Why RO Purifiers?

RO water filters are an excellent option for most Indian houses. RO (Reverse Osmosis) purifiers are top-rated in India, and the word “RO” has come to be associated with “water purifiers.” RO water purifiers remove all of the most prevalent contaminants, including UV, UF, and MF. That is why they are also known as “Universal Water Purifiers.” The most dependable water purification process is Reverse Osmosis (RO) purification.

Multi-staged RO purifiers can rapidly remove dirt, sand, germs, viruses, excessive dissolved solids like calcium and magnesium, and other contaminants. Other water purification devices (used in homes) cannot reduce the TDS level of water or eliminate hazardous heavy metals such as lead and arsenic.

Buying Guide- How to Choose the Best Water Purifier?

There are several things to consider while selecting the best water purifier for you. We’ve compiled a list of the most important factors below:

1. Water Type

The type of water source at your home is one of the first concerns you’ll want to address. This will be the starting point for purchasing a suitable water purifier for you.

As we already know, the concentration of pollutants and chemicals can vary from location to location. Now, for example, if you want to see whether you’re getting hard water, boil it and check. Hard water usually causes a furring of your vessel when it is boiled due to its ions.

There are a few more issues to worry about, such as difficulty cleaning clothes because of lather formation or problems with hard water. This can be due to soft water, and soft water is generally found in lakes and rivers and has fewer problems with it.

Select a water purifier dependent on the water supply at your home. Reverse Osmosis or RO is usually one of the finest choices for hard water because it has been proven to address this problem successfully.

2. Contaminants Differ

There are many contaminants you may come into contact with. Your water source and its unique impurities aren’t all going to be able to be dealt with by every water purification system. Water purifiers differ in their ability to treat water. Some microorganisms can still get through some types of filtration systems and potentially harm your family and yourself, even if the system is installed correctly.

Before making your final purchase, you must thoroughly understand all the different filters on the market and how they work. Consider your home’s water situation and make an informed selection.

3. Filter and Cartridge

Ensure that the water purification system you choose includes an activated carbon or sediment filter. Sediment filters are required to eliminate large physical particles like dust and dirt from the water, including those found in tap water. While the activated carbon filter can be beneficial in eliminating any noxious odours or volatile chemicals that you may be dealing with.

If you obtain a Biotron cartridge, it will assist since it can break down the molecules in the water. You may quickly enjoy the benefits of nutrients within the water after this.

A mineral cartridge will be required to guarantee essential minerals are retained in your water, as well as the taste and pH balance.

4. Availability of Water

The amount of water available in your home is the critical factor. Many people in India do not have access to a continuous water supply. Some types of water purifiers, for example, may need a significant quantity of water to operate effectively.

If you’re considering an RO type of water purifier, keep in mind that it will typically discard around 50% of the water. As a result, if you have a local water shortage, it won’t be one of the most excellent alternatives.

5. Maintenance of Water Purifiers

It’s critical to keep your water purifier in good working order. However, it doesn’t have to take up the whole day. Nobody likes adding another chore to their daily cleaning.

Some water purifiers will need to be cleaned regularly, whether you like it or not. Otherwise, they will become useless, and their life span will shorten. One of the water purifiers that requires special care is the Ultra-filtration or UF water purifier. If you want it to function adequately, you should clean its membrane once a week after each week.

If you can’t find the time to do this, you may want to contact RO or gravity-based water purifiers for assistance.

6. Type of Installation

Water purifiers can be installed in various ways, and they may be mounted on the wall or placed on a kitchen counter. For a sleek appearance, you may select from some of the most stunning designs that suit your kitchen’s décor.

However, if you have a restricted amount of space, an under-the-sink installation will keep it out of sight.


Which is the Best Water Purifiers Brand in India?

Here are some of the best water purifiers available in India, along with a few comments about each. These companies are well-known for providing high-quality goods and excellent after-sale support.

  • Kent

The Kent Purifiers are ideal for households and are long-lasting. This efficient purifier will benefit you if your water supply is not clean.

  • Eureka Forbes (Aquasure & Aquaguard)

They offer two different brand names for their water purifiers: Aquasure and Aquaguard. Aquasure water filters are low-cost water purifiers produced by the firm, whereas Aquaguard is intended for high-end consumers who usually pay a higher rate. The Eureka Forbes water purifiers have a lot of history in the business and have earned a bad reputation.

  • Pureit

The Pureit water purifiers are very cost-effective and simple to use. These purifiers may be used in environments where the water supply is contaminated.

  • AO Smith

AO Smith doesn’t just sell water purifier equipment. The American firm provides its worldwide clients, including Indians, with water heaters and boilers. AO Smith’s reputation has been etched in the minds of many Indian citizens because it was the first American business to break into the Indian water purifier market.

Types of Water Purifiers used in Home

We’ve gone through the many types of water purifiers and purification procedures available on the market. This part will help you pick the best option for yourself.

1. Reverse Osmosis Water Purifier | RO Water Filter

Reverse Osmosis, sometimes known as a RO system, is a form of water purification with a semi-permeable membrane to keep drinking water quality high. The water in the RO type water purifier passes through the intake channel, filtered by the semipermeable barrier, which prevents all dirt, chemicals, and heavy metals from entering.

If you get a hard water supply, consider using RO water purifiers. One of the most remarkable features of this system is that it can treat hard water, making it particularly suited for Indian homes. Microorganisms of various types may have a detrimental impact on your and your family’s health. An RO water purification system helps to keep these contaminants at bay while providing you with clean water. It’s also an excellent way to get rid of smelly water.

2. Ultraviolet Water Purifier | UV Water Filter

Over time, newer technologies emerge, and we’ll look at how UV is used in water purifiers. This kind of water purifier helps eliminate germs without using any chemicals. And it’s a fantastic concept!

The goal is for the water to go through a UV tube that creates UV light, which aids in the water purifier’s effectiveness against even the most dangerous and deadly germs. Even if some germs survive the slaughter, their strength is likely reduced.

The equipment is also straightforward to use, and all you have to do is swap the UV tube once a year (if required) or if it breaks.

3. Ultrafiltration (UF) Water Purifier | UF Water Filter

Like the RO water filters, the Ultrafiltration or UF water purifier utilises a membrane to prevent all solid particles from passing through it. This technique helps you catch big things, trash, and even microscopic germs and keep them from flowing with the water.

While RO may be a good choice for most properties, it is not always the best option. The people who can benefit from this water purifier are not dealing with hard water in their region. When it comes to giant germs, the device is fantastic, but it may fall short in terms of tiny organisms. To keep any kind of undesirable build-up at bay, you’ll also have to clean the membrane regularly and daily.

4. Gravity-Based/Non-Electric Water Purifier

Have you ever heard that gravity is used to purify water before? You have now. This water purifier accomplishes this as well, and it’s sometimes accompanied by activated charcoal or even a UF type filtering membrane to eliminate pollutants and contaminants.

The gravity-based water purifier also removes debris with a fibre mesh, in addition to its chemical filtering abilities. This purification technology does not require electricity, one of the most excellent features! You avoid both power and money!

It does have one disadvantage, though, and it cannot eliminate or remove the various germs that might cause illnesses.

Benefits of Using a Water Purifier

India’s waterways have been steadily deteriorating due to various causes, which is hazardous since they are the primary water source for multiple purposes such as drinking. The government is undoubtedly working toward cleaning the water, but it is not a problem that will be resolved quickly. We also require an immediate solution to this problem, as evidence that we are still talking about it now.

One of the more disturbing statistics to emerge over time is that 1,200 people die every day in India due to water-related illnesses. One of them reveals that the cause of death in children under the age of five is Cholera and Diarrhea, linked to drinking unclean water. This reason alone may be enough to begin using home water purifiers.

However, there are many more advantages of using a water purifier in an Indian home, and we’ve compiled a list of them below:

1. Clean & Safe Drinking Water:

One of the most apparent reasons to utilize a water purifier in India is to get clean and safe drinking water for yourself and your entire family. This gadget helps you eliminate almost 99 percent of germs, chemicals, parasites, and pesticides that a quick boil on the stove will not be able to remove.

2. Removes Industrial Chemicals:

You may not be aware that the water you’re drinking might contain some of the most severe industrial chemicals. Autilise new technology developed to work in water purifiers is used in your Brita filter to remove these contaminants and give you clean and pure drinking water.

3. Reduces Water Hardness:

It is best to drink water from a bottle rather than from the tap in India because it is hard, which isn’t good for your health. RO water purifiers can aid you in decreasing the hardness of water and making it safe and pleasant to drink.

4. TDS Controllers:

A TDS controller is a feature that many water purifiers have. These filters allow you to inspect the quality of your drinking water and keep providing you with the highest and most dependable water possible.



  • Which water purifier is best for Borewell water?

The average water used for washing clothes has a high TDS (total dissolved solids), making it unsuitable. The water may contain common minerals such as iron, magnesium, sodium, calcium and heavy metals like arsenic, fluoride, mercury, and lead. For this reason, we advise choosing RO systems. To handle the pollutants in Borewell water, you’ll want to look for a BORING system coupled with UV purification.

  • Which is the best water purifier for home use?

The Kent Grand 8-Litre Mineral RO+UV+UF Water Purifier is the best water purifier for your house.


  • Is the RO water purifier good for your health?

Yes, RO water purifiers are one of the most dependable types on the market. While RO purifiers will remove pollutants, they may also eliminate certain necessary minerals.

Because RO purifiers remove so many minerals, you may not receive enough of them. This might result in an electrolyte imbalance and other problems since demineralised water does not include all the essential minerals in natural spring water. This is dependent on whether you’re paying the same in food. RO purification is the only technique that provides such a trustworthy water quality.

There is no doubt that RO water purifiers have no adverse health effects.

  • How much water is wasted by an RO purifier?

The biggest issue with RO purifiers is the loss of water. For every litre of clean water produced, you can expect roughly twice that amount to go down the drain. The quantity of water lost is also affected by the TDS levels in your water. It’s been noted that RO purifiers waste more water in regions with high TDS.

  • How do you use rejected water?

The rejected water is unsafe to drink because almost all of it is impure or polluted. On the other hand, this water may be utilised in various ways to prevent wasting it. This water may be used for multiple things, including dishwashing, floors, bathrooms, and toilets. If you have plants in your home, you can also water them with this unused water.

  • Is it safe to buy a water purifier online in India?

It ultimately comes down to your attitude toward online purchases. Purchasing water purifiers is usually relatively safe, especially if you’re buying from reputable manufacturers. However, if you prefer to inspect the product physically, that’s entirely up to you.

However, you may discover better bargains online because of the eCommerce war. On Amazon, for example.
