Product review (5 stars): ProPur Video Review an Excellent filter.
We use both the ProPur and the Big Berkey and love them both. The ProPur tastes better and I think that this is because there are no filters hanging down into the water on the ProPur where filters do hang into the water below on the Berkey.  I made a video review and it is posted on YouTube. Just copy this number to the YouTube search engine or right click on it here and watch it - youtube.com/watch?v=gywNsOJJf-8
