Working of Gravity Based Water Purifiers

Working of Gravity Based water purifiers

Gravity-Based water purifiers function without electricity. Instead, they use the principle of gravity to purify water. Most, gravity-based water purifiers come with a transparent tank made of ABS food grade plastic or stainless steel, which consists of two compartments. The water is filtered as it flows from the top compartment to the bottom compartment without the help of any external force.

These water purifiers normally use an activated carbon filter along with a microfiber mesh (MF) or Ultra-Filtration membrane. The water flows through the membrane whose minute pore size blocks the coarse particles like dirt and dust, bacteria, viruses, cysts, parasites, etc. It allows only the clear and pure water to pass through it. However, it is suitable only for water with low TDS since it is not able to remove dissolved solids or heavy metals.

The filtered water is collected in the storage tank for the ready availability of purified water at all times. These water purifiers do not require running water or electricity and are hence the perfect options in areas with a scarcity of water or electricity. The water obtained from gravity-based water purifiers is safer than chemically pure water and better than boiled water.

Types Of Gravity Based Water Purifiers

Gravity-Based Water Purifiers are of two kinds, namely- Gravity Based Candle Filter Water Purifiers and Gravity Based Water Purifiers With Chemical Capsule. You can go to the links to read more about them.

Buyer’s Guide For Gravity Based Water Purifiers

Go through the following factors before buying a Gravity Based water purifier for your home. These points will help you make the right choice.

Purification technology and Filters

Most water purifiers that are gravity based comes with an activated carbon filter that removes the harmful pesticides along with a UF membrane that blocks the coarse particles and disease-causing micro-organisms. On the other hand, specific model, especially the HUL Pureit comes with a GermKill kit that includes an activated carbon filter, a germ-kill processor and a polisher that removes bad taste and odor from the water.

Thus, it is essential to test the quality of water and then choose a Gravity-based water purifier with a purification technology that is best suited for the water you are supplied. Go for this water purifier type only if the TDS content in the water is low.

 Capacity

The overall capacity of this type of water purifier is divided into two compartments. The top compartment usually holds the raw water that is to be purified while the lower compartment stores the purified water for the ready availability of drinking water.

It is necessary to choose a storage capacity, which is sufficient for the size of your family. The combined capacity of your water purifier should be in the range of 18-23 Liters.

Tank Type

The type of tank is also a significant factor of a gravity-based water purifier. Ensure that the water purifier you purchase comes with a transparent tank made of ABS food grade non-toxic plastic or 304-grade stainless steel.

Both of these materials of construction keeps the water safe as well as increases the life-span of the water purifier model. Moreover, a transparent tank allows you to know the level of water in the tank.

Purification Rate

The purification rate should be at least 9-12 liters per hour. This ensures ample amount of purified drinking water for the average family size. Thus, it is important to check the purification rate and choose a product as per the size of your family.

This ensures that there is no shortage of drinking water throughout the day and prevents your family from having to wait for drinking pure water.

Auto-Shut Off

An auto-shutoff feature is an added advantage which you should consider while purchasing a gravity-based water purifier for the first time. This feature automatically stops the flow of water when the cartridge or filter life expires. This ensures that you are always provided with safe drinking water or no drinking water.

Warranty and after sales service

A brand does play a part when it comes to purchasing any water purifier product. The minimum warranty of a gravity-based water purifier should be six months-1 years. Go for a brand like Kent, Eureka Forbes, or HUL Pureit which offers the best warranty and after-sales service.

Ease of Cleaning

Maintaining the hygiene of your water purifier is important. Gravity-based water purifiers require regular cleaning so that the water you drink is always safe and clean. Thus, go for a water purifier that is easy to clean using just liquid soap and running water. However, you should always use purified water for cleaning the tank.

Design

Gravity-based water purifiers are placed on the kitchen counter and are always visible to people visiting your home. Thus, a sleek, elegant, and space-saving design is the perfect blend for your modern kitchen.

Moreover, go for a model with a high base stand that provides support and easy positioning of the glass while drawing water. This adds to the convenience. It is also necessary to go for a break-free resistance tap for its longevity.
