The Chanson VS-70 is a nice looking model and having the under
counter model is a plus. This unit is from China/Taiwan where
the quality of their titanium plates is always a big question. The
ionizer has only a single filter and lower power to its solid plates.
They have an additional pre-filter package for about $200 which
is a positive add-on. With all the negatives, I would suggest you
buy on of the other under counter units made in Korea that
has the WQA Certification (lead-free) and has dual internal filters
and it will cost about the same.
