Best Gravity-Based Water Purifier In India

Gravity-based water purifiers do not require electricity for the purification process; instead, they imply UF or activated carbon for making the water pure. Activated carbon is made up of small-sized particles of carbon that remove all the impurities and germs from the water. On the other hand, UF is a hollow fiber membrane that restricts the movement of impurities while water passes through it.

How does Gravity-based Water Purifier Works?

Gravity-based water purifiers work through the normal force of the earth’s gravity and do not need any electricity for their operation. The purifiers filter through the activated carbon, UF, or microfiber mesh from the top compartment to the lower point.

Fiber mesh is nothing but a cloth that removes dirt and other impure particles. Activated charcoal is composed of granules of carbon that terminates the pesticides and parasites from the water. The water then passes through the module of the polisher that gets rid of all the harmful chemicals and undissolved chlorine.

There are some models of gravity-based devices that use UF technology for the purification procedure. The filtration mainly occurs through a UF membrane. The membrane contains 0.1 microns, that are enough to filter out microorganisms and bacteria. We will suggest you go for the UF-based water purifiers if you are thinking about buying gravity-dependent ones.

Moreover, these types of water purifiers are ideal for home and corporation or municipality water. The water filtered by gravity-based purifiers is safer than boiled and chemically treated waters.

5 Different ways to purify river water

What Is Water Intoxication

How to Choose the Best Water Purifier in India:

The Human body is made up of 70% of water and is one of the necessities in our life. Nowadays, buying a good water purifier has become quite a confusing task as there are thousands of models with multiple functions manufactured by several companies assuring purified drinking water. But the correct knowledge will help you to select the perfect one based on the source of your water supply.

We have created a buyer’s guide based on the different technology, types, and water storage capacity of a purifier.

1. Total Dissolved Solids:

Total dissolved solids or TDS are the different types of constituents present in the water. TDS is measured in parts per million (PPM). It decides which type of filter should be chosen for your area. Total Dissolved solids are nothing but a total value of charged mobile ions present in a certain amount of water which includes metals, cations, minerals, and anions.

Some of the regions in India have arsenic-filled water supply, i.e., with high TDS levels. There are four types of water purification systems which are Reverse Osmosis (RO), Ultraviolet (UV), Electro Adsorption (EO), and Ultrafiltration (UF).

1.1. Reverse Osmosis (RO) System

Reverse Osmosis RO System

Reverse Osmosis (RO) purification is the most reliable water purification technique. It has advantages over conventional purification methods. Multi-stage RO – Purifiers are capable of effectively dislodging heavy metals like lead arsenic oxide and ch2e from clean wastewater

Water purifiers with a reverse osmosis mechanism come with a pre-filtration technology that can purify even muddy or dirty water. They can convert the taste of saline water into freshwater (desalination). This type of system is effective in those regions where the TDS level is 200 to 2000. Moreover, it can purify water from harmful chemicals, fluoride, lead, or arsenic.

1.2. Ultraviolet (UV) Technology

UV purifiers cannot perform desalination of the water. They kill the microorganisms like cysts, bacteria, viruses, protozoa, and chlorine. The machines with UV technology cannot remove the terminated organisms from the water. It cannot eliminate the dissolved particles that are present. Moreover, UV technology performs an express disinfection process making it a super-fast model among the purifiers.

1.3. Electro Adsorption (EO) Mode

Water purifiers with Electro Adsorption (EO) Mode perform five levels of purification. It is mainly ideal for areas that have a water supply of less than 500 PPM. The five stages are:

  • First level: Prefilter provided by the machines externally removes dirt, sand, and dust in the water through the water filter.
  • Second Level: Mechanical filter further removes all the dirt and dust by pushing the water through a sediment mesh.
  • Third Level: All the negative charges, bacteria, and viruses are eliminated by an Electro Adhesion Filter.
  • Fourth Level: It filters lead or arsenic-like heavy metals through the special carbon granules and exchange of ions
  • Fifth Level: Electro Adsorption Filter terminates the remaining toxins, pesticides, and chlorine present in the water.

1.4. Ultra Filtration (UF) Method

This method is ideal for regions with low TDS. Mainly nonelectrical, which has a storage capacity of up to 13 liters. Purifiers with UF technology cannot provide proper protection against viruses and impurities. The Ultra Filtration method is the only nonelectrical purifier that can eliminate cysts.

2. Different Varieties of Water Purifiers:

There are different types of water purifiers based on the storage capacity and electric options, which are:

2.1. Non- Electrical excluding storage

These water purifiers can be used by fixing directly to the water tap. The device is made up of a candle-shaped resin filter that needs to be changed every month. Activated carbon filters remove all harmful and toxic waterborne pathogens.

2.2 Non-Electrical, including storage

You can store enough supplies for a day in these water purifiers if you have a family member of 2 to 3 persons. Activated carbon and sediment filters, smooth operation without electricity, and storage facility have made it a favorite among users.

2.3. Electrical including storage

This type of water purifier runs on electricity and should always be connected to the water supply. They efficiently remove all the impurities through UV or RO purification mechanisms by using sediment and activated charcoal filters.

2.4. Electrical Excluding Storage

These water purifiers are ideal for those with a constant electricity supply throughout the year. It also has sediment and an activated charcoal filter to process the water and purify it to drink.

2.5. Electrical with Pumps

This device can draw water stored in a container with the help of a built-in pump. You can choose this type of appliance if your area has no or low water supply.

3. Storage Capacity

Water storage capacity is another major factor in a filter. You can choose an automatic on/off purifier, which will start working instantly once the water level goes down. Storage capacity and proper filtration of water are the two aspects that you should keep in mind while buying this device.

Wrapping it Up for the Best Water Purifier

After comparing all the water purifiers manufactured by different companies, our verdict for the best water purifier in India is KENT Grand 8-Litres Water Purifier. Based on the power of RO, UV, and UF, storage capacity, power consumption, and purification stages, this water purifier has emerged as a clear winner in the field of purification of water.
