Review: Excellent product with a subjective caveat - I installed four of these filters in my Big Berkey 2.25 gallon unit and they work well. I have not tested tested the claims made of removal of contaminants but, I was pleased to see they were NSF certified. The taste of the water (subjective) is clean but flat. According to several forum posts: "taste and mouthfeel in water come largely from total dissolved solids (TDS), especially minerals like calcium, magnesium, sodium, and bicarbonate. When TDS is very low, and both chlorine and minerals are reduced, the remaining water can seem extremely clean but also characterless or flat." In short: I may reach out to the company and explain my situation and see what they recommend. Most say to add food‑grade mineral drops or a pinch of a balanced mineral salt to make it more palatable. Despite the flat taste, I am happy with the product and functionality and would highly recommended these as an alternative to the Berkey charcoal filters. Update: The British Berkfeld website FAQ states the following "Your water's mineral content will depend on where you live." It's likely that my local water provider is the root cause of my situation. We have frequent boil water advisories so I am not surprised to learn this.
Review: Perfect fit for Big Berkey system, fast & efficient - My husband & I have had the Big Berkey system for over a decade. We've always used the black charcoal filters and while we had no issues for years, lately, perhaps because we're now a family of 4, they kept failing. I had grown beyond tired of constantly scrubbing the filters & repriming only to have them only filter down about 25% of the way, so I was very hopeful when I stumbled upon these compatible filters. The first 2 passes were extremely slow, as expected, but after that, they filter at lightning speed compared to my old Berkey filters. I can't confirm the filtering quality specifically since I haven't had it tested, but the water tastes great and I trust the certifications behind it. I wish we'd found these years ago so we could have avoided drinking bottled water while waiting for our old filters to think about working.

### ⭐⭐⭐⭐⭐ Backed by strong certifications and history
*by M***L on September 24, 2025*

Use these as a replacement for the original carbon filters in my travel berkey, and can say that I won’t be going back to the originals after these. After the royal berkey certification controversy I decided to find new replacements. I spent far too long researching and watching/reading lab test reviews. My gut sense brought me to these. While not very popular in the US, after doing research you may find that Royal Berkefeld is the original inventor of these types of filters and holds more filter certifications than pretty much any filter maker. They are backed history, science/certifications, and a seemingly strong customer base in other countries. While I couldn’t perform any lab testing, I feel relatively confident in there filtering ability and can say that the taste is quite good when filtering Atlanta city water. When first using, expect SLOW filtering, hours. But after 3-4 days of use they became fully saturated and the flow was on par with other filters I’ve used. They also let you register them online. Very Satisfied. Good price too.
