The Best Gravity Water Filters to Reach Your Hydration Goals

Writen by Ronald Brown

Fact checked by Natalie Bridges

best gravity water filter

The best gravity water filter is a water filtration system that uses gravity force to push the water down while it filters. It is easy to use and efficient. However, there are many gravity filters on the market. They are available with different features that make them more useful. To help you in the selection process, we have prepared a buying guide that highlights excellent picks which have superb features. We’ve also written a guide on how to pick this gravity water filter as well as answer the most common questions about this filter.

  • Impurities Removed: It is easy for companies to label their gravity water filters as effective in removing “so-and-so” water contaminants. It is another thing for the product to have an NSF certification to support its claims. If NSF is unavailable, WQA certification is enough.
  • Filtration Rate: Filtering contaminants without pump-mediated water pressure is time-consuming. Unsurprisingly, gravity water filters take longer to process liquids. Hence, a 3L/minute option is more efficient than a 1.5L/minute one.
  • Filter Lifespan: Although filter longevity depends on water quality and consumption, homeowners should always pick a gravity water filter with a higher capacity to improve its lifespan. Choose a 5,000-gallon unit instead of a 2,000-gallon filter.

After reading, we’re hoping you can choose the gravity water filter that fits your needs and requirements.

4. Travel Berkey Gravity Water Filter

If you still have not found a gravity water filter that suits you and you think would fully satisfy your needs, you might want to look at the Berkey gravity water filter. Berkey, as mentioned, is a reputable brand in the industry known for its top-rated products that not only looks great but also functions well for the customers’ satisfaction.

One of the reasons why I prefer and why a lot prefer a Berkey gravity water filter is because of its powerful purification.

5. Platypus Gravityworks Water Filter Kit

Some cannot decide between the Platypus GravityWorks and the Purewell water filter for their next adventure. I can offer several reasons for ditching the latter for the former.

First, this portable kit is perfect for trekkers, backpackers, and other outdoor enthusiasts. It is a complete system with separate bags for “dirty” or unfiltered water and “clean” water. There are no worries about contaminating the filtered fluid with stuff from the other compartment.

Second, the microfiltration unit has the backing of the Environmental Protection Agency (EPA) and the National Sanitation Foundation (NSF). Hence, when the product says it can remove 99.9% protozoa and 99.9999% cholera, E. coli, salmonella, and bacterial cysts (cryptosporidium and giardia), I believe it.

I understand some people’s apprehension about microfiltration’s impact on flow rate. That is the third reason why I recommend this gravity water filter. It can deliver clean and safe drinking water within 2.5 minutes of filling the “dirty” bag. Its 1.75-liter/minute flow rate is also better than my current portable water filter.

Although this gravity filter only features polyethylene, it is tough enough to withstand the most rugged adventures. Moreover, I am glad its microfilter is replaceable, allowing me to continue enjoying the system’s 1,500-gallon capacity.

I like the plastic material because I will never worry about adding heft to my camping gear. The kit only weighs 11.5 ounces, and campers do not need to wait long to get their drinks because this kit is a cinch to use.

I do not have issues with this NSF-certified product, except for its peculiar drain port placement. Most gravity filters have an opening at the center bottom to facilitate easier drainage. This product positioned the port in the corner.

This gravity water filter is a nifty system for campers, emergency preppers, and outdoor adventurers.

What We Like
  • Separate bags for dirty and processed water
  • 5-minute filtration at a rate of 1.75 liters/minute
  • NSF/EPA-certified design for peace of mind
  • 1,500-gallon replaceable filter
  • Portable and easy to use, sturdy and light
What We Don’t Like
  • Bottom corner-placed drain port

6. Big Berkey BK4X2

With an established name, there are only a few that can rival the Big Berkley BK4X2 Countertop Filter. Today, it is considered as the most innovative water gravity filter for counters. What makes it reputable is its practical and enhanced filtration system.

Yes, it filters like those others available in the market. Still, the gravity filtration system uses an advanced filtration system where all contaminants are removed from the water. Hence, your outcome is just clean and safe water. Chlorine, chloramine, fluorine, heavy metals, VOCs, pharmaceuticals, and harmful microorganisms like parasites, bacteria, cysts, and viruses have no place in your body. Hence, Big Berkey does the job of purifying them.

This stainless steel water filtration goes through a 4-stage purification process and has a holding capacity of 2.25 gallons. It is more than enough for the entire family. One exciting feature of the Big Berkey is that you don’t need to plug it to an outlet to work. Yes, it doesn’t require electricity to work, so yes, you are looking at saving a lot of money on energy bills.

The filters are long-lasting too. Each filter is made of carbon and can purify up to 30,000 gallons of water, which is roughly two years of non-stop filtering. Take into consideration, though, that lifespan might go down depending on the kind of water you have. The dirtier it is, the lesser longevity of your filter will have.

Although it’s called big, the unit is straightforward to transport so you can bring it with you anywhere. It is made of stainless steel, and it is very user-friendly when it comes to setup and installation. Surprisingly, it also requires very minimal maintenance. For everything, it has to offer and with its superb performance and quality, expect it to be an expensive investment.

Overall, this is a great purchase, and you will never regret having this in your household. If you want quality performance and safe water for the whole family, then this is the countertop water filter system for you. It is reliable that you might have read about it when reading Alexapure vs Berkey
What We Like
  • Advanced filtration system
  • Maximum of 30,000 gallons of filtered water before filter replacement
  • Cost-efficient
  • No electricity required
  • User friendly
What We Don’t Like
  • Expensive cost

By the end of the process, when you are already drinking that water, you will realize that healthier, safer, and high-tasting water is real.

The top-quality countertop gravity water filter system effectively removes odor, eliminates bacteria, and reduces the harmful contaminants found in tap water. It takes advantage of the pH level to slightly alkaline and releases essential minerals naturally. Zen Water is all about the promotion of natural processes, so just maximizing gravity, it can transform any tap water to produce spring-like mineral water. The water filtration materials are also all-natural like maifan mineral stones and magnetic spigots. There are no synthetic substances or chemicals used in the entire process.

The filter chamber is designed to be transparent, so you look inside to satisfy your curiosity. A filter can also completely purify 500 gallons of water before a replacement needs to be installed. With its user-friendly and convenient approach, assembly and maintenance are also hassle-free.

You don’t need any plumbing, and no other tools are required. It is also conveniently portable. If you need to go for a family picnic, a little baseball adventure down the park, or anywhere, you’d be going, and you want guaranteed clean and safe water. Just bring this along without any drama.

With this countertop water filtration system, you also reduce costs immensely. Forget about the need for bottled waters and reduce your energy bills as well. The whole system is affordable too, which makes it a practical buy, especially those who are budget-strapped and budget-conscious.

The only hiccup to this gravity filtration system is its plastic construction. The plastic construction is not a deal-breaker in any way. This is still a good buy, and if you are keen on having that all-natural, clean, and safe water, then better ring up this purchase soon. Overall, you might have read about this product when reading independent laboratory testing results of popular gravity water filters.
What We Like
  • 5 stage mineral filter
  • All-natural system sans the chemicals or synthetic substances
  • Maximum of 500 gallons of filtered water before filter replacement
  • Hassle-free assembly and maintenance
  • Cost-efficient
What We Don’t Like
  • Plastic construction

8. Berkey Light Gravity-Fed Water Filter

Berkey, an established company that produces clean and safe water, has yet again solidly reminded us why they are the most suitable choice with the Berkey Light with 2 Black Filters and 2 Fluoride Filters.

Of course, it filters, but it has Fluoride and Arsenic reduction elements that are responsible for absorbing the unwanted items that are in tap water. It is also the USA’s pride as every part is made and drawn together in the USA.

The materials used in this product are all safe and BPA-Free Copolyester, which does not leak nasty-tasting plasticizers or substances into your H2O. This is also highly recommended for families, as it has a maximum storage capacity of 2.75 gallons. Before replacing the filter, it must process 6,000 gallons of water first. It gives you tons of savings as there will be no need for any bottles. All Black Berkey elements are also self-sterilizing and completely re-cleanable, adding savings to your accounts.

This product is as good as a Propur water filter. It is also proven to be virtually unbreakable and shatter-resistant while working slowly on the background. It can filter up to 4 gallons of water in 60 minutes, and you are guaranteed water free from MS2 and FR Coliphage by up to 99.99%.

It removes harmful chemicals like pesticides, herbicides, VOCs, radon 222, organic solvents, and trihalomethanes. Your water will also have no bad taste or nasty smell, so you will be more enticed to drink more, keeping you hydrated throughout the day. It results in a healthier you with glowing energy and a youthful glow.

However, this water purification system is top-rated and recommended for those whose water supply is not salt water. It is the only opportunity of the Berkey Light with 2 Black Filters and 2 Fluoride Filters because it cannot be used with saltwater. Knowing your water sources and what kind of water you have in your homes or in the area where you will bring this product alone is critical in a successful filtration system. This would still work, and you can still enjoy the benefits because, most of the time, you won’t be dealing with saltwater.

You can either use it as your straw since it comes with a soft bottle, as an in-line filter compatible with most hydration packs, with a gravity system, or as attached to a disposable container of your choice.

This becomes a staple filter system because you need safe and clean water anywhere you may be, making it so convenient. After all, wherever you are, you can get that water.

It is more than capable of removing bacteria up to 99.99%. Parasites like E-coli, Giardia, and Salmonella are also eliminated alongside heavy metals like Lead. It doesn’t matter if you are going camping or you are going to an international and remote destination. This system gets the job done each time. For your added peace of mind, it exceeded the US EPA drinking standards and the NSF 53 standard.

If you are planning to be away for a while, no worries because LifeStraw Flex’s microbiological filter can clean 500 gallons of water. It is more than a year’s worth, and the disposable carbon filter can process 25 gallons of water, roughly three months of consumption.

The bottom line, this is a great buy and a smart one, especially for those folks that are always on the go.

What Is A Gravity Water Filter/ Who Is This For


A gravity water filter is a type of water filtration system that relies on gravity for the filtration process. The force of gravity pushes the water down into a filter to remove any particles, sediments, contaminants, pollutants, and other impurities.

Once it’s done, the filtered water passes through a holding chamber. You can access this water depending on the style it has. Home versions of gravity water filters usually have spigots or spouts for your countertop. You can also choose a pitcher-style if you like. There are also versions suitable for outdoor use such as camping, hiking, backpacking, etc. These versions are usually light, and you can either hang them or place it inside your bag.

A gravity water filter is also a great add-on to your current water filtration system. It can work well with any filter method such as reverse osmosis systems, distillation, charcoal filters, and the like.

Having your very own water filter is recommended for those who want to try their hand in water filtering. This portable device is small and easy to use, making it an excellent place to start and learn the basics.

Gravity water filters, such as gravity water filter backpacking, are also useful to have when you live in an area with low-quality tap water. With the filter, you can have a consistent supply of clean and safe water.

It’s also quite useful to have a gravity water filter during emergencies. Since it doesn’t need electricity to operate, you can still have a fresh supply of clean and safe water for you to drink.

How Does It Work

The gravity water filter was first speculated to be made in 1800 in London, England, by craftsman John Doulton. During this time, England had numerous water-related problems. As such, Doulton and his team decided to create a water filter case packed with powder carbon.

When Queen Victoria heard of this, she was impressed and even requested the team to create these filters for the Royal household. When that happened, their water filter became a huge hit and remained quite popular even until now.

As in its name, the gravity water filter relies on the force of gravity for its whole filtration process. Gravity is there to push the water to go through the filter and eliminate it all its pollutants, chemicals, contaminants, particles, and other impurities.

The gravity water filter is a simple device and, thus, only has a few parts to function. It just comes with two chambers and a filter media or membrane.

The first part is its upper chamber, which contains the filter media. Regardless of which filter media you choose, they all work the same way.

Once the water passes through the filter media, the filter’s numerous microscopic pores then act as a barrier. As such, particles and sediments bigger than those pores cannot pass through and move to the next chamber. In this case, only clean water can pass through, leaving all its pollutants and other impurities behind.

The clean and filtered water then travels to the lower chamber and stays there. You can access your water depending on the type of design it has. Some gravity water filter models come with faucets or spigots, while others come in a pitcher-type design. You also have models that are great for camping, backpacking, and other outdoor activities.

What Are The Different Types Of Gravity Water Filters


Before you purchase a product, one of the most important considerations is the different types of products available in the market. With this, you’ll know which can suit your needs the most.

The gravity water filter is no different. Like anything, it also comes in various types, styles, sizes, and the like considering that it’s quite popular nowadays. This section will list all these differences for you to help you out in the decision-making process.

Ceramic Gravity Water Filter

Ceramic gravity water filters are one of the many home versions of the gravity water filter. Since they are made from ceramic, they are quite suitable for those who are sensitive or allergic to certain chemicals.

Despite its look, it functions as a standard gravity water filter. You need to put the water inside the chamber, and it will do the rest.

Keep in mind, though, that since it’s made of ceramic, it needs a little extra care and maintenance.

Frequently Asked Questions (FAQs)

Nikken vs Berkey water filter? Which is better?

Nikken and Berkey are two of the top-selling gravity flow water filter systems. Choosing between these brands can be challenging, especially for first-time users.

Most homeowners consider Berkey systems better than Nikken products. They cite several reasons.

A portable Berkey water filter removes 99.9999% chlorine, sediments, pesticides, bacterial cysts, and solvents while reducing viruses by 99.99999%. The system also reduces heavy metal concentrations in the water.

On the other hand, Nikken filters for home applications can only remove bacterial cysts, chlorine, pesticides, sediments, and solvents without information on the contaminant percentage removed.

Berkey features adsorption, absorption, and microfiltration in its gravity filters, while Nikken only uses the latter two technologies. Berkey filters 84 gallons of contaminated water daily, while Nikken does not offer such information.

Families who are unenthusiastic about plastic products will also love Berkey systems because they feature 304 stainless steel. The two-year warranty offers greater peace of mind to homeowners than Nikken’s 12-month guarantee.

Surprisingly, Berkey gravity water filters are more affordable than Nikkens, despite having better filtration capabilities and more robust construction.

How long do gravity filters last?

A gravity water filter can comprise several filtration elements, each with a different lifespan. For example, the Santevia stone gravity water filter features a ceramic pre-filter, a five-stage filtration system, a fluoride filter, and mineral stones.

The pre-filtration unit can last 12 months, while the mineral stones can continue filtering the water for up to two years. Meanwhile, the fluoride filter might only last four months or about 317 gallons, whichever comes first. The five-stage filter unit has a six-month lifespan (about 475 gallons).

It is worth noting that water consumption and quality can impact filter lifespan. The dirtier the water (more water impurities) and the higher the water consumption, the shorter the gravity water filter’s longevity.

Why is it important to change the gravity water filters?

As in any other filtration system, timely replacement of gravity water filters is necessary to maintain optimal functioning.

Sediments and other particulates can accumulate in the gravity water filter and obstruct the pores where water and other molecules pass. Clogged filter holes can reduce water flow, so it takes longer to fill a container with filtered water.

Blockage can also damage the membrane and allow water impurities to pass through. Hence, you will notice an unpleasant taste and smell in your drinks. The liquid can also look hazy or cloudy.

How often should you clean your gravity water filter system?

A gravity-fed water system has several components with varying cleaning frequencies. For example, the ceramic pre-filter requires weekly scrubbing of the surface with an appropriate cleaning sponge.

Meanwhile, mineral stones require boiling for at least a minute every four to six months to kill unwanted germs and to “recondition” them. Be careful not to use scented fabrics to dry the mineral stones because they can absorb the odor.

As for the five-stage filter or fluoride filtration unit, this component does not require cleaning, only replacement every four to six months. However, you must clean the gravity water filter’s other parts to ensure proper functioning.

Manufacturers of filtration systems have specific recommendations for cleaning and maintenance frequencies. You might want to read your owner’s manual to learn how often you should sanitize the product, including what cleaning materials to use.
