This review is from: Aquasana Countertop Water Filter System AQ-4000 Good filter, reasonable price -- does what it's supposed to.......... but --- We bought the filter after doing a couple of hours of research. Essentially everything you'll read elseware about it is true. I'll just add a couple of detractors so that you get the whole picture. 1. The first thing you'll noticed when using the filter is that it takes it's own sweet time. If you think you're going to get a full size stream of water at full pressure -- think again. So, plan ahead -- factor in the fairly slow flow rate, and you'll be fine. 2. Everything functions as advertised. However, what is not mentioned is that the water diverter valve stem (the little metal button you pull on to divert the faucet water into the filter) does not always return itself to the off position when you turn off the water -- you have to push the valve stem back in to fully deactivate the filter. This may not sound like a big deal, but it can potentially destroy...

Admittedly, the water tastes great. The housing is so sensitive that you can only run water through it at and incredibly low pressure to keep it from bursting. We do our best, but it is so inconvenient and if you have a household of a few people, somebody is sure to not care and run it through at a normal pressure, which is way too much for this filter. After the first one burst, I dumbly bought another one thinking that we could just be more careful this time. After a few months the second one just burst. It was while I was running the water this time, so I know I was running it on a very low pressure. I'm completely disappointed. Why they don't fix this problem after so many people have complained (read reviews everywhere), I don't know. If you live alone and have a lot of time and patience to fill your glass very very slowly, then...

Wiersch (Lantana, TX USA (near Dallas)) - See all my reviews       Filters are much more difficult to install than I think they should be, unit consistently breaks or has a problem every few months. The white plastic filter housing has broken twice (see photo) and I've had to replace the faucet/dispenser at least once because it constantly dripped or even poured. I am now on hold to get another part since I am a "Water 4 Life" subscriber for about $100 year - which includes two filter changes and warranty. Eventually I will probably spend the time and money to get a better unit. UPDATE 2008-11-29: After the water filter housing broke a third time, I requested that they send me another one for free which they did (no shipping charge) (I am a Water4Life customer). They seem to have redesigned this part so hopefully it will not break again.
