AQUA CREST PF-2 Water Filter, Compatible with PF-2 Fluoride/Arsenic Water Filter (Pack of 2)

It was easy to replace previous filter and is working fine so far.

Easy to install

On the Berkey filter the directions say same as this filter, to only turn 7 or so times so that the inner seal is not punctured. But if you take a q-tip and gently put it in the UP end, the Berkey's filter seal & content are at the top and the q-tip only goes in a short distance. This filter's turned the opposite direction and the q-tip goes in the botton the same distance as the top of the Berkey filter. If putting a q-tip in the UP end of this filter it goes a much longer distance into the canister... similar to the bottom opening of the Berkey. I don't know that it really makes any difference in it's filtering capabilities but you don't need to be so concerned about not tightening the the filter into place with only the exact turns.

I bought these a year ago when there was a water safety crisis in my city but when I went to install them, discovered that they do not thread onto the black filters that I have. I suppose it should work if you buy black filters from the same manufacturer. My bad, now I have extra fluoride filters I can’t use.

Product seems ok. Water has a bit of a taste different to the authentic product. But this could be simple to the changes that seem to be with the actual water.
