You should definitely check it and start the painful process of getting them to send you new filters if they are defective.
There have been numerous threads on prepper and homestead sites about this problem. It’s real and Berkey has gone from the best countertop filter to the worst IMO not just because of this problem but their customer service too.
If someone pays hundreds of dollars for a product it should work as advertised. The old Berkey’s were great but their efforts to save money and ramp up production have destroyed a great reputation.
Buyer beware.
Regardless of which filter you may be using, after running the water through the filter, it should either be boiled or treated with SSKI.
Just common sense.
