Everything You Need to Know About Water Filters

Everything you need to know before buying a water filter

Water is a necessary component of life. Water makes up around 60% of the adult human body. Water makes about 73 per cent of the brain and heart. Only 1% of the water on the planet is suitable for human consumption. However, owing to pollution from industrial and factory chemical solvents, as well as filth and germs in the air, even that 1% is becoming unsuitable for human consumption. Water-borne illnesses are also growing at an alarming rate, and people are becoming more aware of the need to drink safe water. As a result, the demand for water purifiers has increased dramatically, and the market is now inundated with various water purifier brands.


Currently, there are a variety of water purifiers on the market. Every water purifier has its selling point, and they all promise to provide the greatest water quality. Keep in mind, however, that all water purifiers have distinct technical characteristics and must meet some fundamental standards.


Knowing which one will work best for you is dependent on aspects such as water pressure, water quality, and available space. If you're not sure which one to choose, check out our article on how to choose a water purifier for home usage.


Now, before we get into which is the finest water purifier for home usage, let's go over some of the most prevalent water purifying methods.


  • Protection against life-threatening waterborne illnesses induced by polluted water
  • Calcium carbonate is removed from tap water to eliminate the strange taste of chlorine (which means it won't ruin your coffee!)
  • Scratches, spots, and scaling on the surface of your cooking utensils are minimal to non-existent.


Here are the top ten factors to consider before purchasing a water filter for your house.


Various Impurities Frequently Found in Drinking Water


The kind of contaminants present in your drinking water is mostly determined by the water's source and transport medium. Lakes, rivers, bore wells, collected rainfall, piped municipal corporation supplies, water tankers, and other sources of drinking water are the most prevalent.


The hardness of water, as well as the number of impurities such as hazardous pollutants, chemicals, and biological impurities such as bacteria and viruses, are all determined by the source of water.

The following are the most frequent forms of pollutants found in water:





Solids that have not been dissolved, such as sand and muck

Where pipes have been broken in a river, borewell, or piped water

The look is muddy or turbid.

Sodium and potassium are dissolved inorganic salts.

Seawater and borewells

Tastes salty or brackish

Calcium and Magnesium are dissolved inorganic substances.

Borewells and river water are both sources of drinking water.

Scale formation and hardness

Compounds of organic origin

Ponds and lakes

Bad odour or foul odour

Chlorine and other decontaminants

Water that is piped in from the city

Astringent flavour

Bacteria and viruses are biological contaminants.

Where pipes have been broken, piped water is used, and water tankers are used.

Waterborne illnesses, biological contamination


When compared to water from bore wells, water from lakes, rivers, and collected rainfall usually has a lower TDS (Total Dissolved Solids). TDS levels in borewell or groundwater are often high, and hazardous chemical impurities such as lead, arsenic, and other contaminants may be present. Biological contamination is more likely in a piped water supply or water kept in tanks (if the pipes are damaged or the storage tanks are not cleaned frequently).


Determine whether the water is soft or hard.


The amount of dissolved solids in water determines whether it is soft or hard. TDS (Total Dissolved Solids) is a measure of hardness that is expressed in parts per million (PPM) or milligrammes per litre (mg/L).


1 ppm = 1 mg/L


Water with a TDS value between 150 and 300 ppm is considered soft, whereas water with a TDS value greater than 500 ppm is considered hard or polluted.


What is the source of the water that your residence receives? It's most likely hard water if it originates from subterranean sources, is delivered by water tankers, or is extracted from deep drilled bore wells. Hard water now has significant levels of dissolved solids such as calcium, magnesium, heavy metals, fluorides, and arsenic. Hard water is unsuitable for human consumption because of all of these dissolved contaminants. Soft water, on the other hand, is water that comes from rivers, rainwater collecting systems, lakes, and municipally controlled storage and distribution systems. Soft water, while not as hazardous, requires treatment before it can be considered safe for long-term human consumption.


Water Purifier Types and How to Match Them to Your Water


  • Purifiers with Reverse Osmosis (RO)


To comprehend how RO works, we must first comprehend what Osmosis is.


Water flows naturally across a membrane from a low solute concentration (low TDS level) to a high solute concentration (high TDS level) in the typical osmosis process (high TDS level). Water molecules are permitted to flow through the membrane's holes, which are incredibly tiny (approximately 0.0001 microns), while the tiniest dissolved contaminants and microorganisms are retained.


Reverse Osmosis (RO) accomplishes exactly what its name implies: it pushes water molecules from a location with higher TDS levels to a region with lower TDS levels. This is accomplished by using a water pump to provide external pressure to reverse the natural flow of water. Water containing contaminants or high TDS is pushed into the RO chamber at high pressure, pushing the water molecules through the semi-permeable membrane and leaving the dissolved particles and other impurities behind. All dissolved particles and contaminants, as well as some input water, are released through a separate outlet, commonly known as RO wastewater.


When purifying water with a high TDS level, RO purifiers are usually suggested. When compared to the input water, the TDS level of the RO purifier's output drinking water is extremely low.


The following are some of the disadvantages of RO technology:

  • Electricity is required: RO purifiers cannot function without power because they utilise a high-pressure electrical water pump to apply external pressure to the input water.
  • Water is wasted because a large portion of the input water is released together with dissolved contaminants, resulting in needless water waste. For every 1 litre of cleaned water, RO purifiers create 3 litres of wastewater.


  • Ultrafiltration (UF)


Ultrafiltration, like RO, purifies water using a semi-permeable membrane. After reading the first statement, you're probably wondering what the difference between RO and UF is since they both filter water using the same way. In comparison to RO, which utilises a membrane with very small holes (about 0.01 microns), ultrafiltration (UF) employs a membrane with considerably bigger pores (around 0.01 microns) (appx. 0.0001 microns).


Ultrafiltration has the benefit of being able to function without power since the membrane has significantly bigger pores and water may move through it naturally utilising gravity. This eliminates the need for external pressure or a water pump. There is also no water wasted because UF purifiers do not hold back any water.


However, UF purifiers have certain limits; because to the greater pore size, UF can only remove undissolved particles and bigger pollutants. It is unable to remove dissolved materials or lower TDS levels. As a result, UF purifiers are ineffective at purifying high TDS or hard water.


  • Purification using Ultraviolet (UV) Light


Ultraviolet purification, often known as UV purification, employs ultraviolet radiation to purify water. A UV purifier destroys or inactivates disease-causing bacteria and viruses by exposing the water to high-intensity UV radiation.


UV purifiers, on the other hand, are unable to remove any dissolved or non-dissolved pollutants or compounds from water. As a result, most UV purifiers on the market utilise external sediment pre-filters to remove undissolved pollutants, as well as an activated carbon filter to remove chlorine and other dissolved impurities.


You can use a UF+UV water purifier if the water has a low TDS level but is polluted with bacteria and viruses and seems muddy.


  • Filters that attach to the tap or faucet, or purifiers that work by gravity

These filters or purifiers are the easiest to use and give the most basic level of water purification. These filters are usually sediment or sediment + activated carbon filters that can remove big and undissolved pollutants such as mud and sand, as well as certain chemicals and microorganisms. Tap/Faucet Filters are extremely tiny and may be installed directly on taps.


Tap/faucet filters have evolved into gravity-based storage purifiers. These purifiers include a storage tank built in to hold input/impure water and enable significantly more sophisticated filtration. The majority of gravity-based water purifiers on the Indian market today include two separate storage tanks for raw and filtered water.


Only utilise tap/faucet-mounted filters and gravity-based purifiers in locations where the TDS level is low and the water is not heavily polluted with biological pollutants such as bacteria, viruses, and other disease-causing organisms.


  • The Most Frequently Used Water Purification Methods


There are a variety of water purification procedures available; however, the following are some of the most widely used water purification methods that have been proved to be suitable for household usage.


Purifier using Ultraviolet Light


UV purification is the most effective way to remove germs and viruses from your drinking water without losing important minerals. UV purification is the most environmentally friendly method of water purification since it does not add any chemicals to the water and does not waste it. UV technology is also a common option for industrial water purification.


Reverse Osmosis Purifier:


Reverse Osmosis (RO) technology is often utilised in both residential and commercial water purifiers. RO purifiers use a semipermeable membrane to filter out hazardous pollutants. Because reverse osmosis eliminates certain vital minerals from your water, RO filtered water may taste flat. It's required if the TDS level in your water exceeds 500 ppm.


Water Filtration using Carbon

How Does Carbon Water Filtration Work? carbon

 Water filtration may be done in a variety of ways currently. Carbon filtration is one of the most frequent techniques used in point-of-use water filters.

Carbon as a filter is considered to be one of the earliest ways for cleaning water, with evidence dating back to Egyptian times. Carbon filters are now employed in residential point-of-use water filters and occasionally in municipal water treatment facilities; they are also used in reverse osmosis systems for the pre-treatment phase.


What is Carbon Filtering and How Does It Work?


Carbon is one of the most effective absorbents known to man, capable of absorbing a wide range of substances. Carbon filtration works by removing pollutants and toxins from water via a chemical process called adsorption.


What is Activated Carbon, and how does it work?


Carbon that has had a tiny electro-positive charge put to it is known as activated carbon. This enables it to draw in and trap even more chemicals and contaminants from the water. When water flows over the ‘activated carbon' filter's surface, the pollutants' negative ions are drawn to the positively charged carbon.


Is there a difference between carbon filters for water and carbon filters for air?


 Most home point-of-use water filters employ   Granular Activated Carbon (GAC) or Powdered   Block Carbon as an alternative. Because of their   greater surface area, carbon block filters are   superior at removing huge amounts of pollutants.   The amount of carbon in the filter and the speed   with which the water flows influence the filter's   effectiveness. Because impurities and pollutants   spend more time in contact with the surface of the   carbon filter, a filter with more carbon and a   sluggish water flow is optimal. The amount of activated carbon in a typical point-of-use filter ranges from 12 to 24 ounces.


Which carbon filter is the most effective?


Filters that employ activated carbon are usually given a grade based on the particle size that they remove. The average range is 50 microns (the least effective) to 0.5 microns (the most effective) (the most effective).


Carbon filters are effective in removing chlorine, silt, volatile organic compounds (VOCs), pesticides and herbicides, as well as a variety of other man-made pollutants from water. Some activated carbon filters are somewhat successful at removing some residues of heavy metals from water. Carbon block filters with a densely packed structure may remove particles as small as 0.5 microns. Salts/minerals (contaminants that create scale on kettles or coffee makers) and dissolved inorganic compounds are not removed. A reverse osmosis water filtration system or a distiller are required to remove these pollutants.


GAC is ineffective in removing silt and particle matter. GAC filters are frequently used with a sediment filter that comes before it, making it more effective and extending the life of the carbon cartridge by removing impurities that might clog it. Secondary materials are utilised in many carbon filters used in water filtering to prevent bacteria from growing inside the filter.


What exactly is TDS?


Total Dissolved Solids (TDS) refers to the number of dissolved solids in your water. TDS is made up of inorganic salts and trace quantities of organic compounds dissolved in water. TDS levels in the human body should not exceed 500 ppm. Unlike surface waters, groundwater (water for bore wells and tube wells) has a high TDS (water from rivers, lakes, reservoirs, ponds).


How Can I Choose the Best Water Purifier for My Home?

How Can I Choose the Best Water Purifier for My Home

While there are numerous water purifiers available online, the factors listed below will assist you in determining which is the finest water purifier for home-usage.


Which of the several types of water purifiers is best for your water?

Is your water surface water (from rivers and lakes) supplied by the municipality, groundwater (from borewells, delivered by tankers), or a combination of the two?


If it's municipally provided surface water, the TDS (dissolved impurities) are likely to be minimal, and you just need to worry about microbiological contaminants like bacteria and viruses. If your water is tanker-supplied groundwater, however, there may be a higher amount of dissolved pollutants, changing the flavour of the water and, at higher levels, perhaps affecting your long-term health.


If you obtain groundwater, check the TDS using a basic TDS metre as a rule of thumb. If your TDS level is more than 500 ppm, a RO water filter may be useful. A well-designed UV purifier will be efficient in purifying the water if the TDS is less than 500 ppm. If both ground and surface water are present, an "intelligent" purifier with sensing purification technology will be efficient.


This basic TDS test is performed by the majority of water filter firms. It's worth noting that utilising a RO water purifier where TDS levels are low, say under 200 ppm, might be harmful to your health over time since the water is stripped of vital minerals and salts.


A RO water purifier wastes a significant amount of water (up to 80%), thus excessive use is a waste of a precious resource.


Take a peek at Alfaa's Presence - a universal water purifier that purifies any variable water source, such as bore well, municipal, or tanker water, by automatically picking the appropriate technology: UF, UV, or RO, based on the customer's TDS setting (Total Dissolved Solids).


What is the minimum water pressure necessary for a water purifier?


Before you buy a water filter online, make sure you check the water pressure. Water purifiers typically require a pressure of 5-40 PSI (pounds per square inch) to function properly.


Calculating the pressure in your tap is as simple as counting how many levels you are away from the terrace where water is delivered by gravity.


If you reside on the eighth level of a ten-story structure, your water pressure is likely to be 10 PSI, because every 10 feet from the top is comparable to 5 PSI. The pressure in your tap will be about 45 PSI if you reside on the first floor. If this is the case, a pressure-lowering valve, as well as the water filter, will be necessary.


A booster pump or a UV purifier that runs on a loft tank will aid houses with very low pressure.


Quality of Water

Quality of Water

Consider the quality of the water you have at home before deciding on a water filter that meets your needs. Water quality varies from one location to the next. Some water contains sediments, while others contain unseen bacteria and viruses that might harm your health. If there are any sediments in the water, the physical look of the water will usually reflect this. Water's odour and flavour can also indicate the presence of dissolved contaminants. When water is stored in a steel utensil, white spots appear, indicating that the water contains hardness (calcium and magnesium).


In these situations, RO is the best option. The membrane of the RO is semi-permeable, with a pore size of 0.0005 microns. The smallest dissolved salts, metals, and contaminants are removed via these pores. You may also have your water tested to check if there are any contaminants in it. Heavy metals in the water, such as lead, mercury, and arsenic, can cause health problems. Once you've learned about the water quality in your area, you'll be able to make informed decisions. It will be simple to select a water purifier.


The acceptable maximum of TDS in drinkable water, according to the World Health Organization, should be between 50 and 120 PPM, and the pH should be above 7.4. If you obtain your water from the municipality, it should have less than 120 TDS, and you may use a purifier system instead of a RO system, such as Aquaguard, Kent Maxx, Vivid Star Neptune, and other UV/UV+UF purifiers. If you obtain your water from a bore system, you should always utilise a RO system since bore water has a high TDS because it travels from under the earth's surface, where heavy metals dissolve.


  • Smell the Water:Use your sense of smell to assess the water's purity. If your water smells like bleach, it's because the local treatment facility adds chlorine to it. If you detect a rotten-egg odour, it means there is bacterial growth in the water. The presence of a musty or earthy odour in the water suggests the decomposition of organic materials.
  • Check the Taste:Use your taste sensibilities to assess the water's purity. If the water has a nasty or metallic taste, it has a low Ph level or contains too many minerals. When there is too much chlorine in the water, it tastes like bleach.
  • Particles:Check to see if there are any visible minute particles in the water. Tiny rust particles can be seen in water as a result of rust in pipes and faucets. Aside from that, if the water seems murky, it suggests that the water contains a lot of calcium and magnesium.
  • Examine the Color:If the water is brown or pale yellow in hue, you'll need to get a water purifier right away. Rusty pipes and faucets may be to blame for the darker, murkier discoloured water.
  • Corrosion build-up:Examine your pipes and faucets for corrosion. The presence of foreign particles in the water is indicated by the appearance of blue, white, or rust-coloured buildup in pipes.


Specific contaminants are removed by water purifiers.


Water purifiers remove pollutants from water using a variety of methods. However, this does not imply that all water purifiers are capable of removing all types of pollutants. Test the water quality in your region before purchasing a water filter to determine which one is best for you. You may choose between RO and UV water purifiers depending on the water quality in your region. You should also verify whether the water purifier has received NSF certification.


The following are the several types of water contamination:

  • Biologicalpollution is caused by the presence of microorganisms. Bacteria, viruses, protozoans, and parasites, for example.
  • Chemicalpollution is almost often caused by humans. Bleach, salts, pesticides, and other contaminants, for example.
  • Physicalcontaminants consist mostly of silt or organic particles suspended in the water. The physical appearance of the water is affected by these pollutants


Technology & Purification Process


Comparing the filtration technique of different water purifier brands is the best method to choose between them. Water filtration technology has an impact on water quality. The polluted water is filtered by some process in every water purifier. These requirements have their labels, like RO, which stands for reverse osmosis treatment. Hardness, metals, ions, polymers, and bigger particles are removed from drinking water using a semi-permeable membrane. Then there's UV, which stands for Ultraviolet water purifier, which utilises UV rays to destroy bacteria in the water. Then there's Ultrafiltration, abbreviated as UF. To filter germs and viruses from water, UF employs hydrostatic pressure against a semipermeable membrane. TDS control refers to a purification process that regulates the final TDS and, as a result, the flavour of the water. pH Balance Technology is a new water purifier technology that balances the pH levels in the water. You must examine several purification processes included in the water purification process. This product can be chosen based on the purifying technology that best meets your needs.


Consider how much water your household consumes.


When shopping for a water purifier, keep the size of your household in mind. The reason for this is because water purifiers include a storage capacity so that you can obtain filtered water even if you don't have access to energy. So, before making a final decision, think about how much water your household uses and how much water is needed for cooking. If you have a large household, a countertop or under-the-counter water filter is recommended.


Should I Get a Water Purifier or a Filter?


RO technology has become synonymous with water purifiers, and you've probably heard water purifiers referred to as RO (like the brand Xerox has become synonymous with photocopying).


As a result, most people believe that when it comes to purchasing a water purifier, RO water purifiers should be purchased by default, without taking into account the most essential factors such as the source of water and the TDS level of the input water.


If you've read through the entire explanation, you're aware that RO filtration is only necessary when the water entering your house or business has a high TDS level (generally higher than 500 ppm).


There are several types of water purifiers on the market nowadays, ranging from basic tap/faucet filters and gravity-based purifiers to UF, UV, RO, and their combinations. The complexity of choosing the correct water purifier for your home or business has risen due to the huge array of various technologies and thousands of different water purifier models from tens of hundreds of different manufacturers.


As previously stated, a RO purifier should only be purchased if the water to be filtered has a high TDS level. The maximum TDS level for safe drinking water has been set at 500 ppm by the Bureau of Indian Standards (BIS).


If the TDS level is less than 500 ppm, there is no need to use a RO purifier. Because if your water supply has a low TDS level, the RO purifier will lower it even more to a very low TDS level. As a result, the filtered water will be lacking important minerals such as calcium and magnesium, which are necessary for human health.


If the incoming water's TDS level is less than 500 ppm, you should inspect it for turbidity (clarity), muddy appearance, or the presence of biological contaminants such as bacteria and viruses.


Though water purifier manufacturers strive to set themselves apart from the competition by touting sophisticated water purification technology, the majority of them employ a combination of three primary purification methods: reverse osmosis (RO), ultraviolet (UV), and ultrafiltration (UF) (ultrafiltration).


If you don't want to get into the technical details of the various purification methods, use the checklist below to help you find the perfect purifier for your home or business. Here we'll go over all of the criteria you'll need to assess and select the best water filter for your requirements.

  • TDS levels in soft water are low, and UF water purifiers function effectively with it.
  • A UV or UF+UV water purifier is recommended for a soft water with a high degree of biological contaminants.
  • Apart from particular pollutants, hard water has a greater amount of TDS, therefore RO-based purifiers are ideally suited for filtering it.
  • A RO+UV or RO+UV+UF water purifier is recommended for hard water with a high degree of biological contaminants.
  • Because UF filters do not destroy microorganisms in polluted water, they are best utilised in conjunction with another water purification device. Only suspended particles are removed from water using UF filters.
  • Water purifiers with activated carbon are great for removing excess chlorine from water.


Refrigerator Water Filters: How Effective Are They?

Refrigerator Water Filters

Refrigerators with built-in water filters seem like a great deal—you need a refrigerator anyway, so why not purchase one that filters your water? While certainly better than nothing, refrigerator filters have significant limitations when compared to dedicated whole house or countertop filtration systems.


What is filtered in this case? What are the benefits of using refrigerator water filters?


Chlorine, volatile organic compounds, radon, benzene, and a variety of other man-made pollutants, as well as unpleasant tastes and smells, are all removed by activated charcoal. Built-in refrigerator filters perform a good job of eliminating these dangers within the confines of their tiny size, but less efficiently than bigger systems. However, activated charcoal alone is insufficient to eliminate all waterborne pollutants.


Carbon filters provide little to no protection against a variety of inorganic pollutants and heavy metals, including:


  • Arsenic \sBarium
  • Beryllium
  • Cadmium
  • Chromium
  • Copper \sFluoride
  • Mercury \sNickel \sSelenium \sSulfates
  • Thallium


Lead may be removed using highly specialised activated charcoal filters, however these filters are rarely seen in refrigerators. Reverse osmosis filters may remove minerals, lead, and other heavy metals.


Issues of Convenience


A built-in refrigerator system may appear useful at first look, but keep in mind that it only delivers filtered water in one location: your kitchen. Whether you're cooking, cleaning dishes, bathing, or washing clothes, a whole house filter provides cleaner, safer water from every tap in the house.


Filter Lifespans Are Limited, Which Means More Money


One last point to consider with built-in refrigerator filter systems is the expense of filter replacement. Because activated charcoal filters absorb pollutants, they ultimately clog up and need to be replaced. This is true for both a whole home and a small fridge filter, with one notable exception. Because a whole house filter is larger, you may replace it less frequently, resulting in less bother, more convenience, and less financial strain on your wallet, as well as a more efficient water filtration solution.


In 2021, these are the top seven water filters.


  • APEC ROES-50 Reverse Osmosis System.

"Be sure to do your due diligence as a consumer and compare filters and replacement cartridges. If something seems too good to be true, then there is a good chance it may be a counterfeit. Counterfeits are a problem for a number of reasons. First and foremost, they likely won’t remove the contaminants you expect them to and could therefore pose a health risk. Also, if they are made with substandard materials that leach they could actually make your water worse. The number one indicator of a counterfeit is price. Counterfeit filters and replacement cartridges usually cost significantly less than authentic certified products."- NSF International's Global Business Development Director, Rick Andrew

       Reverse Osmosis System      

  • Water Filtration System for Faucets by PUR


  • It also eliminates a variety of pollutants such as lead and other heavy metals, chlorine, pesticides, and other toxins.

A decent water filtration system can safeguard your family's health and keep them safe from pathogens. Water that has been contaminated will do more damage than good. Rather than being swayed by marketing, choose a water filter after obtaining and analysing facts. This is critical for making health and family-related decisions. Always examine all of a water purifier's functions before deciding which one is ideal for you.


The source of water and the sort of pollutants present in the water delivered to your house or business are the single and most important factors in determining the type of water purifier you should choose.
