily Usage

Another factor to consider is average daily consumption of water for your family. The first thing you need to decide is whether you need a purifier only for drinking purposes or for the entire house. Once you know the requirement, you need to figure out consumption. If your daily water consumption is high, you will need to buy a model with high power and high output rate. As a thumb rule, it is recommended that the output of a water purifier in one hour should not be less than the number of people in your home.

Portability

This may not be something that comes to your mind when you buy a water purifier. However, it is a critical aspect since a water purifier is something you buy once every 8 to 10 years. If you are relocating to a new place, you won’t need to buy a new water purifier, and instead you’ll be moving your existing water purifier. So, you must look at the body of a water purifier including its portability and weight. Also a good looking water purifier is an added bonus, and might even add to your kitchen aesthetics.

Electricity

A number of water purifiers don’t work without electricity, which makes it bad for areas with constant power cuts. An UV filter won’t work if you don’t have electricity since it uses electricity for the UV lamp to work. Similarly, an RO system uses electric power to activate the RO membrane. But a system with activated carbon filters or an ultra filter will work without electricity, but they will only be able to eliminate sediments from your water source.

Budget

Once you know your consumption and kind of purification technology you are looking for, it is worth setting a budget. A water purifier is not a smartphone that you will upgrade once every year or two. It is a long-term investment that will require a similar budget. So, we would recommend going for a trustworthy brand. With the reliability and kind of filter that you plan to get, you will find yourself spending at least Rs 7,000 – Rs 8,000 on a water purifier. The cost will increase if you go for a RO water purifier (more on this later).

Maintenance cost

A water purifier is a household appliance and with that comes the maintenance cost. The maintenance includes changing the filter and servicing the entire system. So, you need to consider the cost of servicing the device once every three or four months. On top of that, you will need to replace the filter once every year. A good purifier generally comes with a maintenance cost of around Rs 2,000 per year but they can go as high as Rs 5,000. Some companies also offer annual maintenance contracts that might be cheaper in the long run.
