This filter I can not recommend definitely. As coffee and tea lovers I bought my Brita Maxtra filter and can make a comparison of the Aqua Optima Evolve 90-day filter to the original filter of Brita. Of course, not with professional equipment - it also is in my opinion no reason when the kettle begins to form lime already at the dawn of the second week. About the coffee also swims already the limescale. The water tastes definitely not as soft as the original filtered Brita filter. That's what I noticed after the first Beverage by direct application.
How should these filters provide the specified 90 days anyway? That remains a mystery to me. For this reason, I will definitely return the order.
For further questions I am happy to help and would be happy about an assessment, if this review has helped you with your purchase decision.
