Buying Guide 

The above is a list of the most considered gravity filter models today. If you are still having trouble choosing the best product in the list of 10 names above, you can refer to the notes below:

Filtration efficiency

Although all are equipped with membranes to trap dirt, not all products are equal in filtration efficiency.

You should choose products with the ability to filter 0.2 microns to remove dirt, bacteria, and protozoa.

Some other products can filter up to 0.1 microns, removing specific viruses and parasites, such as Outback Emergency Water Filter System or Joypur 8L.

Filter speed

You certainly won’t want to wait too long to have clean water to quench your thirst. Therefore, do not forget to pay attention to the filtering speed before deciding to buy.

Some of the most advanced filters available today allow you to produce up to 2 liters of water per minute. This speed is quite ideal for providing enough water for a group of people without spending too much time.

Easy to use

If you want to use the filter on camping trips or long journeys, you will need to install the product quickly. Because in poor conditions, you may not be able to find the necessary tools to install a water filtration system.

To avoid the above situation, you should prioritize compact products and do not take much time to set up.

Filter life

Replacing filters can cost more than you think. Better yet, you should prioritize products with a long lifespan in the first place.

Currently, quite a few devices require replacing the filter after treating 25 gallons of water. However, you also have more durable options as filters can process up to thousands of gallons before needing a replacement.


How much does a gravity filter cost?

The answer depends on the brand, capacity, and many other related factors.

Currently, the price of most gravity filter models is in the range of $200 – $500.

However, that does not mean that products with prices lower than the above range are not worth considering. Because as you can see in the list above, you have quite a few affordable options, but the quality does not let you down.

Similarly, it would help if you were not mistaken that every expensive product is a great choice and suits you best.

Are there any disadvantages of using a gravity water filter?

One of the common downsides of comb water filters is that the amount of water you can filter at a time is quite limited.

What kind of maintenance do you have to do on a gravity water filtration system?

Cleaning is something you should do regularly to maintain performance and prolong the life of your product.

The steps for cleaning are also not too complicated. You need to clean the filter elements with plain water. You can also use a little soap and water to enhance the cleaning effect.
