What Is Gravity Filtration?
No electrical supply is needed in the gravity filtration process. This process is usually performed in chemical labs where reactions are experienced after combining and removing different chemicals.
At present, gravity filtration is the most common type of water filtration procedure because it is cost-effective and energy-efficient. Gravity filters are introduced in the markets that are composed of two chambers to remove the contamination from the water.
How It Works
Gravity filtration is an effective method to remove all the solid impurities and organic liquids from the water.
The gravity filter contains one upper and one lower chamber. When you urn on the filter, contaminated water stays in the upper chamber where the filtration is done. The water that is purified is transferred to the lower chamber from where you can use it.

When buying yourself a new gravity filter, make your decision with confidence that is based on detailed knowledge. For that, we bring you an informative buying guide. There is no doubt that you will find hundreds of gravity filters claiming to be the best, but not all of them will meet your needs.

FAQs (Frequently Asked Questions) on Gravity Water Filters
- How do I clean my gravity filter?
Cleaning a gravity filter is a breeze. Just take the filter out of the container and let it run under cold water for 2 minutes. Scrub it a little to remove dirt and assemble it again.
