I bought my counter top water filter about two years ago and have the Water for Life filter replacement plan. The water filter itself seems to work great. I fill up my own bottles before I leave the house and I have good, clean water all day. I ran out while at work one day and filled up my bottle from the tap. The water had so much chlorine in it I had to pour it back out. The problem with this filter system is twofold. A new filter will be sent to you every 6 months on the Water for Life plan. My filters are so clogged after 5 months that I leave a bottle to fill and come back for it. That''s how slow the water comes out. A five month plan would be more optimal. The second problem is replacing the filters. I dread replacing them every time. Unless you have applied some sort of lube to the housing you are going to have a fight on your hands getting the caps unscrewed from the bottom of the machine. It is all sharp plastic under there so as soon as you get one to let go you scrape the skin from you knuckles. I have an open wound right now from my efforts. Once you get the machine open then you have to fight and get the old filters out. One has a valve that faces you so that one comes out easily. The other faces away and all you have to grab ahold of it are little fins so get your pliers ready. If the moons are aligned properly the filter will come out in one piece. If not, the cap of the filter will come off and be stuck inside the machine. Good luck with that and get ready to lose some more skin. Go ahead and call customer service when this happens to get a really amusing solution from someone that has no idea how to remove this piece from the machine. I lube that side''s valve with olive oil before installing so hopefully it does not get stuck. My advice, wear sturdy gloves when changing the filter and have a full toolbox at hand.

A few notes about this unit:

-Brushed silver finish is not brushed silver, just a plastic which slightly mimics the look.

-Installation is really simple

My faucet diverter came broken, I called their support and they sent me out a replacement immediately and their support hours were pretty late which was convenient. So while I don''t yet have a working unit I am happy so far with the purchase and support I have received.

---Update:

The support got me a replacement diverter, it wasn''t the premium diverter the unit came with however it worked without leaking which was great. Customer service sent me a third diverter just so that I''d have the premium one too. I really appreciated their customer service.

I saw another review mentioning they had water leaking from the diverter, this is the same problem I had, water gushing everywhere. If you buy this and have that problem then just call their support, they will get you a fixed one.

The water from this tastes great! It is a slow flow but that is to be expected from this technology.

--Update 2:

About a year after my purchase, my working replacement diverter started leaking. I called support, however they were unable to provide me with a replacement due to my unit being out of warranty. They did offer to send me one if I subscribed to their replacement filter auto-ship program. I already needed new filters so I agreed. I was sent a new diverter, it leaked. I called, they sent another. It leaked. I called again, sending another diverter now. So at this point, having gotten faulty diverters over a year apart, their claim of a ''faulty batch'' this time around is not accurate as I apparently can get a faulty diverted 90% of the time I get a replacement. Based on that, I''d say they have QA or even design issues with their diverters so beware of that. They also don''t really have a solution beyond sending you one additional diverter at a time until the problem is resolved, this has proven to me to be highly inconvenient as I am unable to use my filter for 2 weeks now and I''m not convinced the next few diverters will work based on my experience with previous replacements. To be seen how this gets resolved and how long it will take. I changed my star rating to 3 stars due to my continued issue with the diverters.

This product is a great solution for those of us who are renting homes/apts and are not able to have a permanent system installed, want something better than pitcher filters, and don''t have the money or arrogance to buy bottled water daily.

Even though the actual housing body isn''t small, it''s very inconspicuous and I have forgotten that it is even there after a day. I initially thought the hose that runs up to the faucet would be tacky and annoying as well, but that too I stopped noticing after a day.

I wish there was a way to guage exactly how much water you use with these filters, because the "six months" or whatever ratings that filter makers give seem to be based on some "average" amount that the "average" person would use, but I have no idea if I''m near that average. Even when I hear the actual gallon amount, I have to believe it totally depends on the quality of your water to begin with and I have no way or interest in keeping track of how many gallons of filtered water are going through the filters. Well, the fact is my first set of filters lasted about 3-4 months before just becoming PAINFULLY slow (over a minute to fill up a glass).

The water tastes deliciously fresh and clean. I can''t say I notice a huge taste difference between this and the Brita pitcher filter, but I TRUST that it is doing a better job according to the company''s testings. I can''t figure a better way to tell for sure.

Bottom line it''s cheaper than drinking bottled water, but more expensive than Brita filters (if you buy in bulk on amazon like I used to), but the bet is that you are spending a little bit more for the assurance that you are filtering out way more than the Brita''s were ever intended to.

I''m not sure why everyone else has had a hard time swapping out filters. I thought it was a breeze. Sign up for their Water for Life program for a great discount on filters that are shipped to you automatically at set intervals.

Knocked one star off because the mechanism for switching to tap/filtered water does not automatically go back to tap anymore like it should. It''s not a problem in reality, but it''s not doing what it was designed to do...

My wife and I live in Harlem, USA. I have always thought that NYC water was great!. A quick internet search will reveal that our water comes from two sets of watersheds north of the city. They have large filtration plants and very old pipes. This filter removes tons of stuff!!! The filtered water looks and tastes great!

*v*v* Important note for NYC, and if your filtered water runs slowly *v*v*

After less than a month of running this counter-top filter, the filtered water began to come out slower and slower each day until it barely dripped out. We were getting frustrated and annoyed.

I emailed Aquasana, and the next day I received a response that said to call him. After playing a round of phone tag I learned quite a bit. Lots of people were having this problem, especially in the NYC area. He told me that the NYC area has a large amount of sediment in the water and this quickly clogs the filter. Sure enough, I removed the filters (supposed to last 6 months) and they were very dark with dirt! Aquasana shipped me out a temporary solution as they look into a permanent solution. The temporary solution is a small pre-filter attachment that he sent me for FREE with three replacement pre-filters and a replacement set of the main filters. All for FREE! And he said to call him when I need more pre-filters.

Right after installing the new main filters and the new pre-filter, the water came pouring out like on day one! After only a few days with the pre-filter that is in a clear container, the pre-filter is turning that dark brown--ewww! We were drinking that for years!!!!!!!

Aquasana has an awesome filtration system with over-the-top customer service! I highly recommend their product. Make sure you call them if you have any problems.

Bought this filter last week after reading many reviews on the AQ-4000. This model was very easy to setup and within minutes I had filtered water that tasted amazing. Removes all traces of chlorine taste and this was my goal. Very well built and easy to use. Turn on the water and flick the little diverter and BAM.....clean water. My favorite feature is the auto-shut off. When you are done using the filter the diverter switch automatically resets so that you don''t accidentally turn the faucet back on and use hot water and ruin the filters. I highly recommend this product to anyone looking for clean great tasting water.
