Relatively Compact and effective
The water tastes well after a few gallons of run off. The price is reasonable given the NSF certificate.

I ordered two filters and was surprised to receive the entire filtration system. This wasn't Clea. Needless to say, those are good filters. water tastes good. The flow was slow today.

Leaking
Bought replacement filters for existing 2year old unit. Leaked... tried replacing o rings-did not work. I read a strange review where someone had the same problem to place a penny in the container because filters are now as long. Did not try because I already bought a replacement system.
