How a Non Electric (Gravity Based) Water Purifier Works?

Like the name, these water purifiers work on the principle of gravity rather than using electricity. It comes with a transparent tank made up of food-grade plastic that again includes two compartments. When you pour the tap water to the top compartment, the gravity works as the downward force to capture the dirt into the filter. Then the purified water passes to the bottom compartment that is pure and safe for consumption.

Different Filtration Technologies Used in Gravity Based Water Purifier

Pre-filter or Microfiber mesh

This filter comes in the first section of the topmost compartment. When water is passed through it, it filters out the large particles from the water like dust and sand, etc.

Activated Carbon Filter

It is the most important filter in the non electric water purifier that performs the actual purification of water. This filter is made up of carbon granules that catches out the minute and even invisible particles or impurities, salts, micro-organisms, and other chemical contaminants. It softens the water and also reduces bad odor from it.

Post Carbon Filter

Finally, this filter refilters out the purified water making it completely clean and safe for drinking purposes.

Some Important Tips
  • After the installation of a new gravity based water purifier, make sure to drain out the first batch of water as it comes with a distinctive taste of carbon granules.
  • Every non electric water purifier comes with the notification alert for cartridge refilling. When it stops working, the water starts to leakage from the purifier. You must change it for proper purification.
  • When changing the filter, look out for the leakage too. If it happens, replace it with another one.
  • Do clean the storage tank twice a week to get absolutely clean water.
  • If in case, the purified water in the storage tank has not been consumed within two days, discard that water. Fill it again with fresh water.
  • Do not use hot water; only use cold water for purification.
  • Keep away the water purifier from direct sunlight as it may damage the plastic of the purifier or promote algae growth.
  • Don’t scrub the tank with a fiber scrubber or metal mesh.

Features to Look For Before Buying a Non Electric Water Purifier

Capacity

Choosing the right capacity of a gravity based water purifier depends upon the size of your family as well as the water usage. The non-electric water purifier includes two compartments. The top compartment is for holding the raw water, that after purification, goes to the lower compartment as a storage for further consumption.

So, you must consider the storage capacity depending on your family size. For a small family, the one with 10 l capacity is good enough. And for the large family, you may go for the one with 20-25 l of storage capacity.

Material

Gravity based water purifier generally comes made up of food-grade plastic or ABS material. But now, stainless steel water purifiers are also available. Both of these materials of construction are safe to use and ensures the durability of the water purifier.

Type of storage tank

The storage tank in a gravity based water purifier is also made up of non-toxic food grade plastic as well as stainless steel material. It is best to go for the one with a transparent tank. So, you can easily check the status when it needs to be refilled. Stainless steel storage tanks are also good, but here you need to check the level of water by opening its cap or cover.

Purification Rate

The purification rate of a water purifier determines how much water it purifies in an hour. An average family requires at least 5-10 liters of purified water for consumption. So, you must choose the one that can purify at least this much of water per hour. You can consider the purification rate depending upon the size of your family.

Space of installation and purifier dimension

First, consider the space in your kitchen or dining area where you want to install the water purifier. Then, check for the appropriate dimension of the water purifier that ideally fits to the installation area.

Water quality

Checking out the water quality or level of TDS (using TDS meter) in your area is the most important consideration. As gravity based water purifiers are not capable enough to purify the water over the TDS level of 300 ppm, in this case, you may go for RO water purifiers or the purifiers with high filtration technologies.

Filter

Non electric water purifiers include the activated carbon filter as their main part that is responsible to purify the water. It can remove harmful chemicals, bacteria, viruses, and cysts from the water and make it safe for drinking. So, you must choose a filter that can filter around 1500-4000 liters of water and does not require the replacement every fifteen days or monthly.

Maintenance of filter

The lifespan of the filters ranges from 6 months to 2 years, depending upon its filtration capacity. It is recommended to change the filter before the completion of its lifespan. One of the best ways to increase the lifespan of the filter is to clean the water purifier twice a week.

Auto Shut Off

It is one of the most beneficial features of the gravity based water purifiers. It notifies you when the cartridge or filter stops working, and thus leakage of water starts from the purifier. So, it alerts you that the filter needs replacement, and therefore you can get pure and safe drinking water.

Ease of Cleaning

Gravity based water purifier requires cleaning on a frequent basis. Proper cleaning of it ensures you will get safe and purified drinking water always. Choose the one that can easily be cleaned using liquid soap and water. Most of the models come with easy to detach parts for their proper cleaning.

Budget

Assessing your budget before buying any product is the foremost step. Luckily, gravity based water purifiers come with only the pocket-friendly price tag. The good quality non electric water purifier price ranges from Rs 1000 to Rs 4000. So, you can choose the appropriate one suiting your budget requirements.

Warranty and After Sales Service

Always go with the branded gravity based water purifier. The branded model offers at least six months to two years warranty and after-sales service on their product. Some of the best gravity based water purifier brands include HUL Pureit, Kent, Tata, And Eureka Forbes, etc. These all offer the best warranty and after-sales service.
