So you’ve decided that your current water filters just aren’t cutting it. In all honesty, I can relate. I’ve been there too. I bet you feel like you’re drinking from a fire hose because your water is so chlorinated.

Do you know what is in your tap water? Is it safe to drink? All the research points to “no.” Bottled water may not be a sustainable solution for everyone, and it can be pretty expensive.

Fortunately, there are some gravity fed water filters that are an affordable, sustainable solution that will keep your family safe from the contaminants in your water.

I researched the top 5 gravity fed water filters to find out which one will best meet your needs.

1. Big Berkey countertop gravity water filter system

Big Berkey countertop gravity water filter system

Check out the best-selling Big Berkey if you need a larger filter to sit on your countertop. This set includes two filter elements, each of which can handle up to 3,000 gallons of water.

In this case, the package also contains two additional fluoride elements. Each of these is attached to the stem of the black purification element and has a capacity of 1,000 gallons.

The system will eliminate parasites, cysts, and bacteria while lowering nitrates, nitrites, mercury, and lead levels. It will also target harmful chemicals such as pesticides, herbicides, and organic solvents.

The material used in this construction is polished 304 stainless steel. It’s stylish enough to be on display in your kitchen at all times.

It has a diameter of 8.5 inches, which is still small in terms of its countertop footprint and a height of 19.25 inches. When deciding where to place them, keep an eye out for wall cupboards or shelves. Because of its larger dimensions, it can hold 2.25 gallons.

The filtration rate is approximately 7 gallons per hour. It works best when the upper container is full, as with other gravity systems.

You’ll also notice that it slows down as the filter gets older. Re-priming the filters with the included rubber washers can help speed things up again.


  • Large 2.25-gallon capacity
  • The two main purification elements will each treat 6,000 gallons
  • Fluoride filters are included as standard.


  • For the best results, regular maintenance is required.
  • It must be used every day, or the filters will grow bacteria.

2. Propur traveler countertop gravity water filter system

Propur traveler countertop gravity water filter system

Lead, microplastics, chlorine, and fluoride will all be removed by Propur’s water filter.

This is at the low end of the gravity water filter spectrum. It has a capacity of 1.6 gallons and is best suited for use by one person. It measures 18.5 inches tall and 7.5 inches in diameter to fit neatly, even in small kitchens. Its small size also makes it convenient to carry about.

It’s made of polished 304 stainless steel and is sophisticated enough to be displayed at home. It’s also tough enough to be used in the great outdoors. If you get caught in the rain, it won’t rust.

However, we’ve heard that the knob used to lift the lid is a design flaw. Don’t be tempted to overtighten it; you might snap it off.

The filters are intended to last six months or 300-400 gallons. The exact time will be determined by how contaminated your water source is. They work with tap water and rainwater, and water from lakes, streams, and rivers.

However, keep in mind that this is a system intended for everyday use. As with most gravity systems, if the filters dry out, they can become bacterial breeding grounds.

Although the filters, in this case, are infused with silver to help inhibit bacteria, we wouldn’t take any chances. So, if you haven’t used it in a while, make sure you thoroughly clean the system and replace the filters.


  • Small size is ideal for small spaces and camping.
  • Filters imbued with silver to impede bacteria growth
  • It can filter rainwater, tap water, and water from rivers and lakes


  • We’ve heard people complain about the fixture needing to be cleaned.
  • Be careful of the knob on the lid of the upper canister – it has been known to snap off.

What is a gravity-fed water filter?

Do you live in a rural area where there isn’t a consistent supply of water? Or is the water provided unsafe for you and your family? Or do you enjoy camping or traveling to places with no clean water and struggling to obtain fresh and pure water for your consumption? Then don’t worry because we have the solution to your problems: gravity-fed water filters. The gravity-fed water filter is a filter that can be used to filter water from anywhere, even the most remote locations. It’s portable, so you can take it with you when you’re on the go.

What is the function of a gravity filter?

Activated carbon is used in gravity-based water purifiers. How so? When water is purified and filtered, the activated carbon absorbs impurities in the unclean water. The other benefits become apparent when you consider the ease of use and natural purification.

You have environmental advantages. Because there is no need for electricity, you can use hollow fibers with the filter. Why is this so? In essence, the water passes through hollow fibers and picks up impurities before being filtered.

As a result, gravity water will have an upper attachment for storing water, a lower attachment or storage area for storing purified water, and a mediator with filter elements in between for processing.

As a result, the force of gravity will eventually push things in the water through. As a result, water will flow from the upper attachment to the lower attachment, moving through the filter elements as it goes. These filter elements trap impurities with millions of microscopic pores, allowing only water molecules to pass through. In a gravity filter, this is how water is purified.

A buyer’s guide to choosing the best gravity-fed water filter

As is customary, before embarking on your quest for a high-quality water filter, you should be aware of what to look for. When purchasing a water filter—in this case, a gravity-fed water filter—there are a few things to keep in mind and keep an eye out for.

  • Construction material – make sure the filter you buy is made of stainless steel. Because it is rust-resistant, light, portable, and easy to clean, stainless steel is the best material for a water filter. If you intend to travel frequently with the water filter, a stainless steel one is ideal because the material is resistant to wear and tear. We’ve all heard that traveling causes wear and tear on your belongings, which you don’t want.
  • What needs to be filtered – the filtration level should be considered when purchasing a filter. To avoid getting sick and ensure that only pure, fresh, and healthy water is consumed, you must filter out all substances that may be harmful to your health. A filter capable of filtering dirt particles, pesticides, heavy metals, parasites, and other contaminants should be considered. This is due to the poor quality of the water you are receiving. If you are traveling or visiting a new location, this type of filter is ideal because you are not fully aware of the water’s substances. Consider a gravity-fed water filter with ceramic filter media and activated carbon for the best results.
  • Filter replacement – Like any other water filter, the filters installed in a gravity-fed water filter will need to be changed. The good news is that, unlike other types of water filters, replacing a gravity-fed water filter is simple and easy to do on your own. It would be best if you also considered how frequently the filters would need to be changed. Some water filter systems have filters that last up to a year. To avoid many problems, you really should consider a gravity-fed water filter with self-sterilizing cartridges containing traces of silver. This is because they are effective at preventing the growth of bacteria on the elements of the filters.
  • Amount of water required – To be on the safe side, don’t forget to factor in the amount of water that needs to be filtered. Consider your current water consumption to make this process easier. If you’re unsure about how much water you’ll need, especially when traveling, it’s best to get a larger-sized filter. If you want a filter for your home, the number of people in the house will determine the best filter size.

The benefits and drawbacks of using a gravity water filter

Like all water filtration systems, the gravity water filter offers numerous advantages and disadvantages to the average buyer. If you’re considering getting one, you should weigh the pros and cons to see if it’s right for you and your needs.

All of these will be listed in this section.


Like all water filtration systems, the gravity water filter includes a filter medium that is responsible for the filtration process.

Regardless of the type, the filter contains a plethora of microscopic pores that serve as a barrier. No contaminant, particle, sediment, or other impurities larger than the pore can pass through. This will provide you with clean water.

Enhance the taste and smell of your water

In addition to bacteria and pollutants, the gravity water filter will remove chemicals and sediments from your water. Your water supply will smell and taste better once these are gone.


Gravity water filters allow you to have clean water by simply using your tap water supply. You would no longer need to rely on bottled water with this. It reduces plastic pollution, which benefits the environment.

Reduce your spending

Gravity water filters can also aid you in saving money on household expenses. With this on hand, you can cut back on bottled water and use a reliable, durable reusable water bottles.

Furthermore, these filters do not require any electricity to function. As a result, you can save money on electricity.

Excellent for emergencies

Gravity water filters are also useful in emergency times or when there is a limited supply of water. You can have a constant supply of clean drinking water because it does not require electricity.


Filtration constraints

No single filter medium can handle all pollutants, contaminants, particles, and other impurities. The same is true for your gravity water filter.

If the model allows it, you should buy a filter medium made of a mix of materials. This allows it to deal with a broader range of contaminants and impurities.

Slow water output

The amount of water that a gravity water filter can filter is also limited. It can only sift about 10 cups per day, depending on its size.

Long filtering period

Gravity water filters, like all water filtration systems, require some time to filter. Some users may find it inconvenient because they must refill it regularly.

In conclusion

Finally, gravity-fed water filters are ideal for outdoor activities such as camping or traveling to rural areas where clean water is not assured. The good news is that they can also be used at home or the office. As shown by our top three picks, most of them are made of stainless steel, making your cleaning work easier and more portable due to their lightweight. The Big Berkey, on the other hand, is your best bet for better service. Simply dig a little deeper into your pocket, and you’re set. If you find it difficult to fill these filters daily, consider using a reverse osmosis water filter instead.
