PROS: 1. The water tastes great. 2. The stem threads into the base, but is double gasketed with O rings. This means that you don''t have to tighten it down, and you can rotate it to any position and it won''t leak from the base of the stem, as long as you don''t unscrew it all the way. It also means you can point the handle in any direction you like, not just the one shown in the picture. 3. The faucet handle can be held down or flipped up and released to pour water. You don''t have to hold it if you flip it up. 4. Installation was as easy as plumbing can be. If the supplied T fitting fits what you have under your sink, then you will be fine. If it does not fit, and you do not know what to do to make it fit, CALL A PLUMBER. This is what they do, and it won''t cost you much, because it''s an easy job.

CONS: The water keeps running after you shut it off. This is not a malfunction, it is a design flaw. The instructions even make reference to it. Considering the cost of this item, I feel this is a major drawback. I am not impressed. This bothers me every time I use it.

NEUTRAL: 1. Water does not come out cold. It sits in the filters at room temperature, so you''d have to run it for a LONG time before it would be the same temp as the water coming out of your cold water tap. It must be refrigerated if you want it cold. This is fine. Just fill a pitcher, not a glass. 2. Water runs very slow. Filling a pitcher, or a coffee pot takes a while. 3. The reason the filter faucet runs on is because the valve in the handle turns water on and off to the inlet of the filter, not to the faucet itself. I can only assume this is done so that the filtration system itself does not need to handle any real pressure. This would make it less expensive to manufacture, but like i indicated above it also means that the water runs for 5-10 seconds after you shut it off, as water pressure bleeds off, and residual water siphons out.

HOMEOWNER TIP: If you do call a plumber to install your water filter, whether it''s this one or not, ask him to replace your shut off valves with 1/4 turn "ball valves" if they are not ball valves already. He''ll explain why it''s a good idea, and why this is a good time to do it. He''ll also think you''re an educated homeowner, which is in your favor.

The kit came with everything I needed to replace the sprayer house sink attachment and add this water filter. It took a couple of hours to clean out under the sink, and complete the install, but it was not difficult. The water is tasteless now, and makes much better ice cubes.

I bought the Aquasana to eliminate contaminants and strange odors from our water and it''s done a fantastic job. It was relatively easy to install, took about 20 minutes. The complaints about it dripping after being shut off are valid, however, the manufacturer tells you up front that the unit will drip for about 5-10 seconds. It''s really not a big deal, we just shut it off a bit earlier, the quality of the water it puts out makes it all worth while. The water is completely flavor/odorless, exactly what I needed! Our municipal water contains a significant amount of bleach and other contaminants that can''t be removed using pitcher filters, but that the Aquasana IS rated to remove. If you want clean and healthy water, there is no substitute.

Want Aquasana AQ-4500 Complete Under Counter Water Filter System Discount?

We have just replaced our Aquasana AQ 4050 system and wished that we had done so years ago. We replaced it with a Watts Filter-Pure UF3 system which produces much better water for a better price. The Aquasana unit produced poor tasting water, came with a cheap plastic faucet that eventually stopped working, had filters that were difficult to change, had poor customer service and was very expensive to buy new filters for. Also, the pressure in the unit is reduced such that the flow is way too slow. Aquasana will sign you up with a discount if you sign on to a program where they automatically send you replacement filters every six months they are still way too expensive even after that! I realize now that we were drinking sub-standard water from the Aquasana unit for over a year, despite all the so called specifications and website comparisons that they put out. Sorry to post a negative review but I enjoyed throwing the Aquasana unit into the trash!

First of all the water quality is very good, the filter housing is very poor. I have changed out three housings due to leakage issues. The o-rings provided are undersized for the filter housing lids and will easily move out of position when reinstalling the covers even using o-ring lubricant. The covers are light weight poor quality plastic and threaded, the thumb tabs have broken off several of the covers. An Aquasana representative reluctantly acknowledged they have a problem with the filter housings. He stated he would replace the housing free of charge if I would enroll in an automatic filter program, I refused his offer and changed to another brand of water filter at my expense. The filters themselves are somewhat pricey it appears this is where Aquasana makes their money and I would have been willing to accept that if it were not for the poor quality filter housing. I work with industrial liquid filtration systems of all kinds and have the mechanical ability to change the media in any kind of filtration system without incident until I started dealing with the Aquasana filter housing. Save yourself time and aggravation forget the Aquasana brand and look at other products on the market.
