I was planning to order a "Big Berkey" model. They're been out of stock for a few months but available again. Usually you get a choice of a few freebees to go with it.
Now the choices include a free upgrade to a "Royal Berkey" or the two PF-2 filters. Are these two filters for "Fluoride, Arsenic V and pre-oxidized Arsenic III and Other residual heavy metal ions" desirable or should I take the upgrade.
