What Is Gravity Filtration?

It Defines: Gravity filtration is a process of water filtration in which gravity is used to pull liquid through a filter.

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.

Gravity Water Filter Buying Guide

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.

Don’t fall for the products that are in the hype. Instead, beware of the too good to be true claims of companies. Determine your need whether you want to use the filter in home, office, outdoor, or for an emergency.

Important: Home and office needs may make you need a filter with a higher capacity and filter life. Make sure that you don’t compromise on the longevity and quality of the filter just to get a cheap one.

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.

  • Why does my filter spigot leak?

Mostly it is because the washer or nut of the spigot is either loose or too tightened up. If the nut is tight, make sure you fit it right because the spigot can crack.

  • How long does gravity filter take to filter water?

Just like any other water filter, the time of filtration in gravity filters depends on the water quality. Usually, the first filtration cycle is slow, but after that it gets normal.

  • When to change a gravity filter?

The instruction manual that comes with your gravity filter has the replacement time mentioned on it. However, you need to keep a check on your filter. If you feel that the quality is deteriorating, you will know it is time.
