Key Factors To Consider While Buying The Best RO Water Purifier For Home

Although there are many factors that you should consider while buying a water purifier, as mentioned in this buying guide, here are the things that you need to keep in mind before you are heading to the store for a RO water purifier.

back to menu ↑

Purpose & Type

Do you really need a water purifier? If yes, what types of water purifiers you need? You need to answer these questions first before you buy a water purifier. For example, if the TDS level of your tap water is above 300 PPM, you don’t even need a RO water purifier.

If you are getting processed drinking water, then you may not even need a water purifier. So you need to evaluate the requirement first before you decide which one you want to buy,

back to menu ↑

Tank Capacity

The tank capacity you can decide based on the family size. 5-8 liters water purifier is more than enough for a small family. However, if you have a joint big family, then the story is different.

back to menu ↑

Installation Type

Many models now come with tabletop installation features. So if you have short of space, then you should look for a portable tabletop water purifier that you can move around if you need. However, the wall hanging is the best as per my personal experience.

back to menu ↑

Special Features

See, most of the models with RO+UV+UF technology come with 7 stage filtration and other essential features.

But how about a TDS controller, mineralizer, a LED display, or dual dispensers. These are additional features that add value to a product. So if you are spending money on a product, you should also look for the value that it adds.

back to menu ↑

After-Sales service

A water purifier is a machine, and every machine can break down. So always buy from a brand that offers good after-sales service. Otherwise, the running cost will be very high.

back to menu ↑

Price

Personally, I don’t compromise on quality for the price, especially when it comes to our health and safety. But it does not mean that we waste our money on anything. Just evaluate the price against the feature that it offers. If the price is justified, then there is nothing wrong with investing money in a costly water purifier.

A couple of models reviewed in this article may have the price mentioned on them. Please note that these prices are subject to change due to fluctuating pricing on Amazon. Readers should always check the latest price on Amazon before purchasing.

Key Features

This is one of the few models that have the option of a hot water dispenser. It has two different temperature settings for hot water, one is for drinking, and another is for cooking. In this Covid situation, getting hot water instantly is excellent.

Due to the hot water and the normal water, it has two different dispensers. With the touch of a button, you will get instant hot water and normal water. The hot water you can use for normal consumption or for making tea and coffee.

Unlike other RO+UV+UF water purifiers, this model comes with 8 stage filtration process involving ART technology and Mineralizer technology.

The ART technology (Advance Recovery Technology) can recover more clean water from the dirty water, which means that you will have less water wastage.

The mineralizer technology adds minerals to keep the mineral level stable after purification. It also adds some chemicals so that the Ph level remains in the specified range. Both the Ph level and minerals are equally important for our good health.

The nigh assist function is something unique to this model. At night, if you need water, you don’t need to switch on the light in your kitchen. Instead, the night assist feature will guide you to locate the water purifier. The LEDs used in the night assist feature consume very little power. Although this feature may be unnecessary for many consumers, this is good to have feature.

Do you know that this particular RO water purifier comes with Silver Charged Membrane Technology ( SCMT), which is the second level of protection for water? It removes any potential secondary microbial contamination post RO purification. A double layer of protection means more pure water.

LG never disappoints with features, and this water purifier is no different too. This is one of the very few water purifiers that have a stainless steel tank.

Stainless steel tanks are way better than plastic tanks because of the build quality, less chemical reaction, and less pathogen growth.

Unlike other water purifiers, this LG RO water purifier has 8 stage filtration process. The multi-stage filtration can remove particles as small as .0001 micrometers. Forget about viruses and bacteria, as this water purifier can easily remove those.

Once the water is purified and kept in the tank, this water purifier emits UV radiation every 6 hours so that there is no bacteria formation. This feature can not be found in any water purifiers in India.

This model also has a mineral booster that adds essential minerals so that the water tastes good and safe too. It also adds magnesium and calcium, which are essential for bone growth.

One of the main issues with many RO water purifiers is that they waste a lot of water. However, this model waste only 50% water. That means for one liter of pure water, 500 ml of water will be wasted.

This is one of the water purifiers that comes with a special dispenser for washing fruits and vegetables. I can understand that many of us may not need to wash vegetables with pure water, but this model has this feature in case you need it.

Coming to the installation, you can wall-mount it or keep it on a table. That adds a nice convenience. You can easily operate this machine with its intuitive LED display, which is also one of the major highlights of this water purifier.

This is one of the few models with 10 liters of capacity, which is ideal for large families. It has digital control panels that show the TDS level of water. This RO water purifier can clean water up to 2000 PPM TDS levels. Normally in our tap water, we don’t get water above 1200 PPM TDS level.

The 7 stage filtration is a generic feature of all RO+UV+UF water purifiers, and this model is no different. But this model has a purity lock feature that stops the water flow all together when the cartridge is expired. So you won’t get even a single drop of non-purified water.

It also has a soft touch button for water dispensation. Although it is good to have features, personally, I am not a fan of that button as it seems very fragile.

The feature that I like most is that you can keep this water purifier on a table also. So no need to hang it on the wall unless you need it. This is something small families or bachelors love.
