A Detailed Comparison of Best Gravity Based Water Purifiers

With growing population, the demand for clean drinking water is increasing, thanks to the increasing levels of pollution. The availability of drinking water is as important as the purity of water. In India, the water supplied to households has a lot of impurities. If you get Municipal Corporation water supply which is low in TDS, you need to opt for a gravity-based water purifier.

A gravity based water purifier doesn’t need electricity to remove impurities from water. The purifiers use activated carbon or UF to remove impurities and make water suitable for consumption. The UF membrane used by the water purifiers come with hollow fibres. The impurities stick to the hollow fibres present in the membrane during the filtration process to provide safe drinking water.

Some gravity water purifiers use UF technology. The pore size of the UF membrane is 0.1 microns which can easily filters out bacteria, cyst, and other microorganisms. If you need a gravity based non electric water purifier, opt for UF based water purifiers. Renowned water purifier brands like KENT use an advanced UF technology.
