One of the most important pieces of equipment you can bring with you is a water filtration system, and today we will go over some of the best gravity water filters on the market today. Finding the best filter may seem like a challenge, but by the time you are finished reading this you will be a professional!

Big Gravity Water Filter

With the proper water filtration system, you and your family can go anywhere you desire and always have clean filtered water to drink. When it comes to outdoors survival, water is by far the most important thing for you to be aware of.

While a human being can survive for weeks without food, it only takes three days without water to find yourself in an extremely dangerous situation. Many water filtration systems take a lot of effort, or cost obscene amounts of money, but gravity water filtration systems have managed to bridge the gap between price and usability for campers everywhere.

Gravity water filtration systems are not only for campers and outdoorsmen. While the cities are flooded with people, many of us still live on the outskirts of society on farms, ranches, and other out of the way locations.

If your water is not satisfactory to your needs, a gravity water filtration system can provide your home with massive amounts of fresh water daily.

No matter the situation, if you are in need of a water filtration systems, gravity is the way to go! The only problem with this is that there are hundreds of these devices on the market, and figuring out the best product for you can be a real headache.

Gravity Water Filter in action

That is why we will go over the top five gravity water filtration systems you can purchase on the market today. But before we get into the product let’s go over the things you need to know about gravity water filters.

How Do They Work?

Water filtration systems work in many different ways, but there are five methods of water filtration that are most commonly used, distillation, reverse osmosis, ultraviolet, ceramic, and catalytic conversion.

  • Distillation: 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: 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: 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 convertors 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 drunken immediately otherwise the water will again become impure.
  • Reverse Osmosis: This method of filtration uses pressure to push water through a membrane that remove 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.

Most gravity water filters use the reverse osmosis method to clean water, and they are quite efficient at it. When using a gravity water filter, water is poured into the tank and then the weight of the water pushes it down through the filters.

The secondary tank is then used to store the filtered water for future use. Typical water filtration systems need to use a power source in order to pump the water through the system, but gravity water filters do not rely on power.

Instead they rely on the natural force of gravity to push the water down through the tanks and right into your canteen.

Most Important Features

When it comes to searching for the gravity water filter for you, there are a few features you should keep an eye out for.

Gravity Water Filter features

Depending on how you plan on using the water filter, some of the products in this list may not be for you.

  • Size: Gravity water filters come in many different sizes, and can range from a light weight 5 lbs. to more substantial 10-15 lbs. If you plan on leaving the water filter on your counter, than 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 figure out your typical camping setup and determine how much room you can afford in your standard gear.
  • Tank Size & Filtration Time: Typically most gravity filter tanks will be over 2 gallons, but there are smaller ones that you can find as well. If you are needing 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.
    Also take into account 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.
  • Material: 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.
  • Filter Type: Decide on what type of filter you would prefer, and what level purity you are looking for from your water filter. Make sure you read our section above on the different benefits with the filter types.

Picking out a gravity water filter can be extremely stressful, but we will give you five of the best gravity water filters on the market to give you a head start on finding the perfect system for you.

    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!

    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.

    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!

    • Jerry Mueller

      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.

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

  • Jerry Mueller

    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.
