What is Stefani?

Origin and history

Ceramica Stefani S.A., was founded in 1947 by the Stefani brothers, it is a Brazilian company located in Jaboticabal, State of São Paulo. At the time, it started its activities with a manual production process of ceramic filters. 

To this day, part of the production remains still handmade, combining the most modern production technologies for ceramic items, which guarantees high-quality products that are highly rated in both national and international markets.

Detailed comparison: Stéfani vs Berkey

💰 Price: Stéfani wins by a large margin

Stéfani: €60-250 | Berkey: €350-500

Stéfani costs €300 to €400 less at purchase. Over 5 years of use, the gap widens further with filter replacement costs.

Total cost calculation over 5 years:

• Berkey: €400 (fountain) + €600 (filters) = €1000

Stéfani Advantage: €500 savings over 5 years.

✅ French certification: Stéfani wins

Stéfani: Certified in France | Berkey: Not certified

Stéfani is certified according to French filtration standards and on the exact amount of water filtered that we recommend. Berkey relies on unvalidated internal tests and offers a filtered water quantity that has not been tested. (Claims 6000L to 20,000L of filtered water while tests were done on only 300L)

This means that the effectiveness of Stéfani has been verified by independent laboratories, which is not the case for Berkey.

Stéfani Advantage: More safety and transparency.

📦 Availability in France: Stéfani wins

Stéfani: Available immediately | Berkey: Long delays

Stéfani is available in France, with fast delivery. Berkey must be imported from the USA, which leads to delays of 2-4 weeks and additional costs from French resellers. 

Stéfani Advantage: No waiting, no customs fees.

🔄 Filter lifespan: Berkey wins (but with caveats)

Stéfani: 600L certified | Berkey: 6000L claimed (not certified)

Berkey claims a lifespan of 6000 liters per filter, which is 10 times more than Stéfani. However, this lifespan is not certified and is based on internal tests.

In practice, users report that Berkey filters often last less time than expected, especially with heavily contaminated water.

Berkey Advantage: Theoretically more durable, but needs to be verified in practice.

🧹 Maintenance: Stéfani wins

Stéfani: Low | Berkey: Medium

Stéfani requires little maintenance. Berkey requires regular filter cleaning and has a risk of mold if not properly maintained.

Stéfani Advantage: Simpler in daily use.

🌍 Ecology: Depends on the model

Stéfani terracotta: Excellent | Berkey: Good

If you choose Stéfani in terracotta made in France, it is a 100% ecological solution. Berkey in stainless steel is less ecological due to import from the USA.

Stéfani Advantage : Especially for the terracotta version.
