10 Best water purifier under 20000

Every human being needs access to pure, clean drinking water. However, it is not available to everyone. Many parts of the world suffer from a water shortage, including India, and people in these regions are forced to rely on tankers or contaminated groundwater for their water needs. These days, more and more people are buying water purifiers to purify their drinking water.

With so many brands and models available on the market, it’s easy to get overwhelmed while buying a water purifier. There are numerous types of water purifiers available on the market, so you should take the time to learn a few things before you shortlist water purifiers.

Before choosing the type of water purifier you need, you need to understand where the water is coming from and the quality of the available water. Today, in this post I will show you some of the Best water purifier under 20000 available online in India.

Can I test TDS at home?

The easiest way to test the TDS in your water is to bring it to a lab or buy a TDS meter online or from a store near you.

TDS is usually considered an excellent indicator of water’s quality; if it is below 200 parts per million (ppm), the weather is good to drink. On the other hand, you may still wish to get it purified to get rid of harmful bacteria and viruses. Generally, the average TDS of the water supplied by most municipalities is less than 200 parts per million. In groundwater, the TDS levels are usually between 200 ppm and 3,000 ppm, and it would be best to purify such water through an RO water purifier.

Things To Consider while Buying a water purifier under 20000 in India

Check out the following list before you buy a water purifier under 20000 in India.

01. Water Purifier’s Storage Tank Capacity

As soon as you decide which type of water purifier is best suited for your needs and the amount of water you need to store, you need to find out how much storage space you need. The drinking water consumed by each person in the household usually ranges from 2 to 4 liters per day. So, if you are planning to use filtered water in one go, you need to calculate how much of this water you will require. 

02. Hot & cold water facility

Depending on which water purifier you choose, you may be provided with both hot and cold water after the purification process. However, water purifiers are usually more expensive and can only be found in high-end stores.

Choosing the right water purifier storage tank:

03. Plastic vs. Stainless Steel

In most cases, food-grade, durable plastic is used in the storage tanks of water purifiers. However, some manufacturers are now offering stainless steel tanks. It has been claimed that water that has been purified and stored in the plastic storage tank of the water purifier for a long time may become contaminated again with bacteria and germs. Storage tanks made out of stainless steel (as opposed to plastic) provide more extended safety periods against bacteria and germs.

Depending on the brand, there are even UV lamps inside the storage tanks for killing bacteria if the water is left unused for a long time. Nonetheless, water purifiers with stainless steel tanks tend to cost a bit more than those with plastic tanks. According to some experts, stainless steel tanks are unnecessary, and the water rarely gets contaminated before it is used.

04. Parts availability:

Another essential point you should investigate while purchasing a purifier. In such situations, you are required to use substandard parts or purchase a new water purifier. So, it would be better for you to buy a newer model from any brand, and if you do buy a newer model from any brand, you should find out how long they will support that model for spare parts.

05. Warranty and annual maintenance cost

However, some brands offer a free AMC (Annual Maintenance Contract) for at least 1-3 years. In AMC, the membrane and filters are changed regularly every six months to a year, and the labor costs are included.

As for the maintenance and repair costs, gravity water purifiers tend to cost the least, while RO and RO+UV water purifiers are the most costly in terms of their maintenance and repair costs. Hence, you might be interested in acquiring models that come with free maintenance contracts. 

You also need to check the following:

  1. Service quality: is one of the most critical aspects of its process. Check with your friends, family, relatives, and acquaintances to find out their experience with the brand of their water purifier.
  2. Service coverage and speed: It is essential to verify the brand’s coverage for your area before you choose. This will help you to select the perfect option for you.
  3. Cost of filters: Filters, such as RO and other filters, are not the same, so you must find out how much you need to spend on replacement parts about once a year on average.

Types of water purifier under 20000 in India?

Following are the types of water purifier under 20000 that are available online in India.

01. RO Water Purifier:

During the process of RO (Reverse Osmosis) water purification, a pump pushes water at high pressure through semipermeable membranes with pores about 0.0001 microns in size through a chamber that has semipermeable membranes. Dissolved solids and impurities are left behind during the transfer of water molecules from one side to the other. During the treatment process, some of the input water and impurities will be discharged through a separate outlet. This is known as the reject line.

This filter is responsible for removing all suspended impurities from the water. Second, the Activated Carbon Block filter removes chlorine and bad odors and adsorbs pigments and toxins from the water. Drinking water tastes and looks better after filtration through an RO membrane.

02. Gravity Water Purifier

A gravity-based water purifier works by forcing the water through a membrane of filtration that is pushed by gravity. Also, all this is accomplished without electricity. You can choose from various gravity filters, including Ultra-Filters (UF), Carbon Blocks, Ceramic Blocks, and Non-Viscous Media. These purifiers can rid water of chlorine, cysts, dust, and large solids. However, this type of water purifier can’t remove dissolved solids and some viruses, so it’s not recommended if the input water has a TDS of over 500 ppm.

03. UV Water Purifier

Uv lamps effectively neutralize bacteria and viruses in water purifiers using ultraviolet light. The filtration process is fast with such water purifiers. Despite this, they cannot remove any dissolved solids and contaminants from the water. 

04. RO+UV Water Purifiers

A few high-end water purifiers use both RO and UV technologies to purify the water. RO membranes are first used to filter the water, and then through a UV chamber to effectively neutralize bacteria and viruses.

Frequently Asked Questions

In what way does reverse osmosis work?

The reverse osmosis water purifier systems use a semipermeable membrane that lets only pure water pass through, allowing the purified water to be consumed. During purifying the water, the harmful particles are removed from the water.

Would it be possible to conserve rejected water?

Yes, the advanced purifiers are very water-efficient, having an advanced Save Water Technology built-in. 

How much does RO purifier maintenance cost?

It is essential to maintain a water purifier to ensure that it works effectively. The RO water purifier won’t need a lot of maintenance in the first year, but after that, it may cost approx. Rs 4500 keep it running. Additionally, a water purifier must be cleaned regularly for hygienic reasons. It is recommended that you replace the filters every six months or after a year, depending on usage and water quality.

Precisely what are Total Dissolved Solids (TDS) in water?

Many natural sources of water can become contaminated before it reaches your taps for various reasons. Minerals dissolved in water, including heavy ions and salts, are called Total Dissolved Solids (TDS). 


Due to the increasing water pollution, water purifiers have become necessary for everyone’s home. Despite this, people have many questions before purchasing a purifier for their homes. Hopefully, the above mentioned buying guide on water purifier under 20000 has clear all doubts and may have assist you in making the right decision regarding a water purifier.
