This will save you so much money in the long run, the savings on filters will pay for the Berkefeld by themselves.

  • Easy to carry around

Things To Consider Before Buying 

When it comes to searching for the gravity water filter for you, there are a few features you should keep an eye out for. It is not as simple as you think, features such as weight or size can actually determine if the gravity water filter is more suitable for an everyday use in a home, or if you can take it with you. Pay close attention so that way you will know exactly what to look for before buying one.


Gravity water filters come in many different sizes, and can range from a lightweight 5 lb to more substantial 10 – 15 lb. If you plan on leaving the water filter on your counter, then the size will not be a very big issue for you, but if you plan on camping or taking the system on long trips, you should consider how large you want the product to be.

The best way to do this is to figure out your typical camping setup and determine how much room you can afford in your standard gear. Also, keep in mind the number of people going with you, or the number of days. Based on how many people there will be, a bigger or smaller sized filter is better.

Tank Size

Typically, most gravity filter tanks will be over 2 gallons, but there are smaller ones that you can find as well. If you need to store a large amount of water at a time or are trying to provide water for multiple people you need to take into account just how much water the gravity filter can hold. You don’t want to have a tiny tank.

On the other hand, there is no point in hauling a huge water tank if it’s just you on the trip. Therefore, if you are a solo traveler, opt for the small tank sizes that will serve your purposes quite nicely.

Filtration Time

Another feature that you should take into account is just how fast the water can filter through the system. Depending on the type of filter the system is using, the filtration times can be drastically different.

The truth is that the less time is usually more convenient, but if you are only using it at home, it is not as relevant. However, keep in mind that the slower the water comes out, the better it’s purified.


Stainless steel tanks are the ideal material used to construct gravity water filters, but many other filters use plastic and other materials for the water tank. If you plan on traveling with the system you want to make sure that you get a stainless steel tank. Whereas if you are going to keep the system in one place any of the other materials will work perfectly fine.

Think ahead, if you are on a camping trip, moving around constantly, is it a good idea to take a ceramic filter? Probably your best shot is a stainless steel one. They are unbreakable and weigh much less.

Filter Type

Decide on what type of filter you would prefer, and what level purity you are looking for from your water filter. There are five different types of filtration systems or types: distillation, ultraviolet, ceramic, catalyst converter and reverse osmosis. Each one has a different level of purity.

Deciding which one suits you better, is a very subjective decision. However, we explain them in detail below so you can then choose on your own.


By heating up the water to extremely high temperatures, and then collects the steam that results from evaporation and filters that into drinkable water.

While this is an extremely effective method, it is difficult to set up in any consumer application unless you are quickly putting something together in an emergency setting.


Ultraviolet purification is one of the most effective forms of purification, killing an enormously high percent of germs and bacteria with UV rays. These devices tend to be extremely expensive and are therefore not practical for every person. 


Ceramic filtration involves a form of osmosis, which pulls the water through pores that filter out bacteria and germs. This is the oldest known method of water filtration and is still quite effective at removing most impurities from water. These forms of filters are common in gravity water filters.

 Catalytic Converter

Catalytic converters work by neutralizing the harmful elements of your water for a short period of time. The issue with these systems is that the water needs to be drunk immediately, otherwise the water will again become impure.

 Reverse Osmosis

This method of filtration uses pressure to push water through a membrane that removes impurities and minerals from the water. The water can then be stored and remains usable for an extremely long period of time. This is the typical method that is used by gravity water filters.

Now that you know the features to consider before buying, it’s time to explore the best gravity water filters.

6 thoughts on “The Best Gravity Water Filter: Clean Water, Wherever You Go!”

  1. Finally I can drink my tap water! (well, once it’s filtered through the British Berkefeld anyway…) Always steered clear of tap water and instead was spending a small fortune on bottled water. Did consider buying a filter water bottle but there weren’t any that were big enough to meet my needs. Each night I top up the Berkefeld and then I’ll refill it as and when I need to throughout the day. Easy for the whole family to use and is – thankfully – a lot quieter than the fridge door water dispenser!

  2. Think how you’ve saved the planet by also ending the consumption of plastic bottled water. You’ll get goosebumps once you’ve seen the amount of plastics we use – and can’t even recycle! Having filtered water at home is a step in the right direction of protecting what’s left of Mother Earth.

  3. In trying to raise the pH of the water I was drinking at home, I finally settled on the Zen Water Filter. Quite a few of the reviews spoke about the water being tasteless, which it’s not, however the water does taste incredibly crisp. Does take a while to setup to begin with, but you must let it run through the process. The mineral stones need to be boiled whilst the water needs to run through the filter until clear. It takes time, yes, but it is so worth it when it’s done! The pH is rising slowly but surely!

    • The Zen Water Filter is an excellent drinking companion. It produces clean and potable water for the least price. I don’t know how someone can say that the water is tasteless, probably they meant it has no peculiar taste like that of rust. With water filters, it is important that you let it finish the process for your water to be safe.

  4. I have an AquaRain 4 filter and love it, but want to start filtering out fluoride. Are the filters for the other brands compatible?

  5. Hi Hether! Based on the Amazon page of AquaRain, they wrote that the Berkey Flouride filter MIGHT work. They also informed users that they are coming up with their own version of their flouride filter sometime in May.
