my take in water filtration is that to reduce as much contaminants as possible. entry range is pretty much good however, having something that filters more gives a peace of mind at least. i'm not talking about price but what the filtration capabilities and getting it from proven brands too like panasonic,3m etc etc..

i've been using PJ-6RF for 5 years now, 6 months filter life is an economy approach. i'm considering removal of lead in my apartment water (because we do not know what are in the pipes)

cheers!
