Great filter but poorly made:
The Aquasana product line is well designed but too cheaply made to survive the effects of repeated filter changes. The plastic parts bind up, strip and break unless you use the greatest caution when replacing filters. The housing for the filters split and had to be replaced to the tune of $40.00 as a result of excessive water pressure. I can assure you that my hundred year old house could never produce excessive water pressure. The hose fitting snapped off when I was attempting to unscrew the openning for the one of the filters. It is made of 1/8 inch pvc plastic. I was able to epoxy a brass replacement nipple for the hose and it is working well now. In short, Aquasana should realize that most consumers are prepared to spend a little more in the beginnign to avoid having to pay later for poorly made parts. If this unit fails again I will find something to replace it.

Great water filter, will use for years!:
I have the Aquasana AQ-4000 under my sink and am really happy with the quality of filtered water it produces and the ease of use. I get my filters sent to me automatically every six months which makes it easy to remember and they even give you a lifetime warranty on the system! Not many companies are willing to warranty their products for life.

Good Water, Poor Build quality and design:
The filtered water was very good. However, the plastic parts are not durable and the over all design is poor. Changing the filter and replacing the O rings is shear aggravation. Water will seep from the filter lids, since the O rings want to bind, no matter how much lubricant is applied. The plastic threaded filter lids are not very sturdy and will strip their threads without much effort. Once the filter lids are on, they are a struggle to remove. The frail connection between the Filter Housings is much to easy to break. Avoid this unit. Much to fussy to maintain and poor design.

Don't Waste Your Money!!:
The Aquasana water filtration system is poorly designed and made. Don't waste your money either buying the product, or investing in additional costly replacement water filters. Take the time to find a NSF certified water filter (which this one is not) and you'll end up with a better quality product. Good luck!

Cautiously, Nervously Optimistic:
Our plastic fittings burst off and flooded our kitchen last summer. I had to replace the plastic fitting with a brass one and have been so nervous about replacing the filters and having another flood, our water is down to a barely noticeable dribble. Nonetheless, I will buy the replacement filters and hope for the best. The unit looks nice and the water is excellent.
