Watering and fertilising? Use the force of gravity and into contact with a gravity fed water filter. Try the filter of claim 1 wherein the fluid is water and at least the treatment of water, waste water, sewage , or sludge, raw , untreated water from remote lakes and streams and water from such sources! Your water reuse as filtered water in a gravity filter. The filter cartridge for water filters contaminants and chlorine taste components from the water. Contaminants must be removed from the water before it is purified water. Filter water through the filter cartridge for water must pass through porous particulate filter and flow through the vessel's interior as gravity pulls the untreated water to become drinking water. See gravity filters like Doulton ® Gravity Fed Water Filters or the Kent Gold 20 gravity based water purifier. Filtrafast is a high-rate downflow gravity or pressure filter that also filters well.
A gravity water filter is one of the few commonly used water purification techniques today, just like distillation where you boil your water to kill bacteria. Some units do offer the same benefits you can get from distillation.

Gravity Water Filters: Pros and Cons
Now, why would anyone want a gravity feed water filter? What should you be consider about this type of water filtration for your needs?
Let's take a look at the PROS & CONS of gravity water filters:
Gravity Water Filter ~BEST~ Gravity Filters (2019)
What is the best gravity fed water filter brand against toxic heavy metal compounds and pathogenic bacteria: Berkey, Katadyn, MSR or Doulton?
Berkey gravity water filter
The Berkey—or Big Berkey—filter is best used when your drinking water is packed with toxic elements like lead, copper, cadmium, arsenic and even uranium—which can be reduced for up to 100%! Independent laboratory testing results of popular gravity water filters have also suggested that the Berkey filter is the most reliable gravity filtration unit on the market, when removing toxic agents in your water is concerned.
The only flaw it has though is that, for some people, these types of filters are not within most budgets. Other than that, this is one heck of a filtration unit.
Doulton gravity water filter
This Doulton gravity water filter unit is a little more affordable for most budgets and was actually reported to provide much better-tasting water! It can produce two (2) gallons of water and stainless steel components are manufactured in the UK.
On the downside, the things that are keeping Doulton's filter from being one of the best gravity water filter products in the market today is most probably the small faucet. Several customers have reported it being a bit impractical and cheaply made, in comparison to the rest of the product. Hopefully, this will be improved in future models.
At the end of the day this is still a great offering from Doulton, and as for the quality of the water, their test results from suggest that this unit shows great potential against pathogenic bacteria like E. Coli bacteria and Cryptosporidium Cysts and the like.
Katadyn gravity filter
While Doulton and Berkey filters are ideal for indoor use because of its bulky containers, the Katadyn gravity water filter on the other hand is great for the outdoors. Just like Doulton, this one can also filter certain type of bacteria. The design on the other hand is much different compared to the other two as it has two bags instead of two steel containers.
The Katadyn filter can deliver 16 oz. per minute of filtered water and can hold up to 2.6 gallons of water in its bag. By far, this is the most affordable one of them all. Click through to see the latest price.
MSR gravity water filter
This is another on-the-go water filter unit. The filtration process of MSR water filter is pretty much identical to Katadyn. The benefits are almost the same as the Katadyn unit when it comes to eliminating bacteria and VOCs. They are certainly comparable to each other in the aspects of design and effectiveness, as well as affordability.
One of the main differences between them is the how fast they filter the water. The Katadyn can manage to filter 16 oz. of water while the MSR, is reported to be capable of reaching a whopping 1.75 liters per minute! It’s really surprising that a small filter like this can do so much in just a matter of minutes.
OUR TOP PICKS:
Which is the Best Gravity Water Filter?
So in conclusion and for the sake of gravity water filter comparison, when indoors, it’s best to use the Berkey water filter (that is if you have the extra budget) and for outdoors, MSR gravity filter is the ideal candidate since it can filter water faster than Katadyn and the price is more enticing.
To summarize, the best gravity water filters are Berkey and MSR.

How do gravity water filter systems work?
With this kind of system, you have a free standing unit where you put the water inside and let gravity do its work. But in a more detailed and specific explanation, the unit has two containers. As explained on freshwater, the upper container is where you put the water while the bottom part is where the filtration magic begins.
Inside the microporous ceramic cartridges, you will find activated charcoal bits also known as Granular Activated Carbon (GAC)—which is a major must-have when it comes to filtering your drinking water.
This combination for a gravity water filter unit, as stated on that source, is very effective against various types of contaminants like pathogenic bacteria and parasites that may cause some nasty diseases like cholera, dysentery and typhoid.
This process can also filter your water from chemicals like fluoride, chlorine and the like. Heavy metals like lead, copper and mercury are also included in the list of things this baby can protect you from, as what carehealth has pointed out.
How was this gravity filter water treatment brought to light?
The very first gravity filters for water were made way back in 1835 London, England. As cited on consciouswater, “Queen Victoria requested John Doulton (of later to become Royal Doulton), to produce a water filter with his ceramic making capabilities. Using various earth and clay materials, he created the first gravity water filter stoneware, Doulton water filters.”
Carbon Water Filter, London, England, 1890 – 1915
Interesting isn’t it? Who would’ve thought that gravity fed water filter was first made back in the 1800s!
Different types of gravity water filter systems
Just like any filtration method, a gravity fed water filter also has many variations, and each one of them has a purpose to fill.
- Ceramic gravity water filter: A ceramic water filter is ideal for people who are allergic or sensitive to chemicals. For the how this type of water filter works, it is pretty much the same as the steel water filter unit. You put the water inside the top ceramic container and that’s it.
- Stainless steel gravity water filter: Most of the stainless steel filters in the market today are big in size or at least bigger than the average ceramic unit. If you are on the go or renting a house, this one is ideal for you. The difference between the two is, ceramic gravity filters are fragile and can break if you accidentally drop them on the floor. Since this unit is lighter and doesn’t need complex installation or hardware, more mobile families or people can take this along wherever they move.
- Portable drip gravity water filters: Gravity water filter backpacking or just simply, a gravity bag water filter is the real on-the-go filter unit. Like the MSR and Katadyn, this type is beneficial for people who like to travel or go camping. You don’t want to bring a huge stainless steel gravity water filter when going camping--not very convenient if you ask me.
Do-it-Yourself or DIY Water Filter
Having a water filtration unit in your house is a great investment for your future health especially in the case of terrible emergencies like water contamination disasters or hurricanes. That’s why here; I will teach you how to make your very own water filter system.
The things you will need for a free standing unit are, as suggested on MomWithAPrep.com:
The total cost of this project could possible be well under a hundred dollars if you already have some of these items. Of course, you can check each link above for more updated prices.
How to make a free-standing water filter:
Drill a hole on your lower container (where you will put your faucet in). Make sure that the hole you drilled is an exact fit for the spigot/faucet. Once you’re done, slide it in and put the knot to make sure it is sealed in place.
Measure your dome water filter inside your second food grade bucket (or the upper container). Place the water filter dome inside and use a marker or just memorize where you put it. Then once you are contented with the placement, it is now time to drill the bottom surface of your upper container. After that, do not place your dome filter just yet.
Pick up the lid of your lower container and put the upper container on top of it. You can clearly see the hole of the second container on your lid because of the plastic. Drill a hole that will match the other one.
Put them all together by sliding the dome filter inside your upper container and the lid of the lower container and locking them in place with the plastic knot that was provided. Do that for the other one and you’re done! You now have your very own gravity fed water filter unit. Rinse and wash the filter properly after the process.
DIY Gravity Bag Water Filter:
Things You'll Need
Total cost would probably be around $80, give or take, so it maybe impractical to go the DIY route since there are commercial options available that are relatively close to this price point. Here are the steps, regardless:
How to make a gravity bag water filter:
Cut the ring off the top part of the Katadyn Hiker Pro Water Microfilter. Fair warning; be careful on this one.
Cut the upper part of the Nalgene 32 oz. wide mouth bottle and the lid.
Cut a hole on your dry sack bag, just the exact size of the tip of the Katadyn Hiker Pro.
Now for the assembly part, take the Katadyn Microfilter and push the upper part of your Nalgene bottle. As said on that video, this is an exact fit and you shouldn’t worry about any leakage of some sort.
Now once you have put them together, place it inside the bag and make sure the tip of the filter is inside the hole of your dry sack bag. Take the lid of your Nalgene 32 oz. wide mouth bottle and screw them together. You don’t want to screw them together too hard because it might tear the dry sack bag.
Take the hose from the hiker pro filter and press it on the tip of your filter and that’s it! Just use a hose clamp to lock the flow and you are all set!
How effective is this compared to the other leading products?
The effectiveness of your DIY water filter will depend on the quality of materials you will be using. For a filter system, we recommend the Berkey Ceramic filter—since it is a trusted brand, though it is not a dome filter, and more like a candle-shaped one. It should work the same, as the only difference is the design.
Conclusion: Gravity Water Filters Rule!
So there you have it!
All the things you need to know about gravity water filter from how it works, its history, different types and how you can build one (free standing unit and gravity water filter backpacking). We hope you had fun learning and reading about gravity water filters!
