    Except for the water purification process, all three variants are similar. Aristo has two color options, white and black. The price also varies based on the technology used.

    In this review, we will focus on the Blue Star Aristo RO+UV+UF as it combines the features of both RO+UV and RO+UF models. We recommend that you choose the Blue Star Aristo RO+UV+UF as the price difference is not significant between these variants.

    What is water purification, and what are the various methods of purifying water?

    Water in India

    This section of our post will help you understand the basic principles behind water purification.

    Water purification removes harmful chemicals, bacterias, and viruses, suspended solids, and gases to make it suitable for us to drink. The modern water purifiers are advanced, and they use innovative technology to make water fit for human consumption.

    Methods of purifying water

    Methods of water purification

    This section of our post details the various water purifying methodologies.

    Water boiling

    Boiling is the simplest and the most effective way to rid water of all harmful biological contaminants (bacteria and viruses). We at fourbloggers.com recommend that you boil drinking water before drinking, even if you use a water filter. Remember, boiling water does not remove chemical toxins and impurities.

    Distillation

    Distillation uses condensation to purify water. Boil the water and collect the water vapor through condensation to purify water. Distillation leaves behind harmful toxins.

    Reverse osmosis

    RO filters are quite popular in India. A RO filter uses pressure to force water through a semipermeable membrane. In other words, a device pushes water through a multi-layered filter. This filter traps and removes all the impurities.

    The downside to the RO process is wastage of water. In other words, if you filter 6 liters water, 4 liters are typically wasted. People generally use the unfiltered water out of the RO for non-drinking purposes, such as cleaning and laundry.

    Granular Activated Carbon Adsorption

    Activated Carbon is another excellent water filtration process. Activated Carbon absorbs many toxins, odors, or taste from the water. Often, household carbon filters use silver nanoparticles to prevent bacterial growth in the filter.

    Ultraviolet (UV) disinfection

    UV Lamp

    UV filters are also famous in India. The advantage of a UV filter is that it does not leave any residual disinfectant in the water. Ultraviolet light passes through the water killing bacteria and viruses. In India, several water purifiers use a combination of both RO and UV for effective water filtration.

    The advantage of a UV filter is no water wastage. Since UV rays disinfect the water, there is no wastage. However, UV filters do not remove any dissolved toxins or chemicals. Hence most water purifiers in India use a combination of RO, UV, and UF for effective filtration.

    Ultrafiltration (UF)

    Ultrafiltration is a type of membrane filtration that uses pressure to push water through a membrane. This process results in particles getting trapped in the layer leaving the water pure and safe to drink.

    UF filters do not remove dissolved solids (TDS) from water. If your well or bore water has high TDS, UF filters will not reduce the TDS concentrations.

    Water purifier buyers guide

    Water purifer buyers guide

    In this section, we present the basics of water purifiers in India along with a simple and easy to follow guide. Water purifiers use a wide array of filters to purify water. Also, one must understand some basic concepts behind water purity. This understanding will help you in choosing the right water filter for your home.

    Things you must know about water in India

    Water purifiers use several acronyms and terminologies. For an average buyer, these acronyms can be confusing. Use the section below to understand what these terms mean.

    Water sources

    Well water

    In India, there are three primary sources of water that people use.

    • Groundwater – Most households rely on groundwater. Borewells and open wells are a common sight in India and are the most common source of water.
    • Municipal water – Municipal government supplies water from lakes, rivers, and other natural reservoirs to our homes through a network of pipes.
    • Other sources – Several households in India also use other sources of water, such as rainwater harvesting, water tankers, borewell water, etc.

    Water Quality

    The quality of water from your water source is the primary factor that will determine the type of purifier that you need. When it comes to water quality, you need to take into account the following.

    • Hard water – The amount of minerals dissolved in water determines its hardness. If you notice a white layer on your taps and shower, then your water is hard. Your soap will not lather properly in hard water. Hard water is not bad for human health. Studies by the United States National Research Council found that hard water serves as a dietary supplement for calcium and magnesium.
    • Soft waterSoft water has a lesser amount of minerals dissolved. We need minerals such as calcium and magnesium in our water.
    • TDS Total dissolved solids (TDS) is another frequently used term in India. As the name implies, TDS is a measure of both organic (bacteria, algae) and inorganic (minerals, dirt) in your water source.

    TDS varies by region and water source. The table below is a general guide for TDS based on water sources. Use a TDS meter to test your water to determine the accurate TDS value.

    Water sourceTDS
    Ground water200 ppm to 2000 ppm
    Municipal water1 ppm to 200 ppm

    Storage capacity

    All water purifiers in India come with a storage tank. RO and UV based purifiers use electricity to filter water. These purifiers also take time to filter water. A storage tank helps store clean water in the event of power failure.

    If you live in a large joint family like most of us do, consider a water filter with a large storage tank. The following are the most common storage tank capacities in India.

    • Up to 7 liters – These purifiers are suitable for apartments and small families.
    • 7 to 14 liters – These purifiers are ideal for large families.

    Greater than 14 liters – These purifiers are useful for commercial establishments or common areas in an apartment complex.

    What are the different types of water purifiers available in India?

    Traditional water purifier

    Water purifiers in India fall under any one or a combination of the below list. The most efficient water purifiers are the ones that use a combination of different purification technologies.

    Gravity based purifiers

    • Filters: Larger impurities such as dirty, algae, and other particles.
    • Does not filter: Does not remove microorganisms, such as Protozoan cyst, bacteria, viruses.

    UV based purifiers

    • Filters: Kills microorganisms, such as Protozoan cyst, bacteria, viruses.
    • Does not filter: Does not remove larger impurities such as dirty, algae, and other particles.

    RO/UF based purifiers

    • Filters: Removes microorganisms, removes particles, and removes harmful chemicals, such as Arsenic.
    • Con: Water wastage is high.

    Combination (RO+UV/ UF+UF) purifiers

    • Filters: Removes microorganisms, removes particles, and removes harmful chemicals, such as Arsenic.
    • Con: Expensive and water wastage is also high.

    Conclusion: Best water purifiers in India 2021

    Save water

    Water is one of the fast depleting resources in the globe today. Our waterways are polluted, groundwater is contaminated, with droughts and lack of rainfall, conserving water is an absolute necessity.

    The Government of India has several projects to conserve and preserve water for our children. Projects such as rainwater harvesting are proving to be invaluable in replenishing groundwater.

    We urge our readers to conserve this most precious resource so that our children and their children can continue to enjoy clean water. Let us do our part in conserving water.
