Hello water enthusiasts, we’re here today to discuss an exciting match-up that’s been gathering steam in the world of gravity water filters. We’re talking about the heavyweight showdown between the Berkey and Stefani gravity water filters. These two have been vying for the top spot, and it’s time we settle the score.
To ensure a fair comparison, we’ll be evaluating them based on the following criteria: filtration effectiveness, capacity, durability, and ease of use and maintenance.
Here at the offices of The Green Directory, we have both a Royal Berkey as well as a Stefani Sao Joa, which have both been very well used for the past 2 years so we can give our unbiased opinion of both the filters.
Round 1: Filtration Effectiveness
Berkey filters are known for their powerful purification process, removing 99.999% of viruses and pathogenic bacteria. They also remove heavy metals, pharmaceuticals, and even fluoride with the optional PF-2 fluoride filter.
Stefani, on the other hand, claims to remove 99.9% of water-born microorganisms and particles. Their filters are crafted with microporous ceramic, infused with colloidal silver, preventing bacteria growth within the filter.
While both are highly effective, Berkey edges this round due to its broader spectrum of contaminants removal.
Round 2: Capacity
Berkey offers a range of sizes from the 1.5-gallon / 5.5Litre Travel Berkey to the massive 6-gallon / 22 litre Crown Berkey. This flexibility makes Berkey suitable for single-person use to large families or groups.
Stefani’s gravity water filters come in 4Litre and 6-litre sizes. While not as varied, Stefani’s options are sufficient for most households.
This round is a tie. Both offer reasonable capacities, but Berkey provides a wider range.
Round 3: Durability
Berkey’s stainless steel construction is not only sleek but also highly durable. It’s designed to last for years, making it a worthy investment.
Stefani opts for terracotta construction, providing a more natural aesthetic. However, terracotta is more prone to cracking and damage, especially during transportation or if accidentally knocked over.
We have already broken one Stefani, and have feedback from readers who have done the same. You need to be very careful when cleaning and changing filters.
Being stainless stell, the Berkey can survive a fall from the countertop and so wins this round due to its robust and durable design.
Round 4: Water Taste
You’re most likely buying a water filter to make your water taste better. We found in blind testing that there is very little difference in the taste of the water after filtering, although some tasters reported a slightly metallic taste from the Berkey.
The Stefani provides natural ceramic cooling for the water and it is noticably cooler than room temperature.
This round goes to Stefani for the additional natural cooling feature.
Round 5: Maintenance
Both systems are straightforward to use. Fill the top chamber with water, and gravity does the rest. Berkey filters need replacement after approximately 6,000 gallons, while Stefani’s ceramic filter requires replacement every 6-9 months, depending on use.
Changing or cleaning the filter on both devices is a bit of a process and requires fairly strong fingers to unscrew and screw the filters. Care needs to be taken on both models to hold the plastic base of the filter while screwing it in and not the filter itself that can come apart from the base. The Berkey filters seem to be more robust and better made for long term use and regular cleaning.
Both filters develop a layer of slime on the outside that dramatically reduces flow. In warmer temperatures the filters need to be cleaned more frequently to maintain flow – this comprises wiping down with a soft sponge in clean water.
The Stefani only can take a single filter, which after a few months of use starts to drip through at a very low rate and is unlikely to be able to provide enough water for a family or small team by itself, whereas the Berkey Royal can take up to 4 filters (we have 2 in at a time) providing much faster filtering times and less frequent cleaning.
Berkey wins this round since it filters faster and is easier to clean being make of stainless steel.
Round 6: Price
Both of these water filters are in the premium end of the gravity filter range.
On Amazon the Stefani goes for $150 with a single filter included. Replacement filters sell for $30 each
And the Royal Berkey for $426 with 2 included filters. Replacement filters sell for $170 for a pack of 2.
The Berkey is the much more expensive option, however it filters a much larger volume of water for the same price and requires less frequent filling.
Conclusion
The competition has been fierce, but the Berkey water filter edges this showdown. Its superior filtration capabilities, larger capacity range, and stainless steel durability make it the winner. However, Stefani’s gravity water filter is still a strong contender, particularly for those who prefer a more natural aesthetic and the bonus cooling feature.
Remember, the best filter for you depends on your specific needs and preferences. Both Berkey and Stefani offer quality solutions for clean, fresh drinking water. So, drink up, and stay healthy!
