What negatives must you be aware of? The spigot on the water filter can be a little awkward. It’s fairly high, which makes getting water out at the bottom quite difficult.

What negatives must you be aware of? There is very little to dislike about this gravity water filter.

What do we love it for? You can’t argue with the results from the filtration as the water you get is crystal clear and tastes great. It filters through quickly, and this model ideal for those areas where the water quality is very poor. It’s also very easy to use and does its job perfectly thanks to its ceramic pre-filter and main multi-stage filter.

Things to Consider

There are many different types of gravity water filters which are all useful in their own ways. It’s important to look for the one that most closely matches your requirements, whether that is a water filter for your countertop or a camping trip. In this buying guide, we’ll go through all the key features that you need to consider to find out how they relate to you. You shouldn’t be left in any doubts, but our FAQs should be able to clear up any nagging concerns.

Advantages of gravity water filters

There are many great reasons to use a gravity water filter, and here, we’ll look at some of the most important ones:

Reliability – There is very little that can go wrong with a gravity water filter. They have a very high level of reliability, and all you need to do is change the filter every now and again.

Ease of use – They are usually very easy to use, and you can simply fill them up and then open the spigot to fill a cup.

Efficient filtration – The filters usually seen with gravity water filters are usually high-quality and allow you to have great water taste. They are also simple to replace and are fairly inexpensive.

How to pick the best gravity water filter

8 Best Gravity Water Filters – Get Rid of All Harmful Contaminants!

While water filers might look the same, they are all different in their own way. You don’t want to get a model that to too big or not right for your needs, for example. The perfect gravity water filter for one person may be totally different from the perfect one for someone else. In order to make the right call, it’s a great idea to read through each segment and make a mental note on how it applies to you. Once you do that, you’ll develop a clear picture of what you need.

Filter capability

Different filters will remove different things. Some people don’t like a filter to remove everything, as some of the minerals water contains can be beneficial. Also, if you’re only filtering water from the faucet, then you’ll have less need to get rid of parasites and bacteria as these would have already been removed when the water had been treated. Conversely, if you’re camping and using a natural freshwater supply, you want to get rid of them.

The Santevia Gravity Water System is a great example of a highly effective filter as it works in all situations as it gets rid of fluoride, chlorine, microplastics, bacteria, parasites, and odors. All the filters we’ve looked at here will make your water safe to drink.

Tank capacity

How much water do you need? Well, if you want a supply for the whole family, then your requirements may be quite high, but if you’re living on your own, tank capacity won’t be a huge concern. It was once said that you should drink 8 cups of water a day, which equates to around half a gallon, to give you a guide.

The Doulton HFK Household Gravity-Fed Water Filter is an example of a model with exceptional capacity at 4.2 gallons, which makes it a fantastic emergency water supply, a filter for the whole family, or both.

Filter life

You don’t want to change your filters too often. If you have high water requirements, you want a filter than can process a lot of water, such as the Travel Berkey Gravity-Fed Water Filter, which is able to get through 6,000 gallons before it needs replacing.

It’s important to factor in the cost of filter replacement. If you need constant replacements, and the cartridges are expensive, then this can vastly increase the ongoing cost. Most of the filters for these models are fairly cheap, but it’s good to check that out before buying the main unit.

Flow rate

Each filter is going to let the water through at a different rate. It’s important to have patience with this as water that rapidly passes through a filter simply isn’t going to be processed enough. All filters need a certain amount of time to get the job done.

The Santevia Gravity Water System is a good example of a filter that works fairly quickly while still having a good performance level. Others can be a little slower, but they may need that time to capture the smallest particles.

Reservoir material

As far as safety goes, there is no difference between reservoir material types. Regardless of material, all of the filters on this list comply with the highest safety standards.

Aesthetics can be an important factor as some may love the idea of having a glass reservoir, such as we see with the ZeroWater 40-Cup Ready-Pour Glass Dispenser. As for the plastic reservoirs, they can also look great. On top of that, plastic models have the benefit of being much lighter.

If you are looking for ultimate durability, you can go for stainless steel models to take with you on your trip.


Before you get a gravity water filter, you must know where you’re going to put it. Many people will get a filter only to realize that it’s too big or small for their designated space. This can be especially important if you want a filter that you can travel with.

If you want to get a compact model, then the Nikken Waterfall Gravity Water Filter System can be your perfect companion. It has a good tank capacity and doesn’t take up much space.

Check the product dimensions before purchasing to ensure that it will be a perfect fit.


If you intend to leave your filter permanently on a countertop, then the weight isn’t going to be an issue. The ZeroWater 40-Cup Ready-Pour Glass Dispenser is very heavy when filled, but it’s designed to be a permanent fixture on a countertop so you won’t move it regularly.

If you’re looking for portability, then you can go for plastic or stainless steel models, as this will ensure the product’s durability and light construction.

If a filter has a large capacity, you also need to consider how heavy the whole unit will be once it’s filled.


The prices can vary quite a lot with the Nikken Waterfall Gravity Water Filter System having supreme quality at around $400. At a little over $200, you can find some great stainless steel travel filters, such as the Travel Berkey Gravity-Fed Water Filter.

At around $150, there are examples of fantastic water filters, such as the Santevia Gravity Water System, which gives you great-tasting water time and time again. Still a bit much for you? If so, the ZeroWater 40-Cup Ready-Pour Glass Dispenser is an incredible value for money at around $60.


We all know that bottled water is ridiculously expensive. While buying one bottle may not seem like a big deal, it all adds up. If you buy one bottle of water per day at around $2 on average, then over a year would add up to more than $700. These costs can be increased if you’re buying bottled water for numerous family members.

In that respect, gravity filters can save you hundreds of dollars a year. You also have to consider the environmental impacts, too, as these filters are going to prevent you from needing to recycle hundreds of bottles. It’s that combination that makes gravity water filters a great idea.

One of the best aspects of a gravity water filter is that they need a very minimal maintenance amount. The filters are incredibly long-lasting, and you’ll most likely be replacing this once it reaches the end of its life.

As for the reservoir, there can be a bit of a buildup of grime over time, but this can usually be removed with a quick clean of soap and water. Cleaning these models is very simple, which adds to their level of usability.

To remove all the minerals from the water, you’d need to either use RO systems or distill it. A gravity filter doesn’t use either of these methods. While minerals in your water may not sound nice, they can actually improve the water quality and taste.

The examples of these minerals are calcium and potassium, which can positively affect the body. An activated carbon filter will react with all of the nasty things that can be found in water while leaving the minerals alone. Some filters can even mineralize the water.

Our Verdict

There are many great water filters here, but we still think that the Travel Berkey Gravity-Fed Water Filter is a winner thanks to its build quality and water taste improvement. It’s designed for traveling, but can easily be used in the home. You can’t go wrong with it, and it will give you great results time and time again.

As an affordable model, we have the ZeroWater 40-Cup Ready-Pour Glass Dispenser. It boasts a no-drip spigot and comes with a water quality meter.

If you want an attractive countertop model for your kitchen, then the Nikken Waterfall Gravity Water Filter System will be a perfect choice that features multiple filtration stages. On top of that, it normalizes the pH value.

While these are three great options, all of the models we’ve looked at here are brilliant. Once you find the best gravity water filter for you, you’ll enjoy crystal clear water with enhanced taste.
