    Good Points: Great water filter.


    Bad Points: None for me.


    General comments: Thanks to the Aquasana AQ-4000 I do not have to worry about drinking contaminated H2O. It was easy to install and the water tastes yummy. To all the women, drink out of non-porous bottles as plastic may affect your hormones thus increase PMS symptoms! It did wonders for me.

    Initial impression of the Aquasana filter was that it was relatively simple to maintain. Once I had changed the filters a few times, I simply hated the device.

    We are on our second Aquasana AQ-4000 housing unit. We have gone through three or four faucet adapters. We change the filters frequently.

    When the filters go, the unit takes hours to fill up a jug of water instead of minutes.

    The support is good, but the filter is just not made to last. They are cheap plastic components. You have to be careful that you do not damage the plastic nut grooves when using a socket wrench to change the cartridges.
