Understanding Water Contamination
Contaminants such as PFAS, pesticide residues, chlorine, chloramine, pharmaceuticals, hormones, bacteria, viruses, heavy metals, nitrates, fluoride, microplastics and endocrine disruptors can be found in water. Filtration then becomes a valuable tool to reduce these risks.
Gravity filtration systems
What is a gravity filtration system?
Gravity filtration systems, such as Monderma and Berkey, harness gravitational force to move water through filters. These devices are known for their robustness and their ability to remove a wide range of impurities.
Analysis of Berkey filters
Variants of Berkey filters
Berkey offers several models:
- Black Berkey : an activated carbon filter, known for its capacity to reduce organic contaminants and heavy metals.
- Berkey Light, Travel Berkey, Big Berkey, Royal Berkey, Imperial Berkey and Crown Berkey : each model offers varied filtration capacities, thus adapting to different household sizes.
Independent testing and certifications such as NSF 42, NSF 53 and NSF P231 have validated the effectiveness of Berkey filters. However, it is important to distinguish between "NSF certified" and "tested to NSF standards."
More information on Black Berkey filters is available here.

Discover Monderma filters
The characteristics of Monderma filters
Monderma filters incorporate technologies like ceramic and activated carbon filters for complete filtration. The model Monderma Big 8.5L is particularly well suited for families, with a capacity of 8.5 liters and the promise of effectively removing heavy metals and PFAS.

Maintenance and cleaning
Whether for Monderma or Berkey, filter maintenance is fundamental to ensure optimal lifespan and efficiency. Check out our article on cleaning and replacing Black Berkey filters here.
FAQs
What is the NSF, and how is it different from independent testing?
The NSF is an organization that certifies products that meet certain health and safety standards. Products may be "NSF certified" or simply "tested to NSF standards" without being certified. Independent testing, on the other hand, is carried out by laboratories like Envirotek, Eurofins, SGS, or WQA, which may include but is not limited to certain NSF standards.
Conclusion
When choosing a water filter, it is essential to understand your filtration needs, the nature of your water, and the technical performance of the products. Equipment like Monderma and Berkey offer reliable solutions for purifying your water from unwanted contaminants. For more information, visit our website.
Frequently Asked Questions
What heavy metals can Monderma and Berkey filters remove?
Monderma and Berkey filters are designed to reduce several heavy metals found in water, such as lead, mercury and arsenic. Each of the filters uses specific technology to capture these contaminants and ensure safer drinking water.
What are PFAS and why are they of concern?
PFAS, or perfluoroalkyl substances, are synthetic chemicals used in various products, such as non-stick coatings and firefighting foams. They are of concern due to their persistence in the environment and potentially toxic to human health, being associated with various health problems.
How do the filtration performances between Monderma and Berkey compare in terms of PFAS?
Both filters, Monderma and Berkey, show effectiveness in reducing PFAS, but removal levels may vary. Independent testing has shown that Berkey filters often perform better, removing up to 99% of PFAS, while Monderma filters are also effective, but may have slightly lower results.
How long do Monderma and Berkey filters last?
The lifespan of the filters depends on the use and the quality of the water filtered. Generally, Monderma filters should be replaced every 6 months, while Berkey filters can last up to 2 years, depending on frequency of use and contaminant load.
Is it necessary to test the water before using a filter?
It is recommended to test the water to determine the contaminants present. This allows you to choose the filter best suited to your needs. Testing can reveal the presence of heavy metals, PFAS and other pollutants, helping you make an informed decision.
Are Monderma and Berkey filters easy to install?
Yes, both filtration systems are designed for quick and easy installation. Monderma filters attach easily to the faucet, while the Berkey system requires light assembly but includes clear instructions to help users.
What is the filtered water storage capacity for Monderma and Berkey systems?
The Berkey system is designed to store a larger quantity of water, typically between 8 to 12 liters, depending on the model. On the other hand, the storage capacity of Monderma filters is generally more limited and focuses on quantities suitable for daily use.
Are the filters environmentally friendly?
Both filtration options strive to be environmentally friendly. However, Berkey filters produce less plastic waste due to their longevity and ability to filter large quantities of water. Monderma also offers durable filtration lines, but their frequency of replacement may result in more waste in the long term.
Do the filters also remove bacteria and viruses from the water?
Yes, Berkey filters are designed to remove not only heavy metals and PFAS, but also a wide range of bacteria and viruses. Monderma filters, although effective for certain contaminants, may not guarantee the same significant reduction in microorganisms. It is therefore important to carefully check the specifications of each system.
