1. Gravity Water Filters

The comparison of these two renowned brands of tap water filtration is incomplete without introducing gravity water filtration systems. Both of them work on the same principle. 

Gravity water filters are those filters that are aided by gravity in their work. The principle is simple yet effective. The filter is made of two chambers where one is stacked upon the other, and between them is fitted with a filter. It uses the gravity pull, and the water is pulled down from the top chamber to the lower chamber, passing from a filter. 

The gravity filters comprise small holes where the water passes through, blocking the sediments and pollutants, making it clean and suitable water to drink.

There are so many best gravity water filters; Berkey and Propur filters are among them. Here is a detailed comparison of their features and their perks. 

2. What Contaminants Do They Remove?

When it comes to filtration demonstration, we need to understand the filter’s effectiveness in removing contaminants from water. What are those contaminants that they remove? So, here we go:

With a wide range of contaminants and pollutants found in natural water, both Berkey and Propur water filters come in handy in their removal. 


Big Berkey removes viruses up to a great extent. It is also effective in the removal of pathogenic bacteria and surrogates about 100%. These pathogenic bacteria include Raoultella Terrigena, Bacillus Atrophaeus, Salmonella Enterica, etc. 

Berkey gravity filters are effective against the removal of inorganic minerals and heavy metals to a greater extent. These inorganic minerals are chloramines and free chlorine. 

Berkey filters will not disappoint you in the removal of pesticides and volatile organic compounds such as tetrachloroethane, alkanes, alkenes, alkynes, benzenes, chloroform, dicamba, disulfoton, halo acidic acid (HAA5), and a long list of organic compounds that are not suitable for your body. 

Apart from that, you will have a reduced quantity or number of other harmful substances in your drinking water. They are Arsenic, E. Coli bacteria, Halogens, mineral spirits, rust, sediments, etc. 


Propur water filter is also quite effective in removing various types of contaminants and dirt from your drinking water, proving to be a great water filter out there in the market. Propur filter elements are more effective in fluoride removal.

Propur removes dirt and heavy metals from your drinking water, ranging from inorganic minerals, heavy metal ions, organic compounds to pesticides, viruses, and bacteria. It is equally effective and powerful when it comes to the removal of these pollutants.

3. Design & Models

There are so many models and designs of these two water filters. They are:


  • Big Berkey Filter with a 2.25-gallon system
  • The Travel Berkey with a 1.5-gallon system
  • The Royal Berkey with a 3.25-gallon system
  • The Imperial Berkey with 4.5 gallons of water filtration
  • The Crown Berkey with 6 gallons
  • The Berkey Light with a 2.75-gallon system


Among the gravity filters, the Propur also has so many models, but out of them, the effective models are listed below:

  • The Propur Big with 2.75-gallon water filtration system
  • The Propur Traveler with 1.75 gallons of water filtration
  • The Propur Scout 2 with half gallon water

4. The Flow Rate or Capacity 

The Berkey filters have the Capacity to filter out an astounding number of 200 contaminants from water at an incredible pace. It filters out 3.5 gallons of water in an hour. 

The speed depends on the water level in the filter, and it means that the lower water level in the filter reduces the flow rate. To maintain it, you need to regulate the water level and keep it to the top.  

Both Propur and Berkey have the exact match in flow rate. As compared to Berkey, there is a slight delay in the filtration process of Propur, and its flow rate is a bit less than Berkey. It filters 3 gallons of water to make it clean in around 6 to 7 hours. 

Here, we can conclude that the Big Berkey water filter is the winner for the filtration flow rate. 

5. Certification 

These water filters are renowned brands in this aspect. Thus, they hold certifications that enhance their credibility. 

The Berkey water filter is NSF certified for standard 53. It is the certification that ensures that the product meets all the standards set to ensure public health. It also certifies that the POU system removes the harmful pollutants in water, making it suitable for drinking. 

Like the Berkey water filter, Propur is not NSF verified for standard 53. However, it is tested independently and has been proven effective in removing harmful contaminants from the water. But it is not considered credible and more authentic for water treatment. 

6. Filter Lifespan and Annual Maintenance Cost

The lifespan of a filter matters a lot because it tells you of its durability. No one wants to spend an enormous amount of money more often. Therefore, you may be mindful of finding out which one is more durable and costs fewer bucks on its maintenance. 


Buying a pack of 2 black Berkey Elements that you can fit to make a countertop gravity water filter system, you can relax your mind by thinking that it can last for filtering water up to approximately 6000 gallons before you can consider its replacement. 

Here, you can’t figure out the exact time frame for the replacement of filter elements because it solely depends on your water filter usage, and it means how much water you filter every day. 

We may say that the more you use it to filter water, the quicker you will need to replace it, and it will cost you money for its maintenance. 

If you consider replacing the element of your Berkey water filters, it may cost you a huge buck of about $120 for a pack of 2 elements. On average, it lasts up to 3 years or 36 months. 


Propur ProOne water filter is different in terms of maintenance and lifespan. You will need to buy them individually, and they come in different sizes with variable lifespans. 

The Propur filter system has three different sizes ranging from most petite (5 inches), medium (7 inches), and large filters (9 inches). The smallest filter costs around $70, the medium $75, and the 9-inch large filter comes with a price of nearly about $80. 

You can understand the simple fact that the larger the filter size is, the longer it will last. The average lifespan of these filters varies from small to large. The 7 inch lasts for six months with daily usage, and the 7 inch takes ten months to be replaced, while the larger 9-inch filter lasts up to a year. 

7. Warranty 

The warranty of a product determines its durability and quality, and it is the warranty that turns someone into a buyer of the product. A warranty ensures that your money will be worth the value. 

Both of them are best in terms of product warranty. Berkey filter offers you a warranty of 2 years for their filter and one year for their filter system, while Propur covers its filter for one year and the system for two years. 

This period is a reasonable time to consider because a filter is best if it lasts for a year. You must be mindful that you should not use soft water in your filter because it reduces the durability of your gravity water filter and shortens its lifespan.
