Recently the trending water purifiers are Gravity based water purifiers, these water purifiers are the best way to purify any kind of nano impurities also in the water, they won’t use any kind of electricity, they only uses some activated carbon or UF. So in this article, we are going to discuss about the mechanism of purification of gravity based water purifiers and the best Gravity Based Water Purifiers which are available in the present market.

MECHANISM OF PURIFICATION IN GRAVITY BASED WATER PURIFIERS
- In Gravity based water purifier’s water will be filtered through a normal gravity process, i.,e from higher point to the lower point and this will be done without the help of any kind of external forces.
- Water will flow from the top container to the lower container naturally. Usually for filtering, they depend upon micro fiber mesh, activated carbon filtering and some kind of polisher which removes residual chemicals.
- Apart from just these modules, some gravity based water purifiers come with UF technology as well. This has basically another filtration process using UF Membrane.
- Activated Carbon in water purifiers removes many dangerous organic chemicals like pesticides which may be present in the water.
- Activated Carbon in water purifiers also removes chemicals in water which cause water to taste bad.
- So it is good to have an activated carbon water filter purifier for drinking water.
FEATURES TO BE CONSIDER WHILE PURCHASING A GRAVITY BASED WATER PURIFIER
- Purification Process: Before considering a water purifier one must know which kind of water supply you are having. If your area water which was very saline or hard, with the TDS or you need to get drinking water from the bore-well, hand pump or tube-well then you need to purchase a reverse osmosis (RO) based water purifier. This particular technology was innovative & also proven as very effective in removing all the impurities from the water. In RO based appliance the membrane should be .0005 microns then it will be very successful in removing all the germs, bacteria & foreign particles and also improves the taste of water also. If you getting regular clean water from the municipal facility, then you can choose a kind of water purifier with an activated carbon or UV, this purifier won’t work on the flavor of the water, but it will cleanse the water to the perfection.
- Power free or power based: In urban homes where there is no electricity fluctuations or supply of the power is relatively regular when compared with the rural homes, then the RO & UV water purifiers will be suggested because of the effectiveness in purification process & also ability in tackling wide range of dissolved impurities & also infection causing germs. But these water purifiers are not good in the rural areas since the absence of continuous electric supply or any areas where there is no continues power supply, these appliances will have no use. The compact activated carbon based water purifiers are the best choice for those who are living in rural areas or who travels frequently, because of portability of these kinds of water purifiers.
- Wall Mounted or Counter-Top: A best type of water purifier for any homewill be portable as they are counter-top models or even they can fixed to the walls. These wall-mounted water purifiers will occupy minimum or less space in the kitchen, and the counter top can be carried anywhere in your house or when you are going to small picnic. So based on your requirement you can choose in these types.
- Storage capacity and flow: Choice of the water purifier will also be based on the storage capacity also. The storage range of a water purifier varies between 4 – 25 liters. You can choose the purifier according to your family requirements. Another factor which is to be considered was how fast the water comes from the tap. This particular criterion was the most important criterion, before choosing the best water purifier in India.
