Recently there was a programme on the National Geographic channel. The programme was about the amount of drinking water left on the earth. The takeaways from the programme were as follows.
Now, how much of this 1% is pure? The answer can surprise you that minuscule portions, maybe the streams that originate from the glaciers are pure enough to drink directly.
A massive majority of water needs purification. Hence, you have various methods of purifying drinking water of which the use of water purifiers at home is one of them.
Let us see the various methods employed by these water purifiers, especially the advanced ones like the Blue Star Aristo RO UV water purifiers.
Most of the water purifiers available in the market use the six-stage or seven-stage purification process. Let us briefly glance through the process before proceeding with reviewing the Blue Star water purifier.
The impurities can be large or small. The municipal authorities take care of the significant pollutants before pumping them to our homes. However, the water can collect contaminants in the form of dirt and rust from the pipes, moss from the storage tanks, and so on. These impurities can interfere with the RO and UV water purifying process. Hence, you have the sediment filter to eliminate these contaminants before they enter the appliance.
The water we receive from the municipality or the wells contains organic impurities that can easily pass through the sediment filters. These organic chemicals can give out a putrid odour. The activated carbon filters can remove these impurities so that the water that goes into the RO membrane becomes relatively pure.
Water contains TDS (Total Dissolved Salts), and heavy impurities like arsenic, mercury, and lead. The source water can also contain nitrates, sulphates, and carbonates and so on. The groundwater contains traces of pesticides. The Reverse osmosis process is the best procedure to eliminate these impurities.
This process involves the passing of water through a reverse osmosis membrane at high pressure so that the pollutants get trapped in the membrane resulting in the supply of pure water. However, this system wastes a lot of water in washing out the impurities. There are ways to use this wastewater as well. We shall look into these aspects at a later stage.
In spite of the RO filtration, minute impurities having a molecular weight of less than 20 can still sneak into the pure water. The Ultra Filtration membrane ensures to eliminate these minute contaminants to ensure the unlimited supply of pure water.
Ultra Violet Chamber
The pure water that comes out of the RO and UF purification systems could still contain bacteria and viruses small enough to escape attention. The radiation from the UV lamp kills these bacteria and viruses making the resultant water germ-free.
The RO purification process removes the TDS from the water. In the bargain, it also eliminates the essential minerals like calcium, magnesium, and so on. Hence, the pH level of the pure water comes as close to 7 as possible. Such water though pure does not have any taste. Accordingly, the water purifier manufacturers use mineralisers to replenish the lost minerals and enhance the taste of the water.
The Post Carbon filters
Some of the water purifiers employ an additional level of filtration known as the Post Activated carbon filtration. It is to remove the traces of the volatile organic compounds that tend to affect the taste of drinking water.
We have seen the seven essential stages of water filtration. The Blue Star Aristo RO UV water purifier uses the 6-stage filtration process. Let us now look at the salient features of this water purifier.

Blue Star Aristo RO UV Water Purifier – Review
Purifying water before drinking it has become inevitable today because of the spread of water-borne diseases like jaundice, typhoid, and so on.
As we tap into the deeper reserves for meeting our drinking water requirements, there is a higher level of contamination through TDS and other salts. Therefore, a high-quality water filter has become a necessity in every home. Here are the essential features of the Blue Star Aristo RO UV water purifier.
Blue Star has a reputation in the water purifier manufacturing industry. It manufactures some of the best water purifiers of which the Aristo is one.
This water purifier uses a 6-stage water purification method that includes the following.
Aqua Taste Booster
The RO process removes the TDS and other harmful salts like lead, arsenic, and mercury. In the process, it also eliminates essential nitrates, sulphates, and carbonates. The Aqua Taste Booster replenishes these salts and maintains the pH level of water.
The Blue Star Aristo water purifier comes with a double-layered RO and UV protection. Therefore, the resultant pure water is not only free of TDS and other harmful salts but also is germ-free. The UV protection features kill the bacteria and other microorganisms like viruses and cysts.
Copper Impregnated Activated Carbon
This appliance has copper impregnated activated carbon filter. The advantage of having copper is that copper is a renowned anti-bacterial agent. Therefore, you get additional protection from bacteria and viruses.
Other notable features
- The large 10-incl filter ensures an efficient purification process
- The device comes with a large storage tank with a capacity of seven litres.
- The child lock is a safety feature that prevents your child from wasting water unnecessarily.
- This system has a purification-on display that indicates the purification process is in progress.
- The tank-full indicator is useful as it highlights when the storage tank becomes full.
- There is an advanced feature known as the low-pressure alert to indicate that the input pressure of the source water is low.
- The water purifier comes with a UV fail alert to warn whenever there is a UV lamp failure.

Blue Star Aristo Review – Final Words
In these days of heavy industrialisation, you do not get pure water from the natural water bodies. The shrinking groundwater resources also result in the groundwater containing a high proportion of TDS. The use of an effective water purifier like the Blue Star Aristo RO UV water purifier is more of a necessity than a luxury.
