Aquasana AQ-4000

I had bought this system and found it to work well. TILL the day the housing for the filter came apart. The result: a soaking wet kitchen floor and customer services tell me that the another set of filter will cost $ 48.00. Why is it that a manufacturing problem on their end would cost me time and money. For that reason I'm choosing another product. Good Luck

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. The O-Ring seal method chosen is too fussy; no matter how well lubricated, they will bunch up preventing a seal. Getting the filter covers tight enough to stop seepage is also very difficult. Once they are tight , it took a pair of Channel Locks to get them off. As far as the materials go, the covers plastic threads are very easy to shear off. The brittle plastic fittings on the bottom of the filter (where the water passes from one side to the other) breaks too easily even with careful handling. Overall,mine was a piece of junk. Do not buy it for any amount.

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.

AQ-4000 Aquasana Filter Drinking Water System is a complete filtration system with twin filter cartridges, chrome faucet diverter and easy to follow instructions. Installs in seconds, switch from filtered to unfiltered with the touch of a button.
