What Is Gravity Water Filter? 

A gravity water filter is a type of water filtration system that uses gravity to draw water through a filter. The filtered water is then collected in a container for later use. 

Gravity water filters can be used for municipal tap water and private well water. They are an effective way to remove contaminants from your water, including chlorine, lead, and bacteria. 

Gravity water filters are typically more extensive and expensive than other water filters. Still, they require no electricity to operate and can filter large quantities of water simultaneously. 

If you’re looking for an effective way to filter your water, a gravity water filter may be the right choice. Learn more about gravity water filters and how they work to find the right system for your needs. 

How Does Gravity Water Filter Work?  

Gravity water filters are one of the most popular types of water filters on the market today. But how do they work? 

Gravity water filters work by using gravity to force water through a filter. The filter is usually made of carbon, removing impurities from the water. Gravity water filters can filter both tap water and well water. Gravity water filters are typically made of two chambers, an upper chamber, and a lower chamber. The upper chamber is where the dirty water is placed. The lower chamber is where the filtered water comes out. 

Gravity water filters work because dirty water is placed in the upper chamber. The water then flows through the filter into the lower chamber. The filtered water is then collected in the lower chamber. 

Gravity water filters can remove various impurities from water, including chlorine, lead, and bacteria. Gravity water filters are a popular choice because they are easy to use and require no electricity. Gravity water filters are also very affordable. 

A gravity water filter is an excellent option if you are looking for an easy and affordable way to filter your water. Gravity water filters effectively remove impurities from water and are very easy to use. 

Different kinds of gravity water filter systems 

Countertop and hanging gravity-fed water filter systems are the two most common types. Their primary distinctions are discussed below. 


A gravity-fed countertop water filter sits on a surface like a kitchen countertop and is typically constructed of stainless steel. The most effective countertop gravity water filters are available in various sizes, with the larger filters able to filter several gallons of water at once. 


Designed to be hung from a height, hanging gravity water filters employ the same principle as countertop filters. They are typically much smaller than countertop water filters and resemble hospital IV bags, despite being much more innocent! 

During a hike or camping trip, you can fill a hanging gravity filter with water from a lake or stream, and gravity will filter the water as it flows down the tube towards the drinking cap. They tend to be significantly less expensive than countertop gravity filters, but they’re not designed for daily use, and their materials make them less durable. 

How To Use Gravity Water Filter 

There are many ways to filter water, but a gravity water filter is one of the most effective and straightforward methods. Gravity filters use gravity to force water through a filter media, which removes impurities and contaminants. 

One of the great things about gravity filters is that they can be used in various ways, making them perfect for a wide range of needs. In this article, we’ll show you how to use a gravity water filter in three different ways: 

1) Using a Gravity Water Filter as a Stand-Alone System: 

If you’re looking for a simple, effective way to filter water for your home or office, then using a gravity water filter as a stand-alone system is a great option. All you need is a gravity filter and a container to hold the water. Pour water into the top of the gravity filter, and it will slowly drip through the filter media into the container below. The contaminants and impurities will be trapped in the filter media while the clean water collects in the container. 

2) Using a Gravity Water Filter with an Existing Filtration System: 

If you already have a filtration system in places, such as a reverse osmosis system or water softener, you can easily add a gravity water filter to your setup. This can be done by connecting the output of your existing filtration system to the input of the gravity filter. This will allow the water to go through your current filtration system and then be filtered again by the gravity filter. This can provide an added level of protection and ensure that your water is as clean and pure as possible. 

3) Using a Gravity Water Filter in an Emergency Situation: 

Gravity water filters are also perfect for emergencies when access to clean water is limited. All you need is a gravity filter and any container, even a plastic bottle. Fill the container with water and then pour it into the top of the filter. The clean water will drip into the container below while the contaminants and impurities are trapped in the filter media. This can provide clean, safe water to drink in an emergency. 

There are many different ways to use a gravity water filter, making them versatile and adaptable to a wide range of needs. Whether you’re looking for a simple stand-alone system or want to add an extra level of protection to your existing filtration system, a gravity water filter is a great option. And in an emergency, a gravity water filter can provide you with the clean, safe water you need to get through. 

Benefits Of Using Gravity Water Filter 

There are many benefits of using a gravity water filter. Perhaps the most obvious benefit is that it can remove impurities from your water, making it safer to drink. Gravity water filters can also improve the taste of your water by removing chlorine and other chemicals. 

Another significant benefit of using a gravity water filter is saving you money. If you are tired of buying expensive bottled water, a gravity water filter can help you save money by allowing you to filter your water at home. 

Gravity water filters can also be very convenient. Some models can be attached to your kitchen faucet, making it easy to get filtered water whenever needed. Other models are portable, so you can take them when traveling. 

There are many different types of gravity water filters on the market, so it is essential to do your research to find the one that best meets your needs. Be sure to read online reviews to understand how satisfied other customers have been with a particular model. With some research, you can find the perfect gravity water filter to provide you with safe, clean, and delicious water. 

The benefits of using a gravity water filter are numerous. From improving the taste of your water to saving you money, there are many reasons to consider investing in one of these devices. Be sure to research to find the perfect gravity water filter for your home or office. 

10 Best Gravity Water Filter On The Market

1. Best Overall: Big Berkey® Gravity-Fed Water Filter

The Big Berkey is one of the most popular gravity-fed countertop water filters. While it is priced between $50 and $100 more than its competitors, you pay for the brand’s reputation – Big Berkey has a long history of producing high-quality countertop filters. 

You can purchase the Big Berkey with two filters, known as Black Berkey Elements, for a slightly reduced price or pay an additional $110 for four filters. While increasing the number of filters in the chamber will not improve the filtration quality, it will speed up the filtration process, doubling both the filtration speed and the total lifespan of each filter, which now only must exert half the effort each time. 

The filter is remarkable. The steel containers are durable, and the filter does better purifying water than any other system I have used. Initially, however, I had many problems with the rubber odor (like many other reviewers).  

Problematic is the rubber stopper and washers included with the system. The best action is to discard them and replace them with silicone washers.  

Also, I recently purchased four carbon filters instead of two (eliminating the need for rubber stoppers) – a more expensive but worthwhile investment (also, it fills the tank much faster that way). I also purchased the stainless-steel spigot from Berkey (which comes with silicone washers).  

I have no idea why these foul-smelling rubber stoppers are included with the system. There are numerous YouTube videos on priming the filters and cleaning the system. After a month of trial and error, it’s finally perfect! 

Key Features
  • Comes with 2 black purification elements 
  • Reduces heavy metals, VOCS, pharmaceuticals and many other contaminants 
  • Extremely durable stainless steel prevents from corrosion and will provide a long life for this system.

Factors To Consider When Choosing the best Gravity Water Filter

There are a few things you should keep in mind when choosing the best gravity water filter for your needs. Here are some factors to consider: 

Flow rate 

The flow rate is the number of gallons per minute that the filter can clean. Make sure to choose a filter with a high flow rate if you have a large family or if you plan on using it for outdoor activities. 

Filter media & lifespan 

The lifespan of most gravity filters is approximately 6 to 12 months. It is common for filter media to consist of activated carbon, carbon from coconut shells, or a similar substance. 

Activated carbon media is one of the most popular filter materials in terms of effectiveness, and its scientific process makes excellent sense. The average lifespan of a hanging gravity water filter is 500 gallons, so you will need to replace it every 1 to 2 months, depending on usage. 

Contaminants eliminated 

Most gravity water filters remove the bare minimum of chlorine from water. Numerous filtration systems can remove bacteria, heavy metals, and chemicals such as pesticides and herbicides. Some gravity-fed filters can soften water and add beneficial minerals, but this is not a standard feature. 


The design of hanging gravity water filters makes them significantly more portable than countertop water filters. They are small and portable, and their bagged reservoir design allows you to shape them to fit into a space in your backpack. When empty and not in use, they can be folded and stored away. 

Countertop filters are portable but not as portable as hanging filters. You can disassemble and stack the components to save space, but you will still need considerable space to store and transport them. 


Gravity water filters come in a variety of sizes. Choose a size that is appropriate for your needs. 

Storage Capacity 

The fact that a hanging gravity water filter is small and portable is an advantage, but it also means that this type of filter has a smaller capacity. The typical capacity of a hanging filter is one gallon. On the other hand, some countertop water filters can hold up to five gallons of water, but it would be impractical to carry these much bulkier units on a camping trip. If you intend to use your water filter solely at home, a countertop gravity filter is the best option. A hanging water filter is better suited to your needs for taking on camping trips. 

Chamber material 

Stainless steel is the most common chamber material for countertop water filters. This material prevents rusting and prolongs the freshness of water. 

Typically, plastic and silicone are used to construct gravity-hung water filters. When plastic is involved, it is essential to ensure that the product is made from food-grade, BPA-free materials. The good news is that most hanging water filters are made from such materials. 


Gravity water filters vary in price. Make sure to choose a filter that is within your budget. 

Gravity Water Filter - FAQs

If you are looking for a gravity-based water purifier, it is highly recommended that you acquire a UF-based machine. Overall, water from gravity-based filters is superior to boiled water and safer than water purified with chemicals. 

The water filtration system based on gravity is effective and efficient. It is essential and highly functional. There are various sizes available, depending on your requirements. It can be placed anywhere in the house, including on tables and countertops. 

Freestanding gravity water filters do not require electricity or a connection to a water supply. Therefore, they are an excellent water filtration method in areas without electricity or running water. 

Gravity filtration is a straightforward method for removing solid contaminants or precipitation from an organic liquid. The filter captures the impure substance. Gravity filtration can collect any solid that is insoluble. 

If you have a municipal or corporation water supply at your residence, a gravity-based water purifier is sufficient because the water is already chemically purified. These are generally safer to consume than boiled or chemically purified water. 

Suction has the potential to pull small solid particles through the filter paper pores, potentially contaminating the filtrate with the stable compound. Gravity filtration is preferred when the filtrate is retained, as suction has the potential to pull small solid particles through the filter paper pores, potentially contaminating the filtrate with the solid compound. 

Not only can it filter 4L of water in less than five minutes, but it can also be used as a shower or handwashing station. While most gravity filters must be hung, you can filter water on a slope or a rock if there are no trees or bushes nearby. 

When your filters stop working, there is no point in continuing to use them to clean your water, as they will no longer function properly. If you are filtering river water, changing your filters and ensuring their optimal performance will help you maintain good health. 

You should give your countertop water filter a thorough cleaning every two to three months. If your water has a high mineral content and limescale accumulates inside the holding tank, you should clean it more frequently. After using hanging gravity water filters on a trip, wash and dry all components according to the manufacturer’s instructions. You can also rinse it while traveling if you are away from home for an extended period. 

90% of the time, no. If a filter does this – and a few do – it will be marketed as one of its primary advantages. As with most water filters, most gravity water filters merely eliminate contaminants. If you wish to remove limescale, it is advisable to purchase a water softener. 

If you will be away for an extended period, or if you will not be using your gravity water filter, drain the water from the system and remove the filters. Allow them to air-dry, then store them in a dry, excellent location until the next time you intend to use your system. 


The gravity water filter is a great way to get clean drinking water. Be sure to follow the manufacturer’s instructions and take care of your filter to ensure that it lasts for many years. With proper care, your gravity water filter can provide you with years of clean, safe drinking water.
