Best Gravity Water Filter
The best gravity water filtration solutions provide versatile gravity-fed filtering for your next trip. Gravity-powered filter treatment is typically a great way to simply use stream water for drinking when outdoors. Try best-in-class gravity filtration today.


Gravity filters use gravity to move water down from a suspended reservoir, through a water filter, and into a waiting receptacle. Unlike squeeze filters and pump filters that push water through your filter, gravity fed water filters don’t need the use of your hands and effort to produce potable drinking water.

In certain situations, the flexibility that gravity filters provide us (to do other things while gravity takes care of the water filtering) can sometimes be worth the price alone. So we set out to find the finest ones to bring with us whenever and wherever we need clean water.

If you’re looking for a great gravity filtration system, you’re definitely in the RIGHT PLACE. Read on…

What is the best gravity filter brand against toxic heavy metal compounds and pathogenic bacteria: Berkey, Katadyn, MSR or Doulton? Find out how each of these options stacks up against each other.

Option #1 Big Berkey Gravity Water Filter Bundle

Big Berkey Water Filter Stainless Steel Bundle: 2 Black Filters,...


This Big Berkey Water Filter Stainless Steel Bundle  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 filters have also suggested that the Berkey filter is the most reliable 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 option is one heck of a filtration unit.


  • Filter lasts a long time.
  • Chemicals and bacteria are removed.
  • Chambers made of stainless steel


  • Not as affordable as other options.

Option #2 Doulton W9361122 Gravity Water Filter

Doulton W9361122 Stainless Steel Gravity Filter System


This Doulton W9361122  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 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 this offer. Hopefully, this will be improved in future models. At the end of the day this choice is still a great solution from Doulton, and as for the quality of the water, their test results from suggest that this option shows great potential against pathogenic bacteria like E. Coli bacteria and Cryptosporidium Cysts and the like.


  • This water filtration system has excellent speed and flow.
  • It eliminates the sulfur odor in the water.
  • Simple installation with the instructions.


  • Total dissolved solids will not be filtered.

Option #3 Katadyn Base Camp Pro Gravity Water Filter

Katadyn Base Camp Pro Water Filter, 10-Liter, Blue (8019201)


While Doulton and Berkey filters are ideal for indoor use because of its bulky containers, the Katadyn filter  on the other hand is great for the outdoors. Just like Doulton, this offer 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. This option is more affordable for most budgets as well.


  • Perfect for large group expeditions and extended backcountry trips.
  • Works well with a shower attachment.


  • Some customers have noticed the filter rate decrease rapidly.

Option #4 MSR AutoFlow Gravity Water Filter

MSR AutoFlow Gravity Water Filter for Camping and Backpacking,...


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 choice can do so much in just a matter of minutes.


  • Large water treatment capacity for super fast potable water
  • Simple to use
  • Extremely lightweight


  • The bottle adapter seems a bit unsanitary.

Which gravity water filtration solution is truly the best?

So in conclusion and for the sake of comparison, when indoors, it’s best to use the Berkey water filter (that is if you have the extra budget) and for outdoors, MSR filter is the ideal candidate since it can filter water faster than Katadyn and the price is more enticing. To summarize, the offers we like the most are Berkey and MSR.

For Heavy Duty Use:

  • Indoors
  • Disaster aid operations
  • fixed locations
  • WINNER: Big Berkey 

For Portable Use:

  • Outdoor activities
  • Hiking and camping
  • travel and adventure
